Module for the study of domestic refrigeration

AC/EV

The experimental module AC/EV is designed so that students can acquire the data characterizing the refrigeration cycle and relate them with the thermal characteristics of the products to be stored at a temperature of approximately 0 °C.

Training program

  • Basic concepts of thermodynamics and relevant terms
  • Domestic refrigeration operating principles
  • Refrigerant pressure-enthalpy diagram
  • The main components of domestic refrigeration: hermetic compressor, condenser, evaporator, filter. Different devices for flow control: capillary tubes and automatic valves
  • System operation with automatic valve or capillary tube
  • Checking the intervention of safety devices
  • Assessing the parameters of the refrigeration cycle and plotting them onto P-h diagram
  • Heat balances of compressor, evaporator, condenser
  • Assessing the system E.E.R. and the compressor volumetric efficiency
  • Differences between actual and ideal cycles seen on P-h diagram
  • Adjusting the automatic valve versus the characteristics of the product to be stored
  • Fault insertion tests (via the basic module) are also included.
