Abstract

The invention provides an air conditioning device which can keep a dehumidification function when the outdoor temperature is low and can guarantee comfort of indoor people. The air conditioning device (10) comprises indoor heat exchangers (50), indoor fans (55), indoor temperature sensors (96), outdoor temperature sensors (95) and indoor control parts (92). During refrigerating operation of the indoor control parts (92) in an automatic mode, a target refrigerating temperature of a target indoor temperature is changed together with the outdoor temperature.

Description

technical field [0001] The invention relates to an air conditioning device. Background technique [0002] Conventionally, an air conditioner is used to perform a cooling operation to perform a dehumidification function. In this cooling operation, the indoor heat exchanger in the air conditioner functions as an evaporator, and the evaporating temperature is set to a temperature lower than the dew point of the indoor air to perform dehumidification that removes moisture contained in the indoor air. effect. [0003] However, when the cooling operation is performed so that the indoor heat exchanger acts as an evaporator to dehumidify, the indoor temperature gradually decreases. When the room temperature drops below the target temperature, the compressor stops running and is in a thermo-off state. Normally, the cooling target temperature when operating in automatic mode is fixed at 28°C. If the cooling operation is performed on a day with high humidity and low air temperature ...
