Definitions

  • a pressure controlled water regulating valve 14 is located in the water supply pipe 12 to control the flow of water into the plate heat exchanger 10. Water leaving the heat exchanger via pipe 16 is fed to the drain.
  • the housing is 970 mm long, with a base 450 x 430 mm.
  • the legs can be 200mm in-depth to balance the height of the tri-wheels.
  • a housing of this size can accommodate the complete compression refrigerator, cooling fan 7 and electrical controls. It will be appreciated that the housing could be slightly bigger or a different size or shape provided it is mobile and freestanding.
  • a pressure feedback loop 52 controls the water regulation valve 14 so that water supply is cut off when the high pressure switch 40 is open indicating that the refrigeration system is not operating. Cutting off the water supply when the desired pre-set temperature has been reached in the chilled space, and the thermostat has cut out, prevents unnecessary waste of mains water.
