Background technology
Existing Gas-supplying enthalpy-increasing air conditioner, it is typically all using flash vessel as economizer.Existing flash vessel includes shell
Body, refrigerant feed tube, refrigerant drain pipe and escape pipe, and the gas supplementing opening of escape pipe connection compressor carries out tonifying Qi.In air conditioner
During normal heating operation, liquid refrigerant becomes gas-liquid two-phase state and entered by refrigerant feed tube after electric expansion valve throttles
Enter flash vessel, in flash vessel, liquid refrigerant enters another electric expansion valve by refrigerant drain pipe, and throttling is laggard to enter the room
External condenser exchanges heat；Gas refrigerant enters the gas supplementing opening of compressor by escape pipe.And in the running of reality, two
The aperture of electric expansion valve changes the change that can influence liquid level in flash vessel.If there is no liquid in flash vessel, gone out by refrigerant
The refrigerant amount that liquid pipe enters condenser is seldom, causes heating effect poor；If liquid is excessive in flash vessel, big quantity of fluid passes through
Escape pipe enters the gas supplementing opening of compressor, causes gas supplementing opening largely to return liquid, and systematic function declines to be made to the security of press simultaneously
Into extreme influence.Therefore suitable liquid level is extremely important to the systematic function and safety in flash vessel.
Therefore, using existing flash vessel, its drawback is that the liquid level in flash vessel can not be monitored effectively, when
In flash vessel during full liquid, it will there is big quantity of fluid moment to enter compressor gas supplementing opening, it is difficult steady for so may result in air compensating system
Fixed control, while the life-span of compressor assembly can be influenceed.
The content of the invention
In order to solve the above problems, the invention provides the control of a kind of flash vessel, air-conditioner system and air-conditioner system
Method processed, the invention pass through compressor by setting multiple times liquid units on escape pipe, to the liquid level in flash vessel
Temperature obtains effective monitoring, to keep the liquid level in flash vessel in safe range, so that air-conditioner system is steadily transported
OK, the life-span of compressor assembly is extended.
In order to achieve the above object, the technical solution adopted by the present invention is：
