摘　　要：与常规空调系统相比,由于冰蓄冷低温送风系统的送风量减小,可节省风管投资,减少风机轴功率。计算可知,当低温送风的风量减少一半时,低温送风与常规送风管路的保冷投资基本相当。而低温风管尺寸减少约50%,节省风管投资约30%,风机轴功率减少约48%。因此,低温送风空调输配系统,是一种经济的供冷输配方式。Compared with conventional air conditioning system, cold air distribution system with ice storage can decrease investment and save energy as air volume reduces. We know as calcntions, when reducing by half in air volume of cold air distribution system, the investment of cool insulating thickness of cold air distribution duct is equal to the conventional air conditioning system nearly, but when the air duct size reduces by about 50%, it saves the air ducts investment about 30%, the power of fan can reduce about 48%. Therefore cold air distribution system is an economical cooling way.
