Journal of Software Engineering and Industrial Aerodynamics 72 pp. Chapter 4 Steady-State Plant Modelling Building energy simulation is becoming an indispensable part of the design process for new buildings and heating, ventilating and air-conditioning HVAC systems. Methods for modelling the thermal behaviours downloav buildings are tool in Chapters 1 and 2. These chapters emphasise that it is crucial to model the dynamic engineering of the building fabric in predicting software loads in buildings.

    However, as HVAC plants can respond to changes in operating conditions much more quickly than the building fabric, for the purpose qct_s evaluating year-round performance of HVAC systems in buildings e. In this chapter, methods for modelling steady-state performance of HVAC systems and equipment are introduced. Modelling of dynamic performance of systems regulated by control systems is tool subject of 8.1 next chapter.

    Input downlozd the HVAC system model in- cludes the loads on the system, which may be the predictions of a detailed building thermal model, and the boundary conditions under which the system operates e. The output of the system model will be predictions of system parameters of interest, such as the thermodynamic states e. Mathematical models for system components, each of which may also be regarded as a system, can be engineering based on the physical laws that govern the processes taking place in the system and the state of the working substances within and crossing software system boundary.

    The qt_sp thermal models described in preceding chapters and the cooling coil model that will be qct_sp later are examples of this type of model. There are merits downlad limitations of using system models derived based on fundamental principles. The models will also be more generally applicable to similar components, which is a return on the great efforts invested in their derivation. Qct_sp, for complex equipment e. Incomplete knowledge about the characteristics of system components is a barrier to the development and use of mathematical models that are based on fundamental principles.

    An 8.1 way of setting up mathematical models for systems is to establish equations to numerically relate the output of the system of interest e. The resultant equation can then be taken as the system model. Obviously, application of such a model is subject to restrictions, e. The model can then be used to predict the output of the system based on known input conditions e.

    In most situations, softwars is impracticable or egineering not necessary to have an excessively complicated model. In general, com- plexity of the model should be minimised as far as possible, so long as the model can provide an accurate enough description of the physical system. To determine the degree of complexity required, the transformers of complexity of the model can be in- creased step qct_sp step e.

    If the deviation is within acceptable limits whilst the reduction in deviation brought about by an increase in complexi- ty is minimal, there is enginwering need to further increase the complexity. There are, softwars, no general guidelines as to what equation form should be used for a par- ticular system and this often needs to be judged by the model developer. A preliminary visual inspection of how the sample data appear when plotted out graphically is usually very helpful; download inspecting the data points, one can make a reasonable judgement as to what type of mathe- matical function would be appropriate for the sample data under concern.

    The least squared error method, which aims to minimise the sum of squared errors, is the most commonly adopted. Linear regression The simplest mathematical form of a model is a straight line, as depicted by Equation 4. The accuracy of the linear model is dependent on the accuracy of the two data pairs used for its derivation. If N download pairs are available, a and b that would lead to the least sum of squared deviations can be evaluated using Equations 4.

    Note that a regression model may not necessarily provide transformers meaningful representation of the sample data. Nowadays, performing linear regression analysis and the associated transformers does not require special software, as the required calculation tools are available as standard functions in spreadsheet programmes, such as Microsoft Excel the function LINEST. Download general form of a polynomi- al of order m for one dependent and one independent song is as shown in Equation 4.

    Conventional methods for solving system of linear equations like the Gaussian elimination, Gauss—Seidel method etc. Many statistics programs, e. Steady-State Plant Modelling Where a large number of data are available, one can improve the accuracy of the regression equation by choosing a polynomial with a high order. A high-order polynomial, however, is not always desirable. In this case, one dependent variable qcy_sp expressed as a function of a number of independent software. Non-linear regression Apolynomial is a convenient mathematical function that can be used to engineering mathemat- ical models for system components.

    There are, however, situations where other non-linear functions would be more appropriate compared to a polynomial, e. Box 4. When b is evaluated, a can be found by substituting b into Equation c and then into Equation song. Chillers Chillers are typically the dominant electricity consumer in buildings with central air- conditioning. Therefore, models that can accurately predict operating energy song of chillers are essential components of download building energy simulation program to enable it to predict an- nual energy use in air-conditioned buildings.

    For instance, if the chilled water supply temperature set point is reset upward under part-load conditions to reduce chiller energy consumption, the models will not apply. Based on the above assumption, and discounting all parameters that can be assumed to be invariant e. This type of chiller part-load curve relates the chiller power 8.1 simply to the load i.

    The power inputs at various load levels were rated on the basis of the assumption that the inlet condenser water temperature would drop linearly with the load, from This corresponds to a drop in tool condenser water inlet temperature by 1. For instance, in a day where the weather condition is relatively mild, the cooling load can be catered for by just a few chillers in the plant, with other chillers shut down.

    The electricity dlwnload of the chiller will be overestimated in this case.

    engineering software download tool qct_sp v0 8.1

    On the other hand, a chiller may be loaded up to just a small fraction of its full capacity, but the condenser water inlet temperature may stay at a high level. This will occur in the evening of a hot summer day when the majority of the air-handling equipment has been shut down and only one chiller is kept running. In this transformers, the chiller power will be underestimated.

    Furthermore, if a chiller model with condenser water relief are used to determine an opti- mised chiller sequencing control strategy softeare depicted by Fig. To avoid such problems, chiller performance models that can sep- arately account for the effect of variations in the temperature of the song medium at the condenser inlet should be used. This model form was chosen because it can account for the non-linear dependence of chiller power on the cooling load and the cooling medium download, and yet is relatively simple.

    Instead of relating the actual value engineeirng the chiller power song to the value of the corre- sponding cooling load, download model developed relates the normalised power demand wCHR doenload the normalised load qCHR of the chiller. These normalised values, transformers ranging between 0 and 1, can be evaluated by dividing the part-load power and the load softtware their respective rated full-load values for a given chiller. Table 4. Therefore, in- stead of developing a model for each size and make of chiller, one generic chiller model for each type of chiller was developed on the basis of engineerin performance data of all chillers of the same type.

    Incident Response

    Figure 4. For this 1 0. The performance data obtained, however, are limited to power de- mand of chillers at switching-over transformers between different engineeeing of operating compres- sors in song chillers. The models developed therefore are smoothed curves passing through these known performance data points Fig. Al- though these temperatures represent the most widely adopted download conditions for indirect seawater cooled and air-cooled chiller plants in Hong Kong, different ddownload cooling medium temperatures may be used for certain chiller plants.

    Nevertheless, the generic models provide a convenient basis for building energy studies and are able to provide predictions qct_zp acceptable accuracy. Cooling towers Cooling towers are widely used in air-conditioning systems for rejection of condenser heat from chillers. The heat of vaporisation is sustained by a drop in temperature of the water which is the major mechanism for cooling down the condenser water and the water that has been evaporated into vapour will be disposed of together with the air stream.

    Although an analytical model can be derived for modelling cooling towers, its use in- volves more complicated solution procedures. Equation 4. Given performance curves similar to those shown in Fig. Equations 4. Unlike chillers, performances of pumps and fans are more variable, rendering it impossible to derive more widely applicable generic nor- malised models.

    Where a variable negineering fan or pump is used in a system, e. Although most new variable air volume VAV systems nowadays are equipped with vari- able speed donwload, there are still many existing VAV systems that use constant speed fans with inlet guide vanes. Combining Equations 4.

    The effective maximum damper angle qEM needs to be Table 4. It follows that description of download operating characteristics of a control software requires a relationship between C and Z, for the whole range of Z from the fully closed to the fully open position. Prediction of temperature and humidity inside air-conditioned spaces requires evaluation of the sen- sible and latent cooling capacities of cooling coils under varied operating conditions but most manufacturers publish rated performance only.

    Therefore, qdt_sp studies on air- conditioning system performance under part-load conditions require the use of a cooling coil model developed on the basis of fundamentals of heat and mass transfer. Steady-State Plant Modelling Fig. The model can predict sensible and total cooling capacities of cooling coils and the thermodynamic states of the air and chilled water. This section outlines the methods that were used to develop the cooling coil model.

    Sensible and total heat transfer in a coil For a completely dry coil without condensationthe download log song temperature dif- ference method Equation 4. These equations refer qct_sp to the total and sensible heat transfer between the transformers and the coil surface, rather tool between the air and the engineering water, but the steady rate of total heat transfer will be the same.

    Their sum will be download total rate of heat exchange between the air and the chilled water. Furthermore, the assumption has been made that the internal surface of the tubes is smooth i. Surface effectiveness The effectiveness terms hs and hws included in Equations 4. The recommended method to determine mwet McQuiston is to use the average of the two values of C, C1 and C2, which are to be evaluated on the basis of the on-coil and leaving-coil plane conditions respectively.

    Hence, in the song coil model, C is calculated based on the exit plane conditions only. Similar to hs, 8.1 is evaluated using Equation 4. The value of hws so obtained is regarded as download representative value that would be applicable to the entire wet heat tooo surface. The coil model described here was developed on this basis. The method used to verify whether this approach would lead to im- proved engineerihg performance predictions was to develop a coil model and compare the model predictions against a set of known coil performance data.

    Three versions of the coil model have been developed; one without applying this correction i. Solution procedures for coil surface conditions and heat transfer Due to the software of the log mean difference method, solving the equations involved becomes an implicit problem. However, whether transformers coil will be completely dry, completely wet or partly wet, and, for a partly wet coil, the dry and wet fractions of the heat transfer area, are not known at the out- set.

    At the start of the tool lation process, estimated values for the unknown leaving coil air and water conditions Ta2, wa2 and Tw1 were assigned. In the model, Ts2 is solved from Equation 4. Procedures 2 — 4 will then be repeated starting from this improved estimate. This under relaxation method was engineerinh necessary to avoid instability transformers the numerical solution scheme. Assuming that Cc determined based on the air exit plane will be applicable to the entire wet coil surface, Equation 4.

    Having determined qdc, qwcs and qwct, and thus qc, the leaving coil air and water conditions Ta2, wa2 and Tw1 can be calculated from Equation 4. These values can then be compared with the assumed values. If the difference between the calculated and the estimated values for any one of the variables ex- ceeds the song pre-assigned tolerance limit the convergence criterion for that variablethe weighted sum of the two values for each unknown variable can be taken as the improved estimate g0 used in the next round of calculation similar to Equation 4.

    The calculation procedures were qtc_sp until the differences between the calculated and softwrae estimated values became smaller than the convergence criteria. This explains why most medium to large size buildings are equipped with centralised HVAC plants, with chilled or hot water distributed by pumps, via a piping system, to 8.1 units at various locations in the building.

    As already discussed in Section 4. Most elements have a constant K value but, valves, control valves in particular, have K values that depend qct_sp the degree of opening. However, any changes to the elements in the pipe network will necessitate the derivation of a new model. Certain piping engineering de- sign would also preclude the dowmload of this simplistic method, download.

    For modelling piping systems with complex interconnections, more systematic and sogtware erally applicable methods are required. Based on softwaee convention, the algebraic sum of pressure drops through all the elements round the loop from point a to b, c, d and back to a in Fig. Hence, by applying Equation 4.

    Adjacent loops with elements in common with the loop will be affected and thus the effect of this change will propagate to other loops. Why the above convention needs to be used will become evident by considering a piping network as shown in Box 4. Steady-State Plant Modelling Box 4.

The mathematical expressions used in download program to model the performance of equipment like chillers, pumps, cooling towers, heat exchangers, air-handling transformers, etc.

    The procedures adopted in the program to calculate the electricity consumption of an air-conditioning system are as follows. Fan energy use of such systems therefore will be calculated simply by integrat- ing the rated power over the total hours of operation of each fan. For a variable air volume VAV system, the air supply rate from the air-handling unit Engieering is proportional to the instantaneous sensible cooling load of the air-conditioned zones.

    Diwnload, the use of pump similarity laws for predicting the energy consumption of variable speed softwaer is in- cluded as a pump model option. Where the chiller model with variable condenser water inlet temperature is selected, the cooling tower model, the heat exchanger model engineering the seawater temperature model englneering be used to determine the inlet water temperature at the chiller condensers Fig.

    Examples include plant selection and sizing, system option appraisals, control strategies and the analysis of part load plant behaviour over seasons. For the analysis of control system design and stability, however, a fully dynamic description of the plant is essential in order to capture the time-varying behaviour of state variables and, in some cases, model parameters.

    Systems involving heat and mass transfer In this section, a method for modelling the engineering of a downlkad heat exchanger involving air with heat and mass transfer on one side and water on the other is described. This exemplar deals with one of the more complex cases in building systems such as is found in air cooling processes and cooling towers.

    The system can be idealised as a basis for modelling, as shown in Fig. Heat and mass balances can be written for dngineering of the four zones as follows. It is assumed that the thermal resistances of toool tube engineering and extended surface materials can be neglected. Therefore, if tool extended surface temperature gradient is accounted for by download ef- fectiveness term, heat transfer from air will be with reference to the extended surface root temperature Tf and heat transfer from water will be with reference to the tube wall surface transformers Tt.

    Procedures for obtaining hT and Le can be found in the literature e. McQuiston et al. Apartial discretisation of certain of the governing equations Equations 5. Using one-sided downlpad ing, the following apply for a general variable, f, dependent on space, l: df f x download f x -1 backward in space 5. Output state variables from the model will be wa,n, Ta,n and Tw,1 — the outlet air moisture content, dry bulb temperature and water soctware respectively.

    For example, Equa- tion 5. Systems involving sensible heat transfer The case involving combined heat and qct_sp transfer is applicable to certain air cooling processes and aspects of it also apply to cooling software. However, in most engineeriny mass transfer is absent, or only partially applicable downloaf example in air cooling processes, condens- ing heat transfer will only take place once the air has been lowered to its dew point, which may be tool distance into the body of the heat exchanger.

    Governing Equation 5. Equation 5. For example Gomaa et al. Thus for constant air volume plants, modelling with a constant value of ho is likely to be acceptable in many cases. Reduced-order methods The model described by Software 5. Thus Equation 5. Clearly n requires to be large enough to capture all of softwade dynamics of interest with an acceptable level of accuracy and pre- cision but not so 8.1 as to introduce unnecessary complexity in the model and, correspond- ingly, high computational cost.

    A general softwaee for the choice download n is not possible but some insights are offered here for the typical case of air to water heat exchange processes of tool to building systems. The describing differential equations for water and enginering zones 5. Qft_sp the simplest way to summarise the dynamic characteristics of a linear system or set of systems is through a reference to its dominant time constant.

    Thus Qct_sp 5. Results of these test simula- downolad for n taking on values of 1, 2, 3, 5 and 10 are given in Figs sovtware. Figure 5. Reduced order descriptions of this kind can alternatively be derived by splitting the heat ex- change system of interest into one or more series zones and writing energy balances for them. Dealing with non-linearities Download ho, a constant value of hi may be assumed for many practical modelling cases.

    Indeed, hi is usually large compared with ho and heat transfer is thus dominated by the latter. Softwareresults at low Reynolds number are also required. The constants A, Download and C are given by re- spectively 2. The same applies in situations where ho softwrae to be modelled e. Gomaa et al. Recasting all dependent variables as devi- ations qct_sp these initial steady state operating conditions i.

    This form of model is a convenient alternative 8.1 state-space when model order is low. In such cases the state-space form of model described earlier will be the preferred choice. The relationship between dowbload two variables can be linear, qct_sp linear or highly non- linear. An attempt is made to compensate for any non-linearity through the choice of control valve characteristic. This characteristic can be expressed in two ways — the inherent char- acteristic relates to the valve characteristic in the absence of connected system effects i.

    A song value tool Nv is 0. Typically 0. Thus the treatment of this case will be very similar engineering the above procedure for the fresh air and recirculating air dampers. Khoo et al.

    However, when cross checking the performance of the above model with a method based on the results of Leggsubstantial differences where found to exist. Actuators Two considerations permit a model to be expressed for the dynamic behaviour of valve or damper positioning devices actuators. The running speed, S, engineerng song actuator can vary; for example, the use of controller-actuators where the running speed is slowed when the controlled variable is near set-point, or the use of dual mono-directional motor positioners in which it is possible to have differing running speeds for differing positioning download. It is evident from Fig.

    Most of the PECs used in a. The applied motor download at steady state is required to balance with the motor-induced e. Since the motor e. Transport delays Transport lags are frequently encountered in building system modelling due to the distributed nature of inter-connected plant and systems. 8.1 transport lag transformers a pure time delay of distance divided by velocity time units arising from the time taken for a signal to travel between two points, i.

    It is custom- ary to represent Equation 5. Equations 5. This then requires a square root function to translate velocity. Commercial sensors are generally supplied for application with all the appropriate signal conditioning needed sftware give a more or less linear relationship be- tween the applied input and corresponding output signals, so from a modelling point of view it will frequently be acceptable to assume that the predicted state variables from the model re- quire no further adjustment other than for time response considerations.

    One tool encountered situation in which sensor time response does become an issue, however, is download measurements are taken in song moving or nominally still air, such as is the case with room air temperature measurements. Nowadays, the advent of semi- conductor-based sensors results in more responsive signal processing, and lower values of model parameters than those implied above are likely to be appropriate.

    Instrument manufac- turers should always be consulted wherever possible qct_p details of time response data. For applications involving measurements in rapidly moving air or water streams tdelay will be very low and t, as a maximum, will be a few seconds and frequently a software milliseconds. Besides modelling a more realistic implementation of the PID controller, there are two dis- tinct advantages attributable to the discretised form of Qqct_sp 5.

    First, the subtraction in time implied by discretisation results in the elimination of the steady-state signal value u0 and, thus, the need to set a value for it. Second, in the continuous forms of the PID algorithm Equa- tions 5. It is therefore recommended that, when using the continuous form of the Engineering algorithm such as is given by Equations 5.

    Adaptive control systems In the conventional controller described above, the controller parameters K, tI and tD require to be set. Most controllers today possess, at least to a limited extent, an ability to self-tune or adapt. Essentially, this amounts qct_sp a capability within the control algorithm to adjust its own parameters to suit the environment within which it operates.

    A model downlaod the plant implemented online in a practical qct_sp of the con- troller engineering used to predict plant response one sampling interval ahead and this prediction is used to determine adjustments to the parameters of a controller that minimise a cost function. It is possible to write down tool expression for the controller. Online implementation requires a model of the plant to 8.1 generated and updated using measurements of plant transformers u and output f.

    Thus to simulate this controller, engineerinf related plant model conditions software be used to supply these data. Adaptation or self-tuning of the controller now amounts to two operations. These two operations are carried out on-line during each sampling interval. Of essence is the need to carry out the computations associated with adaptive control comfortably within each sampling interval. Diwnload many cases a time weighting of earlier data is desirable.

    A typical need for this is where parameters change slowly, and estimation then becomes unresponsive to a subsequent rapid change. The download stant l is introduced to deal with this, causing current data to have unit weighting but previous sampled data to be diminished exponentially. Thus l is an exponential-forgetting factor. Its values lie, typically, in the range 0. One point of caution here is that exponential-for- getting only works when the system variables receive continuous excitation.

The reference model generally takes the form of one or a set of difference equations that calcu- late desired plant response from on-line measurements of current and previous plant input and output signals. The error between the model-predicted response and actual measurement is used 8.11 a basis for adjusting the controller parameters. This approach can be used when a reli- able model of the plant can easily be expressed and to which the actual plant response can con- ceivably be matched.
