Waste Heat Recovery with Industrial Heat Pumps

Industrial refrigeration systems reject a significant quantity of waste heat to the atmosphere. Heat pumps can capture this waste heat efficiently and use it to reduce the fossil fuels consumed to heat water.  Industrial heat pumps are environmentally friendly and economical, allowing end-users to make the most of their energy resources.

Industrial ammonia heat pumps offer end-users a comprehensive sustainable solution by reducing energy consumption, water, waste water, CO2 emissions and operating costs. They are environmentally friendly as ammonia is a natural refrigerant with an ozone depletion potential (ODP) of zero and a global warming potential (GWP) of zero.

Industrial heat pumps provide energy conservation, by converting the heat energy removed by ammonia refrigeration systems and transforming it into beneficial heat for use in satisfying plant hot water requirements. This source of energy is renewable as the heat is naturally occurring within food products and is made available through food preservation by the process of refrigeration, a reusable energy source.

Ammonia heat pumps reduce operating costs.  Ammonia refrigeration systems absorb heat from products, processes, equipment, people, building heat gains and infiltration, and then reject it as waste heat to the atmosphere through, typically, evaporative condensers.  The majority of the heat delivered by heat pumps comes from the heat extracted from these cooling loads. An incremental amount of heat delivered by heat pumps comes from the electric energy consumed in converting the low grade waste heat into high temperature useable heat.

An additional benefit of industrial heat pumps, applied as retrofits to existing systems, is that they add condensing capacity to systems.  Industrial heat pumps divert load away from evaporative condensers, allowing existing system compressors to operate more efficiently at lower condensing pressures.  Further, reduced condenser loads correspond to conservation of water, water treatment chemicals, and waste water.
