Constant temperature dehumidification controlling method for air conditioner

Abstract

The invention provides a constant temperature dehumidification controlling method for an air conditioner. When the air conditioner performs refrigeration and dehumidification, start or close of auxiliary electric heat is adjusted in time according to the change of environmental temperature, so that the indoor environmental temperature is effectively controlled to be in a constant level when humidity is removed, which reduces the environmental humidity and keeps the room temperature is in a stable state. The method realizes constant temperature dehumidification through the following steps: S1, the air conditioner enters a refrigerating operation mode; S2, after the air conditioner starts to refrigerate or operates for a period t1 or achieves a certain condition, the auxiliary electric heating is started; and S3, the compressor of the air conditioner is switched on / off according to a preset operation logics, the auxiliary electric heating is switched on / off according to the preset operation logics or a control command until the air conditioner is shut down. The constant temperature dehumidification controlling method can realize constant temperature dehumidification without increasing cost, and creates a comfortable environment for users.

Description

technical field [0001] The invention belongs to the technical control field of air conditioners, and in particular relates to a method for controlling constant temperature and dehumidification of an air conditioner. Background technique [0002] As we all know, when the existing air conditioner performs dehumidification operation, the air conditioning system generally performs cooling operation. In order to avoid the room temperature from dropping too much during dehumidification, at present, it is generally controlled to start or stop the compressor at intervals to ensure that the room temperature will not drop too much. quick. There are also some air conditioner manufacturers that add special throttling components to the refrigeration system or use special system construction methods to ensure that the air conditioner does not reduce the indoor ambient temperature too much while dehumidifying. However, the two methods commonly used at present have their own defects. Altho...

AI Technical Summary

Problems solved by technology

However, the two methods commonly used at present have their own defects. Although the first method adopts the intermittent working method for dehumidification, it will still bring people a relatively cold feeling during the Spring Festival when the temperature is not very high, resulting in uncomfortable feeling

Although the second method can achieve dehumidification while avoiding too much temperature drop, it needs to add some auxiliary components to the system, which greatly increases the product cost
