The dual-mode inverter of air conditioning is with two inverter modes, applied in the air conditioning industry to meet the user's habits and needs, if the user does not use the air conditioning time is not too long, you can select the high-efficiency power-saving mode of operation through the dual-mode switching on the top of the remote control, to achieve power savings of 20% or more than the same specifications and the same energy-efficiency ratio of the single-mode DC inverter air conditioning, based on energy saving and comfort.
The mainframe of the inverter air conditioner is automatically stepless speed change, it can automatically provide the required cooling (heat) according to the room conditions; when the indoor temperature reaches the desired value, the air conditioner mainframe is able to accurately maintain the temperature of the constant speed of the operation, to achieve the "non-stop operation", so as to ensure that the ambient temperature is stable.
Domestic regulations of the voltage 220V, frequency 50Hz current rectified and filtered to get about 310V DC, this DC after inversion, can be used to control the compressor operation of the inverter power supply, which will be able to change the grid frequency of 50 Hz to 30-130 Hz, inverter air-conditioning is the use of an inverter compressor and fuzzy control technology air-conditioning, can be adjusted according to changes in indoor temperature. adjust the cooling speed according to the change of indoor air temperature.
For a 15-square-meter room, an inverter air conditioner adjusts the temperature 6 to 10 minutes faster than a fixed-frequency type. After reaching the set temperature, the inverter air-conditioner can again run at a low speed with only 10% of the power of the fixed-frequency air-conditioner to regulate the temperature minutiae loss and maintain a constant temperature.
Expanded Information
The dual-mode inverter air conditioner generally comes with microcomputer (computer) control. It detects indoor and outdoor signals such as temperature (indoor and outdoor temperature, evaporator temperature, condenser temperature, suction tube mouth temperature, expansion valve temperature, inverter opening heat sink temperature, etc.), fan speed, motor current and so on. And by the microcomputer to issue a fan, compressor operation speed, refrigerant flow, broad switching, safety protection signals.
These machines are equipped with electronic expansion throttling. It with the microprocessor issued signals, change refrigerant flow at any time, so its efficiency is higher than the universal use of capillary throttling. At the same time in the refrigeration mode, no frost trouble (frost does not stop). Therefore, the air conditioner will not blow cold air to make the room temperature drop when heating, like the ordinary machine in defrosting reverse pump reversal.
Inverter air conditioners can also be used normally in the 142-270 volt range of grid voltage, according to the temperature control instructions, in the continuous operation of the compressor will change the frequency, when the production of cold volume requirements of high-speed operation, and vice versa, low-speed operation.
Because of the inverter machine without frequent start-up high current impact, and has been working at low speed, and the first time only half an hour to reach the set value, so the power saving is obvious. That is, the cooling (heat) of the power consumption than the efficiency is much higher.
"Inverter" uses more advanced technology, the start-up voltage is small, can be started in low voltage and low temperature conditions, which for some areas due to voltage instability or winter indoor temperature is low and air conditioning is difficult to start the situation, there is a certain effect of improvement. It can also adapt to the cooling and heating needs of a larger area due to the realization of stepless speed change of the compressor.
