Claim 8:
9. An operation method of the fabricated air conditioner wall according to claim 1, comprising:
1) When the heat pump system is in a cooling mode, a refrigerant circuit comprising:
the refrigerant being compressed by the compressor (13), and a refrigerant circuit after the compression of the compressor (13) being cooled by the wall-buried pipe (21);
if a temperature of the refrigerant is lower than an outdoor temperature after the refrigerant is cooled by the wall-buried pipe (21), the refrigerant circuit bypassing the outdoor heat exchanger (16);
if the temperature of the refrigerant is higher than the outdoor temperature after the refrigerant is cooled by the wall-buried pipe (21), the refrigerant circuit being re-cooled by passing through the outdoor heat exchanger (16); and
after being cooled, the refrigerant being further cooled by passing through the condensate water tank, then entering the indoor heat exchanger (3) through the throttle valve (10) for expanding and absorbing heat, and finally returning to the compressor (13); and
2) when the heat pump system is in a heating mode, the refrigerant circuit comprising:
after being compressed by the compressor (13), the refrigerant entering the indoor heat exchanger (3) for releasing heat and then passing through the throttle valve (10) for expanding and cooling;
if a temperature of the precast wall is lower than the outdoor temperature, the refrigerant after passing through the throttle valve (10) absorbing heat only through the outdoor heat exchanger (16);
if the temperature of the precast wall is higher than the outdoor temperature, the refrigerant after passing through the throttle valve (10) absorbing heat again through the outdoor heat exchanger (16) and the wall-buried pipe (21); and
the refrigerant returning to the compressor (13) after absorbing heat.
