Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2007/034744
Kind Code:
A1
Abstract:
An air conditioner comprising a super-cooling heat exchanger for exchanging heat
between high pressure refrigerant and low pressure refrigerant, wherein the
super-cooling heat exchanger is installed in an indoor unit and has a structure compatible
with an evaporator so that the evaporator is made as small and compact as possible
while the heat exchange performance of the heat exchanger is enhanced without
enlarging its volume. The super-cooling heat exchanger has such a structure that
a high-pressure liquid refrigerant pipe is wound around the outer circumference of
a low-pressure refrigerant suction pipe and can be installed in the indoor unit.
The super-cooling heat exchanger having such a structure that the high-pressure liquid
refrigerant pipe is wound around the outer circumference of the low-pressure refrigerant
suction pipe is located below an indoor unit-side evaporator and drain water
from the evaporator is sprayed onto the super-cooling heat exchanger or drain
piping from the drain pan of an evaporator in the indoor unit is wound around the
outer circumference of the low-pressure refrigerant suction pipe of the super-cooling
heat exchanger together with the high-pressure liquid refrigerant pipe so that
cold heat of drain water acts effectively on the high-pressure liquid refrigerant
pipe to exchange heat, thus enhancing heat exchange efficiency for super cooling
as much as possible.
