Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioning system for a living space.

Conventional air conditioning systems have the following inconveniences and drawbacks because the ducts are installed in the ceiling or under the floor.

Space is required to install the ducts, and the floor height increases accordingly, making the construction cost itself relatively high.

As the duct shrinks, expands, and bends, the conditioned air flowing through the duct encounters resistance, which increases the power to convey the conditioned air, resulting in energy loss.

Suspension of ducts and insulation work are required, which not only increases construction costs but also lengthens the overall construction period.

Due to changes in the layout of the building, the ducts must also be renovated.

Air conditioning cannot be controlled uniformly throughout the entire living space, resulting in localized overheating or overcooling, which results in wasted energy consumption.

In order to eliminate the inconveniences of such duct type air conditioning systems, a so-called ductless air conditioning system, which is a conditioned air distribution control device (see Japanese Patent Publication No. 53-24726), has been developed that uses airflow inside the ceiling. However,
Even with this air conditioning system, there was a lot of wasted energy consumption, and it was difficult to provide comfortable and satisfying air conditioning for individual residents. In other words, assuming a living space where multiple people are working at a desk,
Trying to air-condition the entire living space is a waste of energy, so we install conditioned air outlets on the ceiling directly above or near each resident to air-condition the area surrounding each resident. I try to figure it out.
Even so, it is very difficult to constantly fill the area from the ceiling to the floor where each resident is occupied with comfortable conditioned air, and even if it were possible, the conditioned air that is above each resident's head would be extremely difficult to fill. This results in wasted energy consumption that is completely unnecessary for residents. Not only that, but each time you change the layout of your living space, you have to change the installation of conditioned air outlets.
In extreme cases, it may be necessary to replace the entire ceiling panel.

In view of the inconveniences and shortcomings of the conventional systems, the present invention makes the space under the floor constituting the living space a conditioned air chamber, and creates a conditioned air outlet at a desired location on the floor so that the conditioned air in the conditioned air chamber can be distributed individually. By extracting air from the air into the air, we can reduce wasted energy (conditioned air) consumption and easily fill each resident's area from their feet to their heads with comfortable conditioned air, and we have created an air conditioning system that is easy to install and inexpensive. This is what we intend to provide.

An example of implementing the present invention will be described below based on the drawings. In the drawings, A represents a floor B, a wall C, and a ceiling (not shown).
It is one living space composed of.

The floor B constituting the living space A may be a floor with a conventionally constructed structure, but in consideration of changes in the layout within the living space A, a floor with a raised floor structure as in the illustrated embodiment is preferable. That is, this free access floor is constructed by regularly setting up support legs E on a concrete base surface D, and placing and laying floor panels F over each of the support legs E in the form of a bridge.

Therefore, the space under the floor B that constitutes the living space A, that is, between the floor B and the concrete base surface D, is designated as a conditioned air room G, and the outlet of a large air conditioner is faced into this conditioned air room G. Alternatively, an appropriate number of small air conditioners H may be installed as in the illustrated embodiment.

By installing an appropriate number of small air conditioners H in the conditioned air room G as in this embodiment, only the air conditioner H that is supplying conditioned air to the resident will be stopped when the resident goes out and is absent. This makes it possible to reduce wasteful energy consumption. The conditioned air in the conditioned air room G is taken out to the living space A through conditioned air outlets I opened at desired locations on the floor B, specifically near the feet of each occupant.

The conditioned air intake port I opens at a desired location on floor B, more specifically near the feet of each resident.If floor B has a structure that is conventionally constructed, the conditioned air outlet I is opened at a desired location on floor B, and if floor B has a structure that is conventionally constructed, it must be opened at a desired location on floor B. However, if the floor B is constructed of a free access floor as in the illustrated embodiment, the opening can be formed simply by removing the floor panel F at the desired location. Specifically, a floor panel with a conditioned air outlet I formed in advance (see Figure 2)
Alternatively, a single floor panel can be divided into strips (see Figure 3), and these floor panels F are installed near the feet of each resident. .

Furthermore, a fan 1 is attached to the conditioned air outlet I to forcibly take out the conditioned air A in the conditioned air room G into the living space A, and at the same time, an appropriate conditioned air zone is formed for each resident. Air circulation device J
It is desirable to provide

The air circulation device J has an air intake port 2 at the bottom and a conditioned air outlet 3 at the top, and is fixed to the desk K of each resident, for example, to form a conditioned air zone around the resident. It is something that makes you

In addition, 4 in the figure is a lighting fixture.

In this way, the present invention makes the under-floor space of the floor constituting the living space a conditioned air chamber, and the conditioned air in the conditioned air chamber is individually taken out by opening the conditioned air outlet at a desired location on the floor. Therefore, it is possible to eliminate all the inconveniences and drawbacks of conventional duct-based air conditioning systems, as well as the inconveniences and drawbacks of ductless air conditioning systems that use airflow inside the ceiling as proposed in Japanese Patent Publication No. 53-24726, etc. It is possible.

In other words, it is possible to easily create a comfortable conditioned air zone for each resident from the feet to the head, and since the conditioned air does not reach spaces that are not necessary for the occupant from the head to the ceiling, the conditioned air can be used efficiently. It can be used effectively and the consumption of wasted energy (conditioned air) can be greatly reduced.

Moreover, when the resident goes out and is absent,
Since only the conditioned air zone of the resident can be easily eliminated, wasteful energy (conditioned air) consumption can be further suppressed.

In addition, by configuring the floor that makes up the living space with a raised floor, even if the layout within the living space is changed, the floor panel for the conditioned air outlet can be simply replaced without damaging the floor. This makes it possible to easily create conditioned air zones corresponding to each resident.

Furthermore, since the air conditioning system of the present invention utilizes the underfloor space as a conditioned air chamber, the entire system can be easily constructed and installed at low cost.

Therefore, the intended purpose can be achieved.
