Midea / Gree explosion-proof air conditioning installation

(1) US / Gree explosion-proof air conditioning installation location recommendations
1. When the installation site causes the exhaust vent to be hit by a strong wind such as a typhoon, the exhaust guide should be installed at the outdoor air exhaust vent. The exhaust guide is only allowed to open to the outdoor unit.
1 unqualified, repair is not timely. The installation of the air conditioner is not in compliance with the regulations and is prone to accidents. For example, the metal casing of an electric device such as an air conditioner does not have a grounding device. Although there is a grounding device, the electric power is too thick or the grounding wire and the terminal are not necessarily connected or welded together; the power cord is arbitrarily changed, and the wiring or insulated wire is broken. Leather, the live part of the air conditioner is exposed; use unqualified electrical products (such as online cables, sockets) for installation; the installer is not a professional electrician or lacks electrical safety knowledge. I don't understand the technical requirements of electrical installation, etc., resulting in poor installation quality, unfavorable maintenance and repair, resulting in stability or danger. There is a possibility of electric shock.
2. During the operation of the outdoor unit, if a strong wind is hit by a fixed wind direction, a reasonable outdoor unit installation direction should be selected so that the outdoor unit blows out the wind direction at a right angle to the natural wind direction.
2 Pay attention to safety awareness during work. Some electricians are numb at work and have a weak sense of responsibility. They do not strictly follow the safe operating procedures and cause electric shock. For example, when the equipment such as a line or an air conditioner is working, the repair is started without an electric inspection; or when the air conditioner is repaired, when the air conditioner is not lit, it is considered to be powered off, and when the repair is performed without electricity, an electric shock occurs. accident.
Precautions
Explosion-proof principle After the aluminum alloy anti-explosion material is placed in the explosion-proof air conditioner, since the mesh in the stack of the explosion-proof material constitutes a honeycomb structure, the inner cavity of the container is divided into many small "small compartments", and these "small compartments" are contained. The spread of the flame, at the same time, the honeycomb structure has a high surface performance per unit volume, so that it has excellent thermal conductivity, and can quickly absorb most of the heat released by the combustion, so that the combustion reaction is finished. The temperature Tf is greatly reduced, the degree of expansion of the reaction gas is greatly reduced, and the pressure value of the container is not increased.
