变风量空调系统自然冷却节能设计

Energy saving design of natural cooling for VAV air conditioning systems

结合变风量空气处理系统的设计,介绍了利用室外低温低比焓空气供冷的自然冷却节能技术。对该节能技术的两种形式——空气节能器与水节能器进行了比较。给出了空气节能器的判别控制方法及各方法的适用地区。最后介绍了设计时的注意要点。

With the desigh of VAV air conditioning system, presents the energy saving technology of natural cooling by cooling air conditioned rooms with outdoor air of low temperature and low enthalpy, Compares the two energy saving modes, i.e. air economizer and water economizer. Represents the control discrimination methods of air economizer and their applicability. Gives some important points to be noted during design process.
