Problems solved by technology

Therefore, the whole structure becomes complicated, the manufacturing cost increases, and it is difficult to install the float on the guide rod
[0013] Also, in the case of high pressure type floats, the float itself will deform due to the pressure of the injected air

Abstract

An apparatus for controlling a refrigerant level comprises a first detecting unit installed at a lower side of the inside of a refrigerant tank, for detecting whether a refrigerant stored at a lower side of the inside of the refrigerant is a liquefied refrigerant or a gaseous refrigerant, a second detecting unit installed at an upper side of the inside of the refrigerant tank, for detecting whether a refrigerant stored at an upper side of the inside of the refrigerant tank is a liquefied refrigerant and a gaseous refrigerant, and a control unit controlling intake and discharge of the liquefiedrefrigerant according to a value measured by the first detecting unit and the second detecting unit.

Description

technical field [0001] The invention relates to a device for controlling the liquid level of refrigerant, in particular to a device for controlling the liquid level of refrigerant stored in a refrigerant tank. Background technique [0002] figure 1 It is a longitudinal sectional view of a refrigerant tank with a conventional device for controlling the refrigerant liquid level. [0003] Such as figure 1 As shown, a refrigerant tank 10 provided with a conventional means for controlling a refrigerant liquid level has a space portion 12 for storing refrigerant in a main body 11 . [0004] A suction pipe 13 for receiving liquid refrigerant 12 a is formed at an upper portion of the main body 11 of the refrigerant tank 10 , and a discharge pipe 14 for discharging liquid refrigerant 12 a is formed at a lower portion of the main body 11 of the refrigerant tank 10 . [0005] On the suction pipe 13 is installed a suction valve 13 a for controlling the entry of refrigerant into the m...
