Embodiment Construction

[0010] refer to figure 1 , provides an embodiment of the economizer assembly 100 of the present invention. The economizer assembly 100 has an external structure similar to that of conventional economizers, that is, a cylindrical shell 110 made of corrosion-resistant metal. The shell 110 is divided into two internal spaces by a partition 140 : an economizer chamber 120 and an interstage flow path chamber 130 . The casing 110 is provided with a condenser connection port 111 , an evaporator connection port 112 , a first connection port 113 and a second connection port 114 . Wherein, the condenser connection port 111 and the evaporator connection port 112 are in fluid communication with the economizer chamber 120 ; and the first connection port 113 and the second connection port 114 are in fluid communication with the interstage flow path chamber 130 . In addition, it should be known that, in order to realize the conventional air replenishment function of the economizer, the eco...

Abstract

The invention provides an economizer assembly, which includes: a housing; the housing is divided into an economizer chamber and an interstage flow path chamber by a partition; the economizer chamber is provided with a condenser connection port and an evaporator The interstage flow path chamber is provided with a first connection port and a second connection port connected between the multi-stage compressor units; the economizer chamber and the interstage flow path chamber are in the Fluid communication within the housing. The economizer assembly provided by the invention can simplify the pipeline complexity of the refrigeration system to which it is applied.

Description

technical field [0001] The present invention relates to refrigeration systems, and more particularly, the present invention relates to an improved economizer assembly for refrigeration systems. Background technique [0002] The economizer is a commonly used component in large-scale refrigeration systems, which is used to make a part of the refrigerant itself throttling, evaporating and absorbing heat, so as to subcool the other part of the refrigerant. In many cases it is used in refrigeration systems with multi-stage compressor trains. Under the condition of low evaporating temperature, ordinary multi-stage compressor units have many defects such as reduced efficiency, reduced cooling capacity and high exhaust temperature. If an economizer is used to replenish air between the compression stages of a multi-stage compressor unit, the efficiency of the refrigeration cycle can be improved, the cooling capacity can be increased, and the exhaust temperature of the compressor can...
