Medium and Deep Geothermal Heating Technology Program of A Company's Science and Technology Park Project
The heating area of the project is about 1.14×105 m2,with a total heat load of 7 000 kW,adopting medium and deep geothermal heating,with an average heat load of 4 859.09 kW,and the annual heat consumption of the project is 62 959.68 GJ.The heat source is a water-heated geothermal well,and it is constructed in accordance with the mode of"one mining and one irrigation,rechargeable in the same layer,and heat extraction without water consumption",with one supporting reinjection well.It utilizes the medium and deep geothermal water as the heating heat source,provides 45℃/40℃heating circulating water in winter,and adopts the method of"plate exchange direct supply+heat pump unit peak adjustment"to supply heating for the project.According to the calculation of 30-year operation period,the medium and deep geothermal program can save 1.127 738×108 yuan compared with the natural gas boiler program.
