Maintenance cost of air conditioning fan leakage in Beijing

In case of sudden power failure, the power plug should be pulled out and the power supply should be turned on after a few minutes of power supply. The air conditioner must use special power socket and circuit, and cannot share the power line with lighting or other household appliances. The current carrying capacity of the conductor and the capacity of the watt hour meter shall be sufficient, and the plug shall be in close contact with the electrical components.

The power supply is not connected properly. In the use of some electrical appliances, if the electricity is not connected properly, there will be poor contact, electrical appliances can not be used normally, air conditioning is no exception, poor contact between the plug and socket, power supply wire aging and other reasons will affect the air conditioning compressor, resulting in its normal operation. Usually, the starting voltage of constant frequency air conditioner is 187 V, and the range of voltage fluctuation should be 198-242v. If the voltage is unstable, the air conditioner compressor will not start. Therefore, it is necessary to install a voltage regulator at home.

Why does it take a while before hot air comes out? A: the main reason is that our machine has been designed in a humanized way and the function of anti cold wind has been designed. When heating, there is a process of heat accumulation and improvement. If there is wind coming out as soon as the machine is turned on, it is also cold air. In winter, when it is very cold, people are easy to catch cold when they are suddenly exposed to cold wind. Generally, under normal conditions, the hot wind will come out after 3-5 minutes. The specific situation depends on the outdoor environment at that time.

Troubleshooting: after the refrigerant leakage, the refrigerant should not be filled into the system in a hurry, but the leakage point should be found immediately, and the refrigerant should be filled after repair. The refrigeration system with open compressor has many joints and sealing surfaces, so there are more potential leakage points. During maintenance, attention must be paid to finding out the easy leakage links, and finding out whether there are oil leakage, pipeline fracture, street relaxation and other phenomena at the main leakage points according to experience.

Use electronic scale to measure the amount of refrigerant on the air conditioner. In addition, the normal operation of the air conditioner can be judged by the normal operation of the air conditioner. The method is: after 15 minutes of forced cooling operation of the air conditioner. If there is condensate dripping from the drain pipe. It indicates that the air conditioner is normal, otherwise it means that the air conditioner is abnormal. All in all. Maintenance of air conditioning refrigeration system failure. In order to achieve better maintenance effect, the above items should be used for comprehensive judgment as far as possible. Because, the maintenance data of air conditioning circulation system is related to many factors, such as the old and new (efficiency) of compressor, the cleanliness of condenser, ambient temperature, humidity, wind speed, etc. If you do not consider the actual machine, environment and other conditions to repair, the final result may be not to achieve the best effect or repair at all.

In addition to the above, but also need to pay attention to a point! That is to check the air conditioning filter, whether dirty or not! If you turn on the air conditioner for half an hour and there is no heating effect, then look at the dust on the filter screen. If there is too much dust, the heating effect will be very poor! After all, the filters are dirty, and it's hard to pass the heat out! I can Daxing District Kelong air conditioning installation, disassembly and drilling telephone In order to clean out the filter screen, so you don't have to hire a decorator, the air conditioner in your home can also make heating, and it doesn't cost so much electricity!

Now, air conditioning as a necessity of home life, the popularity rate in China has been very high. Although, it is common sense that air conditioning will form secondary pollution if it is not cleaned, most people have already understood it. But when asked about air conditioning Tongzhou Kelong air conditioner installation, disassembly and drilling telephone How to clean to avoid indoor air pollution, consumers do not know the knowledge of cleaning air conditioning.

The refrigeration cycle system of precision air conditioning in heat pump room is shown in the attached figure Shunyi District Gree air conditioning installation, disassembly and drilling telephone Due to the great difference between refrigeration and heating state, it is often unreliable to switch the refrigerant flow direction only by electromagnetic directional valve. Therefore, one-way valve is often used in precision air conditioner of heat pump room to switch refrigerant flow safely and effectively. In the refrigeration cycle, the difference between high and low pressure is small, the throttling element is the main capillary, while the auxiliary capillary is short circuited by one-way valve; In the heating cycle, the one-way valve paralleled with the auxiliary capillary is not connected, and the throttling element is connected in series with the main capillary and the auxiliary capillary, which can increase the resistance of the throttling element, that is, increase the high and low pressure difference of the refrigeration system, reduce the temperature of the outdoor heat exchanger, and obtain more heat from the outside, so as to achieve the purpose of heating. When the one-way valve leaks, the high and low pressure differential pressure of the refrigeration system decreases, the temperature of the outdoor heat exchanger rises, and the heat obtained from the outside decreases, resulting in insufficient heating capacity. In case of normal refrigeration and insufficient heating capacity of the precision air conditioner in the machine room, the pressure at the low pressure side will rise and the differential pressure between high and low pressure will decrease by detecting the pressure during the operation of the system.
