A, air conditioning outside the big sound how
1, if the stability of the indoor unit installed is not good, when the air conditioning outside the operation of the unit, the copper pipe is connected to the indoor unit, the indoor unit is not stable enough, if you will be subject to compressor The indoor unit will be affected by the compressor if it is not stable enough, thus causing the indoor unit to **** vibration. Air conditioning indoor unit installation air conditioning indoor unit installation and outdoor unit connected to the connection problem also affects the timing of the use of air conditioning and noise.
2, the compressor noise value is very high, directly affecting the use of our normal users and rest. Therefore, the air conditioning compressor is one of the sources of air conditioning noise.
3, I think the main source of air conditioning noise is the air conditioning outlet, when the air conditioning is turned on the wind speed is too large, the air conditioning noise value is of course slowly become larger, which is one of the main sources of air conditioning noise.
4, the process of generating noise, air conditioning panel loosening when the long-term use of air conditioning, air conditioning panel is easy for various reasons caused by loosening, air conditioning in the operation of the vibration generated by the panel will make the panel friction each other.
5, air conditioning in the installation of the time will be carried out to test the machine, so just finished the use of the time there will be no obvious problems. But after a period of time with the noise may appear, not only affect their lives, but also easy to disturb the neighbors. The first thing you should consider is the looseness of the installation structure. Usually the outdoor unit is fixed on the wall with a set of simple tripod, if there is a loose, the compressor will make a very loud sound when running, and if not repaired in time, it may also lead to a greater danger.
6, the compressor is the core equipment in the air conditioning unit, the operation will produce a relatively large vibration. At the same time in the outdoor unit there are a large number of copper tubes, mainly for heat exchange. The strength of these copper tubes themselves are not very high, it is possible to run with the compressor to produce *** vibration, will also bring noise. The solution is very simple, just need to open the outdoor unit, and the copper pipe is properly reinforced, will be able to make the noise disappear.
7, air conditioning outside the big sound how, in addition to the installation of the problem as well as the equipment itself, there is a situation is simply aging, each air conditioning is a certain service life, to the age, each component will be deformed, the compressor will have a different degree of wear and tear inside, so the noise will become bigger and bigger. This situation does not have a good solution, you can carry out appropriate lubrication to reduce the noise, the most thorough method of course, or replace the brand new air conditioning.
The reasons why the air conditioner does not produce heat and the solution
1, the filter has dust:
As we all know, the filter will inevitably be stained with a large amount of dust after a long time of use, which is very easy to lead to the air conditioning in the heat can not be discharged in a timely manner, resulting in the air conditioning does not produce heat. For this reason, you need to clean up the dust and foreign objects in the vents in time, if not cleaned up in time, it will lead to a smaller amount of air and can not make heat.
Solution: Regularly clean the filter, which will help unclog the vents, so that the air conditioner can be normal heating.
2, air conditioning capillary tube or check valve problem:
It is similar to the human capillary, mainly by the outer diameter of 3.5 to 5 mm capillary tube and the outer diameter of 20 mm water supply circuit made. The check valve, on the other hand, is mainly due to the prevention of reverse flow of oil flow and air backflow. If there is a problem with these two, it will result in the air conditioner not producing heat.
Solution: Immediately replace the capillary tube or check valve, so that the air conditioning can be normal heating.
3. Outdoor temperature is too low:
Of course, if the outdoor temperature is low, it will also affect the normal use of air conditioning. Usually, if the outdoor temperature is low, then the indoor air conditioner will not be able to heat, because the air conditioner is unable to frost in this condition.
Solution: Use the special apparatus to clean up the frost on the air conditioner, so that the normal heating.
4, air conditioning fluorine:
If the air conditioning internal fluorine, then it will affect the heating or cooling effect. Today, most air conditioners are heat pump heating air conditioners, such air conditioners must utilize Freon to operate normally.
Solution: At this point you need to call a professional to fluoridate your air conditioner so that it can operate properly.
Service Commitment:
1. Door-to-door service in the city, no rest on Saturday and Sunday ?
2. Strictly in accordance with the appointment time door-to-door service, abide by the credibility, do not miss the appointment
3. Check first, after the presentation of the quotation, open and transparent, integrity of the service

5. Repair has been included in the door fee, the master door to door if the customer reasons to cancel the service, you need to charge 30 yuan to the door of the empty running fee, in addition to the price of this text, not as a reference basis for charging, not the actual transaction price, the actual transaction price by the master to show the unified charges shall prevail)

Air conditioning refrigeration:
Low-pressure gaseous refrigerant is sucked into the compressor, compressed into a high-temperature, high-pressure gas; and then, the gaseous refrigerant flows to the outdoor condenser, in the process of outdoor heat dissipation, and gradually condense into a high-pressure liquid; then, through the savings device to reduce the pressure (and also cool down) into a low-temperature, low-pressure gas-liquid mixture. At this moment, the gas-liquid mixture of refrigerant can play the air conditioning refrigeration "power": it enters the indoor evaporator, through the absorption of heat in the indoor air and continue to vaporize, so that the temperature of the room is lowered, and it has become a low-pressure gas, from the beginning into the compressor. So the cycle is repeated, the air conditioning can be continuous operation work.
The refrigeration medium will evaporate at low temperature and pressure, producing a cold effect; and condense at room temperature and pressure, releasing heat to the surrounding environment or cooling medium. Vapor at room temperature, high pressure condensation into a high-pressure liquid, but also need to reduce its pressure to the evaporation pressure before entering the container. Liquid vaporization refrigeration cycle is composed of four processes: vaporization of the work material, steam pressure rise, high pressure vapor condensation, high pressure liquid pressure reduction.
