Abstract

PURPOSE: To control the capacity of a chilling unit for controlling the number of operating units of standard product and finely control the water temperature thereof by providing a leased capacity control thermostat and a thermostat for a final operation chilling unit.
CONSTITUTION: There are arranged a sheated tank 5, a water tank 6, a circulating water pump 7 and fan coils 10. A leased capacity control thermostat 9 provided at the inlet tube 8 of chilling units 1W3 detects the water temperature to thereby control the number of operating chilling units by a controller 4. When the water temperature is high, the chilling units are stopped in the order of the units 3 and 2, and one cycle of the chilling unit 1, and two cycles of the chilling unit 1 are then stopped. When the water temperature rises, the chilling units are operated in the reverse order to the above. Thus, the chilling unit at the final stage can finely control the water temperature.
