HIGH-CAPACITY HEAT PUMPS in large-scale buildings, industry, power plants and process technology HEAT PUMPS

Economic, ecological and ethically convincing »» RESPONSIBILITY I ncreasing energy costs are presenting industry, commerce, trade and above all local authorities with huge challenges. The energy costs for space heating and air-conditioning or process heat represent by far the highest cost factor. The decision-makers are also being required to save primary energy and to reduce pollutants and CO2 emissions. Renewable energy from ambient warmth or exhaust heat utilisation will in the long run guarantee the supply of energy economically, efficiently and without risk. The new generation of heat pumps...

Due to the savings in energy and operational costs achieved in comparison to conventional heating or cooling systems, the use of high-capacity heat pumps is especially economical and environmentally friendly. A further essential usage potential of heat pump technology for increasing energy efficiency lies in energy and power plant technology as well as in district heating networks. Chemical, mechanical, endogenous and exogenous processes of all kinds can be used as heat sources or heat sinks. Exhaust heat of all kinds from exhaust air, cooling water or heat from waste water can be used meaningfully...

INNOVATIVE TECHNOLOGY Fit for future OCHSNER industrial heat pumps work efficiently and are environmentally friendly, achieving low operating costs, maximum operational safety and longevity. Components of the highest quality, decades of experience and a simple, compact design are the basis for energy efficiency, operational safety and customer satisfaction. During the past years, OCHSNER has continuously re-engineered its high-capacity heat pump series. The aim of this research and development program was especially » » » » » » » » to increase the COP values to increase the flow temperatures...

Energy recuperation from process and exhaust heat in industry, process and power station engineering »» Utilisation of low-temperature exhaust heat (up to 30°C) in order to generate room and process heat (up to 98°C) Low-temperature exhaust heat, which cannot be reutilised using conventional heat exchangers, is available in large quantities, especially as a result of mechanical processes or cooling processes in the chemical, pharmaceutical and food industries. Using heat pumps, this low-temperature exhaust heat can be efficiently brought back up to a useable temperature level. »» The heat pump...
