BNGRUP

This trainer is introduced to the basics of the refrigeration and air conditioning. The trainer is a fully self contained and fully operational unit that includes basic refrigeration and air conditioning systems. These components have been mounted on special table-top frames and are clearly identified and identified for student examination. During operation, studies about the general cycle of refrigeration technology can be made. A number of special controls, meters and transparent view ports have been set up and monitored.

FEATURES: The trainer is a special work bench that incorporates a demonstration board onto which components are mounted. The components are neatly laid out in a manner similar to the refrigeration circuit. The refrigeration circuit is shown on a colorful silk screen diagram. Refrigeration lines are coded to indicate the state of the refrigerant. This bench may be mounted on wheels (W) for mobility. The unit comes with instruction manual and student job sheets. Power requirements are 220 VAC, 1 Phase, 50 Hz or alternatively 110 VAC, 1 Phase, 60 Hz.

COMPONENTS AND SYSTEM INCLUDE: A hermetically sealed compressor (air cooled), forced air condenser, forced air evaporator, two pressure gauges (high and low), thermal expansion valve (TXV) , high pressure switch, low pressure switch, 3 hand valves. Instrument panel with system controls, voltmeter and amp meter.

It is used to find the joule coefficient in the dry calorimetry experiment. Used with low voltage power supply, rheostat, measuring instruments, thermometer and plastic. The tools in the kit are: 1-aluminum housing 1 piece 2-shoe foam socket (two pieces) 1 piece 3-rubber ring 1 piece 4-resistance (47 ohm, ¼ w) 1 piece 5-resistance (68 ohm, ¼ w) 1 piece 6 -resistance (100 ohm, ¼ w) 1 piece

In physics, subjects related to motion are used when processed. The team is used after careful reading of the information on the experiments in the relevant physics book.

It is used where the forces must be measured. It is sensitive to 1kg-force capacity and 10g-force.
