3 Claims;
is invention relates to methods of and apparatusjfor distributing air in spaces to which air is supplied at difierent conditions of temperature and humidity to compensate for Variations in outv door and indoor load lactors.
The principal object of the invention is to provide a simple and inexpensiveair outlet designed effectively and preferably automatically to distribute heated orcooled air to diirerent zone of an enclosure to be conditioned, so that predetermined conditions may be maintainedin the zone of occupancy despite variations in the character of the air supplied at the .point of discharge from the outlet. g A feature of the invention resides in'the provision of an outlet arrangement in combination with a duct wherein is located a sensitive element so that a series of dampers at the discharge end of the outlet will direct air toward the ceiling level or toward the floor level or toward intermediate levels depending upon the character of the air affecting the element.
Otherobjects and .features af ording advantages in air distribution, especially in large areas where industrial operations are performed, and where large ceiling heights are required, will be more apparent from the following description of a typical, adaptation of the invention, to be read in connection with, the accompanying drawings, inwhich:
Fig. is adiagrammatie representation of anplicants outlet arrangement positioned in combination with a duct section, the'arrangement 'being. capable of adjustment manually or automatically.
' Fig. 2 is a showing of applicants outlet arrangement under intermediate. season conditions when the outlet is arranged, either manually or automatically, to distribute air in intermediate zones between floor and ceiling levels.
Fig. 3 is a showing of applicant's outlet arrangement under winter operating conditions when air, at relatively high temperatures, is discharged substantially downwardly toward the floor level; and
Fig. 4 is a showing of applicantsoutlet arrangement, under summer operating conditions, when air, at relatively low temperatures, is discharged substantially horizontally at the ceiling level. Considering the drawings, similar designations referring to similar parts, numeral 5 is a supply duct to which air is routed by a fan, not shown,
system. 'Duct5 maybe of any desired material, and of required size, serving any desired area.
Normally, the duct will have a plurality of outlet connections such, as 6; These outlets are stag-- gered within a large area, arranged at the ceiling level of the area, to supply air at designated points in the area.
In Figs. 2, 3 and 4 broken line i designates the ceiling level of an enclosure and broken line 8 designates the top of a supporting member such as a beam or the like upon which duct 5 is positioned. Y
Within duct 5, at any suitable point, on the downstream side from the fan serving duct 5, is locatedone or more sensitive elements 9. Forexample, in the arrangement illustrated in the drawings, 9 designate the thermostatic bulb. Element 9 maybe located in one point of duct 5 or may belocated at one or more of the outlet connections 6, dependin upon whether it is desired to gauge the temperature of the air at one point or atvarious of the outlets.
At each outlet connection is provided a damper motor In. This may be a damper motorof the plunger piston type made by the Johnson Service Company. Damper motor 1-0 is operated by compressed air admitted from ausual source through inlet I I. Thermostat 9 is arranged to control the admission of compressed air to the damper motor which may be of the normally closed type, so that an increase in pressure causes the piston to advance downwardly. A thermostatic control for this purpose is shown, for example, in Otto Patout No, 1 ,897,857. I
As best shown in Fig. 1, piston I2 is suitably connected by coupling I3 to a plunger rod l4. Plunger rod l4 slides within sleeve holding member t5 which is fixed in position by stayrodsl6, which in turn are connected to the sides of'outlet 6. Plunger rod l4 has a pin I! which rides within slot 18 of sleeve-member 15. Slide pieces 19 are suitably attached to and ride up and down with the pin ll responsive to the movement of the plunger rod. Pivot member 20 is affixed to member [5 and atits pivot points 2| are linked intermediate damper members 22. Outer damper members 23 are pivoted to the outlet 6 at pivot points 24. Pivot points 24 are located at the bottom extremities of outlet 6. As may be observed, upon a movement of the slide pieces up and down, the Various links 25, pivotally attached, as shown, to the slide pieces and damper members, will cause the damper members to assume the various positions illustrated in Figs. 2, 3 and 4.
If desired, the actuation of the rod [4 can the dampers will assume an intermeditae position as shown in Fig. 2. On the other hand, under winter operating conditions, when it is desired to direct the air downwardly toward the floor, espe.. cially in factory areas having relatively great ceiling heights, the thermostat will reflect the relatively heated condition of the air and cause the damper motor to actuate the plunger rod so that the dampers will assume the position shown in Fig. 3. Under summer operating conditions, the thermostat will reflect the relative cool condition of the air supplied by the fan and accordingly cause the damper motor t actuate the plunger rod so that the dampers will assume a position as shown in Fig. 4 with the air discharged substantially horizontally at the ceiling level.
It will be apparent that various modifications of the invention may be employed, including variations in types of air discharge elements and operation of controls, and applicant makes no limitation with respect to the scope of application and method of carrying out the invention as claimed.
I claim:
1. A combination of elements for distributing conditioned air having wide variations in temperature, comprising a supply duct positioned above the ceiling level of the area to be conditioned, an outlet at the ceiling level connecting with said supply duct, a plurality of adjustable vanes, the outer vanes being pivoted at their upper ends to the lower edge of the outlet, the intermediate vanes being pivoted intermediate their ends and being of sufficient length to overlap the outer vanes when their lower ends are moved outwardly to direct air in a substantially horizontal direction, mean for supporting said vanes including'a sleeve, means for supporting the sleeve, a pivot member attached to said sleeve, the intermediate vanes being pivoted on said pivot member, a control member adapted to slide within said sleeve, slide members adapted to be moved by movement of said control member, and link mechanism connecting said slide members to the vanes, means including a power element positioned above the supply duct for actuating said control member, and a control element for governing the operation of the power element, said control element being positioned in the path of air passing through the supply duct, movement of said control member actuating the link mechanism to dispose said vanes in such manner that air discharged from the duct will flow, under summer operating conditions. in a direction along and substantially parallel with the ceiling of the area and, under winteroperating conditions, will be directed toward the floor level of the area.
2. In combination for distributing cooled air in the summer and heated air in the winter within an area to'be conditioned, an air distributing duct positioned on top of a ceiling supporting member, an outlet connection leading from the duct and terminating at the ceiling level, a plurality of vanes, the outer vanes being pivoted at their upper ends to the lower edge of the outlet, the intermediate vanes being pivoted intermediate their ends and being of sufficient length to overlap the outer vanes when the lower ends are moved outwardly to direct air in a substantially horizontal direction, means for supporting said vanes including a sleeve, means for supporting the sleeve, a pivot member attached to said sleeve, the intermediate vanes being pivoted on said pivot member, a control member adapted to slide within the sleeve, slide members adapted to be moved by movement of said control member, and link mechanism connecting said slide members to the vanes, a power element positioned on top of the duct for actuating said control member, and a control element positioned in the path of air flowing to the outlet connection, said control element controlling the action of the power element, movement of said control member by said power element actuating the link mechanism to dispose the vanes in position to discharge cooled air substantially in a horizontal direction along the ceiling under summer conditions and in position to discharge heated air substantially vertically toward the floor under winter conditions.
