Detailed Product Description: | 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 Xuzhou central air conditioning maintenance, the forced entry of the cream. Air conditioning and refrigeration installation air conditioning decline for several reasons not mind, craft mouth screw not tightened, causing refrigerant leakage. As long as this problem tighten the screws, and then make up the refrigerant line. Air conditioning dirty. If the air conditioner is dirty it will result in heat well inside and outside. Like this relatively easy to solve. As long as clean air will solve the problem. Air conditioning refrigerant shortage, will also affect the air conditioning and refrigeration. Since the cooling system leak participate within the system thermal cycling refrigerant (refrigerant) insufficient, resulting in decreased efficiency of heat exchange, resulting in insufficient cooling capacity phenomenon. This Just fill plus snow on it. After long-term use of air conditioning compressor aging, power increases, lower energy efficiency, resulting in performance degradation, such problems have no good way, only the air-conditioning system for processing Xuzhou recycling central air conditioning, changing the air filter, replace compressor oil. (Note: different grades, grade compressor oil Do not mix). If not, you can only replace the compressor or buy a new air-conditioning. How often required use of air conditioning and fluoride? When do I need to air conditioning and fluoride is not a limit for the time, and some air conditioning needs one to two years plus a fluorine, and there are a lot of friends will mistakenly believe that the summer air conditioning is not cooling is lack of fluoride , this is actually wrong, when air-conditioning use, clearly felt that the cooling and heating effect is not good, there may be insufficient F Lee Pleiades need fluoride, but not bad cooling and heating effect will certainly need fluoride can be resolved, It may be other reasons. 1: The outdoor unit may be dirty, thick dust, impact outside the machine cooling effect caused by bad, we often encounter such a situation in which the actual repair. 2: It may be badly clogged filter inside the machine, causing the machine can not evaporate Merry normal cycle, but there is no cold wind blowing. 3: internal air conditioning system may be clogged central air conditioning, caused by poor circulation, resulting in air conditioning cooling and heating effect is not good. Under normal circumstances, be able to exclude the above three cases, that it is necessary to fluoride air conditioning, and in order to work properly. Central air conditioning, refrigeration Sheng Erda, Xuzhou central air conditioning repair phone provided by Xuzhou 圣尔达 Refrigeration Electrical Services Limited.
