Embodiment Construction
[0008] The present invention will be further described below in conjunction with specific examples.
[0009] The air conditioner overheating protection control method described in this embodiment is to firstly place the temperature sensor probe connected to the indoor coil temperature detection module between the condenser indoor coils to transmit the real-time detected indoor coil temperature to the single chip microcomputer , and then the single-chip microcomputer judges according to the preset value; when the single-chip microcomputer judges that the temperature of the indoor coil is too high, the optimized overheating protection control scheme is started, and when the temperature sensor probe detects that the temperature of the indoor coil is too high for a long time, the air conditioner is temporarily shut down , no fault code is displayed, and after a few minutes, the air conditioner can automatically resume normal heating operation without powering on again. Among them,...

The invention provides an overheat protection control method and an overheat protection control device for an air conditioner. The overheat protection control method for the air conditioner comprises the following steps of: placing a temperature sensor probe which is connected with an indoor coil pipe temperature detection module between condenser indoor coil pipes to transmit the real-time detected temperature of the indoor coil pipes to a singlechip, and determining according to a preset value by using the singlechip; when the singlechip determines that the temperature of the indoor coil pipes is overhigh, starting an optimized overheat protection control scheme, and when the temperature sensor probe detects that the temperature of the indoor coil pipes is overhigh in a long term, temporarily stopping the air conditioner from operating, not displaying a fault code, and several minutes later, automatically recovering the heating operation of the air conditioner without re-electrification. By using the scheme, the overall performance of the air conditioner can be effectively improved, the energy efficiency of the air conditioner can be improved, and a market complaint rate can be lowered.
Description
technical field [0001] The invention relates to the technical field of household air conditioners, in particular to a control device for realizing an air conditioner overheat protection control method. Background technique [0002] The air conditioner operates in the heating mode, and the high-temperature and high-pressure refrigerant evaporates and dissipates heat indoors, heating the indoor air to achieve the heating effect of the air conditioner. During the heating operation of the air conditioner, due to the high temperature of the copper tube in the evaporator (also known as the indoor coil), the overheating protection is caused. 0.5 ~ 2mm), it is easy to cause dirty blockage and bias flow, which eventually causes the temperature of the overall copper pipe to rise; 2. The air conditioner operates during the peak period of electricity consumption, and the low voltage causes the indoor fan speed to be too low, and a large amount of heat in the evaporator cannot be blown n...
