Comparative analysis of ground source heat pump air conditioner and air source heat pump air conditioner

Both ground-source heat pumps and air-source heat pumps use advanced heat pump technology. They have one thing in common. They are both energy porters, but they have big differences in energy conversion. Ground-source heat pumps use existing ground energy resources. , While the air source heat pump uses air source heat pump technology to convert energy. Through the comparison of ground source heat pump air conditioners and air source heat pump air conditioners, we can see the advantages and disadvantages between the two.

　　 Air source heat pump air conditioner does work twice

　　 In order to obtain the comfortable temperature we need, we use a heat pump to heat up and cool the outdoor air, and carry the comfortable temperature that meets our needs after processing to the room. This is the working principle and process of air source heat pump air conditioning. We know that the energy of air source heat pump comes from outdoor air. The heat pump unit is greatly affected by the environment during operation. In winter, the outdoor temperature is lower than the comfortable temperature required by humans, and the outdoor temperature in summer is higher than the comfortable temperature required by humans. In this process, the heat pump consumes electric energy to perform "two work", one is to work on the outdoor air to increase or decrease the temperature of the outdoor air; the other is to carry work, in order to move the cold and heat into the room .

　　The ground source heat pump air conditioner only works once

　　The earth is the largest solar energy carrier. The temperature of soil and groundwater below the surface of the earth is 6 meters below the surface and the temperature is constant at 10～18℃ throughout the year. The ground-source heat pump consumes a small part of electric energy to do work through the heat exchanger and the carrier, and transports the energy contained in the temperature of 10～18℃ to the room through the heat pump unit, which plays a role of heating in winter; The heat is transported to the ground through the heat pump unit to play a cooling role. This is the working principle and process of ground source heat pump air conditioning. In this process, the heat pump consumes electric energy and only performs "one work", that is, transportation. This is the reason why ground source heat pump air conditioners are more energy-efficient than air source heat pump air conditioners. Compared with ground source heat pump air conditioners, ground source heat pump air conditioners can save energy by 40-60%.

　　 Air source heat pump air conditioner is restricted by natural conditions

When the outdoor environment temperature is high in summer, the air-source heat pump air conditioner is difficult to discharge the indoor hot air to the outside, and the cooling effect of the room is poor; when the outdoor environment temperature is very low in winter, the heating will be frosted, and the heating effect will be very good. difference. People have a vivid analogy for air source heat pump air conditioners: "No cooling in summer, no heating in winter."

　　 Ground source heat pump air conditioner is not restricted by natural conditions

　　The ground source heat pump air conditioner is completely unaffected by the ambient temperature, the working conditions are stable, and the ground source heat pump will not cause environmental pollution and urban heat island effect. It is the most energy-saving "three-purpose" heat pump air conditioner unit.

　　The ground source heat pump air conditioner is currently the most energy-efficient air conditioning system, so many European and American countries have already begun to vigorously promote it, and even promulgated relevant regulations for clear implementation. Ground source heat pumps have also received great attention in China and have become a national key recommendation project. At present, ground source heat pumps have begun to be piloted in many first- and second-tier cities in my country. In addition, family villa users have begun to use ground source heat pumps in the long run!
