Window air conditioner and its control method and control device

Abstract

The invention provides a window type air conditioner and a control method and device thereof. The control method of the window type air conditioner comprises the steps that the outdoor environment temperature is detected; whether the detected environment temperature is smaller than the preset environment temperature or not is judged, and if yes, an air deflector of the window type air conditioner is controlled to be opened; the preset temperature interval to which the detected environment temperature belongs is judged, the preset open degree value corresponding to the preset temperature interval is obtained, and the lower the environment temperature is, the larger the corresponding preset open degree value is; the air deflector is controlled to be opened to the preset open degree value; the surface temperature of a heat exchanger on the indoor side is detected; and the open degree value of the air deflector is adjusted according to the detected surface temperature. According to the provided control method of the window type air conditioner, the open degree value of the air deflector is jointly adjusted according to the environment temperature and the surface temperature of the heat exchanger on the indoor side so that the air volume of a heat exchanger on the outdoor side can be adjusted, thus, the condensing temperature and the condensing pressure of the outdoor side under the low-temperature refrigeration condition are improved, and normal continuous operation of the product is ensured.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, and more specifically, to a control method for a window air conditioner, a control device for the window air conditioner, and a window air conditioner including the control device for the window air conditioner. Background technique [0002] Existing ordinary window air conditioners generally have a cooling working environment temperature of 18-43°C, but for some special places and different weathers, cooling is still required when the outdoor ambient temperature is lower than 18°C. For example, large-scale communication equipment rooms, power distribution equipment, and electronic equipment workshops. The machines and equipment in these places will continue to heat up during operation, which will affect the life of the equipment. When the temperature is low, the condensing temperature and condensing pressure on the outdoor side will be very low, and the refrigerant pressure will...

AI Technical Summary

Problems solved by technology

For example, large-scale communication equipment rooms, power distribution equipment, and electronic equipment workshops. The machines and equipment in these places will continue to heat up during operation, which will affect the life of the equipment. When the temperature is low, the condensing temperature and condensing pressure on the outdoor side will be very low, and the refrigerant pressure will be lower after throttling, so that the evaporation temperature will be low after entering the indoor evaporator, which will easily lead to frosting and condensation on the indoor evaporator. Ice will reduce the air volume on the indoor side, worsen the cooling effect, and may even cause water leakage on the indoor side, and the incomplete evaporation of the refrigerant on the indoor side will cause the liquid refrigerant to return to the compressor, causing the compressor to be damaged by liquid shock

[0003] Since the window air conditioner is an integral air conditioner, a motor simultaneously drives the indoor wind wheel and the outdoor wind wheel to rotate for heat exchange, so the speed of the indoor wind wheel and the outdoor wind wheel are the same, so under low temperature refrigeration conditions, It is impossible to solve the above-mentioned problems in the low-temperature refrigeration process only by increasing or reducing the motor speed
