The Research Of Water Temperature Based On Water Source Heat Pump And Inpact Assessment To Thermal Environment

When the energy and environmental issues is becoming an international issue, lots ofmajor areas have begun to focus on the new environmental and energy saving technology.The building environment field is no exception, either. The heat pump technology is one ofthe new technology. Water can be used as the low heat source of heat pump .Water sourceheat pump air conditioning is a new type of energy utilization devices with the advantages ofhigh efficiency, saving energy, green environmental protection, low operating cost, sustaina-ble utilizing. So it has been used widely at home and abroad. Lake water source heat pumpbelongs to one of the water source heat pump.Based on the FLUENT simulation software, on existing project designing as an example,this paper simulated the temperature distribution in water from which extract cold and heatenergy. The study take the lake surrounding the project as the object, considered the locationof the project and the equipments used in the project. It focuses on varying range and extentof the lake after emissions of heat and cold to the lake so that we can know the law of thevariation of water temperature. If the effection to the lake is minor, and the effection is in therange of laws, we can take the lake as the heat sources or heat sink of surface water sourceheat pump. Because this new technology changed the water temperature distribution of thelake, it may affect the water environment in some extent. When the temperature field issimulated, we will set our sights on the effection of ecological environment after releasingheat to the lake.The results show that, using the surrounding water as low heat of this work can meet thenew demands of energy efficient. However, it will break the ecological environment of thelake. As long as we can take measures to prevent these undermine from spreading, andreal-time monitoring and to take effective measures, we Will be able to control these effectswithin a certain range to achieve the environmental requirements. All of these can prove thatusing the surface water source heat pump water as a heat source or heat sink is feasibility.
