Advanced Automotive Air Conditioning (Demonstration Unit) Manufacturer,Supplier and Exporter in India

Product Code : EL-TWL-13138
Jlab Export is a leading Advanced Automotive Air Conditioning (Demonstration Unit) Manufacturer,and suppliers in India

This demonstration unit shows how a car air conditioning system works and performs, in the classroom rather than in a vehicle. A variable speed motor lets the system run at different speeds. Its instruments give the readings for basic thermodynamic experiments and for troubleshooting under various operating conditions. It runs on 220 V, 50 Hz.

Experiments on the Demonstration Unit

Students begin by finding the parts of the system: the compressor, the condenser, the receiver-drier or accumulator, the expansion valve or orifice tube, and the evaporator. They then run the motor at low, medium and high speed and record the instrument readings at each step. This shows how cooling changes between idle and higher engine speeds in a car.

A Digital Psychrometer at the evaporator air outlet gives dry bulb and wet bulb readings, so the class can see how much the air is cooled and dried. Students use the instrument readings to plot the cycle on a p-h chart. Before the troubleshooting session, the teacher shows the inside of a compressor with the hand-cranked Automotive Air Conditioning Pumps (Sectioned).

Frequently Asked Questions

What parts make up a car air conditioning system?
A compressor driven by the engine through a belt and clutch, a condenser at the front of the car, and an evaporator behind the dashboard. Between them sit either a receiver-drier with an expansion valve or an accumulator with an orifice tube.

Why does the unit have a variable speed motor?
In a car the compressor speed follows the engine speed. The variable speed motor lets the class repeat that change in the lab and record how pressures and cooling respond from slow running to higher speeds.

How is it different from the Automotive Air Conditioning Trainer?
The Automotive Air Conditioning Trainer is a modular panel system for air conditioning and heating, with a wiring schematic, electrical test points and an interactive fault simulator. This unit is built for running performance, with a variable speed motor and instrument readings.

What power supply does it need?
It runs on a 220 V, 50 Hz mains supply, so it can be used in an ordinary lab or workshop without a running engine or exhaust extraction.

What do the pressure readings show about the charge?
On a car air conditioning system, low pressures on both sides usually mean too little refrigerant. The vent air then comes out warmer than normal. High pressures on both sides point to an overcharge or poor airflow over the condenser.
