[0003] Because the electric heating belt is in a heated state for a long time, it consumes a lot of electricity
However, in order for the air conditioner to start normally, it must be heated. Therefore, in order to avoid the waste of electricity, some manufacturers currently use the electric heating belt to turn on the heating belt tens of minutes before the heating operation, but it brings a lot of trouble to the user. Inconvenient, therefore, most manufacturers still use the way of standby for long-term heating

Embodiment Construction
[0018] The present invention will be described in detail below with reference to the accompanying drawings.
[0019] like figure 1 As shown, the present invention discloses a standby electric heating control device for an air conditioner, which includes a control system and a first temperature sensor connected to the control system for sensing the temperature of the outdoor unit heat exchanger, that is, the outdoor ambient temperature, a For the second temperature sensor that senses the temperature at the bottom of the compressor and the heating device that heats the bottom of the compressor, the control system controls the working state of the heating device according to the signal comparison result of the first temperature sensor and the second temperature sensor. In this embodiment, the heating device is an electric heating belt.
[0020] This device is only heated when the compressor needs to be heated, which greatly shortens the heating time of the compressor heating dev...

The invention belongs to the air conditioner technical field and discloses a standby electric heating control device and method of an air conditioner, aiming to solve the problem that the existing compressor is not convenient to heat and also solve the energy consumption problem. The control device comprises a control system, a first temperature sensor used for sensing the temperature of the heatexchanger of an outdoor unit, a second temperature sensor used for sensing the bottom temperature of the compressor and a heating device used for heating the bottom of the compressor, wherein the first temperature sensor, the second temperature sensor and the heating device are connected with the control system, and the control system controls the work condition of the heating device according tothe signal comparison result of the first temperature sensor and the second temperature sensor. The invention greatly shortens the heating time of the heating device of the compressor and effectivelysaves the energy.
Description
technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a standby electric heating control device and method for an air conditioner. Background technique [0002] When the outdoor temperature of the air conditioner is lower than -10°C for heating operation, because the outdoor temperature is too low, there is too much liquid refrigerant remaining in the compressor, so that the compressor cannot be started due to liquid shock when it starts. Therefore, the current air conditioners used in low temperature environments are usually equipped with electric heating belts of several tens of watts at the bottom of the compressor. In the standby state, the electric heating belts are always in the heating state, and the compressor can work normally when the compressor is turned on. Start running. [0003] Since the electric heating belt is in a state of heating for a long time, a large amount of electricity is consumed. Ho...
