The invention relates to a direct heat exchange type heat pump air conditioning system of a lubricating oil waste heat source. The direct heat exchange type heat pump air conditioning system comprises an internal circulation fan, a first heat exchanger, a four-way reversing valve, a compressor, an expansion valve, a first controlled valve, a second controlled valve, a third heat exchanger, a third controlled valve, a fourth controlled valve, a lubricating oil tank, a pump and a transmission case; and lubricating oil in the transmission case is high-temperature fluid. According to the system, lubricating oil waste heat is directly utilized by heat pump circulation under a cold day condition, and the temperature of a cabin can be rapidly controlled; a refrigerating system, a heating system and a lubricating oil system of a helicopter are comprehensively and integrally designed, so that the mass of the system is effectively reduced; and the flow distribution of working media or lubricating oil is controlled through the first controlled valve, the second controlled valve, the third controlled valve and the fourth controlled valve, and heat flow is matched.

    本发明涉及一种滑油废热源的直接换热式热泵空调系统,包括内循环风机、第一换热器、四通换向阀、压缩机、膨胀阀、第一受控阀、第二受控阀、第三换热器、第三受控阀、第四受控阀、滑油箱、泵、传动箱;所述传动箱内的滑油为高温流体。本发明冷天条件下滑油废热被热泵循环直接利用,能够快速地对舱室温度进行控制;通过对直升机制冷系统、制热系统以及滑油系统进行综合一体化设计,有效降低了系统质量;通过第一受控阀、第二受控阀、第三受控阀、第四受控阀对工质或滑油流量分配进行控制,对热流进行匹配。
