Regarding the problem of air conditioning, what are the problems in the use of air conditioning?

It should be that the voltage is insufficient for the air conditioner to protect the low voltage, you can use a multimeter to detect the voltage in this case, the general air conditioner is lower than 180 It is easy to have this situation, test it, if it is confirmed that it is a voltage problem, it is recommended to install a voltage regulator.

Probably the main gate tripped.

Original: The principle of heating and cooling of air conditioning.

Air conditioning heating and cooling are mainly mobile heat. When heating, the heat from the outside is moved indoors; When cooling, the heat from the interior is moved outside.

The heating of fixed-speed air conditioners is not ideal, and in addition to the heating of the air conditioner itself, there is also heating wire auxiliary heating. Inverter air conditioners only have the air conditioner itself for heating, and there is no heating wire to assist heating.

The energy efficiency ratio of the heating wire can only reach 1:1, that is, it consumes 1 kilowatt of electricity and produces 1 kilowatt of thermal energy. Air conditioners have the highest energy efficiency ratio of all heating products, which can reach 1:

About 3, that is, it consumes 1 kilowatt of electricity and can move about 3 kilowatts of heat, so the air conditioner is energy-saving and power-saving.

The principle of heating and cooling of air conditioning is to use the characteristics of freon condensation liquefaction and heat release, evaporation and gasification to absorb heat to increase and reduce the temperature of indoor air.

1. Air conditioning and heating

When the air conditioner is heating, the gas freon is pressurized by the compressor to become a high-temperature and high-pressure gas, which enters the heat exchanger of the indoor unit (condenser at this time), condenses and liquefies heat to become a liquid, and at the same time heats the indoor air, so as to achieve the purpose of increasing the indoor temperature. The liquid freon is depressurized by the throttling device, enters the heat exchanger of the outdoor unit (in this case, the evaporator), evaporates and vaporizes to absorb heat and become a gas, and at the same time absorbs the heat of the outdoor air (the outdoor air becomes colder). Freon, which becomes a gas, enters the compressor again to start the next cycle.

2. Air conditioning and refrigeration:

When the air conditioner is refrigerated, the gas freon is pressurized by the compressor to become a high-temperature and high-pressure gas, which enters the heat exchanger of the outdoor unit (at this time, the condenser), and the condensation liquefies and releases heat to become a liquid, and the heat is released to the atmosphere at the same time. The liquid freon is depressurized by the throttling device, enters the heat exchanger of the indoor unit (evaporator at this time), evaporates and vaporizes to absorb heat, becomes a gas, and absorbs the heat of the indoor air at the same time, so as to achieve the purpose of reducing the indoor temperature. Freon, which becomes a gas, enters the compressor again to start the next cycle.

Through the above process of liquefaction and gasification of freon, the heat is absorbed at the evaporator and transferred to the condenser for release, so as to realize the transfer of heat and achieve the purpose of heating and cooling.

Blowing a small wind is because you have turned on the parking cleaning in the car, automatic is 22 because you press and hold automatic, I generally adjust 26, and then there is a connection sign on the top, all synchronized to 26

There are three types of metric, imperial, and inverter-specific interfaces. Look at the styling you should be metric, try more.

Drip problem: According to the description, the biggest possibility is that when the air conditioner is moved and reinstalled, the tilt of the indoor unit is not right (the side of the water outlet is required to be a little lower than the other side, and the tilt angle is controlled at about 5 degrees);

Abnormal sound of the indoor unit:

It is more likely that when the machine is relocated and reinstalled, the refrigeration system is not vacuumed, resulting in a certain amount of air in the system.

Enough horses. The refrigeration capacity you need is sufficient), so there is still a margin.

Although some brands secretly reduce cooling capacity in order to exaggerate the energy efficiency ratio, the relative margin is not to be feared. Therefore, it is okay to choose any brand of air conditioner, and if you are not bad for money, you can consider high-end.

It is normal for copper pipes to have condensation, but when you say icing, whether it is coarse or thin, the ice of the coarse pipe may be deflated during installation, the ambient temperature is low, etc., the icing of the thin pipe may be poor fluorine, etc.

See if there is any problem with the hang-up, find them after-sales to check, if not, let them change. It should be possible to change it I also have that problem, they said it was normal, I bought 2 of the same one, called them, and changed it to hang up.

After the air conditioner senses the set temperature, the compressor will stop, and your air conditioner can shut down normally, indicating that the electronic control and refrigeration system should be normal. The indoor temperature sensor of the air conditioner is in the air inlet position of the panel, and the temperature of the test is correspondingly higher than that of the noisy fiber air conditioner, and you can set the temperature lower if you set 27 degrees to feel hot.

The pipe connected to the external machine and the internal machine is called the refrigerant pipe, which is to be insulated. You can wrap the tube again and you should be able to solve the problem of water beading. The problem of short circuits can be solved without water.

Hope it helps.

Usually, the heating air of household air conditioners is only put into use by the fan and heating grid of the indoor unit, and the refrigerant is not used.

The car air conditioner can only be cooled, and the heating is the waste heat of the engine, and I drove the water temperature too high again in the summer, and the pot was boiled, so I drove the car to the maintenance station with the warm air.

Fluoride is free, within the six-year warranty, Gree air conditioner manufacturers do not have free **! Hangzhou Gree Air Conditioning Service Center (0571 86772800 No. 441, Kaixuan Road, Hangzhou (3rd Floor, Zhejiang Material ** Center)).

You can check step by step, prepare (or borrow) a thick power cord, from the imitation of your master bedroom to the new air conditioner, the original air conditioner in the master bedroom is not on, to see if the new air conditioner can be turned on normally, after being sure that there is no problem, remove the spare power cord, focus on checking whether the socket and wire at the location of the new air conditioner are tightened, whether the cross-sectional area of the wire is enough (current carrying capacity), in addition, whether the capacity of your kitchen switch is enough, it is best to change a new 40A protection switch. This generally identifies and solves problems.

- Is the air conditioner malfunctioning? With my 7 years of experience in repairing air conditioners, I will tell you how to solve these faults, which should save you a lot of detours.

First: When the air conditioner fails, you can go to the [air conditioner failure** network] to inquire, down to the brand and model of the air conditioner. Universal remote control** query can go to the universal remote control area for inquiry.

When encountering a failure of the air conditioner, we must strictly follow the scientific procedures, and do not act blindly and disassemble at will when the situation is unclear, the fault is unclear, and there are countless in the heart. The consequence of this often amplifies existing faults, increases operating costs, shortens the normal service life of equipment, and leads to early scrapping of equipment.

The air conditioner is not refrigerated or does not refrigerate.

This problem is most common, and the lack of fluorine in air conditioners is the key.

When the machine is turned on, first touch the trachea and judge it by the temperature.

If it is cold, the speed of the fan may be low.

The inner tube scales and dust are cleaned or replaced.

If the inner tube is not considered cool, the thick tube may be flattened.

The return air temperature is not cool, and then touch the intake air to judge.

The air intake is cold and frosty, and fluoride is added to try again.

If the frost slowly disperses, it is a good decision to lack fluoride.

It is not difficult to see the aging of the press, and the lack of exhaust is the key.

Four-way gas is also commonly judged by fluoride collection.

High-pressure scales must be seen to be dirty, and they will be slow to refrigerate.

If you still don't understand, it is recommended that you go to the [Air Conditioning Fault **Net] basic knowledge area and take a look at the maintenance cases to get started.

I hope you get better and better, and the new year will be smooth, all your wishes will come true, you will be healthy, and your family will be happy.

- Finally, I wish you all the best in your work, fix the air conditioner as soon as possible, and live happily ———

Special attention should be paid to when using the air conditioner!

1. Adjust the temperature of the air conditioner to avoid overheating or overcooling. If the air conditioner is spent, it will be reduced.

2. Power saving.

10 or so;

Carefully clean the dust filter, after the dust filter mesh is blocked, the effect of cooling and heating decreases, and it should generally be cleaned once every two weeks;

Use the timer effectively, and use the timer when sleeping or going out to save power.

Do not block the air outlet of the outdoor unit, when the air outlet of the outdoor unit is blocked by objects, the cooling and heating effect will be reduced, and electricity will be wasted;

5. The windows are covered by curtains, such as covering the direct rays of sunlight in summer, which can save electricity.

6. Be good at using the wind direction, the wind vane is downward when the heating is adjusted, and the wind vane is horizontal when the air conditioner is adjusted, and the effect is better.

According to the general standard of 200W cooling capacity per square meter, 80 square meters should use 2 sets of 3 hp cabinet air conditioners.

If you can only install one, you can install one 5 hp cabinet machine, which requires 380V three-phase electricity.

The wires are made of square copper wires.

The switch uses a 25A air switch.

Domestic brands prefer Gree;

Mitsubishi Electric is the first choice for imported brands.

For such a large area of sports venues, refrigeration in summer is more important, so it is necessary to configure the cooling capacity according to 300 square meters, 90 square meters need about 27,000 watts, you can buy 4 sets of 6500 watts of 65 machines, put them on 4 corners, and the effect is good.

Helgel is beautiful, and the more economical and practical ones are Chigao and Oaks.

The single machine wire diameter is 4 square meters, which is relatively spacious and reliable.

The capacity of the air switch is 20 amps for a single machine.

It is best to install two three-horse air conditioners at both ends according to the structure of the house, and brands such as Gree and Midea can be. As for the thickness of the power cord, the two-phase electricity and the three-phase electricity are different, so you can consult the electrician for details. It is best to use a 10 square main line for two-phase electricity, 4 square for the split line, 4-6 square for the three-phase main line, and a square one for the branch line.

The main air switch should use 60A, and the extension can use 25-32A.

Article 1: Tightly closed doors and windows should not rely on air conditioning for a long time to raise and lower the temperature, and the windows should be intermittently ventilated to maintain indoor air circulation and avoid lack of fresh air.

Article 2: Without installing ventilation equipment, a negative oxygen ionizer and a ventilator are installed at the same time as the air conditioner is installed, which can deliver a large amount of filtered fresh air to the air-conditioned room.

Article 3: The temperature difference between indoor and outdoor is too large Do not adjust the indoor temperature too low in summer, and the temperature difference between indoor and outdoor should be 5 8.

Fourth: the equipment is not clean The air conditioner and dehumidification device should be checked and cleaned regularly, especially the filter screen should be cleaned on time, so that it can really play the role of filtering dust, germs and harmful gases.

Article 5: Do not set the temperature too low during daily use, so as not to affect the service life of the air conditioner in high-speed operation for a long time. It is best to set it in automatic mode, which can not only cool down quickly, but also save electricity.

Don't estimate, just do the math.

The load of the table tennis room is calculated according to 180kw, 180*80=14400kw, and 1440 divided by about 5 horses.

Therefore, it is best to choose a 5HP outdoor unit, and the number of indoor units with 380V square copper wire and 16A air switch is determined according to the specific conditions of the room.

The brand recommends not to use Midea, Haier, some brands of Texas Asia-Pacific, who uses who knows, don't make heat in winter, let alone cold, if the picture is cheap, there is no way.

1. It is best to install 2 sets of 5P machines, which are economical and practical, and installed diagonally.

A 5P machine with a cooling capacity of 24,000W, which is equivalent to a cooling capacity of 300W per square meter, is suitable for sports venues.

3. Use 4 square wires and 32A air switches.

4. In terms of brands, first-line brands are recommended to use Gree or Midea, and more economical brands such as Galanz and Zhigao are used.

It is recommended to use a Gree Midea patio machine series air conditioner (5P machine) for central installation, 6 square independent power cords, three-phase four-core wires plus grounding, and 40A air switches.

80 square meters are generally equipped with a 5hp or 2 sets of 3hp, as for the brand, if you choose Gree, if you choose a domestic brand, you can choose Mitsubishi or Daikin air conditioning; As for the wire, if there is a 380V power supply, it is recommended to install a 5hp air conditioner, with a three-phase five-wire, that is: 5*4 square millimeter wire, and the empty selection is 16A; If you use 220V power supply, install 2 sets of 3HP air conditioners, and choose 3*6 square millimeter wires for power supply together, and select 32A for empty opening; 3hp1 set of air conditioner uses a 3*4 square millimeter power cord, empty selection 16a, if you still have questions, just send me a message.

If you install one, choose a 5-horse cabinet machine, and if conditions permit, install two 3-horse cabinet machines.

A space-saving, 5 hp cabinet machine mostly needs three-phase electricity.

The two cabinets together are 6 horses, the effect is also good, 3 horses cabinet can use 220V mains, in addition, if one of the problems occur, the other can also be used; If there is a problem with a single 5 horses, there is only a waiting share.

Not to mention, Gree is the first choice, followed by the United States, at least 120 (5P), three-phase electricity, wires of more than 6 square meters (10 square is preferred), and 3 air open 60A (mainly considering that the starting current of the air conditioner is 3 5 times the rated value and designed).

4 horses, domestic can be, buy to see the power, whether it is energy-saving. There are special switches and wires for air conditioners, which are sold in the home appliance city. It is not good to put the top floor, the refrigeration pipe is not long enough, and it will affect the effect if it is too long.

The smallest five-horse, of course, is the big brand Gree, Midea, to three-phase electricity, the best three-phase four-wire with ground, ten square, more reliable. Put the top floor can, to lengthen the connection copper pipe.
