“…The heat pump used to capture waste heat from the data centre Except for the inherent performance characteristics of the HP, the operational conditions are the main factors that influence the energy performance of an HP [44]. The operational conditions include the inlet and outlet water temperature and the water mass flow rate on the evaporator and condenser sides of an HP [45]. Therefore, the HP compressor power may be expressed by a simple function involving the above mentioned operational conditions, as shown in Equation ( 11):…”

“…Meanwhile, corrosion and microbial attachment on heat exchanger may worsen the heat extraction ability of the heat pump unit. Seawater temperature is a critical factor influencing the energy efficiency of the heat pump, it is also important to prevent freezing when the outside is severely cold [37,38]. In order to extract heat more reliable, researchers suggested renovations in the heat exchange process [37,39].…”

“…In this study, both SWHP and ASHP are assumed to cover full building heating/cooling load, so no supplementary heating/cooling is considered ( = T sup( ) 0 i ). Electricity consumption of circulation pump is assumed to account for 25% of total heat pump system electricity consumption according to [63]. For coal boilers, system efficiency is set to be 0.75 according to [64].…”

Fossil fuel based building space heating and cooling contribute to more than 10% total final energy consumption in China. Consequent carbon dioxide and air pollutants emissions bring about atmospheric pressure and associated respiratory diseases. Seawater heat pumps as a candidate sustainable building space heating and cooling solution can alleviate such environmental pressure since China has a long coastline and many coastal cities have the possibility for seawater heat pump implementation. However, stakeholders are still suffering from insufficient understanding of seawater heat pumps feasibility in different coastal cities of China from technoeconomic, environmental and geographical perspectives. This paper proposes a systematic method to evaluate seawater heat pump potential in different locations of China considering various local spatial parameters in the source and sink side of the energy system. A key performance indicator system is introduced to quantitatively analyze the relative advantages and disadvantages of applying seawater heat pumps compared with status-quo systems. Quantitative evaluation results show that seawater heat pumps have a higher potential in north Chinese coastal cities from techno-economic point of view when compared with existing heating and cooling systems. Environmentally, seawater heat pumps have to reach a critical seasonal coefficient of performance value to guarantee its potential in carbon emissions saving. In south Chinese coastal cities, seawater heat pumps have to reach a more satisfactory system efficiency and a more competitive system cost in order to exploit its full advantages over status-quo systems from techno-economic perspectives. Environmentally, seawater heat pumps are more attractive than competing technologies in south cities. Also, north Chinese cities are geographically more feasible for seawater heat pumps applications compared with south cities.
