Abstract

PURPOSE:To permit to obtain uniform flow amount of air from respective ports and improve room cooling and heating effect by a method wherein a grille, provided with a suction port and a blow-off port which are communicated with one of flow paths in the main frame of the air conditioner and the other blow- off port and suction port which are communicated with the other one of the flow paths and neighboring to said suction port and blow-off port, is provided in this device. CONSTITUTION:When a fan coil unit is operated, air inflows from the suction port 18, passes through a heat exchanger 21 through a fan 20 and is blown into a room through the blow-off port 19 as cool or warm airflow, in one side of the main frame 15. A relation between said blow-off pot 19 and suction port 18 becomes reverse in the other side of the main frame 15 and the heat exchanger 21a is located at a position of the suction side of the fan 23. In this case, air, entered through the suction port 19a, is passed through the heat exchanger 21a by the fan 23 and is blown off into the room through the blow-off port 18a as cool or warm airflow. Thus, a distance from the suction port to the blow-off port of the grille is short and air resistance is small, therefore, blow-off speed from the grille becomes high and air speed distribution in the room is improved whereby comfortable room cooling and heating effect may be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to the construction of a ceiling-embedded air conditioner.

Conventional configurations and their problems Conventionally, in older buildings and other facilities, two-way air conditioners, such as fan coil units, that are buried in the ceiling have the configuration shown in Figure 1. It has become.

1 is the main body of the fan coil unit installed on the back side of the ceiling surface 2, 3 is the suction [-14] with respect to the main body 1, and on both sides,
Two-way blowout type blowout IJs 5 and 6 are provided, a grill is used as a set plate, 7 is a blower installed above inside the main body 1, 8 is a heat exchanger, and 9 is air that has passed through the heat exchanger 8. However, the air blown out to the air outlet 6 and the air blown out from the air outlet 6
This is a blowing chamber that serves as a flow path for air that is blown out. 10 is a suction chamber that communicates from the suction port 4 to the air blower pA7. That is, the suction chamber/par 10 is located at the center when the grille 3 is viewed from below, and the Suita chamber 9 is configured on both sides (front and back in the figure) of the suction chamber 10, 5 and 6 are connected.

Since L is constructed in this way, suction is drawn from the suction port 4, and the blower 7. Part of the air that has passed through the heat exchanger 8 flows to the outlet 6 as shown by the arrow, and the rest flows to the outlet 6 via the outlet chamber 9. Therefore, the air resistance flowing toward the air outlet 6 becomes large, resulting in a decrease in air volume and wind speed, and a decrease in heating and cooling capacity. That is, suction chamber 1
0 in the center and the distance from the blowing chamber 9, air resistance inevitably occurs. Therefore,
The wind speed distribution in the room also deteriorates, and the heating and cooling effect deteriorates. In particular, during heating, if the wind speed decreases, only the ceiling surface becomes warmer, which has the disadvantage that the heating effect becomes extremely poor.

OBJECT OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and aims to make the air resistance of a plurality of outlets the same to obtain uniform wind loss from each day and to improve the cooling and heating effect. .

Structure of the Invention The present invention comprises a main body of an air conditioner which is divided by providing a partition plate and has a blower running heat exchanger in each of the parallel flow paths which are clearly in the flow direction; A grill having an inlet and an outlet communicating with the flow path, an outlet communicating with the other flow path and having an outlet 1 parallel to the suction, and an inlet parallel to the outlet. The air conditioner is equipped with a two-way blowout type air conditioner that reduces air resistance in both flow paths.

DESCRIPTION OF EMBODIMENTS 1pJ An embodiment of the present invention will be described based on FIGS. 2 to 6. 16 is a main body of the air conditioner provided on the back side of the ceiling surface 16, 17 is a grill provided opposite to the main body 16 and facing downward from the ceiling surface 16, and has a suction port 18 on the side. , an air outlet 19 is provided. 20 is a blower provided on one side of the main body 15; 21 is a heat exchanger provided for the blower 20; and 22 is a drain pan provided below the heat exchanger 21. Then, the air flowing in from the suction port 18 is sent to the air tank 20. Heat exchanger 21° outlet 1
A lateral flow path A (not shown by arrow A) communicating with 9 is formed.

23 is a blower provided on the other side of the main body 15, and the blower IJ 19 serves as the blower port 19a on the other side.
C is connected. 21a is the suction (il) of this blower 23.
a heat exchanger installed in the side heat exchanger 2;
1, is long in the longitudinal direction, and is provided at an angle so that the suction port 18 communicates as a Suita port 18a. 22 a t, j: A drain pan provided below this heat exchanger 21, and integrated with the drain pan 22 provided on the side. Then, the air υ1 flowing in from the suction port 19a, the heat exchanger 21a, the blower 23. A flow path B indicated by an arrow B is formed which communicates with the air outlet 18a. A partition plate 24 is provided in the center of the main body 1 and partitions the flow paths A and B.

In the manual configuration, when the fan coil unit is operated, air also flows into one side of the main body 15 (in the case of Lull, the suction port 18), passes through the heat exchanger 21 via the blower 20, becomes cold air or warm air, and exits the air outlet. 19 blows into the room.

On the other hand, in the other space in the main body 16, the suction port 18 and the blowout port 19 are opposite to each other, and the portion that becomes the heat exchanger 21a is the suction port 1 of the blower 23! II place I
It is configured in β. That is, the air flowing in from the suction port 19a passes through the heat exchanger 21a by the blower 23, becomes cold air or warm air, and is blown into the room from the air outlet 18a. In this case, a blower and a heat exchanger are arranged so that the inlet and outlet on one side are the opposite, making it a two-way blowout type. In this embodiment, a plurality of blowers are used, but it is also possible to use a configuration in which the blowers are provided at -i11+- and 1-. Historically, air conditioners (fan coil unit and outlet (21) are placed at the same port, and the flow paths of cold or hot air are staggered, resulting in a two-way blowout type with less air resistance. Of course, it is possible.

Effects of the Invention As described above, the present invention provides a main body of an air conditioner having a blower and a heat exchanger in each flow path, and a flow path in which the flow paths are separated by partition plates and are arranged in parallel with different force directions. A suction port and an outlet [1, which are connected to one flow path, and f) an air outlet that communicates with the other flow path and are adjacent to the suction port 1, and a suction port that is adjacent to the air outlet. Since it is equipped with a grill, it can be a two-way blowout type with low air resistance. That is, since the distance from the intake port to the air outlet of the grill is short and there is little air resistance, the speed of air blowing from the grill becomes faster, the wind speed distribution within the campus is also improved, and a comfortable heating and cooling effect can be obtained. In addition, the blower on one side is pushed in (lIll) against the heat exchanger,
Air blower i7J on the other side: is installed on the suction side with respect to the heat exchanger. That is, by changing the blowing direction of the blower on the other side, it is possible to achieve practical effects such as eliminating the imbalance in the wind speeds blown in two directions as in the conventional case.
