Embodiment Construction
[0051] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0052] The main core idea of the present invention is that during the dehumidification and cooling operation of the air conditioner, when the temperature difference between the indoor ambient temperature and the target temperature is less than the preset temperature, the initial frequency of compressor operation is determined after obtaining the indoor and outdoor temperature difference, and at the same time the indoor fan is operated The wind speed drops to the preset wind speed. Then the adjustment condition satisfied by the temperature difference between the current indoor ambient temperature and the target temperature is obtained, and the operating parameters of the air conditioner are adjusted. Therefore, the purpose of dehumidification of the air conditioner at a constant temperature is realized, the comfort o...

The invention discloses an air conditioner constant temperature dehumidification control method. The air conditioner constant temperature dehumidification control method comprises the following steps: when an air conditioner is in a dehumidification mode, controlling the air conditioner to start refrigerating, starting an indoor fan, and detecting an indoor environment temperature; when the temperature difference between the detected indoor environment temperature and the target temperature is lower than a preset temperature, acquiring an outdoor temperature difference; on the basis of the indoor temperature difference and the outdoor temperature difference, determining an initial frequency of starting a compressor, and reducing the running air speed of the indoor fan to a preset air speed; acquiring a temperature difference between the existing indoor environment temperature and the target temperature; on the basis of regulation conditions met by the temperature difference between the existing indoor environment temperature and the target temperature, regulating operation parameters of the air conditioner. The invention further discloses an air conditioner constant temperature dehumidification control device and an air conditioner. With the air conditioner constant temperature dehumidification control method, the air conditioner constant temperature dehumidification control device and the air conditioner, an indoor constant environment temperature or a substantially slow temperature drop during the dehumidification process of the air conditioner can be achieved, accordingly increasing the comfort level of using the air conditioner by users. Moreover, no additional parts such as dehumidification valves are required for the air conditioner, thereby reducing 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, and an air conditioner. 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 the general dehumidification method; but when the indoor and outdoor temperature difference is small, the indoor ambient temperature will be caused by the general dehumidification method. The rapid drop affects the comfort of the user when 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, th...
