在日本中央空调市场上,风冷式制冷冷水机组和热泵冷水机组占据了冷水机组近一半的份额。通常,日本市场上的风冷式冷水机组的制冷(热)量为120 hp及以下。这是因为高压气体法规对制冷(热)量120 hp以上的设备有特殊的安装要求。因此,制冷(热)量40~120 hp之间,使用60 hp以上的螺杆压缩机的冷水机组成为市场主流产品。主流制冷剂为R134a,但是,与整体式空气调节机相同,制冷(热)量在30 hp及以下的小型冷水机组主要使用R410A。约10年前,40~120 hp的风冷式冷水机组刚
In Japan’s central air-conditioning market, air-cooled chillers and heat pump chillers account for nearly half of the chiller unit’s share. In general, the air-cooled chiller unit in Japan has a cooling (heating) amount of 120 hp or less. This is because high-pressure gas regulations have special installation requirements for equipment with a cooling (heating) level above 120 hp. Therefore, the cooling (heat) amount of 40 ~ 120 hp, the use of more than 60 hp screw compressor chiller into the market mainstream products. The mainstream refrigerant is R134a, however, as in the case of integral type air conditioners, R410A is mainly used in small chillers with a cooling (heat) amount of 30 hp or less. About 10 years ago, 40 ~ 120 hp air-cooled chiller just
