摘 要:围绕如何发展低碳经济的问题, 专家学者提出了各种有价值的意见和建议, 包括借鉴国际经验、开展试点、制定相关经济政策措施等。具体到暖通行业, 在这种大背景下, 同样存在着要不断在技术手段上改进提高, 节能降耗, 顺应时代发展。
温湿度独立控制是暖通空调节能的一种方法，本文从温湿度独立控制的原理出发，研究探讨它与传统的热湿联合处理方式的不同，从而说明温湿度独立控制为什么节能；接着阐述了温湿度独立控制的设计方法；最后利用实例说明温湿度独立控制的节能。
温湿度独立控制空调系统，通过新风排除室内余湿、二氧化碳，室内余热的排除通过辐射板（或干式风机盘管）来实现。它采用温度与湿度两套独立的空调控制系统，分别控制室内的温度与湿度，避免了常规空调系统中热湿联合处理所带来的能量损失。它可以满足不同房间热湿比不断变化的要求，避免了室内相对湿度过高或者过低的现象，是一种高效节能的空调系统。它的特点是用干燥新风通过变风量方式调节室内湿度, 用高温冷水通过独立的末端( 辐射或对流方式) 调节室内温度。
研究说明，温湿度独立控制空调系统并不是在所有情况下都是节能的，设计时一定要注意使用条件。

ABSTRACT:How to develop low-carbon economy, experts made a variety of valuable comments and suggestions including learning from international experience, carrying out pilot, developing relevant economic policy measures. Specific to the HVAC industry, in this backdrop, there are also the means to continuously improve the increase in technology, energy saving, development of the times.
Temperature and humidity independent control is a measure of energy saving in HVAC.This paper made a research about the differences between conventional HVAC system and temperature and humidity independent control system.;and then state the design method of temperature and humidity independent control system;and last explain why temperature and humidity independent control system can save energy through specific cases.
Temperature and humidity control air conditioning system, fresh air through the exclusion of more than indoor humidity, carbon dioxide, through the exclusion of indoor heat radiation plate (or dry coil) to achieve. It features two independent temperature and humidity, air-conditioning control system, respectively, the temperature and humidity control room, to avoid the conventional air conditioning system caused by heat and moisture combined treatment of energy loss. It is heat and moisture in different rooms to meet the changing requirements than to avoid the indoor relative humidity too high or too low, the phenomenon is an energy efficient air conditioning system. It is characterized by dry fresh air through the VAV mode adjust the indoor humidity, high temperature water through a separate terminal (radiation or convection) to adjust the room temperature.
Study shows that temperature and humidity independent control air-conditioning system is not energy saving in all cases,so attention must be paid in the conditions of use through the process of design.
