An ORNL heat pump design model was adopted to calculate and analysis the optimal amount of charging for dual cooling and heating air conditioner. The effects of heat transfer area and amount of refrigerant charge on the performance of air conditioner were investigated. Results show that under the conditions of heating and cooling, the system with larger heat exchanger area needs more charge than system with small heat exchanger area. For the given system, the optimal refrigerant charges of the cooling and heating modes were different. When indoor heat transfer area of the air conditioner was larger than the outdoor area, the difference optimal refrigerant charge between the cooling and heating modes tends to be reduced.
Key words： heat transfer area; dual air-conditioning; charge; refrigerant
