Title:
エコノマイザポートを通しての気液冷媒の注入
Document Type and Number:
Japanese Patent JP2005521854
Kind Code:
A
Abstract:
An improved apparatus and method for injecting a liquid/vapor into compression chambers at an intermediate pressure utilizes the economizer injection ports already found in the compressor. By selectively communicating a liquid to be injected into the compression chambers to the economizer return line, the economizer return line and its ports are utilized for this liquid/vapor injection. In this way, no additional flow connections at the compressor are necessary. Moreover, by injecting the liquid at an intermediate pressure point, the other benefits are provided. In general, the liquid is injected to reduce the discharge temperature of the refrigerant under certain operational conditions.
