Compact Thermal Energy Storage


Demand for RE-based, energy-efficient cooling systems is rising from export markets.

Idea for solution

PURIX is a Danish manufacturer of refrigeration and air conditioning systems based on natural refrigerants and the use of thermally renewable energy instead of electricity. The innovation project will develop a market-mature compact and attractive energy storage based on a PURIX Plug & Play Solar Cooling and Instant District Cooling System. That is, a new absorption heat pump, which is based on solar energy; a storage of energy in switching materials (PCM) to provide cooling in times without sun.

Project deliveries

  • Storage tank with bulk PCM (phase change material)
  • New product solution that does not exist in the global market for energy storage for cooling
  • Increased competitiveness of Solar Cooling and Instant District Cooling per. kW
