In industry and commerce, the requirements for heating and process heat are highly specific. Heat pumps can very often satisfy these needs. Thanks to their efficiency and short amortization period, they represent an environmentally compatible and economically attractive alternative to conventional heating systems.
I The name GEA Refrigeration Technologies of course indicates company affinity to the production of cooling systems. Our engineers, however, are also accomplished specialists with heat pumps. To be sure, heat pumps and refrigeration systems exploit the same physical principle: and they all consist of the same core components such as compressors and heat exchangers.
A heat pump raises heat from its surroundings – air, ground water, or waste process heat – from a lower temperature level to a higher. A crucial factor in the planning and selection of a heat pump system is the type of intended application. If requirements change from heating to cooling in accordance with the seasons – as is typically the case in office buildings and greenhouses – a reversible heat pump can supplement the conventional heating system in winter, or can even replace it. During the summer, the hydraulic system of a heat pump is reversed to supply cooling instead of heat energy. Ground water or the earth itself can in such cases function to store heat or cold.
Many industrial processes simultaneously demand great heating and cooling duty. This especially applies to the food and beverage industries: for example, dairy operations and the manufacturers of frozen foods. In such applications, the waste heat of a refrigeration system can often be used as heat source for heat pumps – which raise the residual heat to a usable level.
Whatever application may interest your company for a heat pump, it will – when its overall life cycle is considered – amortize quickly by a reduction in energy consumption. And this reduces emissions that affect climate. In addition, emphasis is placed on using natural refrigerants such as ammonia wherever possible.
The field of application for heat pumps is diverse. Two fundamental applications can be distinguished:• Simultanious demand for heat and cold (ready meals, slaughterhouses, dairy plants, etc.) • Seasonal requirements for heat and cold (large buildings, district heating, horticulture in greenhouses, etc.)
