Abstract :
A steady-state lumped model of a fin-tube evaporator for carbon dioxide heat pump has been established in the paper. According to the model, a simulation program has been produced to calculate such parameters as the evaporator exchange heat, outlet temperature of CO2, enthalpy and so on. Then effects of air temperature, velocity and evaporation temperature on heat transfer and outlet parameters of carbon dioxide have been discussed, which is a reference to the design and optimization for CO2 evaporator.
