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
