Abstract
Refrigeration systems are described. The systems include a refrigeration circuit having a compression device, a heat rejecting heat exchanger, an expansion device, and a heat absorbing heat exchanger. The refrigeration systems include one or more sensors configured to measure a pressure associated with the heat rejecting heat exchanger, and a controller configured to compare the pressure measured by the one or more sensors to a predicted pressure, and to control the expansion device on the basis of the comparison.
Claims19
A refrigeration system comprising:
- a refrigeration circuit comprising a compression device, a heat rejecting heat exchanger, an expansion device, and a heat absorbing heat exchanger;
- one or more sensors configured to measure a pressure associated with the heat rejecting heat exchanger;
- and
- a controller configured to compare the pressure measured by the one or more sensors to a predicted pressure, and to control the expansion device on the basis of the comparison.
A method of operating a refrigeration system that comprises a refrigeration circuit comprising a compression device, a heat rejecting heat exchanger, an expansion device, and a heat absorbing heat exchanger, the method comprising:
- measuring a pressure associated with the heat rejecting heat exchanger;
- comparing the measured pressure to a predicted pressure;
- and
- controlling the expansion device on the basis of the comparison.
