针对青海地区的气候特点及建筑供热情况,提出了一种综合利用太阳能和浅层地热能相结合的集中供热系统,介绍了系统的运行原理,结合当地的气象条件和建筑情况对复合系统进行了检测分析,结果表明节能效果十分明显,具有良好的推广价值和广泛的运用前景,即在热负荷需求较低的情况下,以太阳能供热系统为主、水源热泵供热系统为辅,可以节省运行费用;在太阳能利用受限制的气候条件下,以水源热泵供热系统为主、太阳能供热系统为辅的集中供热系统,这样达到既能保持最佳的运行效果又能获得最佳的节能性。
In view of the climatic characteristics of Qinghai and the heat supply in buildings, a new district heating system combining solar energy and shallow geothermal energy is proposed. The operation principle of the system is introduced. Combined with local meteorological conditions and building conditions, The results show that the energy-saving effect is very obvious, and has good promotion value and wide application prospect. That is, under the condition of low heat load demand, mainly taking the solar heating system as the main, the water source heat pump heating system as the supplement, Can save operating costs; in the limited use of solar energy climate conditions, mainly to water source heat pump heating systems, solar heating systems, supplemented by the central heating system, so as to achieve both the best operating results and get the most Good energy-saving.
