Detailed Product Description: | Household air conditioners have the advantage of independence, the economy. Its main advantages: 1, temperature control: ordinary household air-conditioning can also regulate the air temperature, but due to structural constraints, small air volume, air temperature and indoor air temperature difference, so that the indoor temperature distribution is not uniform Xuzhou precision air-conditioning maintenance, poor comfort; large central air-conditioning and air temperature difference is small, the temperature distribution, the comfort is good. And air conditioning of the kitchen can be achieved. 2, adjust the humidity: household air-conditioners are dehumidifiers, run over time, indoor air dry, skin discomfort. The Beijing area dry climate, central air can be pumped into the fresh air add humidity. 3, the suspension is filtered: dust suspended in the air is one sign of bad air, central air-conditioning system with supply and return air system, a large number of cold (warm) air blown from the outlet, turn each bedroom and living room The air is sucked back from the return air, return air built with high-efficiency filters, can filter dust. 4, increase fresh air: the need for 15-18 cubic meters of fresh air per hour Xuzhou Hisense air conditioning maintenance of telephone, in order to ensure health. Household air-conditioner just now widely used in air temperature regulator Xuzhou Hitachi central air conditioning repair, and to improve the air humidity, oxygen content and other indicators of powerlessness. With the increase of the air conditioner running time, indoor air gradually becomes cloudy, easily lead to upper respiratory infections. Filtration and purification of the above relying solely on measures of negative ions and so it is difficult to fundamental change. The most effective way to solve the problem is to replace the fresh air. Home central air conditioning with fresh air replenishing device can be introduced into new wind. 5, increase the aesthetics of the space-saving: home central air-conditioning in a unique position to save space and increase the aesthetics aspect. Now people are no longer confined to the room of requirements Ershiyiting, Sanshiyiting room, split-level room after another and so on. If the first with split air conditioning, more than three out of the machine must be installed, while apartments have outdoor unit installation location restrictions, not beautiful. At the same time, one in each room to hang the indoor unit is not the best looking, and central air conditioning only one outdoor unit, and can choose a variety of styles outlet, combined with the ceiling design, mounted on the roof. Each outlet can be individually controlled, arbitrarily adjust the room temperature. 6, home central air conditioning There are three types: water systems, wind systems and refrigerant system, the user can according to their residential characteristics, matching the different types of home central air conditioning. Air conditioning repair spike skills 1, air-conditioning does not boot, does not boot There are two kinds, the first is the power no response, [transformers, fuse, rectifier bridge] these things should be a pediatrician, and other important measurement 5V voltage is normal Most of such problems in the CPU for Crystal [next] can be resolved. There is also a plug-in buzzer sound, remote control can not boot [manual] basically is the first to receive bad LF receiver will not know, under the online search to find receiver board foot is easy, right, negative capacitance or board very wide that line, find other legs oh feet easily 2, air conditioning is not decent clock air-conditioning maintenance, some midnight call, cleaning receiver board, change or remove the receiver automatically switch basic You can pass to kill 3, start a few minutes or tens of minutes outside the machine automatically shut down, or outside the machine does not start changing the indoor pipe temperature sensor 4, the boot display various error codes, Ha ha ha, surely you can not remember all the air-conditioned bar code, I never remember the fault code, to teach you a trick, a test inside and outside cable. 2 detecting sensor measuring .3 .4 commutation supply voltage [380V electricity], check whether the off phase. Whether observe current and indoor and outdoor unit is too dirty, I believe that the general problem can be resolved. 5, boot the outdoor unit does not start or fan turn out only for beginners is generally bad capacitor, other problems more specific analysis. 6, boot a time compressor thermal protection, I believe this is the most difficult problem of all maintenance of air conditioning, according to the conventional solution to this problem is not normally the case confirmed that the normal cooling system and voltage, the best for the compressor, do not a waste of time, time is money, do not listen to a bunch of ways, some magazine said, I have used those methods, the success rate is very low, there is no need, and some people make it shorter capillaries, do not how to do, ethical issues, and the impact of air conditioning effect 7, there is a plug on the show after a fault code and run error code is not the same, Unplugged show the power or signal lines in general, motherboard problem. Running for some time displays general sensor problem. Q: Under what circumstances air conditioning is beginning to defrost? A: general US Air defrost enter have these types: The first entry conditions: 1, when about 5 minutes into the heating mode or defrost mode, depending on the outside machine coil temperature and the maximum difference between the indoor temperature to identify, finds time of 3 minutes. 2, when the above inner coil temperature and indoor temperature difference between 5 degrees and smaller than 3 minutes, 3, ensure that the compressor accumulated operating time more than 45 minutes, 4, the indoor coil temperature is less than 48 degrees, while meeting the four then entered a flower cream. The second condition: compressor total running time over 45 minutes, and run more than 20 minutes of continuous coil temperature is lower than the indoor temperature is 16 degrees 5 minutes into the defrost state. Third various conditions: compressor cumulative operation more than three hours of continuous operation over 20 minutes coil temperature is less than the indoor temperature is 16 degrees 5 minutes into the defrost state. Fourth various conditions: Outside air enters into overload and outside the fan stops, the outer fan next start continuous operation longer than 10 minutes, but also to ensure that the compressor total running time over 45 minutes or 20 minutes of continuous revolution indoor coil temperature is less than 48 then enter the state of defrosting. Fifth various conditions: outside the fan stops and two hours have not yet entered the defrost, the defrost forced entry.
