What is an ERV Core?
An ERV Core is a mechanical component that safely and efficiently compensates for temperature differences between two fluids.
It is a component that equalizes temperatures without directly mixing liquids or gases, allowing heat to pass through metal plates and thin tubes. It functions as a core component in heat exchangers and other devices. It is incorporated into many machines, such as water heaters and automobile radiators.
The basic structure is based on the principle of increasing the surface area by expanding the path where fluids come into contact. This is achieved by stacking thin metal plates or engraving microscopic grooves to expand the contact surface. Copper and aluminum, which have high thermal conductivity, are the main materials used, but there are also many ceramic products that are resistant to corrosion and freezing. Resin products made with precision processing are also available, and optimization for each application is progressing. Total heat exchange rate and sensible heat efficiency are used as indicators of efficiency, and the higher the rate, the less energy is required for heat exchange.
Applications of ERV Cores
ERV cores are used in the following applications.
1. Industry
ERV cores are used for various purposes in large-scale facilities such as factories. They are used in manufacturing lines to cool machinery and equipment so that they always operate at the appropriate temperature, or conversely, to heat products. In power plants and chemical plants, they are used to recover the enormous amount of heat generated during the process, thereby improving the energy efficiency of the entire plant.
2. Air conditioning equipment
ERV cores play an important role in air conditioning equipment such as air conditioners and ventilation systems. For example, they are used to replace the air while maintaining a comfortable temperature in the room during ventilation. They contribute to reducing the burden on cooling and heating and maintaining a comfortable space with less energy.
3. Hot water supply and heating equipment
ERV cores are also used inside water heaters and heating equipment. When boiling water, the high heat generated by gas combustion must be efficiently transferred to the water. By passing the heat through the ERV Core, it can be transferred to the water without waste, making it possible to boil water in a short time. In addition, since there is still heat remaining in the exhaust gas, it is also used in heat recovery devices to reuse that heat. This technology is essential for making the most of limited energy and supporting our comfortable lifestyles.
