1. The water cycle is normal for more than a year, but now the cooling rate seems to be slower and slower, the more obvious it is when the temperature is higher?
Answer: Water recycling is very simple, but regular maintenance work cannot be ignored. There are many seemingly faulty problems that are caused by failure to do regular maintenance. The electrical power of the water cycle and the heat taken by the refrigerant from the load need to be removed from the radiator at the front vent hood. If the front vent hood is full of dust and willow cotton, etc. will hinder the dissipation of these heats, and the cooling effect will be Great discount. Generally speaking, the decrease in cooling capacity under normal use conditions is caused by poor ventilation and heat dissipation or high ambient temperature.
2. The water circulation of the low temperature thermostat was normal before, but now it is found that the noise is much louder than before, what is the reason?
Answer: I mentioned the routine maintenance of the water cycle before, and this issue is also related to it. Everyone knows that there are very few impurities in the water. Even if distilled water is added to the water tank, it is impossible to guarantee that there is no impurity at all. For the water cycle, the general temperature is set at 20 ℃, especially adapted to the growth and reproduction of microorganisms. After a long time, these microorganisms will block the filter of the waterway and cause the backwater to be poor, and the pump will have a loud noise. Sometimes these microorganisms are attached to the surface of the heat exchanger, causing the heat transfer effect of the heat exchanger to deteriorate and the cooling capacity to become smaller. Therefore, the daily maintenance work must be done in strict accordance with the requirements in the manual, the inner tank should be cleaned regularly, and the tank should be kept dry for a long time. There seems to be water leakage in the water circulation, and sometimes there will be a few drops on the ground. Is there a leak on the waterway? Generally speaking, during normal use, there will be no leakage on the waterway. When the relative humidity in the air is relatively high and the relative humidity in the air is too large, dew condensation is easy to condense at the water pump, water pipe joints, and external water pipes in the water circulation circuit. After accumulating, it will drip onto the ground. Leaking place. If you care about this, turning on the air conditioner to lower the room temperature or dehumidifying can avoid dew.
