Abstract

PURPOSE:To improve the comfortability of a thermal environment by forming a ventilating duct communicating with a conditioned air supply and having a highly heat conductive upper portion, forming a plurality of blowout openings for letting a duct space and a room communicate with each other in the upper portion of the ventilating duct and providing the rear of the lower portion of the back of a chair with an opening. CONSTITUTION:When a plurality of heating blowout openings 10, an opening 11 and a ventilating duct 9 are opened and a cooling blowout opening 6 is closed in heating, the conditioned air from a wind path 2 is blown out from a plurality of the heating blowout openings 10 and the opening 11 via the ventilating duct 9 without blowing in a ventilating path 3. At this time, a foot heating is conducted by a warm and ultra-soft wind. Further, heating the highly heat conductive upper portion 12 of the ventilating duct 9, a radiant heat from the upper portion 12 of the duct 9 acts as a floor heater to perform a foot heating in a working area. Thus, a comfortable heating condition is formed without the fact that a warm wind blows against the face of an office worker as conventional, enabling the comfortability of a thermal environment to be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a personal air conditioner that air-conditions a space near an office worker, such as an office work area.

2. Description of the Related Art Conventionally, this type of air conditioner has been of the female type, as shown in FIG. That is, the vertical wall 6 integrally forms with the desk 4 a ventilation passage 3 that communicates with the air passage 2 through which conditioned air supplied from a conditioned air supply source (not shown) provided at the bottom of the floor 1 passes.
A cooling air outlet e and a heating air outlet lower are provided above and below the standing wall 6, and the conditioned air is blown out toward the office worker or upwardly in front of the office through these air outlets. Ta. Number 8 is a chair.

Problems to be Solved by the Invention However, in such conventional air conditioning systems, during heating, warm air is blown from the heating blow-off lower toward the legs of the occupant, but the warm air Y rises due to buoyancy. This creates a problem in that residents feel uncomfortable because their faces are warmed without warming their feet.

The present invention is intended to solve the above-mentioned conventional problems, and aims to improve the comfort of the thermal environment for the office worker in the office area.

Means for Solving the Problems The present invention forms a ventilation duct in the lower floor of the desk that communicates with a conditioned air supply source and whose upper part has high thermal conductivity, and connects the duct space and the room in the upper part of the duct. A plurality of air outlets are provided in communication with each other, and an opening is provided at the lower rear of the back of the chair.

Effects The present invention has the above-described configuration, and at the same time prevents hot air from rising to the face of an office worker in the office area during heating, and at the same time, allows the first opening at the top of the ventilation duct to blow warm air from the M breeze. Furthermore, radiation from the upper part of the duct heats the feet, improving the comfort of the thermal environment.

Example An embodiment of the present invention will be described below with reference to FIG.

Incidentally, the same parts as in the conventional example are given the same reference numerals, and the description thereof will be omitted.

In the figure, 9 is a heating ventilation duct communicating with the vertical wall, and 1o is a plurality of heating air outlets bored in the upper part of the heating ventilation duct 9. Reference numeral 11 denotes an opening provided at the rear of the lower part of the back of the chair. The cooling outlet 6 and the multiple heating outlet 10° opening 11 can be opened and closed as desired by opening/closing means (not shown).

Next, we will discuss the operation.

During heating, there are multiple heating outlets 10. The opening 11 and the ventilation duct 9 are opened, and the cooling outlet 6 is closed.

When set in this way, the conditioned air from the air duct 2 does not go to the ventilation duct 3, but instead passes through the ventilation duct 9 to the multiple heating air outlets 10. It is blown out from the opening 11. At that time, the warm air blown out from multiple openings is used to heat the feet.

Furthermore, the duct upper part 12 with high thermal conductivity forming the ventilation duct 9 is heated, and the radiant heat from the duct upper part is used to
It acts as a floor heater and heats the feet in the office area.

Therefore, unlike in the past, warm air does not hit the face of the office worker, resulting in a comfortable heating condition.

In this embodiment, the ventilation duct is provided on the upper surface of the floor, but it may also be provided under the floor or integrally with the floor.
It is located at the bottom of the desk, and the upper part of the duct has good thermal conductivity, and multiple air outlets are drilled in the upper part of the duct to blow out ultra-fine warm air, and the remaining warm air is sent to the rear opening at the bottom of the back of the chair. The same effect can be obtained by blowing out more air.

Effects of the Invention As is clear from the above description, the present invention forms a ventilation duct on the floor surface under the desk, the upper part of which communicates with the conditioned air supply source has high thermal conductivity, and the upper part of the duct has a duct space and a room. In addition to having multiple air outlets that communicate with each other, we also installed an opening at the rear of the lower back of the chair, which eliminates the discomfort of hot air hitting the worker's face during heating, and also allows ultra-light air to flow through the multiple air outlets. The warm air blown out from the duct heats the feet, and the radiation from the top of the duct heats the floor, making it possible to significantly improve the comfort of the thermal environment for workers in the work area.
