摘要
Abstract
In order to further study water source heat pump projects,we generally introduced a water source heat pump project and its water drawing and draining scheme,calculated the water intake in summer conditions,normal winter conditions,and extreme winter conditions,built a 3D diagram of the water drawing and draining part,used CFX to numerically simulate the effects of water drawing and draining on the river in the three conditions,and analyzed the energy conservation effect of water source heat pump.Results showed that in the 3 conditions,the draining streams have no effect on the temperature field around the upstream water inlet in River A.Compared with the basic temperature of River A,the average water temperature of River B before joining River A fluctuates by less than 1℃,meaning the water draining has no effect on River A.The energy conservation effect of the project is prominent.The study on the effect of water drawing and draining by water source heat pumps on the temperature field of rivers and the energy conservation effect of the project can provide reference for the design and optimization of water source heat pump projects.关键词
