Air conditioning units set by CJSC "GM-AVTOVAZ" provides several advantages

High quality and operation safety
High capacity and efficiency approved by tests in climate cells of Delphi and JSC "AVTOVAZ"
Minimum impact on engine power and dynamic
Minimum impact on fuel consumption
Main components of the air conditioning unit (compressor, evaporator and heat exchanger) delivered by Delphi and tested in accordance with GM standards, components suppliers certified according to ISO/TS standards applied to the automotive industry.
Approved durability tests guarrantee safety of operation and long service life to air-conditioning unit
Air conditioning unit installed in accordance to "GM-AVTOVAZ" Quality Standards
Delphi compressor with variable volume considerably increases capacity of air conditioning unit as compared to compressors with constant volume
Aluminum Delphi evaporator produced following the most state-of-art technologies provides maximum capacity and highest quality combined with minimum size and weight

Air conditioning unit is completely integrated in operation algorithm of engine controller
Engine adjustment includes the presence of air conditioning unit and allows minimizing the compressor load at start and acceleration
Variable volume compressor switches on very smoothly and invisible for driver's ear without regard to rotations and engine load
Variable volume compressor doesn't require cycling switching-off during operation connected with pressure fluctuation in the system. This favorably distinguishes it from widely used compressors with constant volume
Internal regulation system of the variable volume compressor enables to maintain required pressure in the system by being switched-on constantly (except for acceleration and start from place when short switching-off of compressor forced-produced in order to save engine power)

Air conditioning unit switch-on and -off as well as fans regulation completely carried by engine controller
Function of feedback from air conditioning unit to engine controller carried by pressure control devices
Controller tracks pressure changes in the air conditioning system
Controller allows or disables switch-on of air conditioning unit and switches it off under critical operation conditions (at low and upper limit of allowable pressure, critical temperature of engine cooling liquid). This enables to eliminate breakdown of high-cost components
Fans switch-on produced in sequential order depending on pressure in air conditioning pipeline. It decreases operation noise of fans especially by idle engine running (e.g. in traffic jam) and quick fluctuations within the system increasing efficiency of operation of air conditioning system.
