Days, the air conditioning cooling effect is not good on the disaster. Here to tell us something Yantai air-conditioning maintenance. 1, we should not be too far in the installation of the indoor unit and outdoor unit distance. 2, the general is the indoor unit is slightly higher than the wall of the bore holes some easier drainage 3, if you have to increase copper tube, be sure to set pipe insulation, or brass aging and cooling and heating effect will decline . 4. Select surrounding ventilation, heat a good location, try to avoid suffering Xishai, gas corrosion, smoke place. 5, plus snow should pay attention to how much to add, not more nor less. Much less a whole would lead to cooling and heating effect is poor. 6, air conditioning installed after the hole through the wall to remember the good use special clay seal, avoid the wind in the rain outside the house, wet walls. 7, the outdoor unit is installed securely to prevent loosening, otherwise vibration joints installed after the requirements for leak check with detergent water. Carrying capacity of the air conditioner should mount a small air conditioner unit weight of less than 4 times 1) load. Carrying capacity of the air conditioner should mount a small air conditioner unit weight of less than four times. Mount bearing capacity outdoor unit at least not less than 180. Air conditioner outdoor woven material should not be loose mounting surface (such as the old house brick, hollow brick, etc.) Wall mounting; Gangan loading conditions shall be limited skills wall installation, the answer points to consider mounting surface material strength and endurance and quantity of carrier to a mounting surface mount air conditioner factor Xuzhou hand air conditioning repair, reinforcement or take protective measures if necessary, in order to ensure safe operation and personal safety of the air conditioner. (2) lock. When the air conditioner is installed, connect its mounting surface and mount between the mounting bracket and the unit should be solid, stable and reliable, to ensure that the air conditioner installed does not slip, tip over or fall off. (3) rust. Steel mounting bracket and steel fasteners rust treatment should determine the basic methods of household air-conditioner common faults are: see, hear, touch, test, analyze. 1, see: careful observation of the various components of the air conditioner work, focusing on observation of the three parts of the cooling system, electrical system, air conditioning air system used, determine whether they are working properly. 2, listen: listen to power on whether the air conditioner compressor operation sound is normal, abnormal noise, the fan is running without noise, the noise is too big. The air conditioner in operation, under normal circumstances a slight vibration, noise smaller, generally less 50DB. If the vibration and noise is too large, possible causes are: 3, touch: touch the air conditioner parts feel its cold, vibrations, etc., to help determine the nature and location of the fault. 4, test: In order to accurately determine the nature and location of the fault, often use Instrument check the measurement performance parameters and status of the air conditioner. Such as the use of refrigerant leak detector to check for leaks; use a multimeter to measure the power supply voltage, the connection terminals for ground current and operating current to meet the requirements of Xuzhou waste recycling air conditioning, computer-controlled air conditioner, but also measure the potential of each of the control points It is normal and so on. 5. Analysis: After the results of the inspection of several means obtained, most can only reflect some local state. Is another link between the various parts of an air conditioner, influence each other, a failure phenomenon There are several possible reasons Xuzhou hand air conditioning repair parts, and a variety of reasons may also have trouble. Therefore, the local factors to conduct a comprehensive comparative analysis, in order to fully and accurately determine the nature and location of the fault. _ _ Sheng Erda hand air conditioning refrigeration air conditioning prices Xuzhou brand used by Xuzhou 圣尔达 Refrigeration Electrical Services Limited.
