冷凝器是蒸汽压缩式制冷系统中不可缺少的主要设备,虽然目前国内制冷空调系统仍采用立式管壳式冷凝器配冷却水塔的形式,但许多使用单位已开始认识到蒸发式冷凝器具有管壳式冷凝器无法比拟的优点,并开始使用.国内在线使用的蒸发式冷凝器在制造、安装、使用和维修上还存在着一些不足,本文仅就工作中遇到的一些实际问题作一探讨.一、设备安装位置在实际使用中有一些用户把蒸发式冷凝器放置在库房之间,并在下面设置一个大水池.这种作法破坏了蒸发式冷凝器的工作环境和优点,蒸发式冷凝器应安装在通风良好的位置(如屋顶),而工作环境的相对湿度较低则有利于降低冷凝压力并提高其换热能力.蒸发式冷凝器在设计时已考虑了水的存贮,通过水泵使水循环使用,设置冷却水池不仅对蒸发式冷凝器的工作环境没有帮助,相反增加了投资,浪费了水资源.
The condenser is an indispensable main equipment in the vapor compression refrigeration system. Although the domestic refrigeration and air conditioning system still adopts the form of vertical shell and tube condenser with cooling water tower, many units have begun to realize that the evaporative condenser has a tube Shell condenser incomparable advantages, and began to use.Evaporative condenser used online in the domestic manufacture, installation, use and maintenance there are still some shortcomings, this article only on the work of some practical problems to be explored First, the installation location of the device In actual use, some users place the evaporative condenser between the storerooms and set up a large pool below, which undermines the working environment and advantages of the evaporative condenser. Evaporative condensation The device should be installed in a well-ventilated location (such as the roof), while the lower relative humidity in the work environment is beneficial to reduce the condensing pressure and increase its heat exchange capacity. The evaporative condenser has been designed with water storage in mind Water pumps make the water cycle, the installation of cooling water not only evaporative condenser working environment does not help, on the contrary increased investment, waste of water resources.
