Ventilate Your Home
How your home really “Breathes” ?

Why do we need to ventilate?
For centuries homes weren’t ventilated, and they did all right, didn’t they? Why do we need to go to all this effort to ventilate houses today?
“Nowadays Ventilation is too much important for your home to get proper air and sunlight in each room or else it causes serious problems.”
Windows has become the one of the important part of your house, whether you live in an Appartment or house, Now adays every house comes with insulation in the walls, so fresh air could pretty easily enter and keep your home warm in winter and cold in summer, where windows helps you to balanced ventilation with heat recovery.
- Much better ventilation is provided through a balanced system in which separate fans drive both inlet and exhaust airflow. This allows us to control where the fresh air comes from, where that fresh air is delivered, and from where exhaust air is drawn. Balanced ventilation systems can be either point-source or ducted. With ducted systems, it makes sense to deliver fresh air to spaces that are most lived in (living room, bedrooms, etc.) and exhaust indoor air from places where moisture or pollutants are generated (bathrooms, kitchen).
- Balanced ventilation with heat recovery if there are separate fans to introduce fresh air and exhaust indoor air, it makes a lot of sense to locate these fans together and include an air-to-air heat exchanger so that the outgoing house air will precondition the incoming outdoor air. This air-to-air heat exchanger—more commonly referred to today as a heat-recovery ventilator or HRV—is the way to go in colder climates. A slightly different version, known as an energy-recovery ventilator (ERV), is similar but transfers moisture as well as heat from one airstream to the other, keeping more of the desirable humidity in the house in the winter and reducing the amount of humidity introduced from outdoors in the summer.
