The microcomputer of the inverter air conditioner inverter air conditioner collects the information about the indoor environment at any time and compares it with the internal set value, and outputs the control signal after the operation. The working principle of the AC inverter air conditioner is to convert the power frequency AC power into a DC power supply and send it to the power module (high power transistor switch combination); at the same time, the module is controlled by the control signal sent by the microcomputer, and the output frequency is adjustable. The power supply (composite waveform is approximately sinusoidal) changes the speed of the compressor motor with the change of the power frequency to control the displacement of the compressor and adjust the cooling capacity or heating capacity. Let's take a look at the characteristics, advantages and related knowledge of the US inverter air conditioner.
A. Features
1 The starting current is small, the speed is gradually increased, and the starting current is 1/7 of the conventional air conditioner;
2 There is no problem of cold and hot, because the inverter air conditioner gradually reduces the speed as the temperature approaches the set temperature, gradually reaches the set temperature and maintains the low frequency operation balanced with the loss of the cooling capacity, so that the indoor temperature remains stable;
3 The noise is lower than that of the conventional air conditioner, because the inverter air conditioner uses a dual-rotor compressor, which greatly reduces the unbalance of the swing, so that the vibration of the outdoor unit is very small, about 1/2 of the conventional air conditioner;
4 The speed of cooling and heating is 1 to 2 times faster than that of conventional air conditioners. The inverter air conditioner adopts electronic expansion and throttling technology. The microprocessor can control the opening degree of the valve according to the information collected by the temperature sensor installed at the inlet and outlet of the expansion valve and the suction pipe of the compressor to achieve rapid cooling and heating. purpose.
Advantages
1 Energy-saving: Since the inverter air conditioner is equipped with a built-in frequency converter, the operating speed of the air conditioner's heart-compressor can be adjusted at any time, so that the energy can be used reasonably;
2 low noise: due to the balance of the inverter air conditioner operation, the vibration is reduced and the noise is also reduced;
3 high temperature control accuracy: it can control the cooling (heat) of the air conditioner by changing the speed of the compressor. The amount of refrigeration (heat) has a change range, such as the 36GW variable frequency cooling capacity changes to 360-4000W, the heat change is
300-6800W, so the indoor temperature control can be accurate to ±1 °C, making the human body feel comfortable;
4The temperature adjustment speed is fast: When the difference between the room temperature and the withering temperature is large, the inverter air conditioner is turned on at the maximum power, so that the room temperature rises rapidly or drops to the set temperature, and the cooling (heat) effect is obvious;
5 low voltage requirements: inverter air conditioner has strong adaptability to voltage, some inverter air conditioners can even start at 150-240V; 5 low ambient temperature requirements: inverter air conditioners have strong adaptability to ambient temperature, and even Start at a 15t ambient temperature.
US inverter air conditioner installation - the US inverter air conditioner installation precautions
1. When installing the US inverter air conditioner, it is necessary to use a vacuum method to remove the air in the system for the connected air conditioner refrigeration system. The specific operation is as follows. It is necessary to connect the manifold valve filling hose to the low pressure valve filling port (injection nozzle), and the high and low pressure valves should be closed at this time. Connect the filling hose connector to the vacuum pump. Fully open the manifold valve Lo (low pressure) handle and start the vacuum pump to evacuate. Usually, the time for vacuuming depends on the number of air conditioners. The larger the number of horses, the longer it takes. After pumping, you need to look at the pressure and fully close the manifold valve low pressure (Lo) handle and stop the vacuum pump. It takes a while to vacuum the vacuum to check if the system is leaking. Then slightly open the liquid valve to deflate to balance the system pressure to prevent air from entering when the pipe is removed. After removing the hose, fully open the high and low pressure valves. The last step is to tighten the high and low pressure valve bonnets and the filling port (filling nozzle) bonnet.
2. When installing the beautiful inverter air conditioner, it is necessary to pay attention to the internal and external machine wiring must use the special wiring of the inverter. All inverter air conditioners must be grounded reliably. If the user does not have a ground wire, it is necessary to propose a solution. When the air conditioner does not have a grounding wire, the common fault phenomenon is frequent shutdown and unstable operation. The outdoor unit of the inverter air conditioner must be installed in a place with good ventilation. Do not let the air conditioner work under low frequency conditions, and do not let the compressor work poorly. If the current is too large, it may stop. The connecting line must be equipped with a fixed wire clamp to avoid pulling off and breaking the connection. The joint must be firm and reliable. Otherwise, it may cause fire and other accidents due to fire; poor contact of the signal line may result in failure to open the machine or the compressor. stop.
