进行了一项研究，调查空间供暖和生活热水系统的能源需求以及住宅热泵的电力需求。考虑了一个由 96 间两居室、三居室和四居室房屋组成的住宅区。对隔热不良的旧建筑和隔热良好的新建筑的能源需求和电力需求进行了调查。计算了整个住宅区热泵的电力需求。考虑了室温设置、热水使用、热泵热容量和建筑隔热对住宅区电力需求的影响。研究发现，热水消耗对能源需求和电力需求有显着影响。对于小型、隔热良好的建筑来说，热水系统的能源需求可能比空间供暖系统的能源需求高出 3.5 倍。室温设定值和热水消耗量的降低可降低平均能耗。然而，峰值功率要求并未受到显着影响。因此，需要采取不同的控制策略，例如能源需求转移，以减少电力峰值。
A study was undertaken to investigate the energy demand for space heating and domestic hot water systems as well as the electrical power requirement for heat pumps in residential dwellings. A residential area of 96 two, three and four bedrooms houses was considered. Energy demand and power requirements in old poorly insulated buildings and in new, well insulated buildings were investigated. The requirement for electrical power for the heat pumps in the whole residential area was computed. The effect of room temperature settings, hot water use, heat pump thermal capacity and building insulation on the power requirements in the residential area was considered. It was found that hot water consumption has a significant effect on energy demand and power requirements. The energy demand for hot water systems may be up to 3.5 times higher than that for space heating for small, well insulated buildings. A reduction of the room temperature setpoint and hot water consumption reduces average energy consumption. However, the peak power requirements are not significantly affected. Therefore a different control strategy, such as energy demand shifting, is needed in order to reduce electrical power peaks.
