The use of air-conditioning in households is now widespread, and air-conditioning is an essential and important household appliances. The most common type of air conditioner currently being used, not only in the home, but also in enterprises. So what's the principle of frequency air conditioning?
The fac is an additional frequency transformer to the conventional ac structure. Compressors are the heart of air conditioners, whose rate of rotation directly affects the efficiency of the use of air conditioners, and frequency transformers are the control systems used to control and adjust the rate of compressors to keep them at optimal speeds, thus increasing the energy efficiency ratio (20-30 per cent more efficient than conventional air conditioners)。
The fac is equipped with a frequency transformer. How does the fac work? Domesticly prescribed voltage of 220v, the current of the frequency 50hz receives about 310 v direct currents by the current filter, which, after reverse transformation, can be used to control the operation of the compressor. This translates the frequency of the 50 hz grid to 30-130 hz, which is an air conditioner using the fcr compressor and fuzzy control technology that can adjust the speed of cooling depending on changes in indoor temperature. A 15 square metre room with a fac operating at a temperature of 6-10 minutes faster than the fixed frequency. When the temperature is set, the fac can operate at a low speed of only 10 per cent of the power of the oac to regulate the slight depletion of the temperature and maintain the state of temperature。
Variable air conditioners are generally micro-machine (computer) controlled. It detects indoor and outdoor signals such as temperature (e. G., indoor and outdoor temperature, evaporation temperature, condenser temperature, air intake temperature, temperature of the swelling valve entry and exit, temperature of the mutated frequency initial heat sheet, etc.), wind engine rotation, electric motor current, etc. It also sends signals of wind, compressor speed, refrigerant flow, wide switching, safety protection, etc. These machines are equipped with electro-inflation stasis. It changes the flow of refrigerants at any time with the signal from the microprocessor, so it is more efficient than the general use of catheters. Also, in the refrigeration mode, the frost-free (the frost stops). Therefore, air conditioners do not cool their room temperature down when heat is produced, as when a normal machine reverses a cool pump。
In recent years, the use of variant air-conditioning has become increasingly widespread, and the use of variant air-conditioning in life can improve the quality of life of people. As can be seen from the above presentation, the specific knowledge of the principles of variable frequency air conditioning can be drawn upon by interested friends or focus on other elements of the site。
