Initial investment, operating cost and application scope of air conditioning systems such as ground source heat pump, air-cooled heat pump and VRV. Has anyone summed it up? A preliminary estimate will do. Compared with air-cooled main engine and VRV, ground source main engine has the lowest price and the highest energy efficiency ratio, but it is greatly limited by objective conditions, such as the high cost of drilling wells in underground pipeline system and the large water demand in groundwater system, which limits its popularization and use.

Air-cooled heat pump does not need a special computer room. The price of air-cooled scroll main engine is generally 0.6-0.8 yuan/kcal, and that of air-cooled screw is about 1. 10 yuan/kcal, with an energy efficiency ratio of 3-3.5.

VRV system has the highest cost, but its application is flexible, and its energy efficiency ratio is similar to that of air-cooled heat pump. Due to the limitation of nozzle length, it is suitable for small-area projects.
