Overview of chapter one
1.1, Product summary
The ducted type unit means that the outdoor unit and the indoor unit are connected by a copper pipe and the
air-supply pipe leads to each room from the indoor. That is why it is called the ducted pipe unit. The detailed
working method is that: the indoor heat exchangers gather in an indoor unit, the cool air produced by the indoor
unit is sent to each room from the system air duct, then is sent back to the indoor unit via the air duct, after it is
cooled and mixed with some fresh air, it is sent out again. This is a central air conditioner with the complete air
system.
Gree’s A series of air conditioner unit with the air supplied by the small air duct combines the advantages of the
central air conditioner which are being comfortable and top-grade and the advantages of the small type of
separated home air conditioner which are being convenient and flexible in installation, etc. It is highly efficient,
energy-saving with a long air supply distance and good indoor air quality. It is reliable in operation and convenient
in usage and is widely applied to various small supermarkets, chain stores, families with multiple living rooms,
hotels, restaurants, offices, meeting rooms and villa families.
The existing models of the A series of small ducted type units are shown in Table 1.1-1.
