この暖房能力不足を補うため、通常は電気と−タが用い
られているが、この方式では成績係数が悪くなる欠点が
ある。To compensate for this lack of heating capacity, electricity and heating are usually used, but this method has the disadvantage of having a poor coefficient of performance.
また、暖房能力を増大させる方式としてガスインジェク

ション流量に制限があシ、十分な暖房能力増加を実現で
きない欠点がある。Further, although a gas injection cycle is sometimes used as a method for increasing heating capacity, there is a limitation in the injection flow rate, and there is a drawback that a sufficient increase in heating capacity cannot be realized.
さらに、低沸点冷媒を混合した混合冷媒サイクルにより
暖房能力を増加させる方式も知られているが、蒸発温度

下する欠点がある。Furthermore, a method is known in which the heating capacity is increased by a mixed refrigerant cycle in which a low boiling point refrigerant is mixed, but this method has the disadvantage that the amount of heat absorbed from the outside air decreases due to the increase in evaporation temperature, resulting in a decrease in the coefficient of performance.

回路を設けたヒとを特徴とする。The purpose of the present invention is to solve the above-mentioned drawbacks and to achieve the purpose of heating, the present invention provides a compressor with two or more gas-liquid separators between the condenser and the evaporator. They are installed in series, and a pressure reducing device is installed on the inlet and outlet sides of each gas-liquid separator, and a circuit is installed to inject the cold and frequent gas separated by each gas-liquid separator into the middle of the pressure a stroke of the compressor.

21 solid gas-liquid separators installed in series between 6-8
9 and 10 are pressure reducing devices provided at the inlet and outlet sides of each gas-liquid separator 4.5, respectively, and 9 and 10 are injectors for injecting the refrigerant gas separated by each gas-liquid separator 4.5 during the compression stroke of the compressor 1. One refrigerant circuit 9 is designed to inject refrigerant gas to a high pressure position during the compression stroke of the compressor 1, and the other refrigerant circuit 10
The refrigerant gas is injected into a low pressure position during the compression stroke of the compressor 1.
次に本発明の作用について説明すると、圧縮機１から吐

する。Next, the operation of the present invention will be explained. After the high-pressure refrigerant gas discharged from the compressor 1 is liquefied in the condenser 2,
The pressure is first reduced in the pressure reducing device 6, and the gas flows into the gas-liquid separator 4 where it is separated into gas and liquid. The separated refrigerant liquid is subjected to secondary pressure reduction in the pressure reduction device 7 and then flows into the gas-liquid separator 5 to be separated into gas and liquid.The refrigerant liquid is further reduced in pressure in the pressure reduction device 8 and flows into the evaporator 3.

On the other hand, the refrigerant gas separated by each gas-liquid separator 4.5 is injected into the compressor 1 during its compression stroke via a refrigerant circuit 9.10.
このとき高圧側の気液分離器４で分離された冷媒ガスは
圧縮行程中の高い圧力位置に流入し、かつ低圧側の気液
分離器５で分離された冷媒ガスは圧縮行程中の低い圧力
位置に流入する。At this time, the refrigerant gas separated by the gas-liquid separator 4 on the high pressure side flows into a high pressure position during the compression stroke, and the refrigerant gas separated in the gas-liquid separator 5 on the low pressure side flows into the low pressure position during the compression stroke. Flow into position.

Since the injection flow rate increases, heating capacity can be significantly increased, and the coefficient of performance also improves.

７−向上する。Further, among the mixed refrigerant that has exited the condenser 2, refrigerant gas with a high concentration of high boiling point refrigerant is separated by each gas-liquid separator 4.5 and injected into the compressor 1 during the compression stroke. Since a refrigerant liquid with a high concentration of low boiling point refrigerant and low dryness flows into the evaporator 3, the amount of heat absorbed by the evaporator 3 increases.In the above embodiment, the gas-liquid separator is
Although an example is shown in which three or more are used, the effect will be further improved if three or more are used. By the way, on the Mollier diagram using R22 as the refrigerant, if there are 2 gas-liquid separators, 1
The heating capacity is approximately 1
4%, the coefficient of performance will increase by about 5tf6, and if the gas-liquid separator is 3 (@), the heating capacity will increase by about 20%, and the coefficient of performance will increase by about 7-.
以上説明したように、本発明によれば、暖房能力を増加
