ERV Core is a mechanical component that safely and efficiently bridges the temperature difference between two fluids.
ERV Core (Heat Exchange Element) is the core component in a ventilation system that regulates temperature and humidity when exchanging exhaust air and supply air to reduce fluctuations in indoor temperature and humidity and provide a comfortable indoor environment. The basic structure consists of a partition plate that allows temperature and humidity to move back and forth and a spacing plate that forms a flow path. Paper, resin, and metal are commonly used as materials.
Total heat exchange rate and sensible heat efficiency are used as indicators of efficiency, and the higher the efficiency, the better the control of fluctuations in the indoor environment. The higher the efficiency, the lower the fluctuation of the indoor environment, thereby reducing the load on air conditioning equipment and contributing to cost reductions through energy conservation.
ERV Core is used in the following applications
Large ERV Core elements are widely used because of the need for both ventilation and air conditioning in large spaces such as manufacturing plants.
This improves energy efficiency and reduces wasteful energy consumption while improving IAQ (indoor air quality) by exhausting dust, gases, odors, etc. generated at manufacturing sites, and is widely used as a technology to support sustainable production.
Stationary (direct current and counter-current) and rotary types are mainly used to increase the efficiency of heating and cooling and to reduce energy consumption through temperature exchange with outdoor air. This provides a comfortable environment with low operating costs and contributes to reducing environmental impact.
Stationary (direct current and counter-current) and rotary types are mainly used, and are incorporated in various types of evocation systems. These systems efficiently regulate indoor temperatures and exchange temperatures with outdoor air to reduce the burden of heating and cooling, thereby realizing energy conservation.
