1223 results about "Natural ventilation" patented technology

Natural ventilation is the process of supplying air to and removing air from an indoor space without using mechanical systems. It refers to the flow of external air to an indoor space as a result of pressure differences arising from natural forces. There are two types of natural ventilation occurring in buildings: wind driven ventilation and buoyancy-driven ventilation. Wind driven ventilation arises from the different pressures created by wind around a building or structure, and openings being formed on the perimeter which then permit flow through the building. Buoyancy-driven ventilation occurs as a result of the directional buoyancy force that results from temperature differences between the interior and exterior. Since the internal heat gains which create temperature differences between the interior and exterior are created by natural processes, including the heat from people, and wind effects are variable, naturally ventilated buildings are sometimes called "breathing buildings".

Energy Efficient House Ventilation

A method and apparatus for maintaining an acceptable level of outside air exchange rate in a structure. The natural ventilation rate is determined as a function of the outdoor air temperature, and the amount of mechanically induced ventilation that is used to supplement the natural air ventilation is controlled such that the sum of the natural occurring ventilation and the mechanically induced ventilation is maintained by a substantially constant predetermined level. One approach is to use a stepper motor to modulate the position of the damper, while another approach is to use an on / off motor damper and to close the damper at outdoor temperatures below a threshold level and to otherwise leave the damper open and use the regular on / off cycle of the system blower to control the flow of outdoor air, with provision for allowing the fan to remain on for a calculated period of time after the system is cycled off to thereby maintain the desired level of ventilation. Can also vary the speed of the furnace blower or a separate ventilation fan motor.
