Hotel hot water choice, air source heat pump or ground source heat pump?

Conditions permit (there is enough open space between hotel buildings to make holes), of course, it is to choose ground source heat pump. Its return on investment is high and its work is more reliable and stable. The advantages of air source heat pump are low one-time investment, simple installation and no need for computer room and air duct installation. Because the air source heat pump works according to the temperature difference in the air, its refrigeration and heating coefficients decrease with the decrease (winter) or increase (summer) of outdoor temperature. Ground source heat pump uses the earth as energy storage medium, which can transfer heat to the ground in summer and store it, and then take it out in winter. Therefore, the energy utilization efficiency of ground source heat pump is at least 40% higher than that of air source heat pump. At present, Sweden's ground source heat pump system has the highest energy efficiency, which can reach 70%.

At present, the quality of air source heat pump in China is very reliable, but the host of ground source heat pump is still unstable. Therefore, the conclusion of your question is: if you choose ground source heat pump for hotels, you'd better choose imported host, otherwise you will choose air source heat pump.
