从不同方面比较了风冷式和水冷式单元空调机组的优缺点,包括机组能效比、名义工况冷源综合制冷性能系数、机房面积以及对总体建筑环境的影响。指出了对于大型会展建筑中冷热负荷具有临时性的空调区域,分散式风冷单元空调机组有较好的发展前景。 The advantages and disadvantages of air-cooled and water-cooled unit air conditioning units are compared from different aspects, including unit energy efficiency ratio, coefficient of comprehensive cooling performance of nominal condition cold source, engine room area and the impact on the overall building environment. It is pointed out that the distributed air-cooled unit air-conditioning units have a good development prospect for the air-conditioned areas with temporary heat and cold load in the large exhibition and exhibition buildings.
