Feature 1
1. Evaporator: Type Inner grooved copper tube and aluminum fin
2. Fin Type 5* :Slotted fin hydrophilic aluminum fin
3. Condenser: Type Inner grooved copper tube and aluminum fin
4. Fin Type 5* :Rippled hydrophilic aluminum fin
5. Condenser Fan Type: Low noise axial type
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.
