Rooftop Ac Unit Suitable For Textile factory Free Cooling Function
Optional
Rooftop systems offer a flexible way to provide treated air for one
to eight-story buildings. Many options and configurations are
available to satisfy a wide number of applications. Fresh outside
air is mixed with return air from the occupied space and then
filtered, conditioned, and supplied back into the building.
Conditioning involves cooling, dehumidifying, or heating the air
for optimal space comfort. Rooftop units can serve a single zone,
or an entire building filled with many zones. Some units can be
specifically designed for make-up air, where only outside air is
treated and sent to the space. Inverter compressors, belt-less EC
fans, and energy recovery solutions make rooftop systems an
easy-to-maintain, energy-efficient choice for conditioning any
space. Electric, hot water, steam, and heat pump heat provide
reliable heating for spaces with colder seasons and climates.
Main Features Of Rooftop Air Conditioner:
1. Various products and wide application
The series of Rooftop units include many different specifications
which can completely meet the demand of home and commercial places
and offer you a comfortable and pleasant environment.
2. Complete air system, simple and hygiene, less components, easy
maintenance. The flexible and concise design makes the maintenance
very simple. Disassembling several bolts from any side of the unit
can repair any part of the unit.
3. Microcomputer intelligent controller can reach four control
modes: cooling, dehumidifying, and ventilation. It also has the
functions of timing on-off and failure display.
Application:
Used in a large number of fresh air and exhaust air conditioning
system.
Such as laboratory, for security needs, must be a lot of wind,
which also need to add fresh air, if you can recover the energy of
exhaust, to preheat or pre cooling fresh air can be a lot of
energy.
Full heat recovery can recover latent heat, and partial heat
recovery can not be.
Where it can achieve the recovery of phase change heat of the
occasion, can use the full heat recovery technology.
