| 摘要 |
The present invention relates to a method and a system for cooling a piston-driven compressor to permit the compressor to operate with a refrigerant gas, such as freon 22, that would normally cause the compressor to overheat and eventually break down. The method and system comprises connecting a heat exchanger in the cool side of the refrigeration system and connecting it in heat exchange relationship with oil circulated in the compressor to cool the oil to lower the compressor temperature whereby the compressor may operate effectively with the refrigerant gas without overheating. |
