Abstract

The characteristics of heat pump evaporator are simulated using steady-state lumped parameter model. Considering the difference between the heat transfer of vapor and liquid refrigerant, the calculating method of the weighted average temperature in evaporator is revised, and the scope of the calculation is expanded to superheat section. The assumption of the chilled water outlet temperature is generally used in conventional simulation program and iteration of the temperature is necessary, which is a time-consuming process. In this paper, the outlet temperature of chilled water is determined by energy conservation and only the outlet enthalpy of refrigerant needs to be iterated, making the calculating process much fast. The effects of inlet parameters of chilled water on overall heat transfer and outlet chilled water temperature are examined using the new program. The prediction of simulation is compared with experimental results and good agreement obtained.
