If to the valve of changes in temperature autogenous cutting parallel operation 30 and the end of input of the connection relationship between each indoor set 20a～20d, just on one side make whole indoor set 20a～20d in the heating installation pattern, turn round (operation 80), the cold air valve 32a～32d of Close All changes in temperature autogenous cutting parallel operation 30 on one side all opens the heating installation valve 31a～31d (operation 82) of changes in temperature autogenous cutting parallel operation 30 in addition.
In addition, on one side with each temperature sensor 37a～37d, measure near the temperature each heat exchanger indoor unit, standby on one side is to the temperature of the mensuration stabilisation (operation 84) that becomes.The stabilisation if the temperature of measuring with heat-exchanger temperature sensor 37a～37d becomes, then the microcomputer 38 of changes in temperature autogenous cutting parallel operation is just opened the 1st cold air valve 32a, closes the 1st heating installation valve 31a (operation 88) in addition.
If make the open and-shut mode change of the 1st heating installation valve and cold air valve sets, and, then confirm the measured value of each temperature sensor 37a～37d, calculate near the cooling amount (operation 90) of the 1st heat exchanger indoor unit through the stipulated time.Herein, the stipulated time, also can be different because of system, but be preferably set to the fully time of sense temperature decline.
As mentioned above, via the 1st heating installation valve 31a, after supplying with the gas refrigerant of HTHP with the indoor set of the 1st heating installation valve and the binding of cold air valve sets, close the 1st heating installation valve 31a, via the 1st cold air valve 32a, supply with to the indoor set that links with the 1st heating installation valve and cold air valve sets under the situation of liquid refrigerant of low-temp low-pressure, because the temperature difference of cold-producing medium is big, therefore the temperature variation by the temperature sensor perception also increases, and whether the result can hold easily variations in temperature.
Then, judge that temperature drops to whether the above indoor set of reference range is the 1st indoor set 20a (operation 92), and under the situation that drop in the temperature of the 1st indoor set 20a more than the reference range, the pipe arrangement that is judged as between the 1st indoor set 20a and the 1st heating installation valve and cold air valve sets links normal (operation 94).At this moment, reference range is or not that the situation that the other factors because of the open and-shut mode of change valve descends temperature is prepared for getting rid of from judge, this can select the value that suits by experiment.
If having judged the pipe arrangement between the 1st indoor set 20a and the 1st heating installation valve and cold air valve sets links normal, judge then whether the inspection to whole connection relationship finishes (operation 96), and when under the unclosed situation of whole inspections, change the open and-shut mode of next heating installation valve and cold air valve sets, check that pipe arrangement links (operation 98).
If in operation 92, it is not the 1st indoor set 20a that temperature drops to the above indoor set of reference range, the pipe arrangement that just is judged as between the 1st indoor set 20a and the 1st heating installation valve and cold air valve sets links mistake, shows warning (operation 100, operation 102) in display part (not shown).
Herein, pipe arrangement between so-called the 1st indoor set 20a and the 1st heating installation valve and cold air valve sets links mistake, refer to, the person of setting is the 1st indoor set 20a of pipe arrangement binding coupling on the 1st heating installation valve and cold air valve sets not, and has connected other indoor set on the 1st heating installation valve and cold air valve sets.
