ZM6249 Faults simulation bench on refrigeration system Teaching Equipment

Product overview

The training device used for further study of common refrigeration compression cycle. Condenser and evaporator fan are with eight pieces of transparent pipe and fan which speed is adjustable, it can directly observe the condensation and evaporation process of refrigerant in the system, intuitive response under the same conditions of 4 kinds of refrigerants refrigeration change under different throttling device, and through the fan speed change of the condenser and evaporator heat transfer effect, under different conditions of refrigerant refrigeration.

Product feature

The training bench takes aluminum frame with cabinet structure, it is concise and fastness, it is not only to lighten the equipment, but also ensure the strength of equipment, it is equipped with 4 universal casters on its bottom, which is easy to move.

The refrigeration circulation pipeline is laid on installation panel, it is painted with different colors on high and low temperature area, which is easy for observation and distinguish.

The equipment is fitted with good safety protection system. It is equipped with high-low pressure protection switch in refrigerating cycle, when system pressure is abnormal; the compressor can stop work immediately to protect compressor and system. It is equipped with earth leakage circuit breaker, emergency stop and reliable ground protection in electrical circuit, which is to ensure safety of equipment and personal.
