Application and Analysis of a Heat Pump System for Building Heating and Cooling Using Extracting Heat Energy from Untreated Sewage
نویسندگان
چکیده
Heat pump technology can extract low-level heat energy from urban sewage to or cool buildings, which alleviate the two major problems of shortage and environmental pollution a certain extent. This paper introduces principle wastewater source summarizes current common system forms their key core technologies. The proposed special transfer for effectively solve problem blockage corrosion in process transfer. Taking an office building Qingdao as example, design parameter is introduced detail. operation monitoring heating air conditioning seasons this project was completed through data collection system, various performance parameters were studied analyzed. obtained using measured one year operation. testing results show that temperature winter approx. 13.5 °C, hot water supply 50 average COP unit 3.95, 2.96. calculation consumption only 50.81% traditional mode coal-fired boiler 57.57% system. In summer, 22 cold-water 5.5 4.45, 3.25. cooling 79.39% chiller 61.56% shows has remarkable energy-saving effect.

Heat exchanger technology and applications: ground source heat pump system for buildings heating and cooling
The earth’s surface acts as a huge solar collector, absorbing radiation from the sun. In the UK, the ground maintains a constant temperature of 11-13oC several metres below the surface all the year around.1 Among many other alternative energy resources and new potential technologies, the ground source heat pumps (GSHPs) are receiving increasing interest because of their potential to reduce prim...
متن کاملEnergy efficiency in a building complex through seasonal storage of thermal energy in a confined aquifer
Confined aquifers are formations surrounded by impermeable layers called cap rocks and bed rocks. These aquifers are suitable for the seasonal storage of thermal energy. A confined aquifer was designed to meet the cooling and heating energy needs of a residential building complex located in Tehran, Iran. The annual cooling and heating energy needs of the buildings were estimated to be 8.7...
