一种地源热泵与冰蓄冷协同冷暖系统研究

Research on a Coordinated Cooling and Heating System for Ground Source Heat Pump and Ice Storage

针对通常的三工况地源热泵与冰蓄冷耦合(联合、复合)系统调节不灵活,难以解决冷热负荷需求差别大的问题,提出并构建了一种地源热泵与冰蓄冷协同冷暖系统,并确定了协同冷暖系统的供冷策略和供热策略。既可以避免机组在较低负荷下的低效率运行,又可以在一定程度上平抑机组负荷的波动。

Aiming at the problem that the coupling of the ground source heat pump and the ice storage cold coupling( combined and composite) system is not flexible in the normal three working conditions,it is difficult to solve the problem of large difference between the hot and cold load requirements,and a ground source heat pump and ice storage cold coordination heating and cooling system is proposed and constructed. And carry out the engineering construction of the collaborative cooling and heating system. The study identified the cooling strategy and heating strategy for the coordinated cooling and heating system. It can not only avoid the low-efficiency operation of the unit under lower load,but also can restrain the fluctuation of the unit load to a certain extent.
