Background

According to the International Energy Agency (IEA), the power used for running air conditioners and fans accounts for nearly 20% of the total electricity used in buildings or 10% of all global electricity consumption. In the years to come, the use of air conditioners is expected to undergo significant growth. An IEA report predicts a 300% increase in energy consumption related to air-conditioning by the year 2050. This will be driven by an income rise in the world’s hotter regions as well as global warming

Technology Overview

The climate module is charged during night using cold outside air to solidify the Phase Change Material (PCM). Figure 1. First protype of climate module with Phase Change Material (PCM) . Figure 2. Climate Module with PCM filled containers. The module can then provide cool air during the hot day. A unique patent pending design offers a rare combination of low pressure drop and efficient heat exchange during the entire phase change cycle. Figure 3. Integration with existing HVAC system. The module:

is based on an installation of 4x125 kg PCM for an office building of 200 m2. The PCM undergoes 250 full cycles per year.
has installation costs of such a system will be around EUR 15.000. The costs of one kWhr is assumed to 0,8 EUR
has a system will replace/support a conventional A/C system with a COP of 2,5.
has a PCM system will reduce the electricity costs with around EUR 2000 per year. Lifetime of the system is high; +25 years

Stage of Development

A fully functional prototype has been built and tested. Figure 4. Rendering of climate module. Results were very promising. Next step will be to optimize PCM container design and reduce manufacturing costs. A larger 2nd prototype will be developed with focus on autonomous operation with help from various sensors and internal computer.

Prototype is tested and verified.
