Panel with indirect evaporative cooling via membrane

INNO-KOM

01/2023 - 06/2025

Dipl.-Ing. (FH) Hannes Rosenbaum

+49-351-4081-5324

Natural Cooling Panel

Development of a decentralised cooling panel with outdoor air connection, without refrigerant, without humidity input into the room air, retrofittable and with coefficients of performance (COP) > 10

Motivation

  • GWP = 0; COP > 10; 100% renewable energy
  • Decentralised indirect evaporative cooling with no moisture in the indoor or outdoor air
  • Self-sufficient operation, rainwater harvesting
  • Radiant and convective air discharge

Project Objective

  • Application of regenerative and sustainable cooling via evaporative cooling in a decentralised air conditioning system (COP > 10)
  • Functional combination of evaporative cooling and supply of purified outdoor air
  • Novel membrane heat exchanger for two air streams and evaporation water including numerical calculation model
  • Novel convection and radiation efficient air outlet for minimum draught risk
  • Modular, cascadable unit concept for on-demand performance and off-grid and CO2-neutral operation (for PV power supply)
  • Ceiling-mounted, wall-mounted or free-standing cooling panels for residential and non-residential buildings, retrofittable and acoustically compliant

Solution Approach

  • Development of a membrane heat exchanger based on 4-layer textile laminates
  • Development of equipment based on supply air recirculation and exhaust air humidification processes
  • Development of an air outlet for convection and radiation cooling performance
  • MSR and system components for rainwater harvesting, site-independence and cascading
