Description

Ball diffuser blower

The present invention relates to a device in which a blower and a ball diffuser have an integral structure.

In general, a bus air conditioner is installed to cool the inside of the bus, and most air conditioners installed in the bus are of a roof-top type and are installed on the roof of the bus.

As is well known, an air conditioner device includes a compressor, a condenser connected to the compressor through a pipe, an expansion valve, and an evaporator. The low-temperature/low-pressure refrigerant (gas state) supplied to the compressor passes through the compressor into a high-temperature/high-pressure gaseous state, and then is supplied to the condenser. It is converted into a high-temperature/high-pressure liquid state by exchanging heat with external air. Refrigerant that has become liquid through the condenser is temporarily stored in a reservoir tank, and after moisture is removed through a dryer, it is converted to a low-temperature/low-pressure liquid state by an expansion valve. The converted low-temperature/low-pressure liquid refrigerant is supplied to the evaporator, heat exchanges with the indoor air of the bus through the blower of the evaporator, and the low-temperature indoor air with heat exchange is supplied to the interior of the bus through a duct. The interior is cooled.

At this time, at the end of the duct used in a normal bus, a spherical ball diffuser is used to control the air volume by rotating it to supply low-temperature heat-exchanged air into the room. and ducts are each configured individually, and they have a structure that connects them with a duct and uses them.

Accordingly, since such a structure can be improved to have a more compact structure, there is a need for development of a device capable of being used for multiple purposes without limitation in the place of use.
