Simple Compression Refrigeration Circuit

Simple Compression Refrigeration Circuit

Product Code : JL-AE-10005

Simple Compression Refrigeration Circuit
Features and Description:-
The trainer features a simple compression refrigeration system.
Evaporator and condenser have been designed as a pipe coil with each end immersed in a water-filled tank.
The water simulates the environment.
A thermostatic expansion valve serves as expansion element.
Two manometers indicate the two system pressures on the high and low pressure sides.
On an additional scale on the manometer (or Adding thermometers), the evaporation temperature of the refrigerant is indicated.
Two thermometers measure the temperature of the water in the tanks.
This allows for calculations of the amount of heat removed from the environment (evaporator, cold water) and added to the environment (condenser, hot water).
A sight glasses is provided to allow free visual inspection indicates the aggregate state of the refrigerant upstream of the expansion valve.
Learning objectives and Experiments:-
Introducing the main principle of operation of the refrigeration compression system.
Key components of a refrigeration system (compressor, evaporator, condenser, expansion element).
Relationship between the pressure and boiling point of a liquid Learning about the main factors that can affect the refrigeration system performance.
Operation of a refrigeration system / heat pump.
Investigating the main principle of the thermodynamics cycle.
Simple energy balance.
Instructional material.
The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
Technical Specifications:-
Educational unit for providing a hand-on training of Apprenticeship for refrigeration.
Basic principles of refrigeration in a simplified model.
Common compression refrigeration system with compressor of piston type, evaporator and condenser (each in the shape of a pipe coil) and a thermostatic expansion valve.
2 manometers with temperature scale for the refrigerant show the values of the refrigerant on the high and low-pressure sides.
