Abstract

CO2 gas coolers are widely applied in CO2 refrigeration, air conditioning and heat pump systems. The controls, operations, modelling and designs of the CO2 gas coolers are important to the performance of their associated systems and thus are discussed extensively in this chapter. For the controls, it is explained the reason for the existence of optimal heat rejection pressure and how to predict and control the optimal pressure at different operating conditions. For the operations of cooling processes, some important correlations from literatures for the heat transfer and hydraulic calculations are introduced and discussed. In addition, different modelling methods for the gas cooler performances are discussed and compared. The modelling with distributed method is purposely introduced together with model validations and simulation results. Furthermore, the application of CO2 gas coolers in automobile is explained and some design options are recommended.
