  2. Description of the Related Art Conventionally, in air conditioner installation facilities including a large number of indoor units such as hospitals and department stores, the use of building multi-type air conditioners is increasing from the viewpoint of price and maintenance.

  As a measure for preventing nosocomial infections with this building multi-type air conditioner, for example, replacement of a filter about once a year (or sterilization cleaning) in a ceiling-mounted indoor unit constituting the air conditioner is generally used. However, such nosocomial infection prevention measures may leave harmful fungi in the indoor unit itself.

  For this reason, there is a strong demand from users of air conditioners in hospitals, department stores, etc. to remove the indoor unit itself and to sterilize and clean the indoor unit itself. The air conditioner manufacturer and the contractor are not responding to the request of the user side.

Conventionally, assuming the time of removal and relocation, it is possible to detach the refrigerant pipe by installing a valve in the field construction on the indoor unit (for example, floor-standing type), and the refrigerant contained in the indoor unit at that time using the refrigerant recovery device An air conditioner system configured to collect has been implemented.
However, using the refrigerant recovery device to recover the refrigerant causes an increase in work processes and an increase in work costs.

Further, an inspection port 124 with an openable / closable lid 123 is provided in a part of the ceiling plate 103.

  However, in the case of this conventional example, the indoor unit 100 itself does not have a structure that can be easily attached and detached. When the indoor unit 100 is once installed in the ceiling, the lifetime of the indoor unit 100 is exhausted or a part thereof is broken. The situation is that removal is not performed until the replacement time, as in the case of, for example.

  In Patent Document 1, a washing machine is attached to the blower motor of a ceiling-embedded indoor unit from below the ceiling, and the washing machine is operated to perform washing by spraying a cleaning liquid on the heat exchanger of the indoor unit. A cleaning device for a ceiling-embedded air conditioner configured as described above has been proposed.

  However, even in the case of Patent Document 1, cleaning is not performed by removing the ceiling-embedded indoor unit itself, and is not necessarily sufficient in terms of measures for preventing hospital infection, and harmful fungi remain in the indoor unit itself. There is a risk of doing.

  Patent Document 2 proposes a ceiling-embedded air conditioner having a configuration in which a plurality of indoor units installed on a ceiling and one indoor unit are sequentially connected by a pipe connection part and piping.

However, even in the case of Patent Document 2, the convenience of attaching and detaching each of the plurality of indoor units including each piping system and electrical system is not considered.

However, there is no need for refrigerant recovery around each individual indoor unit 1. From the point of view, the cost can be reduced.

  Furthermore, if a heat insulation kit (not shown) that can be easily applied to the pre-refrigerant piping system 10 is employed, the heat insulation work of the refrigerant piping system 10 can be facilitated.

  In the case of a multi-air conditioner system (a system in which a single outdoor unit controls a plurality of indoor units 1) as in this embodiment, a disconnection error occurs when the control board of one indoor unit 1 is removed. However, it is normal to cause an abnormal stop of the entire system including the other indoor units 1, but by adopting a detachable control board that does not cause an abnormal stop of the other indoor units 1. Thus, a detachable air conditioner system that can perform attachment / detachment of the individual indoor units 1 to / from the ceiling 50 without affecting the operation of other indoor units 1 can be provided.

  In the removable air conditioner system of the present embodiment described above, the configuration in which three indoor units 1 are connected to one outdoor unit 14 is described. However, the number of connected indoor units 1 is not limited to this. Of course, it can be implemented as an arbitrary number such as 10 units, 20 units.

  The present invention can be widely applied not only to the above-described ceiling-embedded indoor unit, but also to, for example, a wall-embedded indoor unit or an indoor unit having a structure that is attached in a state of being exposed from the ceiling.
