目前我国肉类加工企业制冷系统的冷凝废热大多数没有回收利用。以下面计算分析的某屠宰猪加工能力2000头/班、冻结140吨/日、冷藏容量10000吨的肉联厂为例,制冷系统的冷凝废热约为547×10~4KJ/h(130.64×10~4kcal/h),这部分热量由于品位低而白白的浪费了。不仅如此,系统 At present, most of the condensing waste heat of the refrigeration system in China’s meat processing enterprises are not recycled. Take the following calculation and analysis of a slaughtered pig processing capacity of 2000 head / class, frozen 140 tons / day, refrigerated capacity of 10,000 tons of meat factory as an example, the cooling system of the condensing waste heat is about 547 × 10 ~ 4KJ / h (130.64 × 10 ~ 4kcal / h), this part of the heat due to low quality and wasted. Not only that, the system
