AB Module For The Study Of  Heat-Transfer Thermodynamics Refrigeration Training Equipment Vocational Training Equipment

The experimental module mod. AB has been designed for an easy learning of the main physical phenomena pertinent to heat transfer, to the phase changes and gas laws, etc, that are all issues concerning the refrigeration and air conditioning cycles.
TRAINING PROGRAM
• Basic concepts of fluid thermodynamics: temperature, heat, work, power, enthalpy, phase changes
• Refrigeration cycles
• Heat transfer laws: conduction, convection, radiation. Heat exchangers
• The air psychrometric chart: dry-bulb and wet-bulb thermometers, absolute and relative humidity, enthalpy, specific volume
• Air transformations in the psychrometric chart
• Heat balances
• Refrigerant fluids and their pressure/enthalpy diagram
• Heat balances at the compressor, at the evaporator, at the condenser
• Assessing the system E.E.R. and the volumetric efficiency of compressor
• Analyzing the operation of a thermostatic expansion valve
• Calculation of condenser heat exchange coefficient
• This program also includes some exercises concerning the fault insertion (through the basic module)
