Adjust cooling in the summer, the indoor unit as evaporator surface temperature is low, the moisture in the air conditioning When water freezes in the evaporator surface air conditioning inside the machine, brought together more after the formation of water. Condensate produced as a conduit to drain away. Similarly, in the air conditioning and heating, the air conditioning inside the machine during heating, the outdoor unit in the refrigeration, the outdoor unit temperature is low, it is also absorbing moisture in the air outside. But generally when heating low outdoor temperatures are relatively teach, condenser surface temperature is below 0 degrees, moisture in the air condenses into the condenser surface will freeze or frost after. And as time goes on, the more the more the knot. Thus, the air conditioning heating effect is getting worse. When Icy to a certain degree, air conditioning defrost program started west of central air-conditioning manufacturers to provide air conditioning and heating effects. Ice melts, it becomes water central air-conditioning, which is commonly known as the air conditioner outdoor machine "leaks." Air conditioning and heating when the outdoor unit leakage is normal? This sentence should be changed Which central air conditioning, air-conditioning and hot water when the outdoor unit is normal, but it should not leak to the outside. Because now like family with a small air-conditioning, such as the bottom of the wall unit, Guiji and other outdoor unit has a drain hole, it can lead to a drain can drain a place, but when the installation does not install it. Also note that some units currently defrosting of random, but also some automation, as well as the shutdown of the central air conditioning installation, regardless of that, all you do not shut down until the defrost is completed automatically resumes heating. Air conditioning is that we can not live without appliances, we often there are some errors in the use of air conditioning during use: Myth one: the refrigerant needs to be changed once a year Myth: air conditioning for a long time do not matter Myth: air-conditioned rooms without Replacing Myth: clean air just wash the filter central air-conditioning offer, Jingbian central air conditioning, Xi'an Hao Electrical and Mechanical Services provided by the Xi'an Hao Electrical and Mechanical Technology Limited.
