1.Brief introduction:-Rooftop air conditioner
Ruidong brand RWK series rooftop air conditioner were developed by our company,with continuous development and improvement.At present,we do not only have the conventional series with R22 as refrigerant, but also have the environmental friendly series product with refrigerant R407C,R134A or R404A,which are harmless to the ozonosphere.
This series product is horizontal packaged ones which consist of supply air,refrigeration,heating,humidity,air purification,and electric control section.The unit has the advantages of big refrigerating capacity,simplified refrigerating circuit,compact structure and etc.The unit can be installed on the roof and do not occupy much space.To ensure a precise temperature and humidity of supply air,the unit adopt computer controller.

Filters are to remove particles and contaminants of various sizes from the air. The type of air filter being used will very much depend on the application of the system.
Panel Filter is a flat and rectangular in shape and provides a minimum low efficiency filtration which is acceptable to the air conditioning industry. The high velocity filter is arranged vertically whereas the low velocity filter is arranged in V shape. Typical air velocity that moves through the filters is in the range of 2-3 m/s.
Heat Exchanger
Adopt high efficiency fin type heat exchanger with high quality internal thread copper tube and hydrophilic blue aluminum fin.
Scroll type compressor
(1) Flexible high-efficiencyscroll compressor which patent flexible design provides best ability of fluid-attack resistance and impurity tolerance.
(2) Continuous compression output ensure the pulse of air flow to bereducedwith low vibration noise
Evaporator fan
Direct-drive,forward curved,centrifugal-type fan, the shell and impeller were made from hot galvanized steel plate.Outer rotor motor was equipped for directly driving,which belt is necessary,ensuring long term and reliable running of air conditioner.
Condenser fan
Adopt famous brand axial fan compact structure which is accord with aerodynamic principles;falciform impeller which can assure it runs with high efficiency and low noise also can keep a better aerodynamic performance even under a short air inlet condition.
