Comparison between air-cooled and water-cooled unitary air conditioners

Compares the advantages and disadvantages of air-cooled and water-cooled unitary air conditioners from different aspects including the unit EER, the overall nominal working condition refrigerating coefficient of performance, the area of machine room, and the influence on the building environment. Points out that to the areas in convention and exhibition buildings with temporary cooling/heating loads, there will be a better prospect for the decentralized air-cooled unitary air conditioners.
