冷却系统的能源利用效率随所用冷却器的类型而变化。真空冷却器效率最高，其次是水冷却器、喷水真空冷却器和强制空气冷却器。非产品热输入水平和操作实践已被确定为差异的原因。同类型冷却器的能源利用效率差异显著。产品吞吐量水平、商品类型和操作程序已被确定为主要原因。单位:双引文:研讨会，ASHRAE交易，1988年，第94卷，pt。德克萨斯州达拉斯1号

Energy use efficiency of cooling systems varys with the type of cooler used. Vacuum coolers are the most efficient, followed by hydrocoolers, water spray vacuum coolers, and forced-air coolers. Levels of non-product heat input and operational practices have been identified as reasons for the differences. Energy use efficiency varys significantly within coolers of the same type. Level of product throughput, commodity type, and operational procedures have been identified as major reasons for this.Units: Dual
