Initial cost: In terms of main engine investment, the water-cooled chiller and the air-cooled chiller are less, but the cooling tower and the machine room/electronic water treatment device are actually not much different.

Intangible investment in the later stage: If it is operated for a long time, the cooling efficiency of the water-cooled chiller will decrease relatively, and the air-cooled chiller will not.

Ease of use: Air-cooled chillers use air cooling to eliminate the cooling towers, cooling water pumps and piping systems necessary for cooling water systems, to avoid condensation and water pipe blockage in areas with poor water quality, and to save Water resources are the most economical and simple models for maintenance and repair of cold water air conditioning equipment.

Maintenance cost: The air-cooled chiller has a slightly higher investment than the water-cooled chiller, but the annual operating cost is lower than that of the water-cooled chiller. The construction cost of the equipment room is the least in various air-conditioning cold and heat source systems, and the maintenance cost is about Half the cost for water-cooled or boilers. Air-cooled chillers are louder and cooler than water-cooled and can only be installed outdoors. Most of the water-cooled chillers are installed in the basement.
