| Abstract: | A new micro-channel gas cooler for CO2 heat pump water heater was designed.The calculation program was developed using finite elements method.Fluid flow and heat transfer processes in both sides were analyzed.And the influences of major parameters on gas cooler and the pressure drop of the CO2 side were discussed.The model developed in this paper could be used for the optimal design of gas coolers and it is expected to offer useful guidelines for system design and its optimization. |
