Development of ultra-high temperature hybrid heat pump for process application
Project start March 1st 2012. Ended ultimo 2016.
Purpose of project
The hybrid heat pump utilizes the natural refrigerants ammonia and water as working fluids.Partners in the consortium are the only supplier of this type of systems having max temperatures of 110°C due limitation of standard equipment. New commercial compressors make it possible to reach180-250 °C. Replacement of fossil fuels in thermal processes is then possible.
The project will demonstrate that it is possible to develop an efficient and reliable heat pump process for high temperatures above 180-250°C.
The aim of the project is to increase the operating limits of the hybrid process by using the new standard components that are approved to higher pressures. By using new components the maximum temperatures can be as high as 180-250°C. This will open new markets in the food and process industry for utilizing heat pumps to recover waste energy at a lower temperature level and bring the energy back into processes at a higher temperature level. Nearly 100% of these processes are today heated using fossil fuels.
The project is divided into 7 work packages:
Knowledge collection and literature study
Design and calculation of lab scale pilot plant
Buildup and commissioning of lab scale pilot plant
Measurement, data acquisition and optimization
System integration of full scale ultra-high temperature heat pump
