Analysis And Research Of Characteristics Of Water Source Heat Pump Cooling And Heating System In Shenyang Area

This paper first introduces the principle of water source heat pump system,characteristic and the superiority of application in shenyang area;Then in practical engineering,for example,using the DeST building energy simulation software,the water source heat pump system and other several common cold heat source system to carry on the economical comparison,concludes that water source heat pump system of initial investment and operation cost is the lowest,the initial investment is lower than other common cold heat source system 11?38%,and its heating and cooling in the total cost is lower than other common cold heat source system 25?70%;Combined with the practical application of water source heat pump system in shenyang area,pointed out that in order to eliminate the inevitable defects in design and equipment of choose and buy and artificial operation error of operation and management,water source heat pump room set up energy-saving control system is necessary;To solve the problem of groundwater recharge:on the one hand,on the operation and management must be for dynamic monitoring of groundwater recharge quantity and water quality;On the other hand to ensure that the groundwater recharge well hydraulic balance between groundwater backwater pipes should be arranged into ring,and the design main water should not higher than 2 m/s.Finally,combining with the actual engineering of the optimization of both the water source heat pump system transformation,in the year before and after the water source heat pump system to optimize the operation energy consumption monitoring and statistics,and analyze the results and conclusion:use of underground water supply system,obtaining free cold source,the summer air conditioning refrigeration operating cost can save 20-30%;For indoor use independent"behavior" for changes in temperature and low temperature floor radiation air conditioning system,reduce the hot water outlet temperature of the heat pump units in winter,when the temperature of the hot water for 30/35? winter heating system operation cost save about 14.2%.
