The air outlet for task air conditioning is opened and closed according to the individual's preference for the thermal environment, and conditioned air is blown into the room as necessary. It is necessary to ensure the required air volume including humidity adjustment and ventilation (introduction of fresh air) to remove substances such as VOC and CO _{2. In} conventional air conditioning systems, a separate air volume adjustment mechanism (VAV) is required for this purpose. ), Ducts and diffusive outlets were required for the ambient air conditioning system.

  On the other hand, in the situation where the airflow of conditioned air corresponding to each individual increases, it should be possible to reduce the amount of ambient airflow, but complicated control is required, and the small airflow can be reduced due to the characteristics of the airflow adjustment mechanism. As a whole, there was a situation where an excessive air volume was supplied.

  In addition, in a system that performs task air conditioning and ambient air conditioning with the same air outlet system, when many air outlets for task air conditioning are used, the air volume per unit decreases and the air volume necessary to obtain comfort cannot be obtained. There was a situation in which the entire air volume balance was lost and sufficient air volume did not reach the required location.

  The present invention aims to solve the above-described problems.

  In order to solve the above-described problems, in the present invention, an air outlet for performing task air conditioning corresponding to each individual is installed on the ceiling, and each of the air outlet is a directional outlet, a diffusive outlet, and a closed outlet. A personal air-conditioning system that can be operated as an element of ambient air-conditioning is proposed.

  The present invention also proposes a personal air conditioning system having the above-described configuration, in which the air outlet is automatically opened by a presence determination sensor and can be closed when the user is absent and closed when the user is absent.

  Further, the present invention proposes a personal air conditioning system in which the air outlet is operable in an intermediate state between the operations in the above configuration.

  In the present invention, in the above configuration, the air outlet includes a directional outlet section and a diffusive outlet section in the box body, and a directional outlet section on one side of the box body corresponding to each section. Switching provided with a diffusive blowout part and an opening corresponding to each section on the other side of the box at every 120 ° in the circumferential direction, and an opening in the range of 120 ° on the circumference We propose a personal air-conditioning system with a rotatable plate.

  Further, the present invention proposes a personal air conditioning system having a radiation panel for performing ambient air conditioning on the ceiling in the above configuration.

  The present invention also proposes a personal air conditioning system having a constant air volume (CAV) mechanism in the conditioned air path to the air outlet in the above configuration.

  Furthermore, in the present invention, a directional blowing section and a diffusive blowing section are provided in the box, and a directional blowing section and a diffusing blowing section are provided on one side of the box corresponding to each section. On the other side, an opening corresponding to each section is arranged every 120 ° in the circumferential direction, and a switching plate body having an opening in the range of 120 ° on the circumference is provided for rotation. An air outlet device is proposed.

In the air conditioning system of the present invention, indoor dust, CO ₂ , moisture, and the like are often generated by occupants, so supplying the necessary amount of conditioned air to the seated portion is a comfortable environment with a minimum airflow. Can be realized.

  Further, according to the present invention, task air conditioning can be performed according to personal preference by adjusting the blowing of conditioned air from the air outlet provided on the ceiling corresponding to each individual for each individual. In other words, air-conditioned air from the air outlet can be switched between directional blowing and diffusive blowing by any individual operation, and directional blowing and diffusive blowing can be used together. The proportion of conditioned air can be adjusted.

  Therefore, if the ambient air conditioning system involves air blowing, the amount of air blowing can be reduced, and by applying the ambient air conditioning system without air blowing, a separate air volume adjustment mechanism (VAV) , Ducts and diffusive outlets are not required.

  In other words, in the present invention, by using the radiant panel for ambient heat generation with respect to the heat generated from the base, the shared OA equipment, and the heat generated around the outer wall, it is possible to reduce the processing heat ratio of air conditioning by air. In addition, air-conditioning using a radiant panel can use cold water at a higher temperature, so it has the advantage of high-efficiency use of energy, such as higher heat source performance efficiency and the ability to use secondary cold water. There is an advantage in the thermal environment that a feeling of airflow can be reduced.

Thus, in the present invention, when combining the air outlet of the task air conditioning configured to be able to switch each operation of directional blowing, diffusive blowing and closing, and radiation air conditioning, dust removal and humidity adjustment, A separate air volume adjustment mechanism (VAV), duct, and diffusive air outlet for ensuring the required air volume including ventilation (introduction of fresh air) for removing substances such as VOC and CO ₂ are not required.

  It is always necessary if a constant air volume mechanism is provided in the air-conditioning air path to the air outlet so that the amount of air-conditioned air blown from the air outlet is constant regardless of the operation of the diffusive blow and the directional blow. With the minimum amount of air, appropriate air conditioning can be performed, and it is possible to maintain a comfortable indoor environment while greatly reducing the energy required for air conveyance.

  In the air blowing device for air conditioning described above, each operation of directivity blowing, diffusive blowing, and closing can be switched by the rotation angle of the switching plate body, and can be operated in an intermediate state between each operation by the rotation angle. can do.
