lämmönvaraston

Lämmönvarasto refers to a thermal energy storage system used to store heat for later use. These systems are designed to capture surplus heat, often generated during periods of low demand or from renewable sources, and release it when needed to maintain a desired temperature. The primary goal is to improve energy efficiency and reduce reliance on conventional heating methods.

There are several types of lämmönvarasto, each utilizing different methods for storing thermal energy. One common approach involves water-based storage, where large tanks are heated and insulated to retain the heat for extended periods. Another method uses phase change materials (PCMs), which absorb and release heat as they transition between solid and liquid states. Other systems might employ sensible heat storage, where the temperature of a material is raised to store energy, or thermochemical storage, which utilizes reversible chemical reactions.

The implementation of lämmönvarasto systems can be found in various applications, ranging from residential buildings to large industrial complexes and district heating networks. By decoupling heat generation from heat consumption, these storage solutions can help to balance energy supply and demand, leading to cost savings and a reduced environmental footprint. They are particularly beneficial when integrated with intermittent energy sources like solar thermal or waste heat recovery systems. The effectiveness of a lämmönvarasto depends on factors such as storage capacity, insulation quality, and the efficiency of the charging and discharging processes.
