What is an inverter air conditioner? Is the air conditioner for automobiles inverter?

Inverter air conditioner is based on ordinary air conditioner, which selects a special compressor for inverter, and adds a variable frequency control system.

The so-called "inverter air conditioner" is a concept that is created by comparing it with the traditional "fixed frequency air conditioner". As we all know, the power grid voltage in China is 220 volts and 50 Hz, and the air conditioner working under this condition is called "fixed-frequency air conditioning". Because the power supply frequency can not be changed, the compressor speed of the traditional fixed-frequency air conditioner is basically unchanged, relying on its continuous "start, stop" compressor to adjust the indoor temperature, which is easy to cause the room temperature to be cold and hot between opening and stopping, and consumes more electric energy.

In contrast, the inverter of "inverter air conditioner" changes the power supply frequency of the compressor and adjusts the speed of the compressor. Rely on the speed of the compressor to achieve the purpose of controlling the room temperature.

There is no inverter technology in the car, and the car equipped with automatic air conditioning only stops working when the set temperature is reached.

Generally, the power of the car inverter is very small, and the power of the household air conditioner is basically above 1000W (there is about 1100W), it must not be able to withstand it, even if the power of the inverter is large enough, if you want to maintain the operation of the air conditioner, you need multiple large-capacity batteries in parallel to use (the car inverter generally has two voltages of 12V and 24V), and the car battery does not have such a large capacity to maintain the operation of the air conditioner;

It is better to understand the inverter air conditioner as a variable speed air conditioner, the operating speed of the compressor is changed according to the indoor temperature difference, so the refrigeration capacity is not the same, the compressor runs at high speed when it is just turned on, so that the indoor temperature quickly reaches the set temperature, and then runs at low speed to maintain the indoor temperature unchanged, and the power consumption at this time is very small. Therefore, the refrigeration and heating speed of inverter air conditioner is fast, the indoor temperature difference is small, and the comfort is good.

A car air conditioner is not an inverter air conditioner.

Inverter air conditioners are equipped with inverters, the domestic voltage of 220V, the frequency of 50Hz current through rectification filtering to get about 310V direct current, this direct current after inverter, you can get the inverter power supply used to control the operation of the compressor, which can convert the grid frequency of 50 Hz into 30-130 Hz.

An inverter air conditioner is an air conditioner that uses an inverter compressor and fuzzy control technology to adjust the refrigeration rate according to changes in indoor air temperature.

Inverter air conditioners are generally controlled by a microcomputer (computer). It detects indoor and outdoor signals such as temperature (indoor and outdoor temperature, evaporator temperature, condenser temperature, suction pipe mouth temperature, expansion valve inlet and outlet temperature, frequency conversion opening heat sink temperature, etc.), fan speed, motor current, etc.

And the microcomputer sends out signals such as the running speed of the fan and compressor, the flow rate of refrigerant, the wide switching, and the safety protection. This type of machine is equipped with an electronic expansion inter-throttle.

Classification of inverter air conditioners.

1. AC frequency conversion.

AC inverter compressor is used to adjust the voltage conversion twice, so as to achieve the purpose of power saving.

2. DC frequency conversion.

The use of DC digital variable speed compressor, only after one voltage conversion, similar to the DC motor, removes the iron loss in the circuit, so compared with AC frequency conversion can save 18-40% of the electric energy, thus reflecting the superiority of DC frequency conversion technology.

Inverter air conditioners are generally controlled by a microcomputer (computer). It changes the refrigerant flow rate at any time with the signal sent by the microprocessor, so it is more efficient than the common capillary throttling method. At the same time, in the refrigeration mode, there is no defrosting trouble (defrosting does not stop).

Therefore, when the air conditioner is heating, it will not blow out cold air to reduce the room temperature like the ordinary machine when the defrosting pump is reversed.

"Frequency conversion" adopts more advanced technology, the voltage is small when starting, and it can be started under low voltage and low temperature conditions, which has a certain improvement effect on the situation that the air conditioner is difficult to start due to unstable voltage or low indoor temperature in winter in some areas. Thanks to the infinitely variable speed of the compressor, it can also be adapted to the cooling and heating needs of larger areas.

There is no difference except for the low-voltage inverter, and the maintenance method and fault phenomenon are similar except for the power supply.

Air conditioning is the most common configuration of cars, is car air conditioning inverter or fixed frequency? The simple explanation is that when you turn on the air conditioner AC, the compressor starts to work, then the fixed frequency compressor is refrigerated according to the rated frequency, no matter how much temperature you set, the compressor will work according to the rated frequency, and the inverter compressor, according to the different set temperatures, the computer automatically adjusts the working frequency, and intelligently adjusts according to the demand. To know about automotive air conditioning compressors.

The power is provided by the engine, setting the same temperature at the fixed frequency is relatively more than the frequency conversion consumes more engine power, driving feels heavy in the vehicle, subconsciously will increase the throttle, resulting in increased fuel consumption, the same is true for the vehicle is not started, the computer will increase the amount of fuel injected to maintain the compressor work.

You have to understand what is frequency conversion and ordinary fixed frequency, the simple explanation is that when you turn on the air conditioner AC, the compressor starts to work, then the fixed frequency compressor Tong Xing brother is refrigerated according to the rated frequency, no matter how much temperature you set, the compressor works according to the rated frequency, the variable frequency compressor, according to the different set temperatures, the computer automatically adjusts the working frequency, and intelligently adjusts according to the demand. It is necessary to know that the power of the car air conditioning compressor is provided by the engine, and the fixed frequency is relatively more than the frequency conversion consumption belt under the same temperature, such as more engine power, the driving feeling of the vehicle is heavy, and the throttle will be increased subconsciously, resulting in increased fuel consumption, and the same is true for the vehicle not to start, and the computer will increase the amount of fuel injected to maintain the compressor work.

The economy is not optimistic, and everyone is tightening their monetary policy.

If you can save money, people's concepts are also changing to energy conservation and environmental protection, and manufacturers will seize the subtle psychological changes of consumers to optimize products to meet people's consumption expectations.

How can there be sales. Constant temperature type air conditioner, the air conditioner reaches a certain degree of coldness, and the compressor automatically loses power. and the temperature is higher than your air conditioning panel.

When the required temperature is required, the compressor starts on its own. The advantage is that the compressor is effectively protected and fuel consumption is saved.

The car air conditioner is a fixed-frequency calendar, and its manual air conditioner and automatic air conditioner are fixed-frequency, because the laughing car air conditioner does not meet the frequency conversion conditions, and if the frequency conversion air conditioner is used, some areas may not be able to start normally.

Car air conditioners are fixed-frequency, whether they are automatic cars or manual cars, they are fixed-frequency.

Car air conditioners are fixed-frequency, which needs to be manually adjusted, and the conditions for frequency conversion have not yet been reached, so they are not frequency conversion.
