MATLAB language was used to mathematically simulate the indoor unit of frequency conversion air-conditioner. Based on the simulation model, change of the refrigerant and air temperature with the length of coil pipe with the unit as an evaporator under refriger-ation condition and as a condenser under heating condition was studied and analyzed. The surface heat transfer coefficient on the refrigerant side and heat transfer coefficient of the in-door unit and the evaporation pressure distribution along the coil pipe were simulated and an-alyzed. The parameters under the two operating conditions were also comparatively analyzed.
