Air conditioner

Abstract

The invention provides an air conditioner. The air conditioner comprises a refrigerant pipeline, a compressor, a condenser, a throttling device and an evaporator, and further comprises a bypass pipeline, a dehumidifying condenser, a change-over valve and a humidifying device, wherein the compressor, the condenser, the throttling device and the evaporator are connected on the closed-loop refrigerant pipeline in sequence; the bypass pipeline comprises a first end and a second end; the first end and the second end of the bypass pipeline are connected on the refrigerant pipeline between the condenser and the evaporator; the dehumidifying condenser is connected on the bypass pipeline; the change-over valve is connected with the bypass pipeline, and used for controlling the opening and the closing of the bypass pipeline; and when the air conditioner is under a refrigeration working state, the humidifying device can be used for humidifying air. The air conditioner disclosed by the invention can be simultaneously suitable for a low-temperature high-humidity environment and a high-temperature drying environment; and during dehumidifying in the low-temperature high-humidity environment, the temperature of indoor air is not reduced, and the humidity in air can be compensated during refrigerating in the high-temperature drying environment, so that the comfort of using the air conditioner disclosed by the invention by the user is guaranteed.

Description

technical field

[0001] The invention relates to the field of household appliances, in particular to an air conditioner. Background technique

[0002] At present, the existing mobile air conditioners have both cooling and dehumidification functions, but the dehumidification mode of the air conditioner is roughly the same as that of the cooling mode. The difference is that the indoor fan is forced to operate at a low wind speed during dehumidification. The disadvantages of this type of dehumidification are: on the one hand, the dehumidification amount per unit time is small and the power consumption is large, and the overall dehumidification efficiency is low; Ambient temperature, use in a low temperature and high humidity environment will affect the comfort of the user when using the product; on the other hand, the water vapor in the air will condense on the evaporator during the normal cooling of the mobile air conditioner, which will cause the humidity in the air to drop ,...
