Ultralow-temperature refrigeration teaching equipment

Abstract

The invention discloses ultralow-temperature refrigeration teaching equipment. The equipment structurally comprises movable wheels, a connecting frame, a base, a radiator, a box door baffle, a lock hole, an interlayer plate, an inner wall, a box body, a temperature control box, a box door base plate, a box door, a heat insulation plate, a refrigeration pipe and a lock catch, and the lock catch isinstalled on the surface of the box door. The temperature control box is provided with a shell, an adjusting button, a temperature sensor, an emergency stop button, a display screen and an indicatinglamp; the shell is connected with the box body, the adjusting button is arranged on the surface of the shell; the emergency stop button is arranged below the adjusting button; the temperature sensor is connected to the left of the shell; the display screen is arranged on the right side of the adjusting button, and the indicating lamp is arranged on the left side of the display screen. The refrigeration teaching equipment has the beneficial effects that the temperature control box is arranged, so that the temperature of the refrigeration equipment can be freely adjusted, students can observe refrigeration effects at different temperatures, the students can better understand the refrigeration technology, and the learning efficiency is improved.

Description

technical field [0001] The invention is an ultra-low temperature refrigeration teaching equipment, which belongs to the field of teaching equipment. Background technique [0002] Low temperature, commonly known as cold, according to the regulations of my country's meteorological department, any strong cold air with a local temperature drop of more than 10 °C in 24 hours or a temperature drop of more than 12 °C in 48 hours, and the lowest temperature drops below 5 °C is called a cold wave. Low-temperature operations refer to operations in which the average temperature at the workplace is equal to or lower than 5°C during the production process. According to the temperature of the working place and the time rate of low-temperature operation, low-temperature operation can be divided into four levels, the higher the level, the greater the cold intensity. [0003] The prior art discloses an ultra-low temperature refrigeration teaching equipment with the application number: 201...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a kind of ultra-low temperature refrigeration teaching equipment to solve the problem that the existing technology has a single function, a simple structure, and cannot freely adjust the temperature of the equipment, and cannot demonstrate the refrigeration effect at different temperatures for students. Enable students to better understand refrigeration technology issues
