【摘要】：利用Fluent建立土壤源熱泵空調(diào)系統(tǒng)仿真模型,通過(guò)模擬結(jié)果與熱響應(yīng)測(cè)試所得結(jié)果的比較驗(yàn)證了模型的準(zhǔn)確性。該模型耦合了土壤源熱泵空調(diào)系統(tǒng)三大組成部分:負(fù)荷末端、熱泵機(jī)組以及地埋管換熱器。在此前提下,研究土壤源熱泵空調(diào)系統(tǒng)中不同地下水流速工況下熱泵機(jī)組COP的變化情況。結(jié)果表明,在常見(jiàn)的地下水流速0m/a至300m/a范圍內(nèi),地下水流速越大,熱泵機(jī)組COP越大,其中夏季制冷期間,當(dāng)?shù)叵滤魉購(gòu)?分別增加到60m/a,100m/a,150m/a,200m/a,250m/a,300m/a時(shí),機(jī)組COP分別增加11.54%,16.04%,19.91%,23.17%,25.50%,27.14%,從而減小了機(jī)組運(yùn)行能耗。
[Abstract]:The simulation model of ground source heat pump air conditioning system is established by using Fluent. The accuracy of the model is verified by comparing the simulation results with the results of thermal response test. The model coupling the three major components of the ground source heat pump air conditioning system: load end. Heat pump units and ground heat exchangers. On this premise, the variation of COP of heat pump units under different groundwater velocity conditions in ground-source heat pump air conditioning systems is studied. The results show that in the common groundwater velocity range of 0 m / a to 300 m / a, The higher the velocity of groundwater, the larger the COP of heat pump units. During the summer refrigeration period, when the flow velocity of groundwater increases from 0 to 100 m / a to 60 m / a to 100 m / a, respectively, when the water flow velocity is increased from 100 m / a to 150 m / a / a, the unit COP increases by 11.54 m / a, 16.04 m / a and 19.91m / a respectively, and 23.1725.50% 27.144.The unit energy consumption is reduced.
