What to do in case of a trip Improper use of air conditioner can cause disaster

As soon as the air conditioner is turned on, the switch of this appliance immediately goes off. What is going on? Is there a problem with the wiring at home or the air conditioner? In such a situation, many consumers are often confused and do not know what to do At this time, experts have absolute right to speak.

　　Experts answer, there are two possibilities, one is the thermal protection of the press, and two, the temperature resistance of the inner tube is broken. If the press stops and the fan does not stop, it is the thermal protection of the press.

　　 (1) Cause analysis

　　①The fuse in the dedicated circuit of the air conditioner is blown, or the power switch is in poor contact, or the power supply is out of phase. At present, many users use one power supply in combination, and the power supply is abnormal due to abnormal operation of other electrical appliances.

　　②The power supply used by the air conditioner is too low. When the voltage is lower than 10% of the single-phase normal voltage (220V), that is, 198V or less, the refrigeration compressor in the air conditioner will be difficult to start.

③The dial button on the temperature controller has not been dialed to the proper position, such as dialed to a higher position, when the power is connected, the temperature in the air-conditioned room has not reached the upper limit of the set temperature (temperature at the starting point) , The compressor cannot start running.

　　④ The high pressure relay is activated. If the condensing pressure is too high, the high pressure relay will be activated to stop the compressor.

　　⑤ The low pressure relay is activated. If the refrigerant in the refrigeration system is insufficient, the suction pressure of the compressor is too low, and the low pressure relay is activated to stop the compressor.

　　⑥ When the current of the compressor or fan motor is too large, the overload protection relay is activated to cut off the power supply.

　　(2) Elimination method

　　① First check the cause of the blown fuse inside and outside the air conditioner, and take measures to prevent it from being blown out. It should be adjusted and repaired in time. It is recommended that families with air conditioners should set up a dedicated power supply, which can basically prevent such failures.

　　②If the local power supply voltage is often in a low state, a reliable power supply voltage regulator should be used. At the same time, it is recommended that households with more household appliances use a dedicated power supply.

　　③Set the dial button on the temperature controller to the required position, which is to adjust the temperature required by the air-conditioned room.

　　④ Check the reason for the excessively high condensing pressure and eliminate it to restore the condensing pressure to normal pressure.

　　⑤Check the cause of insufficient refrigerant in the refrigeration system, and eliminate it to restore the suction pressure to normal pressure.

　　⑥ Check the cause of the compressor motor and fan motor overload, and eliminate it; the heat pump auxiliary electric heating air conditioner uses both electric heating and heat pump auxiliary heating under heating conditions. The heating efficiency is high, and the electric power is between the heat pump type and the electric heating type. The disadvantage of the heat pump hot and cold air conditioner is that the four-way electromagnet directional valve used causes machine failure when the four-way electromagnetic directional valve fails. The four-way electromagnetic directional valve of the famous brand product has good working reliability.

　　 Electric heating type air conditioners rely on electric heaters to generate heat under heating conditions. According to the law of conservation of energy, 1kW of electrical energy can only be converted into 1kW of heat energy, and no more heat energy can be converted. For heat pump type air conditioners, if the coefficient of performance is 3, then 1kW of electric power is input, and 3kW of heat can be obtained. Therefore, under the same heating capacity, electric-heated air conditioners consume electricity. Users should note that if you buy an electric-heated air conditioner, the electricity consumption is estimated using the electricity consumption data under heating conditions, and the electricity consumption data under cooling conditions cannot be used, otherwise it will be too small.
