The difference between ground source heat pump and air source heat pump

Ground source heat pump and air source heat pump are used advanced heat pump technology, they have one thing in common, are energy porters, but they are very different in energy conversion, ground source heat pump using existing geothermal resources , While the air source heat pump through the air source heat pump technology to energy conversion, through the ground source heat pump air conditioning and air source heat pump air conditioning we can see the pros and cons of the two where. 

What is the difference between ground source heat pump and air source heat pump? Air source heat pump air conditioner to do twice work In order to obtain the comfort temperature we need, we use heat pumps to heat and cool the outdoor air, and the processed to meet our desired comfort temperature to the interior, which is air source heat pump air conditioning The principle and process of work. We know that the energy of the air source heat pump comes from outdoor air. The heat pump unit is greatly affected by the environment during the operation. The outdoor temperature in winter is less than the comfortable temperature required by human beings. In summer, the outdoor temperature is higher than the comfort temperature we need. In this process, the heat pump consumes electric energy as a "two power", one is to work on outdoor air, so that the outdoor air temperature is increased or decreased; the other is to carry out work, in order to move cold and heat into the room . Ground source heat pump air conditioning only once Gong is the largest solar energy carrier, the surface below -6 meters of soil and groundwater temperature at 10 ~ 18 ℃ constant. Ground source heat pump through the heat exchanger and carrier, consume a small part of the power to work, the energy contained in the temperature of 10 ~ 18 ℃ by heat pump unit delivered to the interior, in the winter play a heating effect; summer to indoor Heat through the heat pump unit delivered to the ground, play a cooling effect, which is ground source heat pump air conditioning work principle and process. In this process, the heat pump consumes only the "one power" energy, that is, handling, which is why the ground source heat pump air conditioner is more energy efficient than the air source heat pump air conditioner. Ground source heat pump air-conditioning and air-source heat pump air conditioning energy-saving 40-60%. Air source heat pump air conditioners subject to natural conditions air source heat pump air conditioning in the summer outdoor temperature is very high, it is difficult to indoor hot air to the outside, the room cooling effect is poor; winter outdoor temperature is low, the heating will have knot Frost phenomenon, heating effect is also poor. 

People on the air source heat pump air conditioning has an image analogy: "summer is not cooling, winter does not heat." Ground source heat pump air conditioners are not subject to natural conditions Ground source heat pump air conditioners are completely unaffected by the ambient temperature, stable conditions, and ground source heat pump will not cause environmental pollution, urban heat island effect, is one of the most energy-efficient "three-use" heat pump air conditioning unit. Ground source heat pump air conditioning is the most energy-efficient air-conditioning system, many European and American countries have already begun to vigorously promote, and even promulgated the relevant laws and regulations clearly enforced. Ground source heat pump in China has also received great attention as a national key recommendation project. At present, ground source heat pump in many first and second tier cities in our country began to focus on pilot projects. In addition, home villa users began to base their efforts on using ground source heat pump air conditioners in the long run.
