【 Weak current College 】 air-conditioning maintenance FAQ and answers 】

The heating effect is not good if air conditioning is working but feeling the heat, you should check whether the following questions: whether in accordance with the requirements regulating the operation of the controller, set the temperature and wind velocity is appropriate (appropriate temperature is 18-22 c °, wind speed set stroke); filter dust filters are very dirty (each half months cleaning filters); in the outlet may be obstructions; ambient temperature too low (temperature below-5 ° c); rooms with glass walls, Interior and exterior heat fast; check the supply voltage is too low (power supply voltage is lower than the air conditioning 198V does not work or effects decreasing). Air conditioning on outages frequent conditioner outages frequent reason: set the temperature and room temperature difference is too small; air conditioner inside and outside the machine around windshield objects; room insulation effect is good. These reasons are the cause of open down frequently, this is because when the indoor temperature environment and setting as well as the outdoor environment temperature difference in approach, this phenomenon is normal. At this point should be based on the desired ambient temperature, the temperature setting upward or downward adjustments as appropriate 3-5 ° c, could reduce air conditioning the start stop frequent phenomenon. Air conditioning air-conditioning voltage range constant-frequency operation, power supply voltage range is 198-242V, below the below do not start 198V. Inverter air conditioner operation, power supply voltage range is 198-242V, inverter air conditioner can start at ultra low voltage 150V, but not normal to use run (run by high-frequency frequency machine, power, current larger, lower power supply is too low voltage protection does not work). Air conditioning does not power on when air conditioning is not turned on, do the following: If the power supply there is electricity, whether power; power plug is in contact with the remote control battery is good; there is electricity, such as low battery, and emits the signal is weak, indoor unit not receive; remote control operation range is too large, signal attenuation is more serious, indoor receiver receiving bad. Check the treatment method: check the power supply voltage is between 198 ~ 242V; re-powered 3 minutes and then power on the machine; replace the remote control battery. Air conditioning long unused maintenance method for air conditioning in a long time without (off-season storage) before the maintenance, in the sunny State of air, system operation for half a day or so, so that air conditioning inside completely dry. Cut off the AC power supply, even if the air conditioner is in a stopped state, it will consume some power. Clean filters, wipe with a cloth Sassafras indoor and outdoor machine shell dust, conditionally available outdoor machine cover covered unit. In what circumstances require additional refrigerant air conditioning installation, in the normal operating temperature range (-7 ° c-+ 43 ° c), refrigeration and heating effect is normal, you do not need to fill air conditioning refrigerant, if you feel in a normal application temperature range, and contact with the manufacturers of home maintenance service. How to repair a remote control air conditioner long does not use the battery in the remote control, battery leakage to avoid bad remote control internal corrosion, remove the battery after show, with a pointed object, press the reset key. Remote control placed in from the Sun, it cannot have a backlog of articles. Avoid remote control surface oil and sweat. Do not throw kepeng remote control.
