【正文】 eve yearly targets for improvements, which have, in a sense, the same implications as laws. In a prolonged recession, investments in energysaving activities directly linked with cost reduction have attracted increasing attention. However, largescale renewal investments which entail enormous costs cannot be implemented easily. Consequently, there have been increasing needs for energy conservation activities which bring about substantial cost reduction effects but can be conducted inexpensively with ease and minimum risks, while at the same time utilizing existing facilities. Figure 1 is a graphical indication of the energy consumption ratios of office buildings, which is based on research conducted by the BuildingEnergy Manager39。本文將著重介紹系統(tǒng)的原理基本功能以及部分實(shí)際應(yīng)用情況。 圖 1 辦公室各種設(shè)備能量消耗的情況 在眾多的關(guān)于空調(diào)的技術(shù)中,我們已經(jīng)把目標(biāo)集中在空調(diào)泵上,并制造出一種“經(jīng)濟(jì)型”的新型節(jié)能控制系統(tǒng),這個(gè)系統(tǒng)迎合了先前系統(tǒng)所缺少的需求。 回顧先前空調(diào)系統(tǒng) 圖 2顯示了空調(diào)的內(nèi)部系統(tǒng),分析先前空調(diào)系統(tǒng),從總體上講,能源主要以散熱,水泵,通風(fēng)裝置的 形式消耗。 不規(guī)則空調(diào)系統(tǒng)的構(gòu)造指示了冷 /熱水的流經(jīng)方向通過(guò)加熱產(chǎn)生的冷 /熱水被回流到主要水泵當(dāng)中,應(yīng)承對(duì)恒溫水的要求很高,次要水泵主要負(fù)責(zé)輸送要求的水量
