随着我国化纤工业、纺织工业、电子工业及大型建筑空调事业的发展,对大型离心式制冷机组的需要日益增多,要求也越来越高。 240万大卡/时离心式制冷机是我国编制的R-12离心式制冷机系列的典型产品,也是当前我国单机容量最大的制冷空调冷水机组。该产品于1976年由一机部通用机械研究所等六单位联合设计,1977年一机部委托重庆通用机器厂试制。经过近三年的努力,在有关单位的支持和配合下,重庆通用机器厂于1979年完成了该产品的试制、试验,并完成了对产品的鉴定。经过性能测试,产品达到设计要求,在压缩机效率、机器重量指标及单位功率制冷量等主要指标方面,均接近国外同类产品的先进水
With the development of China’s chemical fiber industry, textile industry, electronics industry and large-scale building air-conditioning business, the demand for large-scale centrifugal chillers is increasing and the requirements are getting higher and higher. 2.4 million kcal / hour centrifugal chiller is our country’s R-12 centrifugal chiller series of typical products, but also the current stand-alone capacity of our largest chilled air-conditioning chiller. The product in 1976 by a machine-General Institute of Machinery and other six units jointly designed in 1977, a machine-commissioned Chongqing General Machinery Factory trial production. After nearly three years of hard work, with the support and cooperation of relevant units, Chongqing General Machinery Factory completed the trial manufacture and test of the product in 1979 and completed the appraisal of the product. After the performance test, the product meets the design requirements, the compressor efficiency, machine weight index and unit power cooling capacity and other major indicators are close to similar foreign advanced products water
