| Summary: | air cooling coils. This model uses the electrical algorithms are incorporated in software developed at the analysis are the basis for the development of the model. and energy consumption based on a simplified air-side model. average deviation of 3.5% and 1.2 'F, respectively. by testing it on data from two different buildings at Texas calibration of these parameters to data generated by a coil campus building and there was good agreement between the characteristics of the coil under study as well as for the clear picture of the heat transfer phenomena that occurs in coil. Field measured data combined with a theoretical conditions. different characteristics. Correlations are developed to Energy Systems Laboratory at Texas A&M University, College excellent in both cases, predicting the thermal resistance existing coils in the field is therefore needed in the Finally, the model is used to develop algorithms to simulate for application to water cooling coils with a range of have been developed in the past to characterize the overall heat transfer behavior of the coil. The coefficients heat transfer coefficient of this component. However, these heating, ventilating, and air conditioning (HVAC) industry. in conditioned space while minimizing the associated costs in the space conditioning area, providing, in this way, a manufacturer's simulation program allows the application of models require specific details about the coil construction Non-linear regressions are applied to the data to trace the obtained from the regressions account for the physical of operating the air conditioning system. Several models of the coils and the return water temperature with an physical characteristics. The resulting model is validated Precise understanding of the cooling coil in air handler predict the coefficients of the model and make it suitable properties of the fluids involved (air and water). The resistance analogy to treat the heat transfer process in the simplified engineering model suitable for application to simulate the response of the water-side to changes occurring Station, which is used to simulate building heating, cooling suitable for use with field measured data to characterize the cooling coil. The upgraded software was tested on a The objective of this study is to develop a simplified model the overall heat transfer coefficient of in-situ water-to- the resulting model to different types of cooling coils with the two most common chilled water loops in buildings: the This addition enhances the capability of the software to two-way valve and the blending station arrangement. These units is vital to assure the proper temperature and humidity which make them impractical for in-situ applications. A |
