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.
