Analysis Of The Dilatancy Technology Of District Heating System With High-temperature Heat Pump

The article described the dilatancy technology of district heating system withhigh-temperature heat pump (HTHP). For the exploitation of low-temperature returnnetwork sources, a high-temperature heat pump with a heat exchanger was planned.As the core technology of the dilatancy district heating system, HTHP units and heatexchanging systems had been described detailedly through theoretical andexperimental analysis.Comparing with other refrigerants, BY3#has the best of the thermal performancein the higher evaporation temperature conditions by experiment analysis. It usesmultiple regression analysis method to build up the mathematical model of COP(coefficient of performance) in the high temperature heat pump experiment. On thebasis of the experimental data, the functional formula of the COP changed with watertemperature of the condenser and evaporator on the exit/entrance, and the quantity ofheat is concluded. Multiple regression analysis method plays an important role in thescreening of the refrigerations.The article describe the dilatancy technology of district heating system withhigh-temperature heat pump (HTTP). For the exploitation of low-temperature returnnetwork sources, a high-temperature heat pump with a heat exchanger was planned. Inthis paper the district heating system is taken as a case study. The main characteristicsof the dilatancy district heating system are presented in the form of diagrams. Theprincipal advantage of dilatancy technology in the district heating system lie inincreasing the temperature difference, reducing the diameters and the initialinvestment of primary side network, and saving the operation consumption.This papershows clearly the analysis of the dilatancy technology for characterizing andimproving the performance of district heating systems.The thermodynamic characteristics of the dilatancy technology in the districtheating system is studied theoretically and experimentally in this paper.The concepts,analysis principles, development and applications of exergy analysis and energyanalysis were reviewed. In the dilatancy technology of district heating system.
