Panel with indirect evaporative cooling via membrane
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
