Trolleybus Air Conditioner / Electric

The product adopts integrated design and is impact in structure and easy to install and service as its condenser, evaporator, compressor and electric control system are mounted on bus roof. The pipe line of the cooling system that is joined by all-welded means and the totally enclosed type compressor ensure the cooling system is clean and free from refrigerant leakage. The unit is equipped with a Copeland flexible enclosed scroll compressor whose energy efficiency ratio is as high as 2. 58 and volumetric efficiency over 95% (25% higher than a piston compressor). The heat exchanger uses rifle pipe, high - performance hydrophilic aluminum foil so that its heat exchanging capacity is improved by over 10%. Composite material, the case in streamline structure is elegant in appearance and features corrosion, vibration and impact resistance, heat isolation and electric insulation. The control system of the air conditioner employs the up - to - date static inversion technology and soft start mode so as to achieve stepless regulation of cooling capacity and save energy by 30% or over. The CPU control mode adopted features strong control function, high reliability and low failure rate. The system is equipped with complete safety system including protections against overpressure, underpressure, overtemperature, motor overheating, undervoltage, overvoltage, phase failure, etc. The air conditioner packaged unit for electric motor coach and hybrid-electric buses consists of enclosed Copland flexible scroll compressor, overhead head exchanger assembly, power inverter control system, etc. Soft start mode is used to achieve the safe and smooth operation of the air conditioning system. The above energy economical and environmentally friendly advantages are brought into full play. Environmentally friendly refrigerant R407C is used so that the system is more impact and energy economical. It is easy to install, operate and service.
