Abstract

The present invention provides a method and a system for operating a refrigeration unit. The method and the system include the steps of: measuring a first characteristic of a refrigeration unit, calculating a compressor middle stage pressure based on the first measured characteristic, determining if a first comparison and a second comparison are satisfied based on the first measured characteristicand the calculated compressor middle stage pressure, and opening an economizer solenoid valve when the first comparison and the second comparison are satisfied.

Description

Background technique [0001] The subject matter disclosed herein relates generally to refrigeration systems, and more specifically, to energy efficient appliance controls for refrigeration systems. [0002] A particular difficulty with transporting perishable items is that such items must be maintained within a certain temperature range, depending on the item, in order to reduce or prevent the item from spoiling or otherwise being damaged by freezing. Transport refrigeration units are used to maintain proper temperatures in spaces where cargo is transported. The transport refrigeration unit can operate under the control of the controller. The controller ensures that the transport refrigeration unit maintains a specific environment (eg, a thermal environment) within the space in which goods are transported. Contents of the invention [0003] According to one embodiment, a method of operating a refrigeration unit is provided. The method includes measuring a first characteris...
