DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air-conditioning control device for dividing an indoor space into a plurality of different temperature spaces by a jet stream, and is useful when applied to the formation of a different temperature space by an air curtain applied to a leisure facility or the like. Things.

2. Description of the Related Art FIG. 3 schematically shows a conventional air-conditioning control device in which a room is partitioned by an air curtain.

In a conventional air-conditioning control apparatus, as shown in FIG. 3, an indoor space 1 is divided into a high-temperature chamber RH and a low-temperature chamber RL by an air curtain formed by a jet 2 jetted by an jet nozzle 3 provided on the floor. It is divided into two different temperature spaces. The high temperature room RH is maintained at room temperature by heating or the like, and the low temperature room RL is maintained at room temperature by cooling or the like.

In this case, for example, in a high temperature chamber RH,
Jet (air curtain) 2 jetted from the jet nozzle 3
Forms a circulating flow 4 near the ejection port of the ejection nozzle 3. Further, when heat input from the surroundings, particularly heat from the floor surface, is large, an air current is generated by natural convection 5 so as to face the circulating flow 4. Such an airflow due to the natural convection 5 causes a decrease in separation performance for the air car curtain formed by the jet 2 to partition both spaces.

[0005]

As described above, in the conventional air-conditioning control device, the airflow generated by the natural convection 5 acts in the direction opposite to the jet 2 ejected from the injection nozzle 3. . For this reason, the natural convection 5 disturbs the air curtain formed by the jet 2, deteriorating the separation performance of the two spaces by the air curtain, and there is a problem that the indoor space 1 cannot be properly partitioned.

The present invention has been made to solve such a problem. By making the flow direction of a jet flow ejected from an injection nozzle coincide with the flow direction of a large air flow in a space, the two flows can be separated by the jet flow. It is an object of the present invention to provide an air conditioning control device which is appropriately partitioned to improve the separation performance.

According to a first aspect of the present invention, there is provided an air conditioning control apparatus for dividing an indoor space into at least two different temperature spaces by a jet from an injection nozzle. An air flow control nozzle for injecting gas into the space in a direction substantially the same as the flow direction of the circulating flow in order to promote a circulating flow generated in the vicinity of the ejection port of the injection nozzle by the jet flowing from the injection nozzle; Is provided.

[0008] The air-conditioning control device according to the second aspect of the present invention,
A low-temperature side space among the at least two different temperature spaces, a slope having a predetermined thickness of artificial snow sprayed on a slope inclined upward from the lower surface of the temperature space dividing portion is formed, and the low-temperature side space and the high-temperature side space are formed. A step portion is provided on the lower surface of the temperature space dividing portion, and the jet nozzle is provided at a high position of the step portion.
