Mechanical ventilation: improve indoor air quality
Indoor air quality is an essential component of health and well-being. Mechanical Ventilation with Heat Recovery (MVHR) is an effective solution to improve air quality in modern homes, especially in buildings with thermal insulation. In this guide, we will explore the latest technologies for managing humidity and purifying air in residential buildings using MVHR systems like the Turbionaire Trend HRV and the LIRAST 100mm MVHR.
Mechanical Ventilation with Heat Recovery (MVHR) Systems
Mechanical Ventilation with Heat Recovery (MVHR) is one of the most effective methods to improve indoor air quality, particularly in residential buildings with thermal insulation. These systems provide a constant air exchange, expelling moist and polluted air and replacing it with filtered and clean air. There are various types of MVHR systems, including decentralized systems, which are ideal for simple installations without major structural changes.
Using heat exchangers, MVHR helps maintain high energy efficiency in buildings. Essentially, the heat from the extracted air is transferred to the incoming air, reducing the energy required to heat the fresh air.
Turbionaire Trend HRV: Decentralized MVHR Unit with Heat Recovery
The Turbionaire Trend HRV is a decentralized Mechanical Ventilation with Heat Recovery (MVHR) unit, perfect for efficiently improving indoor air quality. This unit features a ceramic heat exchanger capable of recovering up to 90% of heat, enabling optimal energy recovery during ventilation.
It is equipped with 8 speeds and a DC brushless motor that ensures quiet operation and low energy consumption, ranging from 1.2W to 7.2W. Features include a remote control, an adjustable humidity sensor, and a Sleep mode for nighttime operation. The alternating extraction and supply mode expels stale air for 70 seconds and supplies fresh air for another 70 seconds, ensuring a healthy environment at all times.
The Turbionaire Trend HRV is easy to install with a simple 100mm wall opening, making it ideal for renovations or buildings where traditional MVHR systems cannot be installed. It is available for purchase on Amazon.
How Does the Turbionaire Trend HRV Work?
The Turbionaire Trend HRV is designed to provide continuous ventilation with heat recovery. The system uses a ceramic heat exchanger to absorb heat from the outgoing air and transfer it to the incoming air. This process maintains indoor temperature stability, reducing the need to reheat the air and resulting in significant energy savings.
The device operates in alternating cycles of air extraction and supply. During the extraction phase, warm indoor air passes through the heat exchanger, warming it. In the supply phase, fresh air from outside is warmed by the heat exchanger before being introduced indoors. This alternation allows effective ventilation without heat loss, making it ideal for energy-efficient buildings.
LIRAST 100mm MVHR Dual Flow with Heat Recovery
The LIRAST 100mm MVHR Dual Flow is a mechanical ventilation unit offering a dual flow system with heat recovery, ideal for ensuring air quality in residential spaces. This model features a switch for selecting between two speed modes, providing a ventilation capacity of 20 m3/h or 24 m3/h.
With its ceramic heat recovery unit, the LIRAST MVHR retains much of the thermal energy during air exchange, ensuring comfort and energy savings. The unit also includes filters on both sides of the heat exchanger to ensure incoming air is free from impurities. Its 100mm diameter makes this model compact and easy to install, perfect for bathrooms, kitchens, and other spaces prone to humidity issues.
The LIRAST 100mm MVHR is available on Amazon and is an excellent choice to improve air quality without complex installations.
How Does the LIRAST 100mm MVHR Dual Flow Work?
The LIRAST MVHR Dual Flow system uses a ceramic heat recovery unit to ensure effective ventilation with minimal energy waste. Fresh air is drawn from outside and passes through the heat exchanger, where it is preheated using the thermal energy of the expelled indoor air. This process maintains indoor comfort while reducing the need for additional heating or cooling.
The device is designed for continuous and quiet operation, making it suitable for spaces like bedrooms and living rooms. Filters on both sides of the heat exchanger ensure incoming air is always clean, removing dust, pollen, and other impurities.
Tips for Improving Indoor Air Quality with Mechanical Ventilation
- Regular Ventilation: Even without an MVHR system, ensure daily air exchange by opening windows and doors for a few minutes each day.
- Humidity Control: Keep humidity levels between 40% and 60% to prevent mold and allergen growth. Use a hygrometer to monitor levels consistently.
- Indoor Plants: Certain plants, such as Snake Plant and Ficus, can absorb pollutants and naturally improve air quality.
