In the cooling mode, chilled water absorbs heat via the coils and fan in the compart-ment’s air handling unit. The central unit consists of a compressor, two heat exchangers and a circulating pump. The central unit functions as a reverse cycle heat pump so it can provide either heating or cooling by simply reversing the flow of refrigerant ...

cooled condenser, and a chiller. The condenser and the chiller serve the same purpose as the condenser and the evaporator in a traditional refrigeration loop. Instead of exchanging heat with air, these heat exchangers exchange heat with circulating coolant and therefore act as sources of hot and cold coolant streams.
