摘要：

采用Ebsilon软件构建了海产养殖余热回收和热泵供热系统的热力循环模型，通过仿真计算分析了一个典型的海产养殖热泵系统工程案例的系统缺陷。经过优化，系统能效提高一倍左右，以青岛地区冬季室内一个海参育苗池为例，日节电可达2 000 kW·h，节能潜力巨大，经济效益显著。研究表明，利用热泵回收海产养殖排水余热，最关键的是要遵循“温度对口，梯级利用”的科学用能原则。

Abstract:

The Ebsilon software was employed to establish a thermodynamic cycle model of a typical heat pump heating system by utilizing the waste heat in marine aquaculture. Simulations were carried out to find out the defects of the heat pump system for a typical engineering case. The optimization of the heat pump system was carried out, and a doubled energy efficiency was obtained. In the case of an indoor sea cucumber seedling plant in Qingdao sea area, electricity saving is up to 2 000 kW·h each day in winter. The energy saving potential is tremendous, and the economic benefit is remarkable. The case analysis shows that the critical point is to follow the essential scientific principle of"temperature counterpart and cascade utilization" when reusing the waste heat of drainage in mariculture by a heat pump system.

Key words: waste heat recovery, heat pump, Ebsilon software, marine aquaculture, thermodynamic cycle
