Abstract

The invention belongs to the field of air conditioner control and particularly relates to a constant-temperature dehumidification control method and system which do not need cost increase. Specifically, after a constant-temperature dehumidification function of an air conditioner is started and the temperature set by a user is reached in a heating or refrigeration mode, and dehumidification process is performed: inside-outside temperature difference is calculated in real time, and the initial operating frequency and a corresponding operating wind gear of a compressor are determined according to real-time indoor-outdoor loads for dehumidification. In the dehumidification implementing process, the frequency change and air speed change of the compressor are intelligently regulated according to temperature change in the operating process in real time, accordingly the indoor constant-temperature effect in the dehumidification process is achieved, and the comfort demand of a user is met.

Description

technical field [0001] The invention belongs to the control field of air conditioners, and in particular relates to a constant temperature dehumidification control method and a control system of an air conditioner. Background technique [0002] Under normal circumstances, the air conditioner must also be cooling during the dehumidification operation process. Therefore, when the indoor and outdoor temperature difference is large and the cooling load is large, the dual functions of cooling and dehumidification can be realized through ordinary dehumidification control, but when the indoor and outdoor temperature difference is small and the ambient humidity of the room is high, the cooling load is very large Small, through ordinary dehumidification will cause a rapid drop in room temperature, when the room temperature reaches a low level, users usually feel cold, that is, the air conditioner cannot operate and dehumidify according to the comfortable temperature set by the user. ...
