Energy Saving Commercial Electric Heating Rooftop Air Conditioner
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 big number of applications.
Fresh outside air 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 designed specifically for
make-up air, where only outside air is treated and sent to 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 space
with colder seasons and climates.

The unit has its cold and heat source and is air-cooled direct
evaporative air-conditioning equipment. The entire air-conditioning
system is only composed of an outdoor host and an indoor air duct.
No cooling water and chilled water systems are required. It is easy
to install and use, suitable for water-scarce areas.
The unit is designed for open-air installation on the roof or
outdoor open space. It has the performance of anti-sun exposure,
anti-corrosion, anti-torrential rain, etc., which can save the cost
of air conditioning machine room and civil engineering.
Both the evaporator and condenser adopt enhanced heat transfer
technology, which is highly efficient and energy-saving; the main
parts are all imported high-quality products with excellent
performance.
The unit has various air treatment functions, which can easily
realize various functions such as air purification,
dehumidification, humidification, refrigeration, and heating.
