1. Equipment Introduction
1.1 Overview
Air conditioning is an air conditioner, which is 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.
Air conditioning is divided into many types according to the cooling capacity demand, and commercial air conditioning is one of them. Compared with ordinary household air conditioners, commercial air conditioners generally require a larger cooling distance span. Ordinary air conditioners suffer very large losses when transporting cold energy through pipelines. If thermal insulation materials are used, the cost will increase. Secondly, compared with ordinary household air conditioners, the condenser and evaporator of commercial air conditioners use gas-liquid convection to efficiently exchange heat. This heat exchange method has a very high heat exchange efficiency compared to air cooling. Therefore, choosing commercial air conditioners is the best choice. It has low use and maintenance costs, large cooling capacity, and a large cold transport span.
MRB3714E2 commercial air conditioner training station is a teaching device that simulates commercial air conditioners. The training station can demonstrate the basic commercial air conditioning refrigeration principles and provide high-quality air conditioning skills training for students or staff.
