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.
