Industrial Heat pump process
Industrial heat pumps actively recover waste heat. The system is rather simple: heat pumps increase the temperature of waste heat streams to a higher temperature, making those streams usable again.
Heat pumps can find application in numerous industrial processes and are particularly efficient when direct heat exchange is not possible, going even beyond a closed circuit and allowing the creation of an integrated system with different processes or users.
The process:
The heat pump operates on the basis of a thermodynamic cycle (Carnot cycle) with a working fluid (refrigerant) which changes state (liquid/gas) in a continuous cycle
At low temperature the refrigerant absorbs heat (at the source) through a heat exchanger, then it is compressed and delivers heat at a high temperature (at the sink) through a heat exchanger.
Unique for Heaten's piston compressor
-
Flexible
Largest flexibility regarding temperatures and load range. Easy to optimize based on operating temperatures. Different cylinder versions enable adaptations to each application.
-
Working Fluids
Fully free to choose from a range of working fluids. Independent from compressor design (versus e.g. turbo, piston is the only technology that can have a variable compression ratio). Design allows to use different HFO's and HC's with a low Global Warming Potential (GWP).
-
Efficiency
Efficiency curve is almost “flat” over 20 – 100% load range. Technology platform is already designed and tested for 215°C. Piston machines typically have mechanical efficiencies higher than 90%.
-
Durability
Heavy-Duty building on technology which is used to much higher temperatures. Heavy duty design to deliver 80,000 hours runtime between major overhauls. Heaten IP key to durability of high viscosity oil through separation of refrigerant and lubricants.
-
Serviceability
A piston compressor is a globally known technology. Access to qualified service and maintenance personnel in ubiquitous.
-
Scalability
Heaten's compressor uses similar components compared to a Heavy-Duty combustion engine. This guarantees fast production scalability at low costs.
