Abstract: The paper built an pression integrated heat pump experimental platform.
Ammonia-water is used as absorption working pairs. The power of the heat pump is 50KW, the concentration of
the filled ammonia is 60%, pression ratio of pressor is 4, the temperature of the heat source and
outlet of hot water is 40 degrees centigrade and 70 degrees centigrade. The effects of different concentration of
dilute solution, different concentration of strong solution, heating temperature and COP on the system performance
are investigated.. After a lot of experiments ,it is proved that in the case of
