The present invention relates to an air conditioning device, its component units, and a complex air conditioning system.

An air conditioning device that integrates a plurality of devices such as an air passageway, a refrigeration circuit, and a blower is known (for example, JP6140878B by the applicant). Such an air conditioner can, for example, be brought into the user-side installation space after the plurality of devices are integrated at the manufacturer's factory, thereby reducing the effort of assembly work performed in the user-side installation space.

In the above-mentioned air conditioner, when an increase in processing capacity such as air supply amount or cooling performance is required, the processing capacity may be improved by increasing the output of the compressor of the refrigeration circuit or increasing the output of the blower.

However, higher outputs of compressors and blowers result in larger air conditioners, and as a result, there are cases where transportation of the air conditioners is hindered. Specifically, even if it is impossible to load the air conditioner into a container, or even if the air conditioner can be transported to the user's side in a container, etc., excessive effort is required when transporting it from the container, etc. to the user's installation space. There are cases where it happens.

On the other hand, even when the air conditioner is enlarged, if the components of the air conditioner are transported separately, each component can be brought into the user's installation space without any trouble. However, since the load of the air conditioner assembly work performed in the user-side installation space increases, the merit of integration is lost.

The present invention has been made with an eye on the above-mentioned circumstances, and provides an air conditioner and its component units that can avoid problems in transportation and, for example, excessive effort in assembly work performed in the installation space on the user's side, and The purpose is to provide a complex air conditioning system.
