Description
Technical field
The utility model relates to air conditioning for automobiles, refers in particular to the electric tramsmission frequency conversion bus vehicle top air conditioner device that adopts the scroll compressor self power generation.
Background technology
Popular bus air conditioner all adopts the open-type reciprocating compressor basically at present; divide active and two kinds of forms of passive type; all existing with long pipe runs carries compression working medium to roof; adopt types of attachment such as O type circle, exit skirt, flange because of its connection mode more; seal not good; easily produce seepage; the passive type compressor is that automotive engine drives; its discharge capacity and refrigerating capacity change with engine speed change; the idling poor refrigerating efficiency actively will use special-purpose diesel engine transmission, and its noise is big; diesel engine can not be shut down during defrosting, and oil consumption increases a lot.Compressor volume form is a piston type, and the about 70%-80% of its Volumetric efficiency difference belongs to opened compressor in the sealing, the axle envelope of using is by the oil film seal of sealing surface, easy to leak, the life-span is not long, moreover the condensation fan evaporation fan on traditional bus's air-conditioning all uses is direct current 24V power supply, blower fan is easy to wear because of rotating speed height, carbon brush, bearing is fragile, and the life-span is short, the maintenance frequency height, because it is influential to atmospheric ozone layer that its working medium is easily revealed, and is unfavorable for environmental protection.
Summary of the invention
The purpose of this utility model is improved at shortcoming that exists in the background technology and problem, and a kind of rational in infrastructure, maintenance convenience is provided, and adopts the efficient electric tramsmission frequency conversion bus vehicle top air conditioner device of scroll compressor.
The technical solution of the utility model is: the frame that the assembly that installs an air-conditioner is set at the passenger vehicle top, frame is divided three zones, regional both sides, a left side are symmetrical arranged evaporation fan respectively, the middle part is symmetrical arranged evaporator, right regional bilateral symmetry is provided with condenser, condensation fan is located at the centre of two condensers side by side, the zone line middle part is symmetrical arranged scroll compressor, both sides are provided with liquid vessel, described each several part connects into two covering devices with pipeline and auxiliary, whole frame is closed with vehicle with cap seal and is formed integral body, the power supply that the air-conditioning assembly uses is to drive the generating of secondary exciting generator after behind the rectifying and wave-filtering, send the inverter frequency conversion to import electrical equipment control assembly and air-conditioning assembly again and form the feedback interaction after the PLC machine is controlled and control by automotive engine.
The utility model computing machine optimal design, adopt two of present classic scroll compressors, make the vehicle top air conditioner assembly structure very reasonable, the duty volume is little, and is highly low, and maintenance is convenient, good looking appearance, scroll compressor is a kind of by the relatively rotating of fixed scroll body and moving vortex, and makes the body in fully enclosed space and changes and discharge the mechanical device of high pressure gas, and it has the height of effectiveness, stable action, the energy high speed revolution, biggest advantage is that volume is little, in light weight, be convenient to very much on automobile, install and use, reduce 4% with conventional reciprocating formula compressor specific volume, weight saving 15% is renderd a service and is improved 10%, and noise reduces 5db.
