Problems solved by technology

[0007] However, the cooling operation in the "sleep mode" of the air conditioner described in Patent Document 1 is performed at night when the outdoor temperature is low, and the room temperature gradually rises. The switching (ON / OFF) of the room temperature is easy to fluctuate (hunting: oscillation phenomenon), and the room temperature control may become unstable.
In addition, sometimes it is necessary to perform heating-inclined dehumidification operation, but heating-inclined operation cannot be performed in cooling operation or over-throttle cooling operation.

Embodiment Construction

[0024] Hereinafter, an air conditioner according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0025] Fig. 1 is a block diagram of an air conditioner according to an embodiment of the present invention. In addition, in this embodiment, the cooling operation of a so-called "reheat dehumidification type" air conditioner having two indoor heat exchangers will be described as an example.

[0026] As shown in FIG. 1 , the air conditioner 1 of the present invention has a refrigeration cycle (refrigeration cycle) 2 in which a refrigerant is circulated, and the refrigerant compressed by the compressor 3 of the refrigeration cycle 2 to become a high-temperature and high-pressure refrigerant passes through a four-way valve 4 and is compressed. The refrigerant is sent to the outdoor heat exchanger 5 as a condenser, where it is condensed and liquefied by exchanging heat with the outdoor air to become a high-temperature and high-...

Abstract

The present invention provides an air conditioner which can operate continuously at night when the outside air temperature is lower without opening and closing the compressor frequently and restrain the indoor humidity generating abrupt change to realize the comfortable sleeping environment. The air conditioner has the reheating dehumidify function of motion for heating the room air using the first indoor heat exchanger and for cooling using the second indoor heat exchanger, also includes the sleep pattern running control device for processing control, when in operation with a desuperheating zone dropping from the target temperature and a heating zone wherein the indoor temperature rises. The sleep pattern running control device has the operation switch control mode for processing refrigeration operation in the desuperheating zone, and being switched from the refrigeration operation to the reheating dehumidify operation starting at the control in the heating zone.

Description

technical field [0001] The present invention relates to an air conditioner, and more particularly to an air conditioner provided with a sleep comfort mode operation control device and operated in a cooling zone where the indoor temperature drops from a target temperature and a warming zone where the indoor temperature rises from the cooling zone. Background technique [0002] Generally, air conditioners require different air conditioning controls when the user (user) is sleeping and not sleeping. Therefore, a "sleep mode" is set as a cooling operation mode (cooling operation mode) suitable for sleep, and a cooling operation based on this "sleep mode" is performed. [0003] The cooling operation based on the sleep operation mode set in the conventional air conditioner, after operating for a certain period of time at the target temperature initially set by the user, the room temperature is gradually raised, so as to comply with the decrease in the amount of metabolism of the h...
