A mechanical ventilation system, often employing a heat recovery or energy recovery core, introduces fresh outdoor air into a building while simultaneously exhausting stale indoor air. Its operation during warmer months aims to improve indoor air quality and manage humidity levels. For instance, it can expel moisture-laden air created by showering or cooking, replacing it with drier air from outside, thereby reducing the potential for mold growth.
The advantages of operating such a system in the summer include enhanced comfort, mitigation of allergens and pollutants, and, in some cases, reduced energy consumption. Historically, natural ventilation was the primary method of introducing fresh air. However, in tightly sealed modern buildings, mechanical systems are necessary to ensure adequate air exchange. Employing one during the summer months combats issues like stagnant air and elevated indoor humidity, creating a healthier and more comfortable indoor environment. This is especially crucial in climates with high humidity levels.
