Space considerations
Effect on car performance
Environmental Impact Compressor
-Heart of the system, belt driven pump that fastened to engine.
-Responsible for compressing and transferring refrigerant.

-Two interleaved scrolls with involute geometry.
-One scroll fixed while the other orbits eccentrically to compress fluid

Very high volumetric efficiency (almost 98%)
Lesser Noise and lighter compared to rotary compressor.
-Responsible for heat dissipation

-The condenser is designed to radiate heat.

-Located in front of the radiator

-Require good air flow when system is in operation

-Plate fin type heat exchanger with micro channels used.

-Very compact and better heat transfer capability.

-Hot compressed refrigerant vapour cools at -constant pressure to liquid. Condenser
source PES Evaporator
-Heat absorption component.

-Used remove heat from the inside of vehicle.

-Secondary benefit - dehumidification.

-Unconditioned air passes through a filter before entering the evaporator.

-Plate-fin evaporator with micro channels used.
