Areas of application
The following exemplary general conditions give an impression of the different application possibilities, whereby all values in between are naturally possible. These are guide values that are achieved in practice. The exact data is dependent on the specific application.
|Sink in (°C)||95||115||60||65||120||90||70|
|Sink out (°C)||120||140||90||85||140||105||95|
|Source in (°C)||80||100||70||60||110||80||65|
|Source out (°C)||60||80||45||45||95||70||45|
The requirements for integration are low, and the installation costs are usually lower than for conventional heat pumps.
Local and district heating
Here, the integration is typically quite easy, because there is already a water circuit that can be used either directly or integrated via heat exchangers.
For this type of application, a COP that is up to 100% higher compared to conventional heat pumps can be expected.
Exemplary characteristic numbers for district heating use
|Sink in (°C) (district heating return)||60|
|Sink out (°C) (district heating supply)||98|
|Source in (°C) (air from flue gas condenser)||60|
|Source out (°C) (waste gas)||30|
Industrial drying and cooling processes
Drying often requires different temperatures throughout the process. The RHP can continuously adjust the temperature electronically controlled.
Exemplary characteristic numbers for industrial drying processes
|Sink in (°C) (ambient air)||10-35|
|Sink out (°C) (air for drying process)||40-60|
|Source in (°C) (ambient air)||10-35|
|Source out (°C) (air for cooling in the process)||0-5|
|COP (dependent on the exact temperature combinations)
One particularly advantageous application is when hot water is required in the production process (e.g. in the chemical industry). In this case, cooling water can be used as a source, and the hot water can be provided for the production process. This is a very efficient application in a temperature range that cannot be achieved by conventional heat pumps.
Instead of generating heat and cold separately, a rotation heat pump can also be used.
Exemplary characteristic numbers for a high-temperature application
|Sink in (°C) (hot water from production – return)||90|
|Sink out (°C) hot water for production – supply)||120|
|Source in (°C) (cooling water – return)||80|
|Source out(°C) (cooling water – supply)||55|
