摘　　要：通过对现有热泵循环过程的全面分析,提出了一种新型的多用途热泵。该热泵有蒸汽释放出气态显热的高温换热器、工质释放出液化潜热的中温换热器(冷凝器)和工质释放出液态显热的低温换热器。计算表明,与采用相同循环工质的现有热泵相比,该新型热泵具有更高的制热系数。它可以应用于家庭、学校以及企事业等单位的采暖/空调、沐浴以及开水供应等。By analyzing the current cyclical process of heat pump, a kind of new-type multiuse heat pump was proposed. In this system, the sensible heat of steam is released in high-temperature heat exchanger, liquefaction latent heat and liquid sensible heat of the cycle fluid are released in moderate-temperature heat exchanger （condenser） and low-temperature exchanger respectively. Calculation showed that the heating coefficient of the new heat pump is higher＇than existing heat pump under the same cycle fluid. The new-type multiuse heat pump is fit for the family, school, enterprise and institution to provide heating/air condition, bathing and boiling water, etc..
