804 sealed refrigeration training equipment

I. Introduction: 1, which is a special circulation circuit refrigerant flow controlled experimental device hermetic refrigeration training. 2, the device can be activated five system failure, convenient for students to practice (students through a variety of diagnostic and repair equipment failures to improve the ability to practice). Five types of system failures are: Compressor valve failure, system overload, the system due to load operation, the compressor discharge pressure is exceeded, the circulation pipe blockage. Second, the characteristics of the device: 1, can demonstrate a vapor compression refrigeration cycle process. 2, to strengthen the control of the refrigerant flow using a capillary seal circulatory system. 3, the device offers a variety of simulated faults. 4, optional accessories: experiments with student kits, experimental testing and maintenance tools. Third, the main configuration of the device: sealed air-cooled condensers, high starting torque hermetic compressors, pre-evaporator, tube-type filter drier condenser outlet temperature display device, high pressure safety switch, compressor and condensing the fan switch, system failure settings switch.
