  On the other hand, for example, research and development facilities are required to respond quickly to changes in the times, so changing the laboratory layout and indoor environment (ie, changing the existing air conditioning system) to meet diverse experimental needs It is necessary to respond flexibly.

  In research and development facilities (conventional air conditioning systems), the temperature and humidity of the processing air supplied from the air conditioner are adjusted by the fan coil unit installed on the ceiling surface, and supplied to each laboratory through this fan coil unit. ing. For this reason, when changing the air conditioning system, it was necessary to add a fan coil unit corresponding to the increase in air load, resulting in increased capital investment and interruption of research and development associated with the construction. . In addition, since the maximum supply amount of processing air is limited to the supply amount commensurate with the size of existing ducts (main ducts, etc.), it may not be possible to flexibly cope with the expansion of laboratories.

  In view of the above circumstances, the present invention provides an air conditioning system that can flexibly respond efficiently and economically even when a laboratory layout or indoor environment needs to be changed in a research and development facility, for example. With the goal.

  In order to achieve the above object, the present invention provides the following means.

  An air conditioning system according to the present invention includes a loop duct that is connected in a ring shape, a plurality of air conditioners that are connected to the loop duct, and supplies processing air to the loop duct, and one end and the other end that are connected to the loop duct. And an air volume duct for supplying the processing air with an air volume corresponding to the indoor load from the outlet.

  In the present invention, the processing air is supplied from a plurality of air conditioners to the loop duct and the air volume duct, and the processing air is supplied from the outlet of the air volume duct to the room and the like. Even if the outlet is provided, the pressure of the processing air flowing through the duct can be kept substantially constant. That is, since ventilation can be performed by compensating for excess and deficiency with a plurality of air conditioners, it is not necessary to limit the connection location of the air flow duct to the loop duct and the installation location of the air flow duct outlet.

  According to the air conditioning system of the present invention, ventilation can be performed by compensating for excess and deficiency with a plurality of air conditioners, so there is no need to restrict the connection location of the air flow duct to the loop duct and the installation location of the air flow duct outlet. . As a result, for example, when it is necessary to change the laboratory layout or the indoor environment at a research and development facility, the fan coil unit expansion work (renovation work: cold water piping work, power supply work, etc.) is no longer necessary. Therefore, it is possible to cope with only the construction of the air volume duct. Therefore, it is possible to efficiently and economically respond to the change of the air conditioning system without increasing the capital investment accompanying the addition of the fan coil unit or the like, or interrupting the research and development with the construction.

It is a figure showing an air-conditioning system concerning one embodiment of the present invention.

  Hereinafter, an air conditioning system according to an embodiment of the present invention will be described with reference to FIG. This embodiment relates to an air conditioning system provided in a research and development facility (building).

  As shown in FIG. 1, the air conditioning system A of the present embodiment is provided on each floor of the research and development facility T, and includes a loop duct 1, a plurality of air conditioners 2, and an air volume duct 3. The loop duct 1 is a main duct that is connected in an annular shape, and is formed in a rectangular shape along the outer periphery of the research and development facility T in this embodiment.

  The air conditioner 2 cleans the outside air taken in and adjusts the temperature and humidity for processing. In this embodiment, four air conditioners 2 are connected to the loop duct 1 so as to supply process air (fresh air + circulated air) to the four corners of the loop duct 1, respectively. Further, fresh air is mixed with circulating air and processed by the air conditioner 2, and a necessary amount is supplied to various places by the air conditioner 2 and the loop duct 1.

  The air volume duct 3 is a supply duct for supplying the processing air supplied and distributed from the air conditioner 2 to the loop duct 1 to the laboratory T1 of the research and development facility T, and one end and the other end are respectively connected to the loop duct 1. Connected and erected. Further, the air volume duct 3 is provided with an outlet at a predetermined position, and by providing a variable air volume device (VAV) at various places, a necessary amount according to the application can be supplied. It is comprised so that it can supply. In the present embodiment, a plurality of airflow ducts 3 are connected to the loop duct 1, and the airflow ducts 3 disposed in the experiment area (laboratory room T1) include three locations for each span of the experiment area T1. An outlet is provided. The treated air is mixed with fresh air and passes through a filter, so there is no problem in quality.

  In the air conditioning system A of the present embodiment configured as described above, outside air is taken in by each air conditioner 2, the taken outside air is cleaned, and the temperature and humidity are reduced by the fan coil unit built in each air conditioner 2. The treated air thus adjusted and treated in this way is supplied to the loop duct 1. Further, the processing air flows through the loop duct 1 and is supplied to the air volume duct 3, is taken out from the outlet of each air volume duct 3, and is supplied to the laboratory T <b> 1 and the like.

  At this time, in the air conditioning system A of the present embodiment, the processing air is supplied from the four air conditioners 2 via the annular loop duct 1 and the air volume duct 3 installed on the loop duct 1, so the ducts 1, 3 The pressure inside becomes almost constant. As a result, the processing air having a desired air volume can be supplied to the laboratory T1 and the like while compensating for excess and deficiency with the four air conditioners 2.

  When the laboratory layout or the room environment needs to be changed, the pressure of the processing air flowing through the ducts 1 and 3 is no matter where the airflow duct 3 is connected or where the outlet is provided. Because it is kept almost constant, the fan coil unit expansion work (refurbishment work: cold water piping work, power supply work, etc.) is no longer necessary, and it is only necessary to add, for example, an airflow duct 3, and a modified laboratory Air conditioning suitable for layout and indoor environment can be performed. That is, since all the ducts 1 and 3 are connected in a loop shape to cope with the peak load, individual changes such as the laboratory T1 can be handled in the entire building.

  Therefore, in the air conditioning system A of the present embodiment, the processing air is supplied from the plurality of air conditioners 2 to the loop duct 1 and the air volume duct 3, and the processing air is supplied from the outlet of the air volume duct 3 to the room. Regardless of where the airflow duct 3 is connected and where the outlet is provided, the pressure of the processing air flowing through the ducts 1 and 3 can be kept substantially constant. That is, since ventilation can be performed with a plurality of air conditioners 2 to compensate for excess and deficiency, there is no need to restrict the connection location of the air flow duct 3 to the loop duct 1 and the installation location of the outlet of the air flow duct 3.

  As a result, when the laboratory layout or room environment needs to be changed at the research and development facility T, the fan coil unit expansion work becomes unnecessary as in the conventional case, and only the air volume duct 3 expansion work can be handled. Is possible. Therefore, it is possible to efficiently and economically respond to the change of the air conditioning system A without increasing the capital investment accompanying the addition of the fan coil unit or the like, or interrupting the research and development with the construction.

  As mentioned above, although one Embodiment of the air conditioning system which concerns on this invention was described, this invention is not limited to said embodiment, It can change suitably in the range which does not deviate from the meaning. For example, the air (circulated air) supplied from the air volume duct 3 into the room or the like may be introduced into each air conditioner 2, and the processed air processed again by each air conditioner 2 may be supplied into the room or the like. In addition, it is possible to provide a hot air duct to prevent overcooling of a room that requires an air volume from the load. At that time, a mixed variable air volume device (VAV) that mixes the hot air and the cold air is provided at a necessary location.
