Cotton Insulation Tubular Heat Exchanger Double Circuit Air Conditioning System
Soil Heat Exchanger Ground Source Air Conditioning System.
This air conditioning system is the heat exchanger buried in the
ground, through the water in the high-
strength plastic pipe composed of closed loop circulation, in order
to achieve the purpose of hot and cold
with the earth soil exchange.
Summer through the unit will be the heat transfer to the ground,
the room for cooling. While storing heat
for winter use. In winter, the heat in the soil is transferred to
the room through the heat pump, and the
room is heated and stored for the summer.
The earth's soil provides a good free energy storage source, thus
realizing the seasonal transformation of
energy. Vertical Buried Ground Source Heat Pump System Horizontal

System
<1> Principle of Operation: Ground Source Heat pump air
conditioning is a "heat pump" (cooling, heating).
Heating, it absorbs geothermal discharge to the user, this process
consumes only a small amount of
power, as shown in Figure 1. Cooling, it absorbs the user's indoor
heat to the underground discharge,
also consumes a small amount of heat.
<2> unit operation process: the winter heat pump in the
positive flow of refrigerant, the compressor
discharge of high temperature and high pressure R22 gas into the
condensation To the water in the water
collector to release heat, the phase change to high temperature and
high pressure of the liquid, and then
by the thermal expansion valve throttle pressure into low
temperature and low pressure liquid into the
evaporator, from the underground circulating fluid to absorb low
temperature heat phase change Low
temperature and low pressure saturated steam into the compressor
suction side, compressed by the
compressor to discharge high temperature and high pressure gas to
complete a cycle. So the cycle of
underground low-temperature heat "handling" to the sump, which
continue to provide users with 45 ℃ -50
℃ hot water.
3. Summer heat pump in the reverse flow of refrigerant, and the
user heat exchanger into the evaporator
from the collector in the low-temperature water (7-12 ℃) to extract
heat, and underground heat exchanger
evaporator into the condenser to the Underground circulation liquid
discharge heat, circulating fluid heat
and then to the underground low-temperature area emissions, so the
cycle to continue to provide users
with 7-12 ℃ cold water.
