A module for use in a cooling and heating system includes an enclosure having a number of cartridge-receiving slots and at least one cartridge interchangeably disposed in one of the slots. The cartridge contains components for producing chilled fluid. The system can include a refrigerated load that is supplied with chilled fluid from the cartridge and a heat sink to which the cartridge rejects heat. The cooling and heating system can be configured to have at least one refrigeration circuit charged with a refrigerant and including a compressor, a condenser, an expansion device, and a heat exchanger, and at least one secondary cooling circuit charged with a coolant and including the heat exchanger, and a cooling coil. Heat is transferred from the coolant to the refrigerant in the heat exchanger. The system further includes a heating circuit for transferring heat from the condenser to a heating load. |
