摘要
随着对臭氧层破坏和温室效应的不断关注,高GWP值制冷剂的使用将不断受到限制,自然制冷剂和近自然制冷剂将得到快速发展,其中CO_2作为自然制冷剂将发挥重要作用。本文介绍CO_2作为制冷剂的一般特性及其原理,总结CO_2热泵热水机采用的标准及其优势,并介绍其国内外发展现状,呼吁进一步发展CO_2热泵热水机。
With the constant attention to the destruction of ozone layer and greenhouse effect, the use of high-GWP refrigerants will continue to be limited. Natural and near-nat- ural refrigerants will develop rapidly. CO2 will play an important role as a natural refriger- ant. The general characteristics and cycle principle of CO2 as a refrigerant are introduced. The standards and advantages of CO2 heat pump water heaters are summarized. The development status at home and abroad are listed. It is called for further development of CO2 heat pump heat water heaters.
