如今，许多现有的再热式暖通空调系统都在使用。其中大部分可以通过相当简单的方式进行改造以节约能源。本文总结了当今一些更常用的技术。其中包括使用鉴别器、增加空气控制外的经济周期、将定容系统转换为可变风量（VAV）以及其他方法。在进行这些更改时，有必要避免不必要的复杂性，并避免对建筑环境控制有害的影响。 引文:研讨会，ASHRAE交易，1984年，第90卷，pt。密苏里州堪萨斯城2B

A great many existing reheat-type HVAC systems are in use today. Most of these could be retrofitted to conserve energy in fairly simple ways. This paper summarizes some of the more commonly used present-day techniques. These include the use of discriminators, addition of economy-cycle outside air control, conversion of constant volume systems to variable air volume (VAV), and other methods. In making these changes it is necessary to avoid unnecessary complexity and avoid effects detrimental to the building environmental control.
