Abstract

PURPOSE:To improve the confortableness of thermal atmospherein an office area by a method wherein air inlets and outlets are connected to two ducts with built-in fans that are installed inside a wall, and the locational relation of the air inlets and outlets on the two ducts are reversed each other. CONSTITUTION:A first air duct 7 and a second air duct 8 are vertically installed inside a partition wall 2, and a first fan 11 and a second fan 12 are installed inside the first and second air ducts 7 and 8 respectively. A first air outlet 13 located below a desk 5 on the surface of the partition wall 2 facing the desk 5, and a first inlet 14 located on the upper portion of the partition wall 2 are connected to the first air duct 7. A second air inlet 15 located below the desk 5, and a second air outlet 16 located above the desk 5 are connected to the second air duct 8. As a result, in heating operation, warm air is sent toward the feet of a resident, and in cooling operation, cool air is sent toward the head of the resident, so that a comfortable atmosphere can be accomplished in the office area of the resident, keeping the head cool and the feet warm.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an air conditioning system for a personal office area divided by partitions or the like.

2. Description of the Related Art Conventionally, in the case of heating and cooling air conditioning in offices, etc., the air conditioning was generally applied to the entire room, and the entire room was kept at an even temperature.

Problems to be Solved by the Invention However, although these conventional air conditioning systems are designed to maintain a uniform temperature throughout the room, in reality, during both cooling and heating, the room temperature is higher than the upper part due to the difference in air density. shows a tendency to be high and low at the bottom. Follow.

Therefore, the thermal environment of the indoor occupant becomes uncomfortable, with a hot head and cold feet, which is completely opposite to the cold head and cold feet that is said to be ideal for the occupant.

In addition, if there is nothing in the room, the flow of conditioned air will be relatively smooth, but in reality, if a desk is placed and the office area is divided by partitions, the airflow distribution of conditioned air will be poor, and Temperatures were uneven, with some being too hot and some being too cold, making the environment even more uncomfortable for residents.

The present invention solves the above-mentioned conventional problems, and aims to improve the comfort of the thermal environment for residents in an office area divided by partitions.

Means for Solving the Problems The present invention provides two ventilation passages with built-in blowers inside a partition, communicates an inlet and an outlet with each ventilation passage, and provides a The positional relationship of the inlet and outlet are respectively reversed.

Effects The present invention, with the above-described configuration, creates a comfortable thermal environment for the occupants by making the thermal environment of the occupants in the office area divided by the partitions more likely to have cold heads and warm feet.

EXAMPLE An example of the present invention is shown in FIGS. 1, 2, 3, and 4.
This will be explained with a diagram.

In the figure, 1 is the front partition 2. This is an office area divided by side partitions 3 and 4, and a desk 6 and a chair 6 are arranged within this space.

Inside the front partition 2, a first ventilation passage 7 and a second ventilation passage 8 are provided in the vertical direction without directly communicating with each other.
A first blower 11 and a second blower 12 having air volume control means 9.10 (not shown) that can vary the air volume are arranged at the upper part of the first ventilation passage 7 and the lower part of the second ventilation passage 8, respectively. .

One end of the first ventilation passage 7 opens below the desk 6 to form a first air outlet 13, and the other end opens to the upper part of the front partition 2 to form a first suction port 14, and the first air blower 11
The air in the upper part of the room is sucked in and blown out below the desk 6.

Further, one end of the second ventilation passage 8 is opened downward from the desk 6 and the second ventilation passage 8 is opened downward from the desk 6.
A suction port 16 is formed, and the other end is opened above the desk 6 to form a second
An air outlet 16 is formed, and the air below the desk 6 is sucked in by the second blower 12 and blown out to the vicinity of the occupant above the desk 6.

In addition, the first air outlet 13. First suction port 14. 2nd suction port 1
6. The opening and closing of the second air outlet 16 can be arbitrarily controlled by a resident in the office area 1.

Next, we will discuss the operation.

First, when the air conditioning of the entire room is in the heating state, the temperature distribution in the room is high at the top and low at the bottom, as described above.

At this time, the first blowout port 13 and the first suction port 14 are opened, and the second
The first blower 11 is operated with the suction port 16 and the second blowout port 16 closed. Then, the indoor air flows as shown by the arrows in Figure 3, and the high-temperature air in the upper part of the room is sucked in from the first suction port 14 and discharged from the first air outlet 13, so that the air flows near the occupant's feet. Warm air from the air conditioning system will come down, making your feet warm.

Next, when the air conditioning of the entire room is in the cooling state, the first air outlet 1
3 and the first suction port 14 are closed, the second suction port 16 and the second blowout port 16 are opened, and the second blower 12 is operated. Then, the indoor air flows as shown by the arrows in Fig. 4, and the low-temperature air in the lower part of the room is sucked in through the second suction port 15, and the cold air hits the occupant's head from the second air outlet 16. This results in a cooling sensation on the head.

Further, since the air volume of the first fan 11 and the second fan 12 can be varied by the air volume control means 9 and 10, it can be controlled in accordance with the optimal air conditioning conditions of the occupants in the office area 1.

Furthermore, whether the general air conditioning is for heating or cooling, the
．． The second air outlet 13.16 and the first air outlet 13.16. Second suction port 14.1
By opening 5 and operating the first and second blowers 11 and 12, it is possible to simultaneously supply low-temperature air to the head 9 and high-temperature air to the feet.

Therefore, the thermal environment of the occupants in the office area is such that their heads are cold and their feet are warm, making it possible to obtain a comfortable environment.

Effects of the Invention As is clear from the above description, the present invention provides a first ventilation passage and a second ventilation passage in the vertical direction inside the partition, and a first and second air blower in the first and second ventilation passages, respectively. The first air outlet provided below the desk on the surface of the partition facing the desk and the first suction port provided at the top of the partition are communicated with the first ventilation path, and the The second air inlet installed above the desk and the second air outlet installed above the desk are connected to the second ventilation duct, so warm air is directed to the feet of the occupants during heating and to the head of the occupant during cooling. By supplying cold air, the thermal environment of the occupants in the office area will be such that their heads and feet will be warm, making it possible to obtain a comfortable environment.
