摘 要:圍繞如何發(fā)展低碳經(jīng)濟的問題, 專家學者提出了各種有價值的意見和建議, 包括借鑒國際經(jīng)驗、開展試點、制定相關(guān)經(jīng)濟政策措施等。具體到暖通行業(yè), 在這種大背景下, 同樣存在著要不斷在技術(shù)手段上改進提高, 節(jié)能降耗, 順應(yīng)時代發(fā)展。 溫濕度獨立控制是暖通空調(diào)節(jié)能的一種方法，本文從溫濕度獨立控制的原理出發(fā)，研究探討它與傳統(tǒng)的熱濕聯(lián)合處理方式的不同，從而說明溫濕度獨立控制為什么節(jié)能；接著闡述了溫濕度獨立控制的設(shè)計方法；最后利用實例說明溫濕度獨立控制的節(jié)能。 溫濕度獨立控制空調(diào)系統(tǒng)，通過新風排除室內(nèi)余濕、二氧化碳，室內(nèi)余熱的排除通過輻射板（或干式風機盤管）來實現(xiàn)。它采用溫度與濕度兩套獨立的空調(diào)控制系統(tǒng)，分別控制室內(nèi)的溫度與濕度，避免了常規(guī)空調(diào)系統(tǒng)中熱濕聯(lián)合處理所帶來的能量損失。它可以滿足不同房間熱濕比不斷變化的要求，避免了室內(nèi)相對濕度過高或者過低的現(xiàn)象，是一種高效節(jié)能的空調(diào)系統(tǒng)。它的特點是用干燥新風通過變風量方式調(diào)節(jié)室內(nèi)濕度, 用高溫冷水通過獨立的末端( 輻射或?qū)α鞣绞? 調(diào)節(jié)室內(nèi)溫度。 研究說明，溫濕度獨立控制空調(diào)系統(tǒng)并不是在所有情況下都是節(jié)能的，設(shè)計時一定要注意使用條件。 關(guān)鍵詞：溫濕度獨立控制，暖通空調(diào)，能效比，節(jié)能
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.
