Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2007/034745
Kind Code:
A1
Abstract:
In the supercooling heat exchanger of an air conditioner for exchanging heat
between high pressure refrigerant and low pressure refrigerant, a flow direction
of refrigerant during a cooling operation is reversed during a heating operation
to cause the high pressure refrigerant and the low pressure refrigerant to flow
in parallel in either one operation mode, whereby a heat exchange efficiency
deteriorates. In an air conditioner comprising a supercooling heat exchanger
(13) for exchanging heat between low pressure refrigerant and high pressure
refrigerant, the supercooling heat exchanger (13) is divided into first and
second heat exchangers (13A, 13B), any one of the first heat exchanger (13A) and
the second heat exchanger (13B) is arranged such that the high pressure refrigerant
and the low pressure refrigerant produce counter flows, and the second heat exchanger
(13B) or the first heat exchanger (13A) on the other side is arranged such that
the high pressure refrigerant and the low pressure refrigerant produce parallel
flows. Each heat exchanger (13A, 13B) is arranged such that a high pressure liquid
refrigerant tube (15) is wound around the outer periphery of a suction tube (14)
for sucking low pressure refrigerant thus reducing each size.
