Abstract

The invention can be used for final air adjustment in the room itself. The purpose of the invention is to increase efficiency and simplify the design of the air conditioner closer. The supply air pipe 3 communicates with the primary air chamber 2 in the center of the bottom wall of the latter. The air distributor 4 is placed in the chamber 2 and is made in the form of a perforated convex plate, oriented convex toward the panel 5 with ejection nozzles 6. The density of the perforations on the plate increases in all directions from its center. The supply and secondary air are mixed in chamber 8. The mixture temperature is maintained in the heat exchanger 7 at the desired level due to the treatment of secondary air. 2 Il.

Phi.1

The invention relates to air conditioning technology and can be used in the manufacture of equipment for final air conditioning in the room itself.

The purpose of the invention is to increase the efficiency and simplify the design of the ejection-closer.

Figure 1 presents the ejection conditioner-closer, General view; figure 2 - section aa in figure 1.

The ejection air conditioner 1 comprises a primary air chamber 2, a supply air inlet 3 communicated with it, an air distributor 4 placed in chamber 2, a panel 5 with ejection nozzles 6, a heat exchanger 7 and a mixing chamber 8.

Air inlet 3

communicated with the primary air chamber 2 in the center of the bottom wall 9, and the air distributor 4 is designed as a perforation of a different convex plate with an oriented convexity in the side of the panel 5 with ejection nozzles 6.

The perforation density on the plate increases in all directions from its center.

Ejection air conditioner closer 1 works as follows.

Primary air pre-treated in the central air conditioner (not shown) enters the supply air inlet 3 of the ejection air conditioner-closer 1. The intake air enters the primary air chamber 2 in which the air distributor 4 is located.

Due to the fact that the air distributor 4 is made in the form of a perforated convex plate, oriented convex toward the panel 5 with ejection nozzles 6, and also because the perforation density on the plate increases in all directions from the center of the plate

increases with distance from the center of the plate. This ensures that the air flow is distributed evenly over the entire area of the plate, which ensures an even supply of air to the ejection nozzles 6 on the panel.

The passage through the ejection nozzles 6, the air enters the mixing chamber 8, where the secondary air from the room is ejected (not shown). The secondary air passes through a heat exchanger 7, in which it is either heated or cooled.

The uniform distribution of air through the ejection nozzles 6 increases the efficiency of the ejection conditioner-closer 1, since each ejection nozzle 6 is uniformly loaded and creates the maximum vacuum for secondary air leaks.

In the mixing chamber 8, the intake and secondary air are mixed, while the temperature of the mixture is maintained at the desired level due to the treatment of secondary air in the heat exchanger 7. Then the treated air is supplied to the room.
