REFRIGERATION EFFICIENCY MONITORING SYSTEM

摘要

A refrigeration efficiency monitoring system detects degradation of a refrigeration system by monitoring a deviation from a normal operating status of the refrigeration system at an early stage of such degradation. The monitoring system detects and calculates a plurality of system parameters associated with the refrigeration system. The monitoring system then determines a decrease in efficiency of the refrigeration system based on comparison between the system parameters and reference values representative of the normal operating status, and generate a service recommendation based on the determination.

1. A method of maintaining a refrigeration system, the refrigeration system configured to control a temperature within a cabin, the method comprising:
arranging a first pressure sensor at a low pressure side of the refrigeration system; arranging a second pressure sensor at a high pressure side of the refrigeration system; running the refrigeration system for a preset period of time; obtaining a low side pressure at the low pressure side using the first pressure sensor; obtaining a high side pressure at the high pressure side using the second pressure sensor; obtaining a cabin air temperature using at least one temperature sensor; obtaining ambient temperature around the refrigeration system; determining a status of the refrigeration system by monitoring a deviation of at least one of the low side pressure, the high side pressure, the cabin air temperature, and the ambient temperature from at least one reference value, the at least one reference value representative of a normal operational status of the refrigeration system; and generating a service recommendation based on the status of the refrigeration system.
