Rapidly-learned and easily-used object teaching refrigerator

Abstract

The invention discloses a rapidly-learned and easily-sed object teaching refrigerator. The refrigerator is characterized in that the liquid injection port of a compressor (1) and a stop valve (1) are respectively connected to a rapid joint (7) so as to be connected with a vacuum pump (14) and a refrigerant tank (150), a high-voltage end connection stop valve (110) is connected with an air coolingcondenser (3) through a change valve (13) and a tee valve (27), a lower-voltage end connection stop valve (111) is connected with an air cooling evaporator (5) through the change valve (13) and a lowvoltage relay (21) as well as the stop valve (112), the air cooling condenser (3), the tee valve, a filter, an expansion vale, a current meter and the air cooling evaporator are successively connected so as to form a loop; a refrigerating system with mutually converted water cooling and air fooling and a glass liquid view window are arranged in the teaching refrigerator, thus the interest of students in innovation and creation is effectively triggered, and the students can intuitively know the object principle; the refrigerator is simple to understand and essential, the aim that the students personally conduct design, manufacturing and operation can be met; and by using the refrigerator, the teaching difficulties are broken through, and teaching hours are shortened and simplified, therebyavoiding the waste of educational resources.

Description

technical field : [0001] The invention relates to a physical teaching aid for a refrigeration system, in particular to a quick-to-learn and easy-to-use physical teaching refrigerator, which provides students with the opportunity to operate on-site by themselves by visualizing the working conditions of each point inside and outside the refrigerator system, so that Students find it lively and interesting, easy to consolidate the knowledge they have learned, and lay the foundation for quickly learning the design of refrigeration systems and mastering the laws of refrigeration. This teaching aid belongs to the field of teaching instruments. Background technique: [0002] With the gradual warming of the global temperature and the improvement of people's material living standards, the refrigeration industry will become more and more [0003] popular, thus causing an increase in the demand for these technicians. Because the practice of teaching in our country cannot meet the ex...
