Hot pump type double make air conditioning do not open report complementary heat, the wind that blows is not hot, have a variety of factors, can begin to overhaul from below a few respects.
① sees compressor whether work. Have the word that pincerlike expresses, with pincerlike the watch is measured, the working electric current of air conditioning (do not open report complementary heat) , if measured value is controlled in 5A, so OK and affirmatory compressor is working. 
If at hand does not have pincerlike watch, can rely on earthy method to judge only. Open a mechanism to heat up, hear the voice of the machine outdoor, can judge compressor to whether work probably; Moreover, wait for switch on the mobile phone 3 after arriving 5 minutes, close machine... if the machine outdoor gives out ＂ to whistle... the air current sound of ＂ , and sound by strong slacken, last probably 2 -- 4 seconds, explain compressor already worked.
② if compressor does not work, can check circuit of lukewarm bag of indoor machine feeling, compressor, capacitance, heat to protect further implement etc.
③ compressor is normal, whether does reexamination lack cold intermediary. Open a mechanism to heat up, if with copper pipe of connective of the machine outdoor, feel changes without temperature, or tie hair frost, explain lack refrigeration agent. 
④ is additional, if open a mechanism to heat up, give sirocco first, after moving period of time, the feeling does not have sirocco again. To this kind of circumstance, observe the airplane outdoor first, if the machine outdoor is frozen by ＂ ＂ , because,be probably ageing of fan of the engine outdoor, rotate speed is too low, it is the machine outdoor comes loose probably heat becomes warped piece too dirty, it is to change frost sensor device to have a problem probably, cause the difficulty that change frost thereby, make the machine outdoor is frozen, bring about cold heat incommutable, air conditioning cannot make heat normally.
Individual viewpoint, offer reference, insufficient place, ask point out mistakes so that they can be corrected.
