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 the central air-conditioning pipe insulation, or brass aging and refrigeration and heat effect will be He declined. 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 to use special mastic seal Xuzhou central air conditioning repair parts, to avoid the wind and rain outside the house inside, 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. HIP me some central air plenum section of the installation of central air conditioning installed in the front of the indoor unit (the outlet side), and the other end is connected with the air duct, made of galvanized iron, containing foam rice. Its role is to stabilize the outlet pressure, eliminating the resonance and reduce wind noise caused by duct connection. More than a trailer unit of energy regulation mode controlled by a microcomputer Xuzhou professional air conditioning maintenance of telephone, the outdoor central air conditioning units inverter compressor according to the needs of the indoor heat load and automatically adjust the working status of the compressor. When cooling, the outdoor refrigeration compressor refrigerant vapor absorbed from the condenser, after transporting compressed gas refrigerant to the indoor unit. Each indoor unit through which the return air to the air intake Xuzhou central air conditioning recycling waste, post-heat exchange returned indoors, the room temperature can be adjusted. Central air conditioning maintenance air conditioner not cooling because abrupt? Air conditioning suddenly not cooling may have the following reasons: First, compressor thermal protection. (Just machines when the compressor temperature is not high, you can run it can be cooling, wait until the temperature on the high temperature to protect the compressor, and then outside the fan still working, so you think outside the machine is still working, the substance of the compressor has stopped a) The reasons for this failure are: 1. Cause 2. lack freon cooling outside the machine itself, the quality is not good 3. Compressors (new air conditioning that may be less) Second, the four-way valve is suddenly energized into heating a. Provided that: out of the wind is really hot. The reasons for this failure are: 1. 2.
