Waste Heat Utilization

This article examines the possibilities of using waste heat in a building for the production of medical products. During the production, 6 compressors operate continuously, and the generated excess heat is removed through coolers or partially used in building heating, ventilation and domestic hot water production systems. The aim of this article is to model and evaluate the possibilities of using waste heat after performing the analysis of heat flow demand of all the engineering systems. The pinch method is used to achieve this goal. Heat flows and heat exchanger network are modelled using PinCH 3.0 software. The performed assessment shows that with the help of pinch analysis, in the analysed object it is possible to recover and use more than 20% of waste heat as compared to the initial design variant.

AbstractSuccessful hot-water drilling in the Antarctic is predicated on utilization of the abundant water supply available in the form of the Antarctic ice sheet. For WISSARD (Whillans Ice Stream Subglacial Access Research Drilling) field operations, a snowmelting system was developed that could adequately provide water for a 1000 kW hot-water drill. The system employs ∼100 kW of waste heat from a 225 kW generator to melt snow for initial water (known as seed water) to prime the drill’s high-pressure pumps and water heaters; once the water heaters can be engaged in snowmelting, enough water can be supplied directly to the WISSARD drill to successfully melt a 40 cm diameter hole through 800 m of ice.

District heating enables an economical use of energy sources that would otherwise be wasted to cover the heating demands of buildings in urban areas. For efficient utilization of local waste heat and renewable heat sources, low distribution temperatures are of crucial importance. This study evaluates a local heating network being planned for a new building area in Trondheim, Norway, with waste heat available from a nearby ice skating rink. Two alternative supply temperature levels have been evaluated with dynamic simulations: low temperature (40 °C), with direct utilization of waste heat and decentralized domestic hot water (DHW) production using heat pumps; and medium temperature (70 °C), applying a centralized heat pump to lift the temperature of the waste heat. The local network will be connected to the primary district heating network to cover the remaining heat demand. The simulation results show that with a medium temperature supply, the peak power demand is up to three times higher than with a low temperature supply. This results from the fact that the centralized heat pump lifts the temperature for the entire network, including space and DHW heating demands. With a low temperature supply, heat pumps are applied only for DHW production, which enables a low and even electricity demand. On the other hand, with a low temperature supply, the district heating demand is high in the wintertime, in particular if the waste heat temperature is low. The choice of a suitable supply temperature level for a local heating network is hence strongly dependent on the temperature of the available waste heat, but also on the costs and emissions related to the production of district heating and electricity in the different seasons.
