Product Description
GENERAL CYCLE REFRIGERATION TRAINER WITH DATA ACQUISITIO SYSTEM
This trainer introduces the student to the basics of refrigeration system used in refrigerator and air conditioning.
Students learn about practical knowledge of vapor-compression refrigeration cycle operation. The trainer contains
the basic components found in many refrigeration and air conditioning systems. These components have been mounted
onto a special frame and are clearly laid out and identified for student examination. During operation, studies of
pressure enthalpy (p-h) diagram concerning the thermodynamics cycle of refrigeration or air conditioning system can
be made. A number of special controls meters and transparent view ports have been provided in order to setup and
monitor a variety of experiments.
Features:
The trainer is built around a special work bench that incorporates a demonstration board onto which the components
are mounted. The components are neatly laid out in a manner similar to the refrigeration circuit so as to be easy to
understand. The refrigeration circuit is displayed on a colorful printed diagram. Refrigeration lines are color coded to
indicate the state of the refrigerant. Control panel with instrumentation including Line Voltage, Ampere (Total Current)
and Temperature display panel meters are provided as a standard to control the trainer and to facilitate
measurements. The unit is supplied with a experiment manual containing theory, standard operation procedure,
experiment procedures and references which should be provided during the bidding process to ensure all experiments
are met.
Components and System included:
A hermetically sealed compressor (air cooled), forced air condenser, forced air evaporator, 2 pressure gauges (high
and low), high pressure switch, low pressure switch, thermal expansion valve (TXV), Capillary tube, three sight glasses,
accumulator, filter/dryer, 5 hand valves, Instrument panel with system controls, voltmeter and amp meter, and 8
temperature measurement points with selector switch and digital display.
Education Objectives:
- Familiarization and operational functions of refrigeration circuit components.
