Abstract

The invention relates to an air cooled heating pump test system. An air treatment box is arranged inside a tested unit environment chamber, and a heat balance water tank is arranged outside the tested unit environment chamber; and cold capacity and heat are distributed and balanced between a surface cooler in the air treatment box and the heat balance water tank through the tested unit and an external cold source or an external heat source, so that requirements on water supply in different temperature regions is met. In a test process, control of the temperature and the humidity of the whole environment system can be executed by adjusting the flow of coolant water entering the air treatment box in the test chamber without extra heat source input. The air inlet temperature of a condenser of a large-size air cooling and heating pump unit can be independently controlled in different regions; in a season that outdoor temperature is relatively low, a working condition required by test of the tested unit can be realized by only controlling the air inlet amount and the air exhaust amount getting into and getting out of the test chamber; and the test energy consumption of the unit can be saved by 50 percent. The system can be used for product development experiments and test of the performance of the tested unit of an air cooled heating pump production line.
