MRB3714E4 Split Air Conditioning Trainer Refrigeration Trainer School Laboratory Equipment Educational
1. Equipment Introduction
1.1 Overview
Air conditioning is an air conditioner, which refers to a device that uses artificial means to adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in a building or structure. Air conditioning has become an indispensable part of people's modern life.
The refrigeration principle of air conditioning is that the compressor compresses the gaseous Freon into high-temperature and high-pressure gaseous Freon, and then sends it to the condenser (outdoor unit) to dissipate heat and become liquid Freon at room temperature and high pressure, so the outdoor unit blows out hot air. Liquid Freon enters the evaporator (indoor unit) through the capillary tube. The space suddenly increases and the pressure decreases. The liquid Freon will vaporize and become gaseous low-temperature Freon, thereby absorbing a large amount of heat. The evaporator will become cold, and the fan of the indoor unit will blow the indoor air through the evaporator, so the indoor unit blows out cold air; the water vapor in the air will condense into water droplets when it encounters the cold evaporator and flow out along the water pipe. This is why the air conditioner will discharge water, and then the gaseous Freon returns to the compressor to continue compression and circulation.
MRB3714E4 split air conditioning training platform is a compressor refrigeration air conditioner. The training platform can demonstrate the basic refrigeration principle and provide high-quality air conditioning skills training for students or staff.
