CHANGE - Heat Pump System Retrofitting - October 9th 2024

  • Design propane-based heat pumps with GT-SUITE, streamlining processes while keeping current components.

  • Understand how vapor injection compressors can enhance the Coefficient of Performance (COP) of heat pump systems.

  • Gain insights into the potential of propane as a promising alternative for heat pumps, supported by scientific research and breakthroughs in the field.


Abstract
Driven by regulatory requirements, alternatives to classic refrigerants must be found. Propane is a promising alternative for running a heat pump. This can be seen, among other things, in the fact that at the beginning of this year the European scientific community spoke out in favour of propane in a position paper, as well as last year's breakthrough by the Frauenhofer Institute to develop a propane-based heat pump with a load of less than 150g and a heat output of 12.8kW.
In the first step in this webinar, a heat pump with propane is presented as designed using GT-SUITE, based on an existing system with R410A. An attempt is made to preserve the majority of the existing components.
 
Vapor injection compressors are used in heat pump system with high-pressure ratios and extended ambient conditions to increase the COP of the system and reduce the operating costs. In the second part of this webinar, a holistic system optimization methodology is used, in which the optimal geometric position of the steam injection is determined. This means that possible dynamic system and compressor interactions are taken into account.
 

Topics include: 

• Regulatory requirements are driving the search for alternatives to traditional refrigerants
• Propane is a promising alternative for heat pumps, supported by European scientific community
• This webinar presents a heat pump using propane designed in GT-SUITE, aiming to retain existing components
• A holistic system optimization methodology is employed to determine the optimal geometric position of steam injection, considering dynamic system and compressor interactions
