soojuspöördemise

Soojuspöördemine refers to the process of heat recovery in various industrial and technical applications. It is a principle that aims to minimize energy waste by capturing heat that would otherwise be dissipated and reusing it for other purposes. This is particularly relevant in systems where there are significant temperature differences between outgoing and incoming streams, or between waste heat sources and areas requiring heating.

The fundamental concept involves heat exchangers, devices designed to efficiently transfer thermal energy from one medium to another without direct mixing. In the context of soojuspöördemine, these exchangers are often rotary types, where a rotating mass absorbs heat from an exhaust stream and then releases it to an incoming fresh air or process stream. This continuous transfer leads to a significant reduction in the energy needed for heating or cooling the incoming medium.

Applications for soojuspöördemine are diverse. In building ventilation systems, heat recovery ventilators (HRVs) or energy recovery ventilators (ERVs) use this principle to pre-condition incoming fresh air using the energy from outgoing stale air, thereby reducing the load on heating and cooling systems. In industrial processes, such as in power plants or manufacturing facilities, soojuspöördemine can be employed to recover waste heat from exhaust gases or cooling water and utilize it for preheating combustion air, generating steam, or other thermal needs. The efficiency of soojuspöördemine systems is a critical factor, and advancements in materials and design continue to improve their performance and expand their applicability.
