一、前言从空调负荷看夏季由排风损失的冷量相当大,排风损失的冷量随新风比的增大而增加,直流系统冷损失为最大;我国幅员辽阔,北方气候寒冷,冬季排风损失的热量相当可观,许多厂房工艺设备排除废热也很普遍。若能用换热器回收这部分冷量、热量达到节能目的是具有重大意义的。用什么样换热器回收这部分能量呢?日本昭和铝公司曾把热管换热器和几种常规换热器作了比较,见表1。
First, the preface From the air conditioning load summer to see the loss of exhaust by the cooling capacity is quite large, exhaust loss of cold with the increase of fresh air ratio increases, the DC system, the greatest loss of cold; China’s vast territory, the northern climate is cold, the winter row Wind loss of considerable heat, many plant equipment to eliminate waste heat is also very common. If you can use the heat exchanger to recover this part of the cold, heat energy saving purposes is of great significance. What kind of heat exchanger to recover this part of the energy it? Japan Showa Aluminum heat pipe heat exchanger and several conventional heat exchangers have been compared (Table 1).
