The flow control valve, the liquid level sent for receiving the liquid level sensor 14, and adjust the refrigeration
The flow of 1 inner refrigerant liquid of agent inlet pipe, so that the liquid level that the liquid level sensor 14 is sent maintains default normal number
It is worth section.For example, being greater than the maximum value in default regime values section, then the 1 inner refrigerant liquid of refrigerant inlet pipe is turned down
Flow, if tuning up the stream of the 1 inner refrigerant liquid of refrigerant inlet pipe lower than the minimum value in default regime values section
Amount.
Therefore, the present invention adjusts flow by flow control valve, can make during feed flow, guarantees in liquid separation chamber 6
Liquid level in a reasonable range.
In the present invention, in order to according to the pressure of gas in liquid separation chamber 6, to correspond to control to the work shape of battery coil 7
State (is powered or powers off), to discharge the gas refrigerant in liquid separation chamber 6 in time, gas occurs to be effectively relieved in evaporator
