在以往的高温冷藏库设计中,通风换气量的确定主要考虑消除食品贮藏期中的异味和供给贮藏食品呼吸所需要的空气量,一般昼夜换气量按库房容积3倍考虑。这样算出的新风量是很小的。因此要维持食品所需要的冷藏温度,一年四季都需要开冷冻机,即使在冬季也要耗费大量的电能。在北方冬季气候寒冷,有大量的天然冷源,能否不开冷冻机直接采用室外风进行高温冷藏呢?我们在邯郸市水果批发部2#高温冷库设计中进行了尝试,通过几年的使用,反映效果良好,经济效益显著。
In the past design of high-temperature refrigerator, the ventilation ventilation to determine the main consideration to eliminate the odor of food storage and storage of food supply for breathing the amount of air required, usually day and night air volume according to the warehouse volume of 3 times to consider. The amount of fresh air calculated in this way is small. Therefore, in order to maintain the required refrigerating temperature of the food, it is necessary to open the freezer all year round, and consume a large amount of electric energy even in winter. In the northern winter cold weather, a large number of natural cold source, can not open the freezer directly using outdoor wind for high temperature refrigeration it? We Handan City Department of fruit wholesale 2 # high temperature cold storage designed to try through several years of use , Reflecting the good results, significant economic benefits.
