Problems solved by technology

[0002] Most of the air-conditioning products on the market now only have a set of circulation system, in which only a single number of evaporators, condensers, expansion valves and other main components are installed, and air-conditioning functions such as refrigeration and dehumidification need to rely on this circulation system to complete. In the actual use process, the existing air-conditioning products cannot achieve the optimal operation status of multiple functions such as cooling and dehumidification at the same time. The required temperature conditions, when the

Embodiment Construction

[0021] In order to clearly illustrate the solutions in the present invention, preferred embodiments are given below and detailed descriptions are given in conjunction with the accompanying drawings. The following description is merely exemplary in nature and is not intended to limit the application or uses of the present disclosure. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0022] Such as figure 1 As shown, the present invention provides a control method for an air conditioner, the steps comprising:

[0023] S101. Obtain the set humidity of the indoor unit 1 and the indoor ambient humidity; specifically, the set temperature and the set humidity are directly obtained from the air outlet temperature and humidity set by the user through the remote control or the control panel, and the ambient temperature and the ambient humidity are It is obtained through the temperature detection ...

Abstract

The invention discloses a control method and device for an air conditioner and the air conditioner. The control method includes the steps of obtaining the set humidity of an indoor unit and the indoor environment humidity; calculating the humidity difference value between the set humidity and the environment humidity, and matching the humidity difference value with the preset humidity difference section to generate matching results; and according to the matching results, controlling fans of a plurality of heat exchange and air supply units to be operated at low speed or medium speed and expanding the opening degree of expanding valves. According to the control method, when the air conditioner is operated in a refrigeration and dehumidification mode, the opening degree of the expanding valves corresponding to different air outlets can be adjusted according to the indoor environment humidity, and therefore the air conditioner can meet the target needs of users for refrigeration and dehumidification simultaneously.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a control method and device for an air conditioner and an air conditioner. Background technique [0002] Most of the air-conditioning products on the market now only have a set of circulation system, in which only a single number of evaporators, condensers, expansion valves and other main components are installed, and air-conditioning functions such as refrigeration and dehumidification need to rely on this circulation system to complete. In the actual use process, the existing air-conditioning products cannot achieve the optimal operation status of multiple functions such as cooling and dehumidification at the same time. The required temperature conditions, when the indoor temperature is low and the humidity is high, it cannot meet the requirements of blowing without cooling and dehumidification, or when the temperature is high and the humidity is high, it cannot quickl...
