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 is always part of the room, so that the cooling wind blowing in the room should be at; when heating should katabatic wind. So conducive to room temperature quickly and evenly. Weather turns hot, this air-conditioned and also come in great handy, however, air conditioning need to be careful of freon. It has been blown to pieces of the air conditioning unit, as well as the maintenance man was badly burned, which led to the accident reason is because freon add excessive pressure caused by excessive Xuzhou hand air conditioning parts, the air conditioning compressor explosion. Sheng Erda air conditioning maintenance: "The new Freon called '410A', so if you want to add refrigerant if air conditioning must be evacuated, if not evacuated, the air conditioning is great damage, easily blew up." Insiders told reporter, under normal circumstances, a qualified installation of air conditioning, in 3-5 years is no need to add freon, unless there is a refrigerant during use or transfer machine run drain phenomenon. But the real need for air conditioning freon people, Do not attempt to dismantle an air conditioner or add their own Xuzhou used central air conditioning renovation, should try to choose a formal air conditioning manufacturers designated service department and qualified maintenance workers. Sheng Erda air conditioning maintenance: "We must be reminded that the refrigerant is not a plus, the better, but more and more, then the price of second-hand air Xuzhou brand, its (cooling) effect is get out and normal, such as a The (air conditioning) plus six pressure Freon enough. "Day, 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, the wind and rain outside into the house to avoid second-hand air conditioning, 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. Xuzhou second-hand air transfer, Sheng Erda refrigeration, air conditioning used by Xuzhou 圣尔达 Refrigeration Electrical Services Limited. Xuzhou second-hand air transfer, Sheng Erda refrigeration, air-conditioning is used Xuzhou 圣尔达 Refrigeration Electrical Services Limited (xzktw.com) this year introduced a new upgrade, the above picture is for reference only, please call the contact or pictures on this page phone, for the latest information, contact: Liu Wanhai.
