1. What is ground source heat pump system?
Ground source heat pump is a kind of high-efficiency and energy-saving air-conditioning system that uses the shallow earth resources (including soil and ground water, surface water, or urban reclaimed water) to supply hot water and also cooling. It uses heat exchange pipes laid in the soil and surface water to achieve heat exchange between air-condition rooms and soil and surface water to achieve the effect of building indoor air conditioning.
2. What is the energy saving effect of the heat pump central air conditioning system?
Ground-source heat pump central air conditioning is currently the most advanced central air conditioning system in the world. Its heating capacity-cooling capacity and the ratio of the electric power consumed are higher than 4.0 on average throughout the year, and it can get more than 4 kilowatts with 1 kilowatt of electricity. Compared with other heating methods, the heating energy consumption is reduced by 50%-70%, and the cooling energy consumption is reduced by 40%-60% compared with other cooling methods. The heat pump system will save you a lot of operating costs and maintenance. cost.
3. What is the energy saving principle of ground heat pump?
As the heat source of the ground source heat pump system (in winter) and the emission reduction source (in summer), the soil depth is below several meters, and the temperature is basically constant throughout the year. It is much higher than outdoor air temperature in winter and lower than air temperature in summer Therefore, the heat transfer conditions of ground-source heat pumps are far more concerned with air-source heat pumps, which require less external energy to realize the smooth transfer of heat energy.
4. How much space does the ground source heat pump need?
There are three types of heat pump units. One is a small unit. The cooling capacity of a single unit is not more than 25KW and can be installed in the ceiling without occupying any indoor space. The other is a large screw unit. The cooling capacity of a single unit is generally more than a few hundred kilowatts. It needs to be installed in a special room. Need to occupy a certain amount of indoor space. In general, the ground-source heat pump central air-conditioning unit covers an area of one-third that of traditional air-conditioning.
5. What is the life span of the ground source heat pump air conditioning system?
The life of the buried pipe heat exchange part is 50 years, and the heat pump unit has a lifespan of 25 years. The overall system has no outdoor unit, no wind, sun, rain, frequent cleaning, and its life is much longer than that of the outdoor unit and chiller of the air source heat pump. cooling system.
6. Is it really effective to bury closed loop pipelines underground?
Through the latest technological achievements in the development of underground pipe energy and heat technology, the theoretical concept of this technology was produced in the 1940s. In recent years, the innovation in heat pump technology design and the development of underground pipe technology have made the heat pump technology using geothermal energy reach commercial The best requirements for application. So far, ground source heat pump technology has become a traditional heating and cooling technology both economically and technically, and mature technology is applied in reality.
7. How does the ground source heat pump system achieve environmental protection?
The system does not directly consume coal and fuel oil, natural gas burners and other mineral materials. There is no direct emission of pollutants. Secondly, it transfers indoor heat to the underground soil for storage, eradicating the impact of the air conditioning system on the urban heat island from the source.
8. What are the specific manifestations?
(1) The ground source heat pump system does not directly consume coal or fuel oil, natural gas, etc., and there is no direct discharge;
(2) Ground source heat pump transfers indoor heat to underground soil for storage, eradicating the contribution of air conditioning system to urban heat island from the source;
(3) The highly efficient ground source heat pump system adopts a very strict control system, which realizes the direct correspondence between energy output and the energy demand of the building, and reduces the loss of remaining energy;
(4) The efficient ground source heat pump system outputs the same amount of useful energy and only consumes 30-60% of the electric power. The efficient primary energy utilization rate is the most direct reason for the environmental protection effect of the ground source heat pump system.
9. Under extremely low temperature climate conditions, should a spare heat source be required?
In the usual comfort air conditioning system, no backup heat source is needed; the temperature in the rock and soil layer below the surface of 5 meters remains basically unchanged throughout the year and is not affected by the atmospheric temperature, so the ground source heat pump system even in very cold weather conditions It can also provide the heat required by the building.,
