DEMONSTRATION DEVICE FOR REFRIGERATION SYSTEM

摘要

A demonstration device for simulating the operation of a heat pump system comprising a schematic represention of a heat pump system, a plurality of lamps and associated electrical circuitry adapted to illuminate portions of the schematic representation to simulate the operation of the heat pump system in various modes of operation, and to simulate refrigerant flow and the phase state and temperature of the refrigerant at different places in the system, and associated explanatory panels for alternatively demonstrating the operation of the electrical circuitry of the heat pump system, or indicating the mode of operating of the system.
