Title: | Predictive and diagnostic aspects of a universal thermodynamic model for chillers | Authors: | Gordon, J.M. Ng, K.C. |
Issue Date: | Mar-1995 | Citation: | Gordon, J.M.,Ng, K.C. (1995-03). Predictive and diagnostic aspects of a universal thermodynamic model for chillers. International Journal of Heat and Mass Transfer 38 (5) : 807-818. ScholarBank@NUS Repository. | Abstract: | There are fundamental aspects of chiller behavior-characterized by the chiller coefficient of performance as a function of cooling rate and coolant temperatures-that pertain to all refrigeration devices. We review, further develop, and validate against extensive experimental measurements a simple thermodynamic model that captures the universal aspects of chiller behavior. The model provides a procedure for predicting chiller performance over a broad range of operating conditions from a small number of selected measurements, as well as a diagnostic tool. The accuracy of the model is illustrated for reciprocating, centrifugal and absorption chillers. Universal aspects of chiller behavior are further illustrated with less conventional small-scale cooling devices such as thermoacoustic and thermoelectric chillers. © 1995. | Source Title: | International Journal of Heat and Mass Transfer | URI: | http://scholarbank.nus.edu.sg/handle/10635/58631 | ISSN: | 00179310 |
