Abstract
In an apparatus comprising: an evaporator 1 for boiling and evaporating a cold/heat evaporable liquid under a reduced pressure; a condenser 2 for condensing vapor; a cold/heat indirect heat exchanger 6 at a load 14 side; a cooling heat exchanger 11 using the air; cold-heat circulation means 5 and 7 for circulating a cold/heat evaporable liquid in the evaporator to the cold/heat indirect heat exchanger; cooling circulation means 10 and 12 for circulating a cooling evaporable liquid in the condenser to the cooling heat exchanger; and a vapor compressor 20 provided in a vapor duct 19 extending from the evaporator to the condenser, a running cost is reduced when a temperature at the condenser side becomes lower than a temperature at the evaporator side due to a drop in air temperature, without a rise in a temperature of the cold/heat evaporable liquid. The vapor duct 19 is provided with a bypass vapor path 22 for bypassing the vapor compressor. The bypass vapor path is provided with an on-off valve 23. When a temperature at the condenser side becomes lower than a temperature at the evaporator side, the vapor compressor is shut down and the on-off valve is opened.
