正确设计的冷藏库的墙板、顶板和地板组成了一个完整的隔热系统,不仅使热量传递降低到最小,而且控制了湿气的渗透。冷库围护结构的质量直接影响到制冷装置的投资和经营管理费用。冷库围护结构一般都有电气管线、水管、制冷管道和钢结构构件穿过。所有穿孔都有可能由于增加热量传递有湿气侵入库内而影响隔热体的质量,这将增加制冷机的负荷,从而增加运行电耗。一个安装不好的电气穿管是容易识别的。热湿空气接触冷的金属表面后会在上面结露。
Properly designed refrigerator walls, roofs and floors form a complete insulation system that not only minimizes heat transfer but also controls moisture infiltration. The quality of the cold storage enclosure structure directly affects the investment in refrigeration equipment and operation and management costs. Cold storage enclosures generally have electrical plumbing, water pipes, refrigeration pipes and steel structure components through. All perforations may affect the quality of the insulation by increasing the amount of heat transferred to the interior of the reservoir, which increases the load on the refrigerator and increases the operating power consumption. A poorly installed electrical conduit is easily identifiable. Hot and humid air will contact the cold metal surface in the above condensation.
