Features

Innovative Ice Energy Technology

Uses the latent heat of water during freezing Captures and stores thermal energy naturally Converts environmental energy into usable heating and cooling Nearly maintenance-free operation

Four Renewable Energy Sources Combined

The system simultaneously utilizes energy from: Ambient air Solar radiation Precipitation Ground energy This combination maximizes heat source availability and improves overall system efficiency.

Crystallization Energy Utilization

Heat is extracted from water through a phase change process Energy is released when water freezes into ice One litre of freezing water releases a significant amount of usable thermal energy The process can be repeated continuously through regeneration cycles

Efficient Heat Pump Integration

Designed as an optimal heat source for brine-to-water heat pumps Supports monovalent heating operation Enables highly efficient low-carbon heating Improves seasonal performance of the heat pump system

Sustainable Cooling Solution

Stored ice can be used as a cooling source during summer Enables natural cooling with very low energy consumption Reduces the need for mechanical cooling equipment Enhances occupant comfort in warm weather
