The refrigerant of the machine radiator temperature corresponding when meeting tonifying Qi temperature requirement；
Control method of the present invention is to increase the thermic load of refrigerant using the waste heat of electric control element, and flow back to refrigerant after heat exchange
Compressor carries out Gas-supplying enthalpy-increasing, therefore while adjusting first throttling device to control refrigerant tonifying Qi temperature, should also make to radiate
Device temperature reaches corresponding tonifying Qi temperature condition, can sufficiently be exchanged heat, be supplemented with electric control element with flowing through the refrigerant of radiator
The thermic load of refrigerant.
Outdoor temperature, outdoor unit temperature and radiator temperature when S102, detection operation of air conditioner heating mode；
In embodiment, outdoor temperature detects to obtain by being set to the first sensor on the outside of outdoor unit, outdoor unit temperature
It detects to obtain by being set to the second sensor inside outdoor unit, radiator temperature is by being set to the of heatsink fins on piece
Four sensors detect to obtain.Wherein, it will have a direct impact on its changing with outdoor environment due to coagulating frost on outdoor unit First Heat Exchanger
The thermal efficiency, therefore second sensor is set to the position of neighbouring First Heat Exchanger inside outdoor unit, and second sensor is surveyed
The temperature of the First Heat Exchanger obtained is as the parameter for judging whether to reach solidifying white critical-temperature in subsequent step；
S103, it is not more than outdoor temperature threshold value in outdoor temperature, and when outdoor unit temperature is no more than solidifying white critical-temperature, with
Reference opening amount of the corresponding aperture of maximum stream flow as first throttling device, adjusts the aperture of first throttling device, so that heat dissipation
Device temperature meets tonifying Qi temperature condition.
In embodiment, the present invention is using solidifying white critical-temperature as the ginseng for sentencing measurement compressor and whether needing Gas-supplying enthalpy-increasing
Number, in operation of air conditioner heating mode, the First Heat Exchanger of outdoor unit exchanges heat with its surrounding air, in First Heat Exchanger
Refrigerant heat absorption evaporation, causes the temperature of its surrounding air to reduce, and outdoor unit still will appear solidifying frost problem, thus outdoor temperature not
When greater than outdoor temperature threshold value, it is still necessary to judge whether outdoor unit temperature is greater than solidifying white critical-temperature；
In embodiment, when outdoor unit temperature is no more than solidifying white critical-temperature, outdoor unit meets solidifying ice-lolly part, outdoor unit
First Heat Exchanger surface starts solidifying frost occur, in order to keep the heat exchange efficiency of First Heat Exchanger, it is therefore desirable to carry out to compressor
Gas-supplying enthalpy-increasing operation is opened by control first throttling device in step s 103, flows refrigerant along cooling line, utilized
The waste heat of electric control element heats refrigerant, and refrigerant is enable to reach the refrigerant conditions dictate of Gas-supplying enthalpy-increasing.
In the above process, the aperture of first throttling device is improved from initial opening to the corresponding aperture of maximum stream flow or
First throttling device is controlled to open with the corresponding aperture of maximum stream flow, to improve the refrigerant entirety flow in cooling line, thus
Increase the heat exchange amount of refrigerant and electric control element, and then refrigerant is made to meet the refrigerant conditions dictate of Gas-supplying enthalpy-increasing；Simultaneously as automatically controlled
The temperature of element and radiator is also influenced by outdoor environment, in the process of control method of the present invention, is based on maximum stream flow pair
The aperture answered carries out Secondary Control to first throttling device, so that the heat transfer process of radiator and electric control element can continue
It carries out.
In some embodiments, the step of tonifying Qi temperature condition is obtained in the present invention includes: to determine and mend according to outdoor temperature
