阻霜型空气源热泵多用机中央空调的应用

Application of Frost Resistance Type Air Source Heat Pump Multi-Purpose Central Air-Conditioner

本文论述了阻霜型空气源热泵中央空调热水两用机组,由单制热改进为制冷制热一机二用,解决了冬天极端气温下制热的融霜问题。在-30℃正常使用,化霜时产生的余热全部回收,装机功率比分体式空调可减少40%,而且在冬季化霜时升温快、能耗低。空气源热泵中央空调配套热水器系统与分体式空调配套聚热式电热水器系统相比,在非极端天气下,可节能约66%。在极端天气下,可节能50%。

The article discusses about frost resistance type air source heat pump central air-conditionerhot water double-purpose unit from single heating mode to cooling and heating mode, whichsolves defrosting problem in winter heating mode. The unit can work at the temperature of -30℃. Theunit recovers waste heat totally and installed power reduces 40% than split air-conditioner. The unitsupplies hotter air and costs lower energy consumptions while defrosting. Air source heat pump centralair-conditioner with hot water system compares with split air-conditioner with polythermo electric waterheater, which shows 66% energy saving at non-extreme weather and 50% energy saving at extremeweather.
