中高温热泵热水装置的研制与实验研究

基于生产过程中对中高温工艺热水的需要和采用常规工质的中低温热泵热水装置的不足，研制了一种采用新工质的中高温热泵热水装置．实验表明，生产温度为60—90℃的热水时，其工作压力低于1．4MPa，制热系数大于3．4．其采用常规部件构建工业化装置，为干燥、杀菌、漂烫、清洗、供暖等领域提供了一种较好的热水制取装置．

Development and Experimental Study of a Mid-High Temperature Heat Pump Water Heatear

In order to meet requirements of mid-high hot water used in processing industry, and overcome shortcomings of traditional heat pump water heaters with conventional refrigerants, a mid-high temperature heat pump water heater was developed and was experimentally studied. Experiments show that it could work with the pressures lower than 1.4 MPa, and its coefficient of performance is higher than 3.4 when hot water of 60 - 90 ℃ was produced. It can make use of common components to fabricate practical equipment, and provide a competent method for hot water supply in drying, sterilizing, scalding, rinsing, space heating fields, etc.
