Now go to the mall to buy air conditioners, shopping guides are enthusiastically recommend inverter air conditioners, the reason is - energy saving and environmental protection! Is the inverter air conditioner really saving electricity? Let's take a look! First, what is the inverter air conditioner Inverter air conditioner is actually an ordinary air conditioner + inverter compressor + inverter control system. Its refrigeration principle and structure are no different from ordinary air conditioners. The difference is that the inverter air conditioner main engine is steplessly variable, and it will automatically provide cold and heat according to the indoor temperature. When the preset value is reached, the inverter air conditioner can accurately maintain the set temperature running state, realize non-stop operation and ensure indoor temperature. stability. Second, what is the power saving principle of inverter air conditioner? 1. The inverter air conditioner adjusts the heart-compressor of the air conditioner at any time by installing the inverter. In short, the compressor of the inverter air conditioner does not open frequently, but has always maintained a stable working state. In addition to running at high frequency just after starting up, most of the other time runs at low frequency, and the power consumption is lower than that of fixed-frequency air conditioner; 2. The number of frequency conversion air conditioners is much lower than the fixed frequency air conditioner. The fixed frequency air conditioner consumes more energy when it is turned on. Compared with fixed-frequency air conditioners, AC inverter air conditioners save about 25% of electricity, and DC inverter air conditioners save about 50%. Figure 1 Refrigeration system Third, the power saving advantage of inverter air conditioner based on time The power-saving advantage of inverter air conditioners is based on long-term use. The longer the inverter air conditioners are opened, the more power is saved. This is because when the inverter air conditioner and the fixed frequency air conditioner are turned on, they operate at the maximum power because they have not reached the set temperature. Because the circuit and technology of the inverter air conditioner are more complicated, more power is consumed. After reaching the set temperature, The inverter air conditioner can greatly reduce the power consumption by adjusting the running speed of the compressor, and the fixed frequency air conditioner can only adjust the temperature by switching the compressor. Generally, the boot time is more than 5 hours to fully utilize the power saving advantages of the inverter air conditioner. If the boot time is shorter, it will cost more than the fixed frequency air conditioner! Figure 2 inverter motor All in all, the inverter air conditioner is of course power-saving, but it is still necessary to judge the amount of power saving according to the specific use situation, and the inverter air conditioner has the advantages of low noise, more precise temperature control, and more comfortable body experience. These advantages of inverter air conditioners are based on their working principle, using frequency conversion technology to control the compressor speed to achieve the purpose of controlling room temperature. Incidentally, the inverter circuit of the inverter air conditioner is quite different from the industrial grade inverter. As a kind of independent equipment, the frequency converter can be automatically controlled, energy-saving and speed-adjusting. It is widely used. In industrial applications, the energy-saving efficiency of the inverter is very high. So how is the inverter tested? It is necessary to measure the inverter and the variable frequency motor as a whole motor system, and measure the steady state electrical parameters, motor performance, and transient motor and driver parameters. For the test of variable frequency motor and frequency converter, the domestic ZLG Zhiyuan electronic MPT motor test system integrates the design of instrument design and system integration to realize the innovation of control precision, analysis precision and international standard support. It can realize the comprehensive measurement of the performance characteristics and control characteristics of the motor at the same time, and create the first comprehensive test and analysis equipment for the motor and the drive. For variable frequency motor and frequency converter, it can realize the measurement of steady state parameters such as power, efficiency, stall test and color temperature cloud diagram of the whole motor system, and can also measure and measure the transient parameters such as control response, load step response and load disturbance. , to meet the testing needs of customers in all aspects.
