Title:
REFRIGERATION CYCLE AND COMPRESSION ASSISTANCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/029493
Kind Code:
A1
Abstract:
Power of a compressor in a refrigeration cycle is reduced to save energy. In the refrigeration
cycle, drive force for rotating a pump (22) is generated in an accumulator (6)
by rotating a turbine (21) by refrigerant sent from a gas cooler (2), and refrigerant introduced
from an evaporator (4) is compressed by the pump (22). As a consequence, the pressure
of the refrigerant sent toward the compressor (1) by rotation of the pump (22)
is increased, that is, suction pressure of the compressor (1) is increased, with
the result that power of compressor (1) in a refrigeration cycle is reduced to
save energy.
