PURPOSE:To ensure comfortable heating and cooling by estimating operation-off temperature based upon a room temperature change between the room temperature upon operation-off and that after the lapse of delay time of compressor operation starting and based upon a temperature difference between set temperature and the room temperature after the lapse of the delay time of the operation starting. CONSTITUTION:A compressor 10 is rotated at predetermined revolutions in operation, and starts its operation as room temperature Tr becomes operation-on temperature Ton while it stops its operation as the room temperature Tr becomes operation-off temperature Toff. A room temperature control part corrects the operation-off temperature Toff until that by estimating the proper operation-off temperature Toff until predetermined delay time Td is lapsed since the compressor 10 stops after the room temperature Tr becomes the operation-off temperature Toff. Then, the corrected operation-off temperature Toff is used to judge whether or not the room temperature Tr reaches the operation-off temperature Toff. Operation and interruption of the compressor 10 is fuzzy-controlled by correcting the operation-off temperature Toff at all times in such a manner, whereby the room temperature Tr is adjusted to about set temperature Ts.
