Title:
HEAT EXCHANGING VENTILATOR
Document Type and Number:
Japanese Patent JP3039079
Kind Code:
B2
Abstract:
PURPOSE: To reduce in size in a vertical direction and a cost by setting an oblique angle of a supply air inlet surface or an exhaust inlet surface to a bottom plate to a special range, and setting a supply air/exhaust flow rate ratio or exhaust/supply air flow rate ratio to a special range.
CONSTITUTION: A heat exchanging ventilator 10 is a ceiling mounted type mounted on a ceiling plate, and has a casing 11 for constituting the outside of the ventilator 10. The casing 11 has a ceiling plate 11a and a bottom plate 11b which are substantially laterally extended, and a total heat exchanger 12 detachably contained between both. The exchanger 12 is the casing 11 in a state that its supply air inlet surface 12a is provided at a predetermined angle to the plate 11b of the casing 11. The angle is in a range from 13 to 30 degrees, and supply air/exhaust air flow rate ratio is set to a range of 0.9-1. Thus, a height H of the exchanger 12 can be decreased The exchanger 12 can be disposed in a desired size, and a manufacturing cost, a directing cost are reduced.
