As it is shown in figure 1, in the technical scheme of the present embodiment, air-conditioner also includes oil eliminator, oil eliminator is arranged between first end being exported to the first branch road 300 of compressor 10, and the isolated oil of oil eliminator is back to the entrance of compressor 10.Gs-oil separator be provided with the clarity beneficially keeping coolant.Specifically, the lubricating oil that oil eliminator is separated is back to the entrance of compressor 10, and said structure ensure that the lubrication of compressor 10, it is not necessary to again fills into lubricating oil to compressor 10 again, saves lubricating oil.
As it is shown in figure 1, in the technical scheme of the present embodiment, air-conditioner also includes gas-liquid separator, gas-liquid separator is disposed in the interior on the pipeline between the outlet of heat exchanger 30 and compressor 10 entrance.Carried out the gas-liquid separation of coolant by gas-liquid separator from the outlet of indoor heat exchanger 30 coolant out, the setting of said structure efficiently avoid the generation of the liquid hit phenomenon of compressor 10.
Present invention also provides the control method of a kind of air-conditioner, air-conditioner is above-mentioned air-conditioner, and the control method of air-conditioner includes: obtain the Current Temperatures of the indoor heat exchanger 30 of air-conditioner.
The Current Temperatures of the indoor heat exchanger 30 according to air-conditioner, it is judged that whether the first valve 40 of air-conditioner meets the condition opened.If the first valve 40 meets the condition opened, then open the first valve 40.
In the technical scheme of the present embodiment, according to the Current Temperatures of the indoor heat exchanger 30 of air-conditioner, it is judged that whether the first valve 40 of air-conditioner meets is opened condition and include:
One, when the Current Temperatures of indoor heat exchanger 30 is less than or equal to the first preset temperature, it is judged that the first valve 40 meets opens condition, then open the first valve 40.When compressor low-frequency operation, the first valve 40 is opened, and the first branch road 300 connects, and system high pressure raises, and low pressure raises, and indoor heat exchanger 30 is not easy frosting, will not frequently occur anti-freeze protection, and avoid the appearance of low-voltage variation.
Two, when the Current Temperatures of indoor heat exchanger 30 is more than the first preset temperature and is less than or equal to the second preset temperature, then Current Temperatures based on system high pressure side (Current Temperatures of system high pressure side refers to that compressor 10 is vented to the saturation temperature that the pressure of the pipeline between outdoor heat exchanger 20 is corresponding) judges whether the first valve 40 of air-conditioner meets the condition opened, it is divided into three kinds of situations, specific as follows:
1, when the Current Temperatures of system high pressure side is less than or equal to three preset temperatures, it is judged that the first valve 40 meets opens condition, then open the first valve 40, and the first branch road 300 connects.
2, when the 3rd preset temperature is less than or equal to four preset temperatures less than the Current Temperatures of system high pressure side, the first valve 40 maintains standing state, and the first branch road 300 maintains standing state.
3, when the 4th preset temperature is less than system high pressure side, the first valve 40 is closed, and the first branch road 300 disconnects.
Three, when the Current Temperatures of indoor heat exchanger 30 is more than the second preset temperature, it is judged that the first valve 40 is unsatisfactory for opening condition, then the first valve 40 is closed, and the first branch road 300 disconnects, now compressor output is big.
Preferably, when system high pressure is more than the second preset temperature, the second valve 50 is closed, and pressure-regulating valve 70 is opened, and the second branch road 400 connects, and plays release effect, protects compressor reliability service.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for a person skilled in the art, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
