ZM6305 General Cycle Air Conditioning Trainer with Reverse Cycle withHermetic Compressor Educational Equipment 1. Product introduction
This training device is used for in-depth study of ordinary refrigeration compression cycles. The condenser and evaporator have adjustable speed fans, which can intuitively reflect the refrigeration changes of the refrigerant under 4 different throttling devices under the same working conditions, and change the heat transfer effect of the condenser and evaporator through the fan speed adjustment. , Refrigeration change of refrigerant under different working conditions. Applicable to the teaching and training of skills appraisal, assessment work, refrigeration technology in higher vocational colleges, vocational schools, principles and maintenance of household refrigeration equipment, and maintenance of refrigeration equipment.
2. Device Features
(1) The training device system loop contains expansion valves and capillary throttling devices. The capillaries are divided into three different lengths. The system can intuitively show the impact of different throttling devices on the cooling effect when the system is running.
(2) Adjustable speed fans for condensers and evaporators in refrigeration systems.
(3) The refrigerating cycle pipeline is laid on the equipment installation board. The high and low temperature areas are painted with different colors for easy observation and differentiation. At the same time, a refrigerant-specific flow meter is used to observe the refrigerant flow in real time.
(4) The overall structure of the aluminum profile frame is adopted, and the pillars are 125 * 35mm special industrial aluminum profiles customized for mold opening. The surface is imported from the Netherlands ACZU powder spray treatment. 4 universal wheels are installed for easy movement.
(5) The equipment has a good safety protection system. High and low pressure protection switches are installed in the refrigeration cycle. When the system pressure is abnormal, the compressor can be stopped immediately to protect the compressor and the system. The electrical circuit is equipped with a leakage protection switch, emergency stop button and reliable ground protection measures to ensure that Equipment and personal safety. 3． Technical Parameters
