Item Description

The trainer consists of:
Basic element components in automotive air conditioner unit ; automotive compressor, electric motor, dryer, high / low pressure gauge set, side glass, air cool condenser, finned tube evaporator with force draft fan, temperature controllers, ammeter and voltmeter.

The trainer is capable of simulating different engine speed (idler or full speed) conditions. It is controlled by digital frequency inverter. DC variable power source enables to vary the speed of the condenser and evaporator force cool fan. Consequently the students can gain trouble shooting experience in various conditions. On the trainer monitoring instrument side, there are four units of digital temperature controllers for user to view the high and low side critical points, two units of pressure gauge to observe the high side, low side refrigerant pressure. Side glass is provided for students to observe the refrigerant change state – from liquid to gas. DC ammeter, voltmeters are built in for students to understand the principles of controlling the DC motor speed by various applied voltages.
