Adsorption refrigeration is advantageous for environmental friendliness and energy conservation , so it is a promising alternative to traditional vapor compression refrigeration , and concerned by many scientists in the world 吸附制冷所具有的環境友好和節能等特性使其成為傳統的壓縮式制冷有前途的替代技術之一,并受到世界各國科技人員的關注。
It is discussed in this paper that the possibility of vapor compression refrigeration technology applied in the area of portable refrigeration , and a refrigeration scheme is presented which is based on a three phase variable frequency and adjustable speed miniature compressor 通過對現階段國內外便攜式制冷技術的研究,本文主要探討了蒸汽壓縮式制冷技術應用于便攜式制冷領域的可能性,由此提出采用三相變頻壓縮機的制冷方案。
According to the thermodynamics theory of vapor compression refrigeration cycle , hfc - r134a is chosen as refrigerant fluid and the thermodynamics calculation of refrigeration system is accomplished , which is based on the table of r134a thermodynamics characteristics and estimate of portable refrigerator ' s calorific burthen 本文根據蒸汽壓縮式制冷循環的熱力學原理,從小冷量、小體積的便攜式冷藏箱的熱負荷計算出發,以所選用制冷劑( r134a )的熱力性質表為依據,進行了制冷系統的基本熱力計算。
The system adopts several technologies , such as recovery of condensing heat , thermal storage and heat pump , etc . it can synthetically utilize energy of compression refrigeration cycle and satisfy the need of air conditioning and domestic hot water simultaneously . at the same time , its application will improve some problems of the conventional system ( an air conditioner and a hot water heater ) , such as large consuming energy , wasting energy and thermal pollution to environment . therefore , hpacdhws is obviously in favor of development economy , environment and society 該設備能全年綜合利用壓縮式制冷循環的能量(冬季運行要依靠輔助熱源) ,并融合了熱回收、蓄熱和熱泵等多項技術,能夠同時滿足建筑物內空調和生活熱水的需求,緩解了常規系統(常規空調器+熱水器)能耗大、能源浪費和環境熱污染等問題,具有明顯的經濟效益、環境效益和社會效益。
