Description
所属技术领域Technical field

背景技术Background technique
空气源热泵因其安装方便和节能越来越受到用户的青睐，但在北方地区的冬季低温环境中，其工作效率降低，甚至出现不能正常制热的现象。为此，日本大金推出了串连式双压缩机技术模式，试图以一台压缩机作功来提升第二台压缩机制热所必须的冷媒进口温度，还有的采用变频压缩机、大压缩比压缩机或变更冷媒、喷液增焓等等措施，更有一些公司采用在水箱中安装大功率的电热管直接加热热水的方法。显然，前者方案提高了技术的复杂性和增大了产品的制造成本，后者方案加重了系统的运行成本，又倒退到了电热水器的时代，从而使空气源热泵技术的节能优势荡然无存。Air source heat pumps are more and more favored by users because of their convenient installation and energy saving. However, in the low-temperature environment in winter in northern regions, their working efficiency is reduced, and even normal heating may not occur. For this reason, Japan's Daikin has launched a serial dual-compressor technology model, trying to use one compressor to work to increase the refrigerant inlet temperature necessary for heating the second compressor, and some use frequency conversion compressors, large compression Compared with compressors or changing refrigerants, spraying liquid to increase enthalpy, etc., some companies use the method of directly heating hot water by installing high-power electric heating tubes in the water tank. Obviously, the former scheme increases the complexity of the technology and increases the manufacturing cost of the product, while the latter scheme increases the operating cost of the system and regresses to the era of electric water heaters, thus making the energy-saving advantages of air source heat pump technology disappear.
由本人在先申请的“一种自体循环换热与强制增焓的热泵热水器”(200920156174.1)技术提供了在冬季运行时可采用自体循环换热的方案，但其缺点是增设的连体换热水箱占地面积大，安装不便，同时也增加了制造成本，不利于推广。The technology of "a heat pump water heater with self-circulation heat exchange and forced enthalpy increase" (200920156174.1) that I applied for earlier provides a scheme that can adopt self-circulation heat exchange during winter operation, but its disadvantage is the additional conjoined heat exchange The water tank occupies a large area, is inconvenient to install, and also increases the manufacturing cost, which is unfavorable for popularization.
