Abstract
A method of controlling the performance of a refrigeration system includes operating first and second heat exchangers, the first to remove heat from one or both of a space where the first heat exchanger is disposed or a component within the space where the first heat exchanger is disposed. The first heat exchanger has a first set of parallel tubes between manifolds, the second heat exchanger has a second set of parallel tubes between manifolds the first and second tubes alternating in spaces between each other; Refrigerant that flows through the first set of tubes additionally flows through the second set of tubes before the refrigerant again flows through the first set of tubes. Operating a second heat exchanger that is fluidly connected with both of the first set of tubes and the second set of tubes. In situations where a build-up of frost occurs upon one or more surfaces of the first heat exchanger during operation, continuing to operate the first heat exchanger to transfer heat from the refrigerant to the first medium thereby performing a defrost function upon the one or more surfaces of first heat exchanger.
