1, the water cycle before the use of normal, but now found that the noise much larger than before, what is the reason? A: The aforementioned routine maintenance work on the water cycle is also related to this issue. We all know that there are very few impurities in the water, that is, distilled water can not be completely guaranteed after adding water tank. For the water cycle, the general temperature is set at 20 ℃, in particular, adapt to the growth and reproduction of microorganisms. After a long time these microorganisms will block the water filter caused by poor return, the pump will have a lot of noise. Sometimes these microorganisms are attached to the surface of the heat exchanger, resulting in deterioration of the heat transfer effect of the heat exchanger, resulting in a decrease in cooling capacity. Therefore, we must strictly follow the instructions in the routine maintenance work, regular cleaning of the tank, long-term deactivation, keep the tank dry. There seems to be a water leak in the water cycle, and sometimes there are a few drops in the ground for a while. Is there a local leak in the waterway? Generally speaking, the waterway will not leak during normal use. Relatively high temperature in the air when the relative humidity in the air is too large, water pumps in the water cycle, water pipe joints, external water pipe easily dew condensation, accumulated more later dropped to the ground, do not worry there is water Leaking place. If you are concerned about this, then open the air conditioning to reduce the room temperature or dehumidification can avoid dew. 2, the water cycle used more than a year are normal, but now the cooling rate seems slower and slower, the more obvious when the temperature is higher? A: The water cycle is simple to use, but regular maintenance can not be ignored. There are many problems that appear to be malfunctioning, which is caused by the fact that there is no regular maintenance. The electrical power of the water cycle and the heat that the refrigerant takes away from the load need to be dissipated from the radiator at the front vent hood and if the front vent hood is full of dust and willows, it will prevent the heat from dissipating Greatly reduced. In general, under normal conditions of use cooling capacity decline is due to ventilation cooling effect is too poor or caused by the ambient temperature is too high.
