摘要
在只考虑环境因素和天气的情况下提出了太阳能热泵热水系统调度策略,以提高对太阳能的利用。首先在空气源热泵加热系统动态方程的基础上,给出了空气源热泵制热量的预测方法,然后从能量的角度给出调度策略的运行步骤,在求得热泵制热量的基础上,对当前热水所含的热量与目标热水所含热量进行比较,求取热泵开启的时间,实现对热泵的控制。通过在实际工程中的应用比较,证明该节能运行策略能够推迟热泵的开启,进而缩短热泵的运行时间,太阳能利用率得到了一定的提高。
The scheduling strategy was put forward only in the case of environmental and weather conditions, in order to improve the utilization of solar energy . Firstly, a forecast heat production method of heat pump was given, based on heat pump heating system dynamic equation. Then, the steps of the energy saving strategy was given from the view of energy. Based on the heat production of heat pump, using comparison between the heat contained in the current hot wa- ter and the heat contained in the target hot water, the starting time of heat pump can be obtained to control heat pump. Compared with the existing strategy practical engineering application, it was proved that the energy saving operation strategy could delay the opening time of the heat pump, shorten the running time of the heat pump, and improve the u- tilization rate of the solar energy.
