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 Buried Ground Source Heat Pump

<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.
