Here'S a Simple and Inexpensive Way to Get Automatic House Ventilation

摘要

A simple and inexpensive automatic ventilator, easily installed in most Canadian houses, could help greatly to reduce the excessive humidity and condensation which occurs in winter. The ventilator is suitable for any house with a forced warm-air furnace and consists only of a simple duct, equipped with a convenient and easily adjustable damper, running from outside the house to the cold air return plenum of the furnace. This ventilator can automatically supply a regular flow of heated, fresh, outdoor air to all parts of the house. Such ventilators are by no means unusual, and are commonly used in some parts of the Prairie Provinces. (Author)
