摘要

在将集中供暖的旧建筑改造成几乎零能耗的建筑时,越来越多的空气热泵被使用。这些热泵通常连接到供暖系统,只在需要时产生热量。当外部温度和泵的COP最低时,对热量的需求最大。室外温度在白天变化,这意味着在COP较高的情况下,可以通过产生和储存热量来节省能源。为了确定COP值较高的时段,使用天气预报资料和COP曲线。这些数据可以对产热进行排序和选择时间段。这与建筑物的热需求曲线相结合,可以为热泵创建一个运行时间表。这项研究的目的是开发热泵控制方法,使改造后的建筑符合接近零能耗的建筑规范。根据热泵和天气条件,可以减少高达10%的供暖用电需求。

A control method for increasing the heat usage efficiency of nearly-zero-energy buildings with heat pumps
In the retrofitting of older buildings with central heating into nearly zero-energy buildings more and more air to water heat pumps are used. These heat pumps are normally connected to heating systems, producing heat only on demand. The greatest demand for heat occurs when the outside temperature and therefore the COP of the pump is lowest. Outside temperature varies during the day, meaning it is possible to save energy by producing and storing heat in a situation where the COP is higher. To determine the periods with higher COP values weather forecast data and COP curves are used. The data enables to rank and select time periods for heat production. This in conjunction with the heat demand curve of the building enables to create an operation schedule for the heat pump. The aim of the study is to develop heat pump control methods for renovated buildings to comply with nearly zero energy building codes. Dependant on the heat pump and weather conditions, up to 10% of the electricity demand for heating can be decreased.
