Air conditioning on the use of skills and operating guidelines may be many friends are very familiar with, and now there are many online air-conditioning technology to explain, perhaps many of my friends are half experts.But recently I saw online friends friends message said: I know that fixed-frequency air-conditioning air conditioner costs more than air conditioning, air jordan, why do people buy fixed-frequency air conditioning it? In fact, there are many features really need to popularize.
Although the inverter air conditioner has the advantages of energy saving, temperature control, advanced control, but because the price is more expensive, compared with ordinary air conditioning, about 1/3 to 1/4 higher prices, the same time, inverter air conditioner control system And the frequency conversion system is more complex, higher requirements on components, compared to ordinary air conditioners, inverter air conditioner failure rate is high, and, due to the use of frequency conversion technology, while in the frequency, there will be problems such as harmonic pollution so many friends do not Choose to buy such products.
In contrast, fixed-frequency air-conditioning market earlier, relatively mature in technology, so in our life there is a relatively large frequency is still fixed-frequency air conditioners. Our national grid voltage unity 220 volts, 50 hertz, Air conditioners working under these conditions are called fixed frequency air conditioners.
Benefit from simple working principle, fixed frequency air conditioning and cold and warm switching structure is also very simple, the compressor will be compressed into gaseous refrigerant liquid refrigerant at high temperature and pressure, and then sent to the condenser air conditioner is the outdoor unit, cooling After becoming a liquid refrigerant at room temperature and high pressure, the heat is exchanged to the outdoors.
After this, the refrigerant will enter the evaporator through the capillary tube is the indoor unit, as the refrigerant from the capillary tube to reach the evaporator after a sudden increase in space, the pressure decreases, the liquid refrigerant will vaporize to absorb a lot of heat, the evaporator Will be cold, the indoor unit of the fan blowing air from the evaporator, so the indoor unit is blowing cold air.
In addition the most important or cost-effective, fixed-frequency air-conditioning relatively speaking, the price of the store more modest, coupled with the impact of national energy subsidies to make energy-efficient air-conditioning products more affordable prices higher product cost .. To put it plainly is cheap, On this point by everyone's follow.
