Xiaoshan Integrity Air Conditioning Repair, Relocation, Cleaning and Maintenance. Mainly responsible for: air conditioning relocation, Xiaoshan District air conditioning repair, professional maintenance, air conditioning fluoridation, air conditioning repair, air conditioning cleaning, air conditioning refrigeration, air conditioning maintenance. I now provide year-round installation, relocation, repair and maintenance for units, enterprises and individuals in Xiaoshan area, and clean all kinds of air conditioners and various refrigeration equipment
professional hanging air conditioners, cabinet air conditioners, and multi-split household air conditioners. It is recommended that everyone cleans them regularly Clean the dust on the condenser and evaporator coil of the air conditioner using a brush and vacuum cleaner . Note that when cleaning the air conditioner, the brush and vacuum cleaner should be swept in the vertical direction of the coil. Do not Clean in the horizontal direction to avoid damaging the fins of the coil. When the air conditioner is shut down for a long time (such as seasonal shutdown of the air conditioner), the air conditioner should be cleaned. After cleaning, only turn on the fan of the air conditioner and run it for about 10 seconds. Dry the inside of the air conditioner, and then cover the air conditioner with a dust cover.
Household air conditioner is a device with cooling capacity and centralized treatment of air: a device that directly provides processed air to a confined space, room or area, mainly including refrigeration and refrigeration systems and air circulation and Purification equipment may also include heating and ventilation equipment.
Household air conditioners are classified according to their functions: cold air type (single cooling type); heat pump type; electric heating type. According to the structural form: integrated air conditioner (such as window unit); split air conditioner (such as wall-mounted, ceiling-mounted, cabinet type, etc.)
During maintenance, the electrolytic capacitor must be discharged as follows. After the discharge is completed and before maintenance, please use the multimeter DC range to test the voltage between the two points of the discharge position to confirm that the discharge is completed to prevent incomplete discharge due to slow discharge speed or poor contact, resulting in abnormal clicks. If the voltage between the two points is less than 0.0, maintenance operations can be performed. It is strictly prohibited to directly discharge the electrolytic capacitor with a conductive object without adding a discharge resistor!
Touch the plugs of discharge resistor or electric soldering iron to the two points of the discharge position (sparks will be generated when first contacted), and hold for 30 seconds to discharge the electrolytic capacitor.
DC variable frequency controller hot ground problem:
The current variable frequency are all designed with hot ground. The ground of the weak current part (detection control output part) is not isolated from the strong current part. The ground of the weak current control part is also not accessible to people. Will get an electric shock! Therefore, the human body cannot come into contact with weak current parts
when running with electricity.
