Ice energy storage with capillary tube mats technology is a form of thermal energy storage that utilizes the phase change of water to store and release energy. This technology is particularly useful for cooling applications in buildings and industrial processes.

Here’s how it works:

Capillary Tube Mats: These are a network of small-diameter tubes that are installed in the ceiling or walls of a building. These tubes are designed to distribute water evenly across a large surface area. The capillary action of the tubes helps to spread the water uniformly.

Ice Formation: During off-peak hours when energy costs are lower, a chiller system cools water and circulates it through the capillary tube mats. As the water flows through the tubes, it comes into contact with the cooler surrounding environment, causing it to gradually freeze and form a layer of ice on the surface of the mats.

Energy Storage: The ice that forms on the capillary tube mats serves as a thermal energy storage medium. This is because the process of water freezing and melting involves a significant amount of energy exchange, which can be harnessed for cooling purposes later on.

Cooling Cycle: When cooling is needed during peak hours, the circulation of water through the capillary tube mats is reversed. The ice stored in the mats absorbs heat from the surrounding air, effectively cooling the indoor environment. As the ice melts, it absorbs a large amount of heat, providing a sustained cooling effect.

Benefits of Ice Energy Storage with Capillary Tube Mats Technology:

Energy Efficiency: By shifting energy consumption to off-peak hours, this technology helps to reduce overall energy costs and grid demand.

Environmental Impact: It can contribute to a reduction in greenhouse gas emissions, especially if the electricity used during off-peak hours comes from renewable sources.

Space Saving: The installation of capillary tube mats for ice energy storage can be integrated into the building structure, saving space compared to traditional thermal storage systems.

Longer Cooling Periods: Ice energy storage systems can provide cooling for longer durations compared to conventional HVAC systems, especially in regions with high cooling demand.

In summary, ice energy storage with capillary tube mats technology offers an innovative and efficient approach to thermal energy storage, particularly for cooling applications in buildings. Its ability to shift energy consumption, reduce costs, and provide sustainable cooling makes it an attractive option for many industries.

Highly efficient and cost saving cooling for buildings and industrial processes – flexible installation and integration options in existing air conditioning technology

The ICE thermal energy storage, jointly developed by greata, can significantly reduce the energy costs for building air conditioning and industrial processes as a supplementary component for existing cooling technology. Other areas of application are cold networks, emergency cooling systems and thermal energy storage for renewable energy power plants. At the heart of the ice energy storage system are capillary tube mats, which enable a particularly high degree of efficiency and fast reaction behaviour due to the dense arrangement and the large heat transfer surface of the capillary tubes. The installation can be made transportable as a container or underground as a basin below the surface.

Capillary tube mats

  Capillary tube mats , also known as capillary mats or capillary irrigation mats, are commonly used in agriculture for various applications including greenhouse production, hydroponics, and plant propagation. These mats consist of a network of small tubes or fibers that distribute water to plant roots through capillary action, providing a consistent and efficient water supply. In agriculture, capillary tube mats are used in the following ways: 1. Greenhouse production: Capillary mats are used in greenhouse operations to provide irrigation to potted plants and raised beds. The mats are placed under the plant containers or beds, and water is supplied to them, either through a reservoir or an automated irrigation system. The mats distribute the water evenly to the plant roots, ensuring proper hydration without overwatering. 2. Hydroponics: Capillary tube mats are used in hydroponic systems to deliver nutrient-rich water to plant roots. The mats are placed beneath the growing medium, and

What is a capillary tube mats? Will it clog? What if it breaks down?

 What is a capillary tube mats? Will it clog? What if it breaks down? 💥 Capillary tube mats radiation system is a new type of low-temperature hot water radiation heating method, imitating the leaf veins of plants and the capillary structure of the human body 🍀 The composition interval is 10-40mm, and the mesh diameter is 4.3 * 0.8mm 💦 Water is an efficient heat transfer medium with a heat transfer speed 1000 times that of air. The liquid flow velocity in the mesh and human capillaries is the same, both between 0.05 and 0.2m/s Quiet and silent. ‼️ Will capillary capillary tube mats clog? The capillary network will not clog. Unlike underfloor heating pipes, underfloor heating pipes emit high temperature water radiation (50=65 ℃), which is prone to scale blockage. The capillary network is composed of low-temperature water (16-35 ℃), which is far from reaching the scale value The system is equipped with a separate filter valve Replace and clean once a year withou
