PCM Heat Batteries

Phase change material (PCM) is a substance that, by melting and freezing at a certain temperature, can store and release a large amount of heat at that temperature.

Ice (phase change at 0°C) Hand warmer (melts at 58°C)

Sensible Heat Versus Latent Heat, example with Sodium Acetate

Sunamp Heat Batteries

• PCM temperature can be adapted to service, region, economics;

• Heat Batteries are used to:

1. Maximise COP of heat pump

2. Maximise self-consumption of renewables

3. Maximise comfort to user

4. Minimise energy bills

5. Minimise installation and maintainance cost

6. Install storage where no water tank would fit

Thank you for your attention!
