Heat Recovery Used in a Wide Range of Applications

Heat Recovery is an energy recovery technology that reduces energy consumption and increases energy efficiency by capturing and reusing waste heat in industrial processes or buildings. This technology is used in many applications, including industrial production, building heating, air conditioning and hot water systems.

Industrial applications

In industry, heat recovery is commonly used for the following purposes:

Process heat recovery: High-temperature waste heat generated during industrial production can be used to heat other fluids or provide thermal energy, such as heating water or steam. This waste heat recovery can be used to improve the energy efficiency of production processes and reduce energy consumption and production costs.

Hot Air Recovery: Hot air generated in industrial processes can be captured and used to heat buildings or heated spaces, thus reducing reliance on conventional heating systems and saving energy costs.

Waste heat to power: Generating electricity from waste heat generated in industrial processes, for example using the heat from stack exhaust gases to drive a steam turbine generator to produce electricity. This method converts waste heat into renewable energy and provides an additional source of electricity.

Building applications

In the building sector, heat recovery is mainly used in heating, ventilation and air conditioning (HVAC) systems to reduce energy consumption and improve indoor air quality. Common heat recovery technologies include:

Heat exchangers: Heat energy from indoor air is captured through heat exchangers and used to preheat incoming outside air. This technology is known as air-to-air heat exchange and can reduce energy consumption in heating and air conditioning systems.

Exhaust air heat recovery: Hot air from the building is passed through a heat exchanger to the incoming outside air to preheat the fresh air entering the building. This technology can be used in heating and ventilation systems and to improve indoor air quality.

Wastewater heat recovery: Heat energy from wastewater generated in a building, for example from bath water or kitchen drainage, is utilised and transferred to the water supply system through a heat exchanger for heating fresh water. This technology is known as wastewater heat recovery and can save on hot water heating costs.

The application of heat recovery technology can effectively reduce energy consumption, lower carbon emissions and save energy costs. In the context of sustainable development and energy conservation, heat recovery technology will be more widely applied and promoted in the future.
