soojustagastust

Soojustagastust, also known as heat recovery, refers to the process of capturing waste heat from one stream or process and transferring it to another stream or process to preheat it. This is a common energy-saving technique used in various industrial and residential applications. The primary goal of soojustagastust is to reduce overall energy consumption by minimizing the need to generate heat from primary sources.

The basic principle involves a heat exchanger, which allows thermal energy to move between two mediums without them coming into direct contact. For example, in a ventilation system, warm exhaust air can be used to preheat incoming fresh air. This reduces the load on the heating system for the building. In industrial settings, waste heat from exhaust gases, cooling water, or other processes can be utilized to preheat boiler feedwater, process air, or other materials.

Soojustagastust systems can vary in complexity, from simple air-to-air heat exchangers to more sophisticated systems involving heat pipes or thermal fluids. The efficiency of a soojustagastust system depends on factors such as the temperature difference between the two streams, the type of heat exchanger used, and the flow rates. Implementing soojustagastust can lead to significant reductions in fuel costs and greenhouse gas emissions, making it an important component of sustainable energy management.
