Details introduction
Equipment Overview
This device is a desktop model, with dimensions of approximately 1280 ( length) × 700 (width) × 1650 (height) .
It allows users to study and observe the various stages of the refrigeration cycle (such as coefficient of performance, superheating, and subcooling) through pressure-enthalpy diagrams and R-134a charts.
The refrigeration circuit includes high-pressure and low-pressure gauges, pressure switches, sight glasses, filters, dryers, thermostatic expansion valves (TEVs), etc.
The circuit includes a pressure sensor that connects to the instrument.
Four thermocouples are placed around the cooling circuit for temperature monitoring and to support calculations of possible overheating and undercooling.
Pressure and temperature can be measured around the refrigeration circuit.
The equipment is equipped with an LCD display screen to show all measurement parameters.
The evaporator and condenser coils should be submerged in the water tank.
The water tank should be equipped with a temperature sensor to clearly display the cooling or heat pump cycle.
Equipment configuration
(1) Learning to use pressure-enthalpy charts
(2) Determine superheat and supercooling
(3) Basic refrigeration cycle energy balance
(4) Determine the coefficient of performance (CoP)
(5) Determine the non-isotropic, isotropic, and volumetric efficiencies during the compression phase.
(6) The effect of heat source and heat sink temperature on COP.
(7) Compare the performance of the actual cycle and the inverse Carnot cycle.
