Abstract

PURPOSE: To increase a compression workload and improve effectively heating capacity, by opening to the full width a throttle valve disposed in an injection piping connected to a compression chamber of a compressor being compressed so as to pour high-pressure coolant gas into the compression chamber.
CONSTITUTION: In case of increasing heating capacity, operation is conducted after contracting adequately a throttle valv 13 disposed on the discharge side of a compressor 11 and opening to the full width a throttle valve 16 disposed on the way of an injection piping 15 connected to a compression chamber (not shown) of a compressor 11 being compressed. By opening the throttle valve 16 to its full width, high-pressure coolant gas is injected through the injection piping into the compression chamber of the compressor 11 and in a Mollier diagram illustrated, (f) point representing a gas state in a cylinder shifts to (g) point. Therefore, a compression workload in this case may be increased compared with the prior art and heat capacity may be improved effectively.
