Embodiment Construction
[0059] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0060] The main core idea of the present invention is that, during the cooling and dehumidification operation process of the air conditioner, the current frequency of compressor operation is determined through the temperature difference between the indoor ambient temperature and the outdoor ambient temperature, and the temperature difference between the indoor ambient temperature and the indoor target temperature, and the indoor temperature is determined. The current wind speed of the fan operation; control the frequency of compressor operation and the wind speed of the indoor fan during the dehumidification process of the air conditioner, so that rapid dehumidification can be achieved, and at the same time, the indoor environment can be kept at a constant temperature or cooled very slowly during the dehumidification ...

The invention discloses a thermostatic dehumidification control method of an air conditioner. The thermostatic dehumidification control method of the air conditioner includes the following steps of controlling the air conditioner to operate in a cooling way when the air conditioner enters a dehumidification mode, and checking indoor environment temperature and outdoor environment temperature; acquiring temperature difference delta Tf of the indoor environment temperature and the outdoor environment temperature and temperature difference delta Tc of the indoor environment temperature and set temperature; determining the current operation frequency of a compressor according to the temperature difference delta Tf and the temperature difference delta Tc; determining the current operation wind speed of an indoor fan according to the temperature difference delta Tf and the temperature difference delta Tc; controlling the air conditioner to operate according to the determined current frequency and current wind speed. The invention further discloses a thermostatic dehumidification control device of the air conditioner. The thermostatic dehumidification control method and device of the air conditioner achieve thermostatic dehumidification of the air conditioner and increase the dehumidification amount; meanwhile, the thermostatic dehumidification control method and device of the air conditioner reduce the cost of the air conditioner.
Description
technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner constant temperature dehumidification control method and device. Background technique [0002] During the cooling and dehumidification operation of the air conditioner, when the indoor and outdoor temperature difference is large, the cooling and dehumidification functions can be realized through ordinary dehumidification; but when the indoor and outdoor temperature difference is small, the room temperature will drop rapidly through ordinary dehumidification methods, affecting The comfort of the user using the air conditioner. [0003] At present, the general constant temperature dehumidification method for air conditioners is to add a dehumidification valve to the indoor heat exchanger of the air conditioner. During the constant temperature dehumidification process, the dehumidification valve is closed, the throttling device of the air conditioner is opened, an...
