Lumped parameter methods are used.
Simulation Model :
It consists of refrigeration cycle, cabinet, ambient conditions and electronic control.
Refrigeration cycle:
Compressor, Hot-gas Tube, Condenser, Capillary tube, Fan, Evaporator, Suction Line Heat Exchanger, Gas Charge
Cabinet & Ambient Conditions:
PU thicknesses, outer dimensions, air ducts, ambient temperature
Electronic Control:
Thermostat, Fan motor, Damper control
Example-6 : Refrigeration system design by 1D simulations.

When the cooling system simulation model is created, impact of below parameters can be analysed.
This reduces testing time and expenses drammatically.
