针对严寒地区的气候条件,选取哈尔滨地区某居民住宅小区作为研究对象,利用TRNSYS软件对太阳能-土壤源热泵联合供暖系统(SGCHP)进行计算分析。结果表明:太阳能-土壤源热泵联合供暖系统中太阳能集热器对热泵机组的进水温度和COP以及节电量等方面有改善作用;对太阳能-土壤源热泵联合供暖系统中太阳能集热器面积与地埋管管长的最佳配比的优化结果表明,1 m~2太阳能集热器可保证17~27 m长的地埋管取热平衡。并继续模拟了沈阳地区,并以哈尔滨地区为基准,给出严寒地区该参数的推荐值。 相似文献

Numerical simulation of solar assisted ground-source heat pump heating system with latent heat energy storage in severely cold area 总被引:1,自引:0,他引:1

Solar assisted ground-source heat pump (SAGSHP) heating system with latent heat energy storage tank (LHEST) is investigated. The mathematical model of the system is developed, and the transient numerical simulation is carried out in terms of this model. The operation characteristic of the heating system is analyzed during the heating period in Harbin (N45.75°, E126.77°). From the results of the simulation, the average coefficient of performance (COP) of the heating system is 3.28 in heating period. In the initial and latter heating period, the COP of the heating system is higher, and the highest value is 5.95, because the system can be operated without heat pump. During the middle heating period the COP of the heating system and the operation stability of the system are improved due to solar energy and soil alternately or together as the heat source of heat pump. LHEST is a very important role in operation of the system. The system can be operated more flexibly, effectively, and stably by the charge and discharge heat of LHEST, and the effect becomes especially obvious in the initial and latter heating period. 相似文献

Energy performance of office building envelope designs in the five major climate zones – severe cold, cold, hot summer and cold winter, mild, and hot summer and warm winter – in China was investigated. A major city within each climate zone was selected. These were Harbin, Beijing, Shanghai, Kunming and Hong Kong. Generic building envelopes were developed based on data gathered from building surveys, local energy codes and the ASHRAE Standard. The overall thermal transfer value (OTTV) method and the heating degree-days technique were adopted in the analysis. Cooling and heating requirements due to heat gain/loss through the building envelopes were determined based on the respective OTTV parameters and building load coefficients. Different shape coefficients were also considered. For a typical floor, chiller load due to heat gain through the building envelope varied from 1.0 kW h/m2 in Kunming to 23.5 kW h/m2 in Beijing, and the heating load ranged from 2.7 kW h/m2 in Hong Kong to 124.3 kW h/m2 in Harbin. 相似文献
