摘　　要：研究低温环境下压缩机转速与送风量对补气式热泵空调的影响,进行采暖性能实验研究。在标准焓差和强化传热实验室中,设计换热器型号与低温制热的模拟工况,不同工况下利用红外传感器测试对各装填点进行测温。通过实验得出:在低温环境下,补气式热泵空调采暖性能可以通过改变压缩机转速和送风量进行调节,并且能够保证排气的温度在安全范围之内。In order to study the influence of penetration rate and air supply rate of compressor on the heating performance of air conditioning system with air supply heat pump at low temperature,an experimental study on heating performance was designed.The experimental device was set up in the standard enthalpy difference laboratory and enhanced heat transfer laboratory.The model of heat exchanger and the simulated working conditions of low temperature heating were designed.Under different working conditions,infrared sensor was used to test and measure the temperature of each set of desserts.The experimental results showed that:in the low temperature environment,the heating performance of the air-conditioning system can be adjusted by changing the compressor speed and air supply volume,and the exhaust temperature can be guaranteed within the safe range.
