Project Summary

At the heart of PCM-ACStore is the innovative combination of PCM ice gel and solar photovoltaic (PV) panels. PCM ice gel absorbs and releases thermal energy at a constant temperature during its phase change. This allows the system to store excess solar energy and release it as cooling energy when needed. Whether you're using radiant cooling panels or standard fan coils, our system dynamically adjusts to meet your cooling needs with minimal energy consumption.

Our goal is to provide accessible and reliable cooling solutions that enhance resilience in communities affected by extreme heat, ensuring no one is left behind in the transition to sustainable energy.

How PCM-ACStore Works

The heart of the PCM-ACStore system lies in its innovative design:

PV Panels and Supercapacitors: Solar PV panels generate power stored in supercapacitors, ensuring smooth energy supply.

Variable-Speed DC Compressor: Driven by solar energy, the compressor adjusts its speed to match cooling needs, maintaining optimal efficiency.

Natural Refrigerants: A hydrocarbon refrigerant blend is employed, offering an environmentally friendly alternative to traditional refrigerants.

PCM Ice Gel Cooling Storage: The system stores cooling energy in PCM ice gels, releasing it when indoor temperatures rise above desired levels.

Radiator Cooling Panels and Transparent Membrane: These components help maximize the cooling effect while minimising energy loss and eliminating the need for additional humidity control.
