811 advanced refrigeration training equipment

First, the device: 1, this equipment is a whole series of vocational training, the largest one, with good operability, and is provided with two evaporators were used to simulate the "fresh food compartment" and "freezer" driven by a group of semi-hermetic compressors. 2, the device is composed entirely of standard commercial components, and includes the necessary safety control components, all of the important components of the circulatory system are clearly visible in the experimental stage. 3, in a three-phase, the multi-evaporation cooling system, the device provides 25 kinds of refrigeration cycle failure and electrical failure for learning (diagnostic, confirmed excluded). 4, optional accessories: experiments with student kits, experimental testing and maintenance tools. Second, the device features: 1, demonstrates the same system in multiple work evaporators at different temperatures. 2, the system built 25 typical faults, button-activated design. 3, fault detection and localization. 4, 3-phase demonstration works.
