12. COMPANY PRODUCTS
 Compressors
 The compressor is the heart of any air conditioning
system.
 Sanden has the unique feature of being the only air-con
manufacturer in India to supply three different types of
compressors.
 1). Fixed Displacement

 Available in 80 to 150 cc configurations.
 Suitable for passenger car, MUV, SUV, Commercial
vehicles and heavy duty truck application.
 Available in 12V and 24V applications.
 SVL also offers 150 cc compressors for heavy dutytruck
application

13. COMPANY PRODUCTS
 2). TR-Compressors
 Uses a unique design with two inter-locked scrolls, one
is fixed and the other is movable.
 Gives continuous compression allowing operation at
very high speeds, whilst maintaining a compact size
and high volumetric efficiency.
 Scroll is a rotary compressor, suitable for low NVH
(Noise, Vibration & Harshness) & low power
consumption.
 Provides jerk-free, easy drivability.
 Available in 50cc, 70cc & 90 cc configurations.
 Suitable for up to 12000 rpm applications

14. COMPANY PRODUCTS
 3). Variable Displacement
 Wobble plate type, internally controlled variable
compressor containing 6 or 7 pistons.
 Offers superior performance, better drivability and
low Noise, Vibration & Harshness (NVH) across all
operating conditions.
 Available in 100cc, 125cc & 165cc configurations.
 Suitable for efficient cooling and low power
consumption application.
 Capacity of the compressor can be controlled from 6
% to 100%.
 Used in all high end vehicles like Skoda, Logan,
Maruti Swift diesel, Ford Fiesta Diesel.

15. HVAC Unit : Heating Ventilation Air- conditioning Unit
 Provide high degree of comfort and reliability,
supported by state-of-the-art technology.
 HVAC are designed according to vehicle
specific requirements.
 Applications are available as HVAC, only A/C
and only Heating units.
 Suitable for passenger car, SUV, MUV, LCV
and Heavy Duty truck applications.
 Are always dashboard mounted for small
vehicles.
 Special features: Electrically controlled HVAC
are available for few selected models.

16. Human Comfort Control
 The human body is a heat-generating
device. But in spite of all the various
metabolic processes taking place inside
our body, a constant body temperature of
98.6o F (Fahrenheit) is maintained.
 Our body is actually analogous to an Air
conditioner. It can maintain this constant
temperature principally by 4 methods:
Conduction, Convection, Radiation and
Evaporation.

17. AC System consists of the following parts
 Compressor
 CondenserAssembly
 Receiver Drier
 TXV ( Thermo Expansion Valve)
 Cooling Coil Assembly ( Blower &
Cooling Coil)
 Pressure Switch
 Hose & Pipes

18. HOSES & PIPES
 Hose and pipes are used in air-conditioning
systems for interconnecting the compressor,
condenser, receiver drier and cooling unit as a
close circuit
 Refrigerant gases with special characteristics
need hoses with special nylon internal coating
 All the hoses are connected by aluminium
pipes through end fittings
 Special features include low refrigerant
permeability, high bursting pressure and long
product life
 All joints contain shaft seals and pads.

20. The Desiccant
 A desiccant is a solid substance
capable of removing moisture from gas,
liquid or solid. It is held in place within
the receiver between two screens, which
also act as a strainer

21. Condenser
 The condenser receives the high pressure, high temperature
refrigerant vapour from the compressor and condenses it to a
high temperature liquid.
 The designs allows heat movement from the hot refrigerant
vapour to the cooler outside air. The cooling of the refrigerant
changes the vapour to liquid. Heat exchange is accomplished
using cooler air flowing through the condenser.
 Location : The condenser is usually located in front of the car’s
radiator. Refrigerant temperature in the condenser varies from
50o C to 75oC with pressures ranging from 10 kg/cm2 to 21
kg/cm2.
 Condensing of the refrigerant is the change of state of the
refrigerant from a vapour to a liquid. This action is affected by
the pressure of the refrigerant in the coil.
 Condensing pressure in an air conditioner system is the
controlled pressure of the refrigerant which affects the
temperature at which it condenses to a liquid, giving off large
quantities of heat in the process.

23. Receiver Drier
 Receiver drier is an important part of the air
conditioning system.
 The drier receives the liquid refrigerant from
the condenser and removes any moisture and
filters any foreign matter present which may
have entered in the system at the time of gas
charging.
 Receiver section of the tank is designed to
store extra refrigerant until it is needed by
evaporator. The storage of this refrigerant is
temporary and is dependent on the demand of
the expansion valve.

24. Evaporators
 PAF Evaporators
 Aluminium layer type evaporators.
 PAF (Plate and Fin) makes flexible
design possible with evaporators
becoming smaller, lighter and enhancing
performance with minimum pressure
drop for the specified air flow.
 Available in 50 mm width.
 Used in all latest generation cars.

25. Pressure Switch
 It is the safety device of A.C. system. This switch is used to
stop the compressor if and excessively high or low discharge
pressure in refrigeration cycle is detected by the diaphragm.
 Dual function pressure switch is used in the air-conditioning
unit.
 a)Low Pressure Cut out b)High Pressure Cut out
 If the low discharge pressure in the refrigeration cycle that is in
the condensing pressure of refrigeration decreasing excessively
because of gas leakage in the system while A/C is operating.
The L.P. Switch operates and disconnects the compressor.
 If the discharge pressure in the refrigeration cycle increases
excessively because of clogging or poor cooling of condenser
while ac is in operating, there is chance of busting of system
parts. The H.P. Switch operates and disconnects the
compressor and prevent any damage
