组合空调机组表冷器计算的若干问题

Several Problems of the Surface Cooling Calculation in Combinatorial Air Conditioning Units

空调系统的正常有效运行,是由系统的正确设计、可靠施工和先进的控制系统所决定的,空调系统中的主要设备—组合空调机组的过滤器阻力取值、机组附加热交换能力及表冷器性能的计算尤为关键。本文就有关问题加以分析,并提出一种对表冷器设计选型、校核计算的方法:在具有干球效率安全系数α=1.0时的热工性能值,推算出该表冷器α≠1.0时的热工性能值。

The normal operation of the air conditioning system is effective by correct systems design,reliable construction and advanced control system.The resistance value of filters,the added heated exchange value and the performance calculation to surface cooling on the calculation of the main equipment of the air conditioning unit were particularly critical.This paper analyzed several problems,and puted forward a design selection of surface cooling and checking calculation method： thermal performance of surface cooling in a dry ball efficiency safety coefficient α=1 put out thermal performance in coefficient α≠1.
