lämpöentalteenotto

Lämpöentalteenotto, often translated as heat recovery, refers to the process of capturing waste heat from one system and transferring it to another system where it can be utilized. This technology is employed across various sectors, including industrial processes, buildings, and transportation, to improve energy efficiency and reduce operational costs.

In industrial settings, heat recovery systems can capture exhaust heat from machinery, furnaces, or chemical reactions. This recovered heat can then be used to preheat incoming raw materials, generate steam, or provide space heating. This significantly reduces the need for primary energy sources like fossil fuels.

In buildings, heat recovery is commonly integrated into ventilation systems. Heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs) exchange heat between outgoing stale air and incoming fresh air. This allows for fresh air circulation without substantial heat loss, especially during colder months, leading to lower heating bills and improved indoor air quality.

The principle behind lämpöentalteenotto involves heat exchangers, devices designed to facilitate the transfer of thermal energy between two or more fluids at different temperatures. These fluids can be liquids, gases, or even solids. Common types of heat exchangers include plate heat exchangers, shell and tube heat exchangers, and air-to-air heat exchangers.

Implementing lämpöentalteenotto offers numerous benefits, including reduced energy consumption, lower greenhouse gas emissions, and enhanced comfort in buildings. It is a key strategy in promoting sustainability and achieving energy conservation goals. The specific application and design of a heat recovery system depend on factors such as the temperature difference, the medium of heat transfer, and the required energy output.
