How Mechanical Heat Recovery Unit Works: A Step-By-Step Explanation

A Mechanical Heat Recovery Unit (HRU) is a sophisticated system designed to optimize energy efficiency by recovering heat from outgoing air streams and transferring it to incoming air streams. Here’s a step-by-step explanation of how it works:

• Air Intake:The process begins with the HRU drawing in fresh air from the environment, which serves as the incoming air stream. This air may be from outside or from spaces within a building.
• Outgoing Air Stream:Simultaneously, the HRU extracts air from the inside of a building or space, forming the outgoing air stream. This air is usually warmer due to heating systems, human activity, or electronic equipment.
• Heat Exchange:Within the HRU, the incoming and outgoing air streams are directed through separate channels but pass closely together in a heat exchanger. This heat exchanger is typically made of materials with high thermal conductivity, such as aluminium or copper.
• Transfer of Thermal Energy:As the warm, outgoing air and the cooler incoming airflow through the heat exchanger, thermal energy (heat) transfers from the outgoing air to the incoming air. This transfer occurs without the two air streams mixing, thanks to the design of the HRU.

Mechanical Ventilation Heat Recovery Systems

Mechanical Ventilation Heat Recovery Systems (MVHR) are innovative solutions designed to enhance indoor air quality while conserving energy in residential, commercial, and industrial buildings. These systems function through a series of interconnected processes that recover heat from outgoing stale air and transfer it to incoming fresh air.

The operation begins with the MVHR system drawing in outdoor air and extracting indoor air through separate ducts. These air streams are then directed through a highly efficient heat exchanger where thermal energy from the outgoing air is transferred to the incoming air without the two streams mixing. This process pre-heats or pre-cools the incoming fresh air, depending on the season, reducing the workload on heating or cooling systems.

The now-conditioned air is distributed throughout the building, ensuring a comfortable and healthy indoor environment. MVHR systems are equipped with filters to remove pollutants and allergens from the incoming air, enhancing indoor air quality. By significantly reducing the building’s energy demand for heating and cooling, MVHR systems contribute to lower utility bills and a reduced carbon footprint, making them an integral component of sustainable building design and construction. Key considerations for designing and implementing MHR systems
