I. Product Overview
This training equipment is designed to make students understand basic structure and working principle of domestic 2-door refrigerator, and learn operation method of domestic refrigerator.
II. Product feature
The training bench takes aluminum frame 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.
