The domestic refrigeration trainer allows to single out all critical components of the thermodynamic cycle and drives the student's attention to problems related to the frigorific gas which in domestic refrigerators is normally scarce, due to low convection in the areas where they are installed. For this reason, another convector was installed which can be series connected to the first one, in order to ensure excellent condensation even at extremely demanding working conditions.
Characteristics
The trainer is provided with a trolley and is designed for handy use in different environments. It includes:
industrial-like, connected and functioning components and instruments, easily accessible and visible. wide colour silk-screen painted panel which reproduces the whole circuit, with lamps and switches complete set of instruments, for operating data acquisition by-pass knobs for simulation and trouble shooting procedures safety devices: differential ground fault interrupter and usual installation protections.
Technical Specifications
silk-screen painted colour panel, with pilot lamp, assembled on an oven-baked painted steel structure 1/12 HP air-tight compressor double static wire condenser highly insulated cold store provided with a thermostatic probe, a thermometric probe and a static evaporator
5 detection valves
1 electronic digital thermometer, accuracy ±1% f.s., with 2 probes and 10 test holes located along the circuit for temperature assessment
