Problems solved by technology

Therefore, there is also the risk of damaging the compressor
In addition, since the space in the gas-liquid separator 10 becomes smaller, the performance of gas-liquid separation decreases, and there is also a problem that the gaseous refrigerant G flows out from the liquid outlet 10b.

Embodiment Construction

[0037] Hereinafter, embodiments of the present invention will be described with reference to the drawings. For the convenience of description, the same parts as those in the conventional example shown in the above-mentioned FIGS. 4 and 5 are denoted by the same symbols. FIG. 1 is a circuit diagram showing a refrigeration cycle mechanism according to a first embodiment. The refrigeration cycle mechanism 1 is used for a refrigerator or an air conditioner including a freezer.

[0038] The refrigeration cycle mechanism 1 includes a compressor 2 , a condenser 3 , an expander 4 , and an evaporator 5 through which a refrigerant flows sequentially. Compressor 2 compresses refrigerant. The condenser 3 condenses the refrigerant compressed by the compressor 2 . The refrigerant condensed by the condenser 3 is expanded in the expander 4 . The evaporator 5 evaporates the refrigerant expanded by the expander 4 .

[0039] An accumulator 6 is arranged between the evaporator 5 and the comp...

Abstract

The present invention provides a freezing circulate mechanism which can prevent the damage of the compressor and improve the freezing ability. The freezing circulate mechanism comprises a compressor (2) for compressing refrigerant; a condenser (3) for condensing the refrigerant compressed by the compressor; an expander (4) for expanding the refrigerant condensed by the condenser (3); a gas-liquid separator (10) which is used for separating the gas and liquid of the refrigerant from the expander and provided with a gas outlet (10c) for flowing out the gas refrigerant (G) and a liquid outlet (10b) for flowing out the liquid refrigerant (F); an evaporator (5) for evaporating the refrigerant flows from the liquid outlet; an accumulation device (6) arranged between the evaporator and the compressor for separating the gas and liquid of the refrigerant flows through the evaporator, and flowing out the separated gas refrigerant to the compressor, and accumulating the liquid refrigerant; and a gas bypass path (11) which is extending from the gas outlet and connected between the compressor and the accumulation device, and is provided with a liquid level control tubing leading-out from the gas-liquid separator and connected between the evaporator and the accumulation device.

Description

technical field [0001] The present invention relates to a refrigerating cycle mechanism (refrigerating cycle) in which a refrigerant circulates to release and absorb heat, and an air conditioner and a refrigerator using the same. Background technique [0002] Patent Document 1 discloses a conventional refrigeration cycle mechanism used in a refrigerator or an air conditioner. In the refrigeration cycle mechanism, the refrigerant passes through the compressor, the condenser, the expander, and the evaporator in sequence, the condenser releases heat, and the evaporator absorbs heat. Thus, the air conditioner can be used as a cooling and heating device, or a refrigerator (including a freezer) can be cooled and stored. [0003] A gas-liquid separator is arranged between the expander and the evaporator. Fig. 4 shows a longitudinal sectional view of the gas-liquid separator. The gas-liquid separator 10 is formed of a sealed bottomed cylindrical container, and the inlet 10 throug...
