Title:
COOLER AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2017/138167
Kind Code:
A1
Abstract:
Provided are a cooler and an air conditioner with which it is possible to appropriately prevent the device from reaching an overload operating state, even when an outside air temperature sensor and/or an outdoor heat exchanger temperature sensor is not provided. An air conditioner 1 is equipped with: a refrigeration cycle (cooling mechanism) having a compressor 52; a power calculation unit 22 that calculates power values for the compressor 52; and a rotational frequency control unit 21 that controls the rotational frequency of the compressor 52. The rotational frequency control unit 21 determines whether the refrigeration cycle is in an overload state on the basis of the power values calculated by the power calculation unit 22 and the rotational frequency of the compressor 52, and controls the rotational frequency of the compressor 52 on the basis of the determination result.
