Abstract

The casing evaporator with R134a as refrigerant was numerically simulated by simulation software. The influence of the change of convective heat transfer coefficient at the refrigerant side on the heat transfer area of the evaporator, the parameters at the refrigerant side and COP of the refrigerant system were studied. The simulated data shows that refrigerant convective heat transfer coefficient for each 100 W•m^-2•°C^-1, the evaporator of the heat transfer area after the first fast slow decreasing trend, the range is between 0.58% and 2.67%, refrigerant mass flow load increase after first fast and slow, the range is between 0.18% and 1.88%, convective heat transfer coefficient of refrigerant side load increase after first fast and slow, the range is between 0.11% and 0.98%.The convection heat transfer coefficient on the refrigerant side increased, and the COP of the refrigerant system increased, which was beneficial to improve the operation performance of the system.
