目前国内生产氨用空气冷却器和氟利昂用空气冷却器的厂家不少,但由于试验条件的限制,多数产品都未经过试验。嵊县制冷热交换器厂从86年开始即已生产冷库用低温氟利昂空气冷却器,其中DD12—2.0/12空气冷却器经烟台冷冻机厂在该厂生产的26m~3组合冷库中使用,已取得较好的效果。为了确定该空气冷却器的传热性能将委托上海水产大学食品工程实验室进行了制冷量和传热系数测试。
At present, there are many domestic manufacturers of air coolers and freon air coolers, but due to the limitations of test conditions, most of the products have not been tested. Shengxian Refrigeration Heat Exchanger plant has been producing low-temperature Freon air cooler for cold storage since the beginning of year 86. Among them, the DD12-2.0 / 12 air cooler is used by Yantai Freezer Factory in 26m ~ 3 combined cold storage produced by the plant. Achieve better results. In order to determine the heat transfer performance of the air cooler, the food engineering laboratory of Shanghai Fisheries University will be commissioned to test the cooling capacity and heat transfer coefficient.
