What does ground source air conditioning mean? Ground source air conditioning working principle
Although the ground source air conditioner is a rising star in the air conditioner market, the ground source air conditioner is an energy-saving and environmentally-friendly product integrating central air conditioner, home heating and water heater. It is deeply loved by consumers. What does the source air conditioner mean? What is the principle? The following decoration home decoration network Xiaobian will bring you the working principle of ground source air conditioning, hoping to help everyone.
What does ground source air conditioning mean?
Ground source air conditioner is a ground source heat pump system that adopts energy saving and environmental protection. Its cold and heat source adopts a buried tube type soil source heat pump system which is flexible and easy to control, also called soil coupled heat pump system. Specifically, the buried buried pipe method is adopted, and water is used as a cold heat carrier, and water is circulated between the heat pump pipes buried in the soil and the heat pump unit to realize heat exchange between the unit and the soil of the earth.
Ground source air conditioning working principle:
The fundamental principle of ground source air conditioner is to make full use of the reusable energy in nature. The ground source air conditioner is not only energy-saving but also environmentally friendly. As a high-tech project, ground source air conditioners have higher requirements on the site and the installation cost is not low. Due to the limitations of these two aspects, the ground source air conditioner has not been widely promoted. At present, only high-end villas or large shopping malls are installed with ground source air conditioners, but over time, the advantages of ground source air conditioners will become more and more obvious. Although the previous investment is higher, it can save more expenses considering its service life and energy saving effect.
1. Principle of temperature control: In general, ground source air conditioners are temperature-controlled by adhering to the shallow soil and groundwater in the surface. In the summer, the heat in the building is underground, while in winter, the soil and groundwater are accumulated. The amount of solar energy extracted is extracted to perform indoor heating to solve the problem of temperature regulation.
2. Refrigeration principle: In the hot summer, the ground source air conditioner realizes the heat transfer from the indoor to the underground, that is, the heat is discharged to the underground circulation heat, and the heat in the circulating liquid is discharged to the underground low temperature, and simultaneously to the user indoors. Provide cold water.
3, heating principle: the indoor cold water flows to the ground, through the compressor is the underground cold water into a high temperature and high pressure liquid, and then the compressor emits high temperature gas, transported to the interior, to achieve a cycle, can provide users 45 degrees Celsius Hot water to 50 degrees Celsius.
How about ground source air conditioning?
1. Renewable energy: It is a renewable energy utilization technology. Ground-source heat pumps absorb or remove heat from normal-temperature soil or surface water (groundwater), using renewable clean energy for sustainable use.
2, high efficiency and energy saving, low operating costs: is a cost-effective energy-saving technology. The temperature of the cold source of the ground source heat pump is relatively stable all year round, the temperature is higher than the ambient air in winter, and the temperature is lower than the ambient air in summer. This temperature characteristic makes the ground source heat pump 40% more efficient than the traditional air conditioning system , so it is necessary to save energy. And save operating costs by about 40%. In addition, the relatively constant temperature of the ground energy makes the operation of the heat pump unit more reliable and stable, and also ensures the high efficiency and economy of the system. In the case of heating and cooling, the input of 1 kW of electricity can obtain more than 5 kW of cooling and heating. The operating cost is only 15-18 yuan per square meter per year, which is about 40% lower than the conventional central air conditioning system.
3, water-saving and land: the soil (water) as a source of cold heat, to release heat or absorb heat, does not consume water, will not cause pollution. The boiler room and the auxiliary coal yard, oil storage room, cooling tower and other facilities are omitted. The area of ​​the machine room is much smaller than the conventional air conditioning system, which saves the building space and is also conducive to the aesthetic appearance of the building.
4. Significant environmental benefits: The plant operates without any pollution and can be built in residential areas. When heating, there is no burning, no smoke, no waste, no need to stack fuel waste, no city will be produced. The heat island effect is very friendly to the environment and is an ideal green product.
5. Safe and stable operation, high reliability: The ground source air conditioner has no combustion equipment during operation, so it is impossible to generate exhaust gas such as carbon dioxide and carbon monoxide, and there is no propane gas, so there is no danger of explosion. . Fuel and gas boiler heating, its combustion products are extremely polluting to the living environment, affecting people's lives and health. Due to the very constant temperature in the deep soil, the host heat absorption or heat release is not affected by the external weather, and the operating conditions are very stable, which is superior to other air conditioning equipment. There is no problem that the air source heat pump does not provide enough heat or even heat. The maintenance cost of the entire system is also greatly reduced compared to the boiler-refrigerator system, ensuring the efficiency and economy of the system. The amount of maintenance is minimal, and the depreciation and maintenance costs are also significantly lower than traditional air conditioners.
6, a machine dual-use, a wide range of applications: ground source air conditioning can be heating, cooling, a system can replace the original two sets of equipment plus boiler plus refrigerator. It can be applied to hotels, shopping malls, office buildings, schools and other buildings, and is more suitable for heating and cooling of residential buildings.
7. Automatic operation: Due to stable working conditions, ground source air conditioners can be designed with simple systems, fewer components, simple and reliable unit operation, low maintenance costs, high degree of automatic control, and unattended operation. In addition, the unit has a long service life. In 20 years or more.
The above is what Xiaobian brings to you. What does the ground source air conditioner mean?
