Compressor assembly having electronics cooling system and method

摘要

A system, compressor, and method that cools an electronics module with a low-pressure refrigerant. The system, compressor, and method utilize a temperature sensor that detects a temperature of the low pressure refrigerant and communicates with the electronics module. Based on the temperature detected by the temperature sensor, the electronics module controls a liquid dry out point of the refrigerant that is used to cool the electronics module.

主权项

1. A system comprising:
a compressor having a suction side for receiving low-pressure refrigerant and a discharge side for dispensing high-pressure refrigerant; a pair of heat exchangers in communication with said compressor; an expansion valve disposed between said heat exchangers; a control module for controlling said expansion valve; an electronics module externally mounted to the compressor; a cooling apparatus mounted to the electronics module that receives said low-pressure refrigerant to cool said electronic module; a temperature sensor located at an inlet of said cooling apparatus, said temperature sensor for detecting a temperature of said low-pressure refrigerant entering said cooling apparatus, wherein said control module is in communication with said temperature sensor, and controls said expansion valve based on said temperature of said low-pressure refrigerant to minimize an amount of said low-pressure refrigerant in a liquid phase passing through said cooling apparatus.
