Abstract

The invention provides a middle pressing receiver, comprising a receiver mainbody which achieves the separation of gas and liquid inside the receiver, a first inlet / outlet pipe and a second inlet / outlet pipe which are arranged on the receiver mainbody and used for injecting a gas and liquid mixed refrigerant in any side and injecting out the liquid phase refrigerant which is separated from the gas and liquid mixture through the any other side, and a vapour outlet pipe used for injecting out the gas phase refrigerant which is separated from the gas and liquid mixture.

Description

[0001] This application is a divisional application of the patent application with application number: 200510076104.1, application date: June 8, 2005, and invention name "refrigerating device and intermediate pressure receiver". technical field [0002] The present invention relates to a refrigerating device which has an outdoor unit and a plurality of indoor units and can make a plurality of indoor units perform cooling operation or heating operation at the same time, or can perform a combination of these heating and cooling operations, and a gas-liquid transfer device used in the refrigerating device. Intermediate pressure receiver for gas-liquid separation of mixed refrigerants. Background technique [0003] In general, there is known a refrigeration system in which an outdoor unit and a plurality of indoor units are connected by inter-unit piping consisting of high-pressure gas pipes, low-pressure gas pipes, and liquid pipes, so that the plurality of indoor units can simu...
