Products characteristics: 1. High energy efficiency ratio design. 2.Light weight, reduce 80kg from deadweight compared with conventional products (take air- conditioner system matching up 12 meters bus for example). 3.Energy conservation, utilize noser from running bus, strengthen heat dissipation; 4.Low noise, providing much comfortable environment. tem Technical parameter Type DYZYD33DYZYD35Cooling capacity 28000Kcal/h30000Kcal/hType of vehicle10-12m Refrigerant R134aCompressorBITZERTwo device integrative typeTypeReinforced Fiberglas, Roof mountedCondenser Efficient gilled tubeFan Axial Evaporator Efficient gilled tubeFan CentrifugalAir intake control With fresh air mixture deviceMulti-air purify Activated carbon; ozone generator(optional fixing)Safety setting Pressure & TempAutomatic protection under abnormal conditionControl Cooling air volume adjustment L,M,H three step; Circular selection by soft toggle switchTemp control Automatic control from 15 to 30; show actual temperatureTrouble codeThe trouble of refrigerant pressure, voltage and sensor Item Technical parameterType DYZYD22Cooling capacity 18000Kcal/hType of vehicle8-8.5m Refrigerant R134a CompressorBITZERCondenser Type Reinforced Fiberglas, Roof mountedCore typeparallel flowingFan Axial Evaporator Type Fiberglas, Roof mountedCore type Gilled tubeFan Centrifugal Safety setting Pressure & TempAutomatic protection under abnormal conditionControl Cooling air volume adjustmentL,M,H three step;Temp control Automatic control from 15 to 30
