This paper studies the use of air-conditioning condensation heat first, and then studies minitype air-conditioning condensation heat reclaim system. We use the test-bed which refits by haixin company' KFR--60LW/BP, to test refrigerant temperature in different flux of cooling water, the cooling water temperature passed in and out condensator, the cold water temperature and the compressor power in different flux of cooling water. And we also analyze these experiment data. In the experiment, when the flux of cooling water is 116 L/h, the outlet c...
