How much pressing refrigerant is added to a half horse Gree inverter air conditioner 410 ?

When the refrigerant is filled into the refrigeration system from the cylinder, the cylinder can be connected to the repair valve, or the intermediate joint of the composite pressure gauge can be filled. Open the small cylinder and turn it upside down, exhaust the air in the tube, tighten the joint, fill the refrigerant, and close the straight-through valve when the gauge pressure does not exceed. Start the compressor to suck in the refrigerant, and at the same time observe the frost formation of the evaporator, and stop the filling when the evaporator is full of frost or condensation.

An accurate method for determining the amount of refrigerant charged.

1. Measure pressure. The temperature of the saturated vapor of the refrigerant corresponds to the pressure one-to-one, and the corresponding evaporation pressure can be found if the evaporation temperature of the refrigerant is known. The gauge value for this pressure is displayed by the high and low pressure gauges.

Therefore, the pressure value of the pressure gauge installed on the system can determine whether the refrigerant charge is suitable.

When the air conditioner of R410A refrigerant is running, the low pressure is at and the high pressure is at the high pressure. When the air conditioner of R22 refrigerant is running, the low pressure is there, and the high pressure is there. 1mpa=。

Too low or too high pressure is the cause of the abnormal system. Extended Information: How does it work Inverter air conditioners are equipped with inverters, how does this inverter controller work?

The domestic specified voltage is 220V, and the current with a frequency of 50Hz is filtered by rectification to obtain a direct current of about 310V, and after the inverter, the direct current can be used to control the operation of the compressor The variable frequency power supply can be obtained, which can convert the grid frequency of 50 Hz into 30-130 Hz, and the inverter air conditioner is an air conditioner that uses inverter compressor and fuzzy control technology, which can be adjusted according to the change of indoor air temperature.

The pressure in summer and winter will not be too different, but the original high-pressure side changes the degree pressure side, and the original low-pressure side becomes the high-pressure side. If the air conditioner is running with R410A refrigerant, the low pressure is about the same; The high pressure is about the same. If the air conditioner is running with R22 refrigerant, the low pressure is about the same; The high pressure is about the same.

1mpa=。Too low or too high pressure is the cause of the abnormal system. The amount of refrigerant in terms of pressure.

If the air conditioner is running with R410A refrigerant, the low pressure is about the same; The high pressure is about the same. If the air conditioner is running with R22 refrigerant.

The 410A refrigerant of the inverter air conditioner is about kilograms. It is best to quantify the dosing with an electronic scale.

The amount of refrigerant is not absolute, but mainly determined by the amount marked on the nameplate on the air conditioner. Each brand of air conditioner has a different size, and the amount of refrigerant it fills is also different.

For example, the ordinary refrigerant R22 is already a 410 refrigerant, even if the air conditioner model is the same and the brand is the same, the amount it fills is not the same.

For the same R32 refrigerant, they can be filled in different amounts. Even if the air conditioner brand is the same size, the materials they live in are different.

Therefore, the refrigerant model of each air conditioner and the amount it adds should be filled according to the amount marked on the nameplate of the external unit. Moreover, the refrigerant cannot be mixed, and the type of refrigerant must be filled with what type of refrigerant must be indicated.

For a one-and-a-half-horse Gree inverter air conditioner, the fluorine of 410 needs to be increased to about eight pressures, and generally this one needs about nine grams.

Ask the after-sales master about this. They are more professional. Air conditioner, my family bought Haier's. The cooling effect is very good, the air supply distance is very far, the temperature in the house will drop down after turning on the air conditioner, and the sound is very small and quiet.

Before adding refrigerant, the leakage point must be checked, and the refrigerant should be added after the leakage point is treated.

It is a simulated azeotropic mixed refrigerant, and when the refrigerant is added, the refrigerant is guaranteed to be added in a liquid way.

There are 5 ways to add refrigerant after R410A leakage, as detailed below:

Method 1: The remote control enters the rated refrigeration mode, and when the compressor is turned on in the refrigeration mode, the temperature set by the remote control is 17; The remote control sets the wind speed to high wind.

Method 2: Use the remote control to enter the rated refrigeration mode and use the test board to check the exhaust temperature, the exhaust temperature is about 75-80 is more appropriate.

Method 3: Use the test board in the mode of open refrigeration to check the return air temperature and indoor tube temperature, and when adding refrigerant, t back = t tube + (1 - 3).

Method 4: Use the remote control to enter the rated refrigeration mode, run the internal fan for more than 20 minutes, observe the evaporator for uniform condensation as the best state, and the return air pipe for uniform condensation.

Note: The above methods must be completed at an ambient temperature of 0 degrees or more.

Method 5: When the external ambient temperature is below zero, it is best to add refrigerant by quantitative refrigerant. Try to persuade customers not to use air conditioners when the outside ambient temperature is lower than -10, and try to repair air conditioners before the spring peak season when the temperature rises.

When adding 410A refrigerant, there are mainly the following steps:

1.Prepare R410A refrigerant, pressure gauge set bifidometer, thermometer, current card meter, etc., corresponding to the air conditioner signage.

2.One end of the hose is connected to the R410 refrigerant cylinder valve, and the other end is connected to the middle joint of the bifidus table. Use the low-pressure side hose to connect the needle valve on the thick pipe valve of the outdoor unit, and open the fluorine bottle and the meter valve switch before sending a little air to exhaust the air, and then tighten it.

3.Turn on the air conditioner, set the "refrigeration" function, and set the temperature to a lower temperature (the fluoride should be set to the lowest in winter, and even the temperature control sensor head in the indoor unit must be heated). After the compressor rotates, open the R410 refrigerant bottle valve, invert the fluorine bottle, and then open the gauge valve, at this time, the 410A refrigerant has quickly flowed into the blister copper pipe.

After a few seconds (no more than ten seconds), close the gauge valve and wait for the air conditioner to run for a few minutes.

4.Hand touch the thick copper pipe of the outdoor unit, the thick pipe should feel very cold, and there is condensation, the temperature of the pipe should be between 5 15 degrees, and the addition of R410 refrigerant is completed (the low pressure in summer should not be exceeded.

In the process of operation and use of the air conditioner, once the freon is reduced or leaked, even if the other parts of the air conditioner can operate normally, the air conditioner cannot play the role of cooling and heating. When it comes to the question of how often to add freon to the air conditioner, what I want to say is that as long as your air conditioner is well sealed, no matter how long your air conditioner is used, there is no need to add freon, and the cooling and heating effect of the air conditioner can also be very good. If it is necessary to add freon to the air conditioner, it is also necessary to add freon to the air conditioner when the air conditioner is insufficient or leaked.

Users should not blindly say that freon needs to be added regularly when adding freon to the air conditioner, and this statement is unscientific.

General fluoride addition steps: when adding freon to the air conditioner, first open the bottle containing freon a little, so that the freon in the fluorine bottle flows out slowly, and then quickly connect the fluorine tube to the fluoride port of the air conditioner and tighten it. After that, the freon in the fluorine bottle Lu Shen will flow into the air conditioner.

Add fluoride in the state of the empty rock in the trembling operation state:

1. Turn on the air conditioner to make it run, and add fluoride in the refrigeration state of the air conditioner.

2. Find the fluoride port of the air conditioner, which is generally on the thick pipe of the air conditioner to keep it in a low-pressure state.

3. Unscrew the nut of the air conditioner, connect the fluorine tube, and open the fluorine bottle at the same time, then the freon in the fluorine bottle will enter the air conditioner.

4. In the state of air conditioning and refrigeration, fluoride only needs to be filled with 4MPa, that is, 4 pressures.

The low pressure is coming. Refrigerant filling needs to be carried out in the external unit of the air conditioner, and there is a valve for filling freon on the external machine, through which the method of filling freon can be realized, and the specific operation steps are as follows:

1. Open the valve of the air conditioner.

2. Connect the filling pipe.

3. Open the valve of the refrigerant cylinder.

4. Open the valve of the filling table.

5. Add to the gauge hand indication.

Precautions: 1. Wear goggles to avoid splash damage.

2. If the air conditioner is on the high-rise exterior wall, it needs to be operated by professionals.

Brand model: Midea air conditioner.

System: KFR-35GW

Inverter air conditioner 410 fluoride under normal circumstances 5 pressure, can not exceed 6 pressure, for inverter air conditioner, in the process of fluoridation operation, its low pressure needs to be controlled in kilograms to 5 kilograms, and high pressure needs to be controlled in 15 kilograms. No matter what brand and type of air conditioner, the pressure value when adding fluoride is based on this.

It must be noted that no matter what brand or size, the pressure of fluoride should not be higher than 6 pressures, and 5 pressures are enough under normal circumstances. At the same time, depending on the weather, the pressure is different. The outdoor environment pressure of 25 degrees to 30 degrees is basically around the pressure.

In addition, the following centralized methods can be used to determine whether the refrigerant is sufficient: synchronous monitoring of compressor bridge tremor current; Observe the condensation of the exhaust tube; Feel the air outlet temperature, etc.

Precautions for fluoridation of inverter air conditioner:

1. In the process of fluoridating the inverter air conditioner, someone must observe the change of the pressure gauge pointer at all times. After a period of trial operation, if there is no abnormality, it is normal. After fluoride is added, it can be checked with detergent to see if there is any leakage.

2. Normally, during the use of the air conditioner, if there is no lack of fluorine, it should not be added, and it should only be added after it is missing. Therefore, if the air conditioner does not cool, it needs to be judged to see if it is caused by a lack of fluoride. Sensitive defeat.

3. In fact, it is relatively simple to add fluoride to the inverter air conditioner, and for families with conditions, you can also add it yourself. However, it is generally recommended to let a professional person add fluoride, because the fluoridation equipment needs to be disassembled and assembled, so as not to be unable to install it back after disassembling it.

4. When the air conditioner is fluoridated, it will be displayed on the instrument after it is full, and the low pressure needs to be maintained in this process, and the fluoride port can be covered after the addition is completed. At the same time, it should be carried out in a refrigerated state during the fluoridation process, otherwise it is meaningless to add fluoride. After filling, the valve must be closed immediately, and the fluoride collection related work can be done.

The refrigerant used in Gree inverter air conditioner is R22 (fluoride Xiaolyon), and in the case of normal operation, the pressure of Gree inverter air conditioner (using R22 refrigerant) can refer to the following standards:

1.High Side Pressure: During the refrigeration cycle, the high side is placed in the outdoor unit, and the general standard high side pressure should be between 140 and 170 psi. [Click to enter the official website to learn more].

2.Low Side Pressure: The low pressure side is placed in the indoor unit, and the general standard low side pressure should be between 65 and 85psi.

It should be noted that these values are only approximate reference standards, and the specific pressurization standard needs to be determined according to factors such as the model, use environment and working status of the air conditioner. Therefore, in the actual operation of the Acacia Bird, it is necessary to make specific settings according to the relevant technical requirements.

Products and services are the most direct embodiment of enterprise quality management, and they are also the most direct way for consumers to recognize the brand. Gree Electric adheres to consumer demand-oriented, consumer satisfaction as the standard, and protects the interests of consumers to a greater extent.

How much is the high and low pressure of a Gree inverter air conditioner when it is working?

High pressure, low pressure. It depends on the ambient temperature. High pressure and low pressure, indicating high temperature or higher fluorine.

High pressure, low pressure, good refrigeration, means that the compressor is very new, and poor refrigeration means that the pipeline is blocked. High and low pressures are low, indicating a lack of fluorine. If there is no lack of fluorine, but the high and low pressure difference is small, it means that the Suiheng compressor is old.

It has nothing to do with the power of the air conditioner, no matter how many horses, the pressure is about the same. Different refrigerants, different pressures.

How much is the pressure of the air conditioner operation.

The operating pressure of the system varies greatly depending on the operating conditions, the type of air conditioner, and the working conditions. Take the use of R22 refrigerant in domestic air conditioning as an example: under the outdoor ambient temperature of 35 degrees, the indoor dry bulb temperature is 27 degrees, the wet bulb temperature is 19 degrees, the exhaust pressure is about 18, and the suction pressure is about the bar, and the gauge pressure.

Hot and cold air guess do adjust the inspiratory pressure lower, about; Water-cooled air conditioners have lower exhaust pressure, about. If the refrigerant of the air conditioner is R410A, the overall operating pressure of the system needs to be increased by about 50% on the basis of the refrigerant R22.

What is the pressure of Gree 1 HP inverter air conditioner running and not running.

When the R410A refrigerant air conditioner is running, the low pressure is about and the high pressure is about. When the R22 refrigerant air conditioner is running, the low pressure is about and the high pressure is about. The pressure is too low or too high, which is the cause of the abnormal system, I hope it will help you, please use it if you are satisfied. Thank you!

Different, R32 pressure is around, R22 pressure is around.
