摘要:
A rooftop air conditioner having a variable speed fan and an economizer also includes a control feature for adjusting the minimum damper position in response to the speed of the fan during predetermined conditions in order to maintain a desired volume of fresh air from the economizer.
摘要:
A method of manufacturing a ventilator, comprising the steps of assembling a bottom plate (3) with four side plates (4, 5, 6, 7) of a unit casing (2), installing a passage switching member (36) and first and second spacers (27) in an assembly, installing blowing units (17, 18) and partition members (28, 29), attaching a guide rail (48), laying out electric wiring, inserting heat exchange elements (15, 15) along the guide rail (48), and installing a top plate (8).
摘要:
In a method of ventilating rooms fresh air is introduced into theroom at one or serveral places at floor level by means of diffuse air sypply, and the room air is exhausted at the ceiling level of the room. One or several jets of fresh air (2a, 2b) are blown at high velocity into an induction chamber (4) thereby sucking surrounding air (3) into the induction chamber and becoming mixed therein with the surrounding air sucked into the induction chamber. The mixed air from the induction chamber (4) is introduced essentially horizontally into the room to be ventilated. Into the induction chamber (4) surrounding air is sucked in which consists of air (3) from the room to be ventilated, this air being sucked into the induction chamber from a level in the room which is higher than the level at which the mixed air is introduced into the room. The mixed air is introduced into the room by means of diffuse air supply.
摘要:
An air circulation system for a building or other enclosed space that includes an heating, venting and air conditioning (HVAC) unit and a first air duct connecting the HVAC unit with the interior of the building. The system also includes a second air duct connecting the exterior of the building with its interior. A fan or secondary unit directs and moves air from outside of the building to inside the building when a controller determines via one or more sensors that an outside condition is preferable to a condition inside the building. The system also may be used in vehicles such as in ground-based vehicles including public transports, and in aircraft.
