Air conditioning in the running, the outlet air deflector how best location? Why? Cooling, wind deflector blowing up; when heating, the louvers downward blow. Because cold air is always part of the hot air in the room is always at the upper portion of the room, so that Xuzhou hand air conditioning parts, the wind should be blowing cooling; heating when the wind should blow down. So conducive to room temperature quickly and evenly. Air conditioning is not cooling after power is not heating, the crude pipe frosting quickly Symptom: After the boot does not cooling system used central air conditioning heat transformation of Xuzhou, crude pipe frost soon after shutdown, measured as 8Kg (due misjudgments pay more Freon ) Xuzhou second-hand air transfer, boot, rapid pressure drop to zero. Analysis: The boot lid inspection, found a four-way solenoid valve screw off, resulting in a four-way valve is not in place, the emergence of high and low string gas. Treatment: screwed to the four-way valve coil, that is to recover part of freon pressure is normal, the boot is working properly. After power-up, the compressor does not start 1. Problem: the temperature of the thermostat setting the thermostat too high or damaged answer: bring low temperature or replace the thermostat controller 2. Problem: Compressor capacitor damage answer: Replace Compressor capacitor 3. Question: Answer the master switch is damaged: Replace main switch 4. Q: Wiring wrong answer: rewiring 5. Problem: Compressor open or shorted answer: replace the compressor hand air conditioning, refrigeration Sheng Erda, Xuzhou central air conditioning recovery of waste by Xuzhou 圣尔达 Refrigeration Electrical Services Limited.
