[Webinar] High temperature heat pumps in energy intensive industries: core components

When: 10:10 - 11:20, Wednesday 07 April 2021

Location: Online

Registration fee: Free

Organizer: EHPA


The objective of the online seminar is to provide an overview of the components used in the open-loop and closed-loop heat pump system.

The open-loop heat pump system developed by the DryFiciency consortium uses advanced, low-cost, turbo-compressor technology originating from the automotive sector. It is further developed to reach condensation temperatures of up to 160°C at a combined pressure ratio of 6 when compressing steam over two stages. In the condenser, the hot excess steam reheats the process steam of the dryer. Thereby, the natural gas burner can be replaced.

Closed-loop heat pump systems, also known as compression heat pumps, compress a working media (so-called refrigerants) to higher temperature levels at the heat consumer (heat sink) than at the heat source. They deliver a much higher amount of energy (heat) than the amount of energy (usually electricity) needed for their operation. Therefore, they are highly efficient waste heat recovery devices.
