PURPOSE:To realize an improvement of efficiency and proper temperature setting by balancing a required amount of a refrigerant in an evaporator and a supplied amount of a refrigerant to the evaporator upon alteration of cooling capability. CONSTITUTION:There are provided on a controller 30 first storage means 7 for storing time the combustion amount of a burner of a regenerator is altered, second storage means 8 for storing a predetermined time difference (t), measurement means 9 for measuring time since alteration of a combustion amount, and control means 40. The control means 40, when alterations of set temperature and the like are inputted and cool ing capability is altered, alters capability of a fan 11 fitting the same to set temperature after the lapse of the time difference (t) since alteration of the combustion amount of a burner. Accordingly, upon alteration of capability of the fan a required amount of a refrigerant in an evaporator and a supply amount of a refrigerant to the evaporator can be balanced whereby efficiency is improved without producing invalid refrigerant and proper temperature setting is realized. |
