Ground source heat pump

Ground source heat pump is the use of energy saving ground source heat pump systems, which use heat source flexible installation and easy control of tubes of a ground source heat pump system, also known as ground-coupled heat pump system tools. Body buried pipe by vertical way water as a heat carrier cooling water in the heat exchange tubes buried in the soil between the heat pump and circulation, and the ground crew to achieve the heat exchange between the soil. Ground source heat pump technology is the use of low temperature heat the surface of shallow water (groundwater, rivers, lakes, sea) of the soil to absorb solar energy and geothermal energy are formed, using heat pump principle, by a small amount of electrical energy output to achieve low heat A high heat transfer technology. Ground source heat pump to use new renewable energy source, energy conversion. Opened up a new way to use clean energy. Compared to conventional central air conditioning, the effect is more stable, by only a small amount of electrical energy output, it can achieve low energy to high energy conversion, a cleaner environment, and achieve cooling, floor heating and hot water supply, a machine performance stability and long life operation. Features ground (water) source heat pump technology, compared with conventional air conditioning has an unparalleled advantage. (1) the use of renewable energy: the case of renewable energy technologies ground source heat pump absorbs heat from ambient soil or surface water (ground water) or in its heat, the use of clean renewable energy, sustainable use. (2) energy efficient, low operating costs: the case of cost-effective energy-saving technologies ground source heat pump heat source temperature is relatively stable throughout the year, higher than the ambient air temperature in winter, lower in summer than the ambient air temperature, the temperature characteristics make ground source heat than conventional air conditioning system efficiency to 40%, thus saving energy and operating costs to be about 40%. In addition, the relatively constant temperature of geothermal energy, which makes the heat pump more reliable and stable, but also to ensure the system's efficiency and economy. When heating and cooling, 1KW input power can be more than 5KW refrigeration heating capacity. Operating costs per square meter per year is only 15--18 yuan, lower than conventional central air-conditioning system around 40%. (3) water-saving province: 1) soil (water) as a heat source, its heat release or absorb heat, do not consume water resources, will not cause pollution. 2) eliminating the boiler room and auxiliary coal yard, storage room, cooling towers and other facilities, room area is substantially smaller than a conventional air conditioning system, saving construction space, but also contributes to the beauty of the building. (4) the significant environmental benefits of the device is running without any pollution, can be built in a residential area, in the heat, no burning, no smoke, no waste, no stacking fuel waste sites, no city heat island effect, very friendly to the environment, is an ideal green environmental protection product. (5) the safe and stable operation, high reliability: ground source heat pump system in operation without combustion equipment, it is impossible to produce carbon dioxide, carbon monoxide and the like gas, propane gas does not exist, and therefore there will be no danger of explosion occurred, safe to use. Oil, gas boiler heating, combustion products, heavy pollution of the living environment, affect people's lives and health. Since the depths of the soil temperature is very constant, host an endothermic or exothermic from outside the climate, very stable operating conditions, is superior to other air-conditioning equipment. There is no lack of air-source heat pump heating, or even heating problems. Overall system maintenance costs of the boiler - greatly reducing the chiller system to ensure the system's efficiency and economy. Minimal amount of maintenance, depreciation and maintenance costs are also significantly lower than conventional air conditioning. (6) one machine, apply a wide range of ground source heat pump system for heating, cooling, a system that can replace the original boiler refrigerator plus two devices or systems. It can be used in hotels, shopping malls, office buildings, schools and other buildings, more suitable for residential heating and cooling. (7) In automatic operation of ground source heat pump due to the stable conditions, it is possible to design a simple system, fewer parts, simple and reliable plant operation and maintenance costs low; a high degree of automation, can be unattended; In addition, the unit long life, in more than 20 years.
