Technical principles of ground source heat pump: Ground source heat pump is a high-efficiency, environmentally friendly and energy-saving air conditioning unit that uses shallow geothermal resources in the ground to provide both heating and cooling. By inputting a small amount of high-quality energy (electromagnetic energy), a ground source heat pump can complete the transfer of energy from low-temperature heat sources to high-temperature heat sources. In winter, the heat generated in the soil is "taken out", and the temperature is raised to provide room heating; in summer, the heat generated in the house is "taken out" and released into the soil, and the underground temperature can be ensured for a long time. balance. Let Shandong ground source heat pump manufacturers take you through the advantages of ground source heat pumps.
Advantages of ground source heat pump:
1. Water source heat pump technology is a renewable resource utilization technology.
Water source heat pump is a heating and air conditioning unit that uses geothermal resources in the shallow part of the earth's atmosphere (generally less than 400 meters deep) as a cold and heat source to carry out heat transfer. The geothermal resources in the shallow part of the ground can be called Earth Energy, which refers to the ultra-low-temperature energy contained in the ground soil layer, surface water, rivers, and lakes that absorb solar power and geothermal energy. The shallow part of the ground is a large solar power source. The hot plate collects 47% of the solar energy, which is more than 500 times the energy used by people every year. It is not limited by region, resources, etc., is large in quantity, wide in range, and ubiquitous. This kind of energy is stored in shallow parts of the ground. Nearly endless renewable resources have prompted ground energy to become a way to clean up renewable resources.
2. Water source heat pump is an energy-saving and environmentally friendly method with reasonable economic development.
The temperature of ground energy or shallow geothermal resources is relatively stable throughout the year. It is higher than the ambient temperature in winter and lower than the ambient temperature in summer. It is an effective heat source for heat pumps and cold storage for air conditioners. This temperature characteristic makes water source heat pumps The operating efficiency is 40% higher than that of traditional air conditioning units, so it is environmentally friendly and energy-saving and saves about 40% of operating costs. In addition, the relatively stable temperature of ground energy makes the operation of water source heat pump units more reliable and stable, and also ensures the accuracy and rationality of the operating system.
According to the U.S. Environmental Protection Agency (EPA), designing and installing high-quality water source heat pumps can save users 30 to 40% of heating and cooling operating costs on average.
3. Water source heat pump has obvious ecological benefits
The pollution discharge of water source heat pumps is equivalent to a reduction of more than 40% compared with air source heat pumps, and is equivalent to a reduction of more than 70% compared with electric heating. If other environmental protection and energy-saving measures are combined, the energy saving and consumption reduction will be even more significant. Although refrigerant is also used, the filling volume is 25% lower than that of basic air conditioning equipment; it is a self-contained system, that is, the equipment can be installed in the workshop in advance with good sealing, so the probability of refrigerant leakage is greatly reduced. The operation of this equipment does not cause any environmental pollution, it can be built in residential areas, there is no ignition, no smoke exhaust system, no waste, no place to accumulate fuel waste, and no need to transport heat over long distances.
4. Water source heat pump is commonly used in one machine
The water source heat pump system has a wide range of applications for heating, air conditioning, and daily boiling water. One machine is commonly used, and one system can replace the previous sets of equipment or systems of heating furnaces and air conditioners; it can be used in hotels, large-scale Shopping malls, office buildings, schools and other engineering buildings are more suitable for heating and central air conditioning in single-family villas.
5. Water source heat pump air conditioning units have low maintenance costs
Under the same conditions, buildings using water source heat pump systems can reduce maintenance costs. The water source heat pump is very durable. It has very few molecular thermal motion components. All components are either buried underground or installed indoors, thereby protecting against outdoor weather. The underground part can be guaranteed for 50 years, and the above-ground part can be guaranteed. 30 years, so the water source heat pump is a maintenance-free central air conditioner, saving maintenance costs, so that consumers can get their investment back within 3 years.
In addition, the generator set has a long service life, more than 15 years; the generator set is compact and saves space; the automatic control system is high-level and can be unmanned.
