Refrigeration and Freezing Stage Unit

Refrigeration and Freezing Stage Unit
Description of Refrigeration and Freezing Stage Unit for Science Lab Equipment Laboratory Instruments Manufacturers, Engineering Lab Equipments Manufacturers
This is part of the HSI training system for refrigeration and air conditioning technology. In combination with the base unit the operational model of a refrigeration system with refrigeration and freezing stage results. The model is plugged onto the base unit, secured using fasteners and connected with refrigerant hoses to become a complete refrigeration circuit. In refrigeration and freezing combinations evaporators are preferably connected in parallel. To increase the refrigeration capacity, evaporators are operated connected in series. Here different pressure levels in the evaporators can be used to obtain different temperature ranges for refrigeration or freezing.
Specification of Refrigeration and Freezing Stage Unit:
    Model of a refrigeration system to plug onto the base unit
    Training system with HSI technology
    Each refrigeration chamber includes: evaporator with fan (to recirculate the air) and heater to generate the cooling load
    Refrigeration chambers with transparent front
    Adjustable evaporation pressure controller
    Selectable expansion elements: expansion valve or capillary tube
    Operating modes of the system configurable via 5 solenoid valves
    Sensors to record temperature and pressure
    Operation of solenoid valves, fan, heater and fault simulation via software
