1 How much environmentally friendly R32 refrigerant is added to the 5 hp Gree split air conditioner

R32 is one of the refrigerants currently used in air conditioning. Expansion: 1. Refrigerant, also known as refrigeration working fluid, is commonly known as refrigerant in some areas of the south, which is a working substance that is constantly circulating in the refrigeration system and changes through its own state to achieve refrigeration.

The refrigerant absorbs the heat of the cooling medium (water or air, etc.) in the evaporator and vaporizes, and in the condenser it transfers the heat to the surrounding air or water and condenses. 2. The working fluid that completes the thermal cycle in the refrigerator. It sucks the heat of the cooled object at a low temperature and then transfers it to the cooling water or air at a higher temperature.

In the vapor compression refrigerator, the working fluid that can be liquefied at room temperature or lower temperature is used as the refrigerant, such as freon (fluorine, chlorine, bromine derivatives of saturated hydrocarbons), azeotropic mixed working fluid (azeotropic solution mixed by two freons in a certain proportion), hydrocarbons (propane, ethylene, etc.), ammonia, etc.; In gas compression chillers, gaseous refrigerants such as air, hydrogen, helium, etc., are used, which are always gaseous in the refrigeration cycle; In absorption chillers, binary solutions consisting of absorbents and refrigerants are used as working fluids, such as ammonia and water, lithium bromide (molecular formula: Libr. white cubic crystalline crystalline or granular powder, highly soluble in water) and water, etc.; Steam jet chillers use water as a refrigerant.

3. The main technical indicators of refrigerant are saturated vapor pressure, specific heat, viscosity, thermal conductivity, surface tension, etc. After 1960, a large number of experimental studies have been carried out on the application of non-azeotropic mixed working fluids, and they have been used in the liquefaction and separation of natural gas. The application of non-azeotropic mixed working fluid single-stage compression can obtain very low evaporation temperatures, and can increase the cooling capacity and reduce power consumption.

Its properties are directly related to the refrigeration effect, economy, safety and operation management of refrigeration equipment, so the understanding of refrigerant property requirements cannot be ignored.

The amount of refrigerant perfusion of air conditioning depends on the value marked on the nameplate of the machine, and it is strictly required to be poured by weight. The perfusion volume varies from model to model.

The weight of the refrigerant, the rated current, if the weight is not marked, use the clamp meter to jam the current and add the refrigerant.

1. Under normal circumstances, it is necessary to add 5 pressures or kilograms of refrigerant to achieve the effect of refrigeration. 2. Of course, the specific amount should be added according to the cold coal quantity data marked on the nameplate of the air-conditioning product or in the manual. 3. Even if it is a round Li air conditioner manufacturer, the same number of air conditioners, different series of products, the amount of refrigerant filling may be different, and there is no rule to follow.

Related knowledge popularization: 1. R32 is a kind of refrigerant used in air conditioning, refrigerant is also known as refrigeration working fluid, commonly known as orange late refrigerant in some areas of the south, is a kind of working substance that is constantly circulating in the refrigeration system and changes through its own state to achieve refrigeration.

If there is no refrigerant in the air conditioner, the heat can not be exchanged effectively, and the air conditioner cannot be cooled or heated. 3. There will also be problems that cannot be seen on the surface, which will reduce the service life of the air conditioner, waste electricity, and damage the air conditioning compressor. 4. When the refrigerant is just added, the fluorine bottle needs to be turned upside down, and the time of one inversion should not be too long, and the cold air temperature of the pressure gauge and the air conditioner should be observed at all times, so as not to cause negative effects due to one-time addition.

It needs to be annotated according to the refrigerant amount data marked on the nameplate or manual of the air conditioner product. Simply speaking, air conditioners cannot give accurate data; Kilograms or so are enough. Therefore, the refrigerant should be determined according to the actual situation, and at the same time, it must be added by contacting a professional maintenance master.

What to pay attention to when using an air conditioner.

1. When turning on the air conditioner indoors, you need to wait for 10 minutes to expel the dirt inside the air conditioner, and then close the window. When going out for a short time, try not to turn off the air conditioner, and frequently turning the air conditioner on and off will not only fail to save electricity, but also consume more electricity.

2. When it is very hot, you can't blow the air conditioner all at once, so that the body has a process of adaptation. When the air conditioner is not in use, you need to choose the appropriate mode, such as the health mode, start the mode, and the air conditioner will automatically set the temperature, wind speed, and angle according to the actual situation.

5. When sleeping, adjust the mode of the air conditioner to the sleep mode, because when the human body is sleeping, the body temperature regulation ability will be reduced, and the room temperature will increase in this mode, and it will not be awakened in the middle of the night.

6. Choose the gear of the air conditioner according to your own needs. It is usually started by turning up the room temperature to a high level to reduce the room temperature to a suitable temperature, and later turning the air conditioner to a low setting to reduce noise and energy consumption.

7. Clean the air conditioning filter regularly, the air conditioner will accumulate dust inside the car after a long time, and clean the air conditioner frequently, which is conducive to everyone's health.

Dear I am happy to answer for you, my answer is as follows: The calculation method of Gree five-horse air duct air conditioner plus pipe quantitative addition of R32 refrigerant is as follows: 1. The standard for adding ordinary refrigerant for household air conditioners is not (R22, R410A), and if there is an extended pipe and the total length of the piping (A) is more than 5 meters, the refrigerant should be quantitatively increased according to the following table:

Liquid pipe diameter or 6 or transport ear 9 or 125 20m (A-5) 30g (A-5) 65g (A-5) 90g2, household air conditioner combustible refrigerant additional standard (R32, R290), connecting pipe more than 5 meters need to add refrigerant: refrigerant category liquid pipe or 6 liquid pipe or 9R32 (A-5) 18g (A-5) 45GR290 (A-5) 10g (A-5) 24g3, household ** air conditioning refrigerant additional standard: serial number liquid pipe diameter additional amount per meter (total length of liquid pipe1 A 22g2 A 54g3 A 110g4 A 170g Additional refrigerant Note:

The additional amount of refrigerant is calculated according to the length of the pipe diameter on the liquid side of the connecting pipe of the outdoor unit and the indoor unit; When the converted length of the divergent pipe is equivalent to the length of the piping, when the refrigerant is added to the system pipeline, the refrigerant tank is placed upside down on the electronic scale.

Summary. Gree five-horse air duct machine air conditioner pipe addition quantitative additional r32 refrigerant calculation method pro, as follows: 1, additional refrigeration dose r= piping refrigerant addition amount a + each module refrigerant addition amount according to different liquid pipe length, if a = diameter liquid tube length, b = diameter liquid pipe length, diameter liquid pipe length, d = diameter liquid tube length, e = diameter liquid pipe length, f = diameter liquid pipe length, unit m then the addition amount =, unit kg hope my answer is helpful to you, Finally, I wish you good healthand be in a good mood!

I don't understand. Keep it simple, okay?

Hello, the air conditioner is turned on and then weeps from the low pressure of the group, when it is added, you can do it, and then observe the refrigeration effect of the air conditioner. If possible, the high pressure should not be exceeded. When the air conditioner is deactivated, add fluoride from where it was added.

It is appropriate when the system pressure is reached. Let the air conditioner run for 30 minutes and do a careful inspection. The correct way to fill up, you must take your time when filling, let the air conditioner run for about 10 minutes after adding a little, and then measure the pressure and current, and then add it again and again, not to the pressure and current at that time as the standard, in that case, it may have been added too much.

When adding fluoride in winter, the four-way valve coil can be disconnected, and the indoor temperature sensing head can also be artificially made to reach a temperature that can control the cold to open the refrigeration. Sometimes it is also possible to let the air conditioner run in dehumidification mode, which does not have very high temperature requirements. I hope my answer is helpful to you, and finally I wish you good health and a happy mood again!

Can you tell me how many grams a meter of 32 media five horsepower air conditioners adds?

Hello, add is about 5kg, air conditioning is generally a horse to add to 6 8 pressure, the most important thing is to see the effect, it is best to add to the thick pipe to talk about the vertical reed water, or fiber shed to add to the gauge pressure (4 9 times, the surface contains with a bright refrigerant has been sufficient. I hope my answer is helpful to you, and finally I wish you good health and a happy mood again!

Hello, there are only two hose specifications for connecting the refrigerant tank and the needle valve, the coarse R410A and the thin R22; 2. When adding, release all the refrigerant in the system and re-evacuate the predetermined amount of supporting refrigerant; The method of adding fluoride to the air conditioner: 1. The air conditioner turns on the refrigeration and then adds fluoride from the low pressure, when it is added, it is OK, and then the refrigeration effect of the air conditioner is observed; 2. If possible, the high pressure measurement should not be exceeded; 3. When the air conditioner is off, add fluoride from the place where the fluoride is added. It is appropriate when the system pressure is reached. 4. Let the air conditioner run for 30 minutes and check carefully.

When adding fluoride, you must take your time, add a little and let the air conditioner run for about 10 minutes, and then measure the pressure and current. When adding fluoride in winter, the four-way valve coil can be disconnected, and the indoor temperature sensing head can also be artificially made to reach the temperature that can be refrigerated to open the refrigeration; Sometimes it is also possible to let the air conditioner run in dehumidified split wax mode, which does not have very high temperature requirements. 珞

1. Because the static pressure of the air conditioner has a very direct relationship with the ambient temperature, it is necessary to judge the draft according to the specific ambient temperature when the 5 HP air conditioner needs to add refrigerant, and under normal circumstances, the static pressure is how much R32 refrigerant needs to be added, which depends on the use of the specific air conditioner, and can be used as a reference according to the internal manual of the air conditioner or the nameplate on the external unit. 3. Even if the air conditioner of the same power is 5 horses, the type of refrigerant that needs to be injected is different, and the pressure will be different.

The maintenance methods of the air conditioner are:

1. Always check whether the ventilation duct is blocked, whether the sound is normal when the air conditioner is running, and whether the power plug and socket of the air conditioner are loose or fall off.

2. The air conditioner should be turned on regularly, and when the air conditioner is not in use, it is best to maintain the amount of one to multiple times a month, so that the core of the air conditioner is the compressor, if it is not used for a long time, the lubricating oil in the compressor will condense.

3. The filter should be cleaned regularly, and it is best to use the balance shed with a vacuum cleaner to suck it clean or wash it with clean water, so as not to block the air outlet with too much dust.

There are several reasons for the poor refrigeration effect of Gree inverter air conditioner:

It hasn't been cleaned for too long;

insufficient refrigerant;

The condenser is faulty;

insufficient number of horses; The ventilation pipe is too long, and the heat transfer efficiency is low;

The outside temperature is too high.

How to solve the problem that the refrigeration effect of air conditioning is not good in summer:

If you have a problem with the temperature setting of the air conditioner, you can set the temperature with the remote control, and it is recommended to set the temperature when cooling: 26-28 degrees Celsius;

If there is a lack of air conditioning refrigerant (freon), you can find after-sales service personnel to check and add;

Compressor problems can only be found by professionals for maintenance, or consider buying a new machine;

If the air conditioner filter is blocked, pay attention to cleaning the filter, and it is best to clean it once in about 15 days;

Do not place items at the air inlet and outlet of the air conditioner, otherwise it will affect the refrigeration effect of the air conditioner, and foreign objects should be removed;

The size of the room should be considered when choosing an air conditioner, and if the room is too large, you can also use a partition such as a curtain to reduce the room area;

If there is a heat source in the room that affects the refrigeration of the air conditioner, the heat source in the room should be kept at a certain distance from the air conditioner;

If the air conditioner is installed unreasonably, you can find the installer to reinstall and arrange;

If there is a quality problem with the newly purchased air conditioner, you can contact the merchant for replacement.
