<br> <br> <br> The so-called "inverter air conditioner" is the traditional "fixed-frequency AC" compared to the concept. As everyone knows, China's voltage is 220 volts, 50 Hertz, in which the conditions of .air conditioning as "fixed-frequency air conditioning". Due to the power supply frequency cannot be changed, the traditional fixed-frequency air conditioning compressor speed is essentially the same, depending on its constantly "open," compressor to adjust the room temperature, .its an open a stop between easily - at room temperature, and consume more power. By contrast, "inverter air conditioner" power converter changes the compressor, adjust the compressor speed frequency. Depending on how fast the compressor speed reaches room temperature control, temperature .fluctuations, the purpose of the small, low power consumption, its comfort. While the use of frequency control technique for frequency conversion air conditioning, automatic selection according to the ambient temperature of the heating, cooling and dehumidification operation modes, make room in the short .time up to temperatures and low-speed, low-power state to smaller temperature fluctuations, enables fast, efficient and comfortable temperature effects. <br> <br> Power supply frequency is high, the compressor speed, air conditioning and refrigeration (heat) .and the large amount; less frequent when the power supply, air conditioning and refrigeration (heat) in the small. This is the so-called "principle of constant-frequency". Inverter air conditioner is its frequency converter, inverter is the 1980s came .out of a high-tech, it passed to the current conversion for motor operation frequency of automatic control, put a fixed grid frequency 50 Hz to 30 to 130Hz changes frequency, so that the air conditioning had a new revolution. At the same time, .also enables power voltage range reaches 142V-270V, completely solved because voltage instability caused air conditioner does not work properly. Inverter Air Conditioner every time when you start to use, usually let air conditioning for maximum power, maximum air flow for heating or cooling, .fast approaching the set temperature. Because the inverter air conditioner operating frequency by increasing compressor, increases in temperature of heating capacity, maximum heating capacity may reach the same brand, same level air conditioner 1.5 times, temperatures can still maintain good heating effect. In addition ., General split machine only four-shift the wind speed can be adjusted by inverter air conditioner indoor fan automatically at run time, the speed will vary with the compressor working frequency in 12 crosspiece wind speed range, because the fan speed and ability to meet the .air conditioner is more reasonable to achieve low noise quiet running. When the air conditioning high power operation, fast approaching the set temperature, the compressor is in low-speed, low power state operation, only the power required to maintain the set temperature. This .will not only temperature stability, and protects compressor frequent stop letting the attenuation of life, and a significant decrease in power consumption, high efficiency and energy saving. <br> <br> "Inverter air conditioner" using more advanced technology, a small startup ., voltage, low voltage and low-temperature conditions to start, which for some regions due to voltage instability or winter indoor temperature is relatively low but air conditioning is difficult to start, have a certain effect. Due to the implementation of a compressor with continuously .variable, it can also be adapted to more large refrigeration heating needs. However, the "inverter air conditioner" price is usually a "fixed-frequency air conditioning up to around $", so to buy "inverter air conditioner", note the following .: <br> <br> A, DC inverter 48 per cent is generalize <br> <br> China Refrigeration Institute of experts pointed out that DC's two electrodes of polarity is fixed, there is only one flow of electric current, no alternative, .no frequency at all, on what frequency? current market promotion of so-called "DC inverter air conditioner" actually is DC air conditioning, it's DC drive technology is far better than FM technology. But the marketing personnel in order to take full advantage of .people's minds thinking-in, we unhesitatingly to it on the original frequency cap, then make a joke. <br> <br> According to reports, DC only after a voltage conversion, energy loss is less than FM conversion. In addition, because .the DC motor rotor is permanent, and save the three-phase AC induction motor rotor current consumption, so that from the power grid power supply to the motor that paragraph electrical efficiency than FM high speed mode, saving some energy. But individual manufacturers but for .this point of the internal control system of energy-energy for the whole machine to exaggerate, and 48 per cent of the energy-saving. Experts said the Festival energy not depends primarily on the refrigeration system design and configuration, depending on the size of the .coefficient of refrigeration systems. It is not difficult to see that the constant speed improvements to speed air conditioner air conditioner primarily to improve the way its Auto-adjust to enhance the quality of the machines, instead of saving energy. However, in particular, the .speed is just improve the quality of the air conditioner is running a Foundation, and the real improvement also depends on the matching of the refrigeration system. Adjusting system of cooling capacity of the critical part is throttling decompression components, if you do not remove it from .the constant damping by changed to adapt to the speed range, adjustable damping of electronic pressure reducing valve <br> (Expansion valve), then that would speed air-conditioners have little meaning or even superfluous consumption internal conversion of electrical energy required. Modern air .conditioning efficiency than conventional in 2.6 - 2.9, very little beyond 3.0. Therefore, the energy-saving 48 percent of propaganda is not exact. <br> <br> Second, the "Payroll frequency" is not a price which is lower costs < .br> <br> "Payroll frequency" air conditioning price than most "frequency" air conditioning low price around $ mainly reduced costs. First of all, now inverter air conditioners are basically double rotor, and most were imported compressors, and "Payroll frequency ."with Shanghai Hitachi single rotor compressor, this post probably cost money. Secondly, the throttling device is divided into two kinds, one kind is the expansion valve, a capillary. General fixed-frequency AC with capillary, inverter air conditioner uses the expansion valve .. "Payroll frequency" using capillary, capillary cost more than ten dollars, while the expansion valve is a two hundred dollars. Third, frequency converter, General inverter machine imported, "Payroll frequency" is made. This point, in addition to the cost .difference, there also exist on the frequency ranges and narrow. The fourth is "Payroll frequency" Is a single cold winter in frequency machine, do not use the common four-way valve is turned into a pass-through, a four-way valve .is more, these add up to an estimated cost reduced to 800 Yuan. <br> <br> 3. not to maximum cooling capacity as purchasing criteria <br> <br> Inverter air conditioner and general air conditioning in the selection is different. .In the purchase, according to the size of a room to determine the size of the power inverter air conditioner instead of to the maximum cooling capacity as their purchasing criteria. Because the inverter air conditioner not work long hours in maximum cooling condition, its maximum cooling .capacity is limited to a specific area of the room for a short period of time can reach of cooling capacity, but it is important to avoid in the area access. Experts suggest that consumers may (145-175) W m2 buy inverter air conditioner. .<br> <br> <br>.
