Scheme of management of KB system


Governing bodies

Work of KB system is supervised by means of the governing bodies located on the panel. The electromagnet of coupling of the compressor and the electric motor of the fan are connected by wires to the control panel. In the switched-off provision of a regulator the Electric chain вентилято ра is opened. Supply of air обеспечи is howled at regulator inclusion in one of four working provisions. The cooled and dried air arrives in car salon at inclusion maximum (MOVE), the normal (NORMAL) combined (BI-LEVEL) of modes or a mode обдува (thawing) of a windscreen (DEFROST). Air temperature is established by means of the rotary regulator located on the control panel. The handle of a regulator is connected by a driving cable to a mobile zaslonka on which situation the consumption of air through heat exchange a nik of a heater depends. When moving regulator from one extreme situation in another the hummock drive should provide a full range of movings of a zaslonka. The provision of a zaslonka of a regulator of temperature does not depend on the switch of operating modes. The driving cable of a zaslonka passes on the right side of the conditioner block. On some models of cars the zaslonka is supplied with an electric drive of moving, thus the cable is absent. On some cars the electric fan of system of cooling of the engine does not enter about Quarter system structure. That But less the fan automatically gets into gear at KB system inclusion in maximum (MAH), normal (NORMAL) or combined (BI-LEVEL) a mode. The fan starts to work at some cars and at mode inclusion обдува (thawing) of a windscreen (DEFROST). This feature of a control unit KB system allows to prevent an overheat of a head of the compressor. Thus the KB system works more effectively. On separate models of cars the electric fan of the engine is automatically switched off at achievement by the car of speed of 56 km/h when intensity of cooling of the condenser a running stream of air becomes sufficient. Operation of the fan the electronic block (EBU) via the fan relay operates.

Vacuum pipelines

Vacuum pipelines through a block are attached to the switch on the control panel by Quarter system. At violation of tightness or destruction of the separate pipeline it is unessential to replace all set of pipelines Enough to cut off a faulty site of the pipeline and to insert instead of it a plastic connecting tube. If it is necessary to replace all pipeline, it is necessary to cut off all pipelines from a block and then to attach them directly to the vacuum switch.

Vacuum receiver

At sharp dispersal of the car depression in the inlet pipeline of the engine decreases. Thus the return valve disconnects a vacuum receiver from the engine, providing possibility of normal work of a vacuum drive of management with Quarter system.
