MR025R Refrigeration Cycle And Heat Pump System Educational Equipment Refrigeration Laboratory Equipment I.Product overview The practical training device is used to study the operating principle and operation of the refrigeration heating and circulation system, and to study the operation of the four-way reversing valve and other components in the refrigeration heating system. The study uses intermediate media fluid (water) from the production site to the target transmission process. II.Feature Training platform adopts aluminum chassis frame type structure, the structure is simple and firm, in reducing the overall weight at the same time to ensure that the equipment of the overall strength, installed at the bottom of the four universal wheel, can be convenient to move. The refrigeration circulation line is installed on the equipment installation board. The high and low temperature area is painted with different colors to facilitate the observation and differentiation. The equipment has a good safety protection system. The refrigeration cycle is equipped with a high and low pressure protection switch, which can stop compressor work immediately when the system pressure is abnormal, and protect compressor and system safety. The electrical circuit is equipped with leakage protection switch, reliable grounding protection measures to ensure equipment and personal safety.
