Abstract

PURPOSE:To keep an air chamber under a floor at a constant low pressure by a method wherein a fan is installed inside a partition and under-floor conditioned air is taken into the partition. CONSTITUTION:The conditioned air generated by an air-conditioner 13 is delivered from a conditioned-air outlet 14 to an air chamber 16 so as to keep it at a specified pressure. Then, when a fan 3 is operated, the conditioned air is led from an outlet 8 to an air compartment along a duct 9 and discharged into an ambient space from an air outlet 12 through an air chamber 11 by the fan 3. The return air is led from conditioned an air suction port 18 to a suction port 20 of the air-conditioner 13 along a suction duct 9. The pressure losses generated in the duct 9 and the air chamber 11 are compensated by the fan 3. Therefore, when the number of the partitions is increased, the air chamber 16 can be kept at a constant pressure by increasing the delivery capacity of the air-conditioner 13 by an air flow rate corresponding to the additional partitions.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a partition compatible with underfloor air conditioning, which has a blower built into its main body and has a function of blowing out underfloor conditioned air from the partition to an ambient space.

Conventional technology Generally, when a partition is used to divide a room, the inside of the partition is divided into areas such as windows and air conditioners.

The temperature in the room and inside the partition were uneven because the airflow from ventilation fans and other equipment was blocked. As a countermeasure against this, conventionally, as shown in FIG. 3, a raised floor 102 is provided above a floor 101 to create an air chamber part 103, and an air outlet 105 of an air conditioner 104 is installed in the air chamber part 103. The raised floor 102 has an air outlet 10
A duct 110 connects the partition 107 to a suction hole 109 provided at the lower part of the air chamber part 108 of the partition 107, and an air conditioning outlet 111 is provided at the upper part of the air chamber part 108 of the partition 107. It was getting worse. Furthermore, the ceiling surface 112 has an air conditioning inlet 1.
13 is provided, and the air conditioner 10 is connected to the air conditioner 10 through a suction duct 114.
It was connected to the suction port 115 of No. 4.

When the air conditioner 104 is operated with this configuration, conditioned air passes through the air chamber part 103 from the outlet 105, passes through the duct 110 from the outlet 106, and passes through the partition 107.
The return air passes through the air chamber part 108 of the air conditioner 10 and is discharged from the air conditioning outlet 111 to the ambient space, and the return air is conveyed from the air conditioning suction inlet 113 to the suction duct 114 and the air conditioner 10
It was back to 115 in the suction position of 4.

Problems to be Solved by the Invention However, in the above conventional technology, there is a pressure loss in the air chamber inside the partition and a pressure loss in the duct connecting the floor and the partition, so the pressure in the air chamber under the floor must be set on the positive side. As the number of partitions increases, the blowing capacity of the air conditioner must be increased to increase the pressure, and the problem is that air leaks more easily from the floor.

The present invention solves the above problems by incorporating a blower inside the partition, connecting it to the floor through a duct, taking in underfloor conditioned air into the partition, and blowing it out into the ambient space, thereby creating an underfloor air chamber. It is an object of the present invention to provide a partition compatible with underfloor air conditioning, in which the pressure in a portion can be kept constant regardless of the number of partitions, and the blowing capacity of an air conditioner does not need to be so large.

Means for Solving the Problem In order to solve this problem, the present invention provides a blower disposed inside the partition main body, an air outlet formed in the front surface of the partition main body, and an air chamber provided in front of the blower, The air chamber and the raised floor are connected by a duct.

Effect: With this configuration, the pressure loss that occurs in a portion of the air chamber inside the partition and the duct can be compensated for by the blower built into the partition, and the pressure inside the air chamber under the floor can be kept low and constant regardless of the number of partitions. As a result, conditioned air will be blown out into the ambient space.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, a blower 3 having an impeller 1 and an electric motor 2 is built into a partition main body 4. Air blower Ia
An air chamber 6 having a suction port 5 is provided in front of the air chamber 3, and a duct 9 connects the raised floor 7 to a closed air outlet 8. The upper part of the partition main body 4 is an air chamber 1 for the air blown from the air outlet 10 of the blower 3.
1, and an air outlet 12 is provided at the front. An air conditioning outlet 14 of the air conditioner 13 is provided in a part 16 of the air chamber between the raised floor 7 and the bottom floor 15, and an air conditioning inlet 18 is provided in the ceiling surface 17, and a suction duct 19 is provided.
It is connected to the suction port 20 of the air conditioner 13 via.

In the above configuration, when the air conditioner 13 is operated, the air conditioner 41
The conditioned air generated by the air conditioner 113 is discharged from the air conditioning outlet 14 into the air chamber portion 16, and reaches a certain pressure. When the blower 3 is operated here, the conditioned air is guided from the blower 3 to the air chamber through the duct 9, passes through the air chamber 11 from the blower 3, and is discharged from the blower outlet 12 into the ambient space. The return air is guided to the air conditioning inlet 2o of the air conditioner 13 through the air conditioning inlet 18 and the suction duct 19.

With this configuration, the pressure loss that occurs in the duct 9 and the air chamber 11 is offset by the blower 3, so even if the number of partitions increases, the blowing capacity of the air conditioner 13 only needs to be secured for the amount of air, and the air chamber The pressure in part 16 can also be constant. Furthermore, since the pressure in the air chamber portion 16 can be kept low, air leakage from the raised floor 7 can also be reduced.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, by providing a blower in the partition and taking the underfloor conditioned air into the partition, the pressure in a part of the underfloor air chamber can be reduced ( Since it can be kept constant, the blowing capacity of the air conditioner can be reduced, and air leakage from the floor can be reduced.
