Gree Qdi inverter air conditioner. Add R410. Shutdown pressure twelve kilograms. Ambient temperature

Static pressure when the air conditioner is shut down.

around 1MPa; The pressure rating is the pressure measured by the air conditioner under standard operating conditions, and the pressure of the air conditioner varies with the temperature.

Usually when the machine is stopped, its pressure is about 1MPa. Generally in the thirties of the time, the pressure of R410 is about 1MPa after equilibrium, the compressor thermal protection test pressure may not be measured, and the reason for the thermal protection of the fixed frequency machine is generally

1. Lack of air conditioning refrigerant;

2. The speed of the compressor is abnormal;

3. The capillary condenser is dirty plug or weld plug. The cause of thermal protection can be judged by looking at the air temperature, refrigeration effect, protection time interval, condenser temperature on the outside side, return air pressure, etc.

The press is not running when the pressure is between 30 degrees and MPa. The operating pressure is ...Now the air conditioner fixed frequency is generally R22

Normal! No problem! When the shutdown is generally between to abnormal, how much pressure is low, if it is still this pressure, it is your pressure gauge broken! Either this pressure is that you have an air conditioner.

Fixed-frequency shutdown operates in more than 20 in 4-5 thermal protection and shutdown pressure is the same.

A horsepower Gree inverter air conditioner can only measure the low pressure when working, but also depends on the model of the refrigerant, at present there are only two kinds of R22 and R410, the ambient temperature of R22 in the refrigeration state is 23 to 30 degrees is about megapascals, in the fixed frequency state. R410 is about to megapascals, in a fixed frequency state. And it increases with the increase in ambient temperature.

The professional after-sales master will not measure the high and low pressure of the inverter air conditioner too much, because this pressure is not a constant value, I don't know what the problem of your air conditioner is, is it to add fluoride?

The operating pressure of the air conditioner has nothing to do with the power of the air conditioner, and the high pressure is not fixed, the higher the temperature, the greater the pressure, the lower the temperature, and the lower the pressure.

The static pressure at 30 degrees is about the pressure when the fixed-frequency air conditioner is turned on, and the pressure at the highest frequency of the inverter air conditioner is about the left and right pressure, and the pressure will change due to the influence of temperature and frequency, the lower the frequency; The higher the pressure, the lower the current.

Remove the power supply of the reversing valve, let it actually work in refrigeration mode, and then add it from the thick pipe and fluorine. The 15 kg interface can't add fluorine, how can you add the pressure of your fluorine bottle if it's not as high as it?

Today I also encountered a 120 air duct machine, the situation is not much with this, the same is true for the four-way valve, the lowest voltage is one phase, the fluorine is over, the pressure does not rise, and the current does not rise. Only the press changer tried, because when the internal fan did not rotate, it took 5 minutes for the pressure to hit 28kg. Ask for a master.

When refrigeration and fluoride, low pressure is a few kilograms.

The low-pressure pressure is about 8kgf cm2;

The high-pressure pressure is about 22 24kgf cm2.

The inverter will vary depending on the environmental conditions; The frequency fluctuates at any time, before measuring the refrigerant pressure; It is recommended to set the temperature of the remote control at 27 degrees first, and after the system is slightly stabilized, measure the pressure of the refrigerant and the operating pressure of the R410A refrigerant with a composite pressure gauge

The low-pressure pressure is about 8kgf cm2;

The high-pressure pressure is about 22 24kgf cm2.

Too low or too high pressure is an abnormal phenomenon of the system, and the SI unit of pressure is MPa, which is about equal to 1MPa.

in between. Methods of fluoridation:

1. Let the air conditioner run and add fluoride in the refrigerated state.

2. In the state of heating, the wire of the four-way valve needs to be unplugged; Let the air conditioner run in a chilled state.

3. The fluoride port of Gree air conditioner is on the thick pipe, that is, low pressure.

4. Unscrew the copper cap with a wrench, connect the fluorine tube, and open the fluorine bottle, so that the fluorine will enter the air-conditioning system, and fill up 4MPa in the refrigeration state. As the saying goes, add 4 pressures.

5. The whole operation is carried out in the running state of the air conditioner.

According to the specific problem type, the steps are disassembled, the cause is analyzed, the content is expanded, etc.

Be sure to use **R410 to fill, so that the refrigeration effect is better, and it is worth noting that the remaining R410 in the original machine is evacuated with a pumping pump. The method of looking at the pressure gauge is different for each person, and it is normal to add a pressure of 8-9 kg.

Is R410A refrigerant vacuumed before adding? The low-pressure pressure of the inverter air conditioner during trial operation is 8kg, and the pressure under normal operation is times that of R22. When refrigerant is added, you only need to fill the liquid once according to the amount on the nameplate.

When the air conditioner is running at high speed, the low-pressure pressure can reach up to the high-pressure measurement and you are now only 7kg of the low-pressure measurement pressure, indicating that the refrigerant is still lacking.

Oh, I've been pumping all the vacuum for half an hour. I guess it's also a pressure gauge problem, is there a special pressure gauge for 410? Not the same as the normal one?

Buy Daikin, right? Fake ones add a lot! It's really quantitative! It's not expensive anymore.

I understand, I haven't added Buddha to the 410a machine.

I can't understand the temperature and pressure gauge of R410A in the overhead when the technician is level, and you have water in this title!

Look at the signage of the external machine, buy an electronic scale, quantitatively add, so that you can worry.

If it is an R22 air conditioner, the pressure will be around the right, and if it is an R410 refrigerant air conditioner, it will be around.

Is it a frequency conversion, the refrigeration you open or the heating, the refrigeration should not exceed the heating, it is hard to say, it is more than 2MP, I hope it will help you a little.
