With this type of flame supervision, the UV radiation emitted by gas or oil flames is used to generate the flame signal. The radiation detector is a UV-sensitive cell with 2 electrodes, which ignite when illuminated with radiation in the 190...270 nm range of the spectrum, thereby triggering a current in the flame detector circuit. The UV cell does not respond to glowing firebrick in the combustion chamber or to daylight.

The principle of air-conditioning compressor

Abstract: The air-conditioning compressor plays the role of compressing and driving the refrigerant in the air-conditioning refrigerant circuit. Air-conditioning compressors are generally installed in outdoor units. What is the principle of air-conditioning compressor? What is the reason why the air conditioner compressor does not start? How to replace the air conditioner compressor? The compressor is the heart of the refrigeration system of the air conditioner. The refrigerant circulation or flow in the system is achieved by the operation of the compressor. Once the compressor stops, cooling is over. The compressor compresses the refrigerant as<img src="{{media url="magefan_blog/The_principle_of_air-conditioning_compressor.jpg"}}" alt="" />
