◆The humidity in the air is just as ubiquitous as the temperature. In some countries, the temperature is not high and the humidity is very high, which makes people feel stuffy and uncomfortable. At the same time, the damage caused by moisture and mold to metal oxidation occurs at any time without knowing it. When the relative humidity of the environment is greater than 60%, mold can grow, and the humidity greater than 85% is a high-incidence environment for mold.
◆In industrial products, optical lenses, magnetic recording materials (including CD-ROMs), video films, electronic information media, electronic components, instruments, meters, powder materials, paper, wood, silk, leather, tobacco, food, tea, grain, etc. Items that require humidity control.
◆Dehumidifiers are divided into chemical dehumidification and freezing dehumidification. This article refers specifically to freezing dehumidification. Refrigeration dehumidifiers use the principle of compressor refrigeration to dehumidify. The moisture in the air enters the evaporator to condense and frost, and then accumulates and drips out and drains into the drain. Dehumidifiers and air conditioners dehumidify differently. Air conditioner dehumidification is to reduce the temperature of the entire space and dehumidify, which is more suitable in summer and hot weather conditions. Dehumidifier dehumidification is to cool down the inside of the machine, discharge the water in the air, and increase the temperature of the space slightly, but the temperature difference is not reflected obviously, it is more suitable for four seasons, and the electricity consumption is also saved.
◆ The dehumidifier should not be used next to the heat source, and the air inlet and outlet should be kept unobstructed. Generally, the dehumidifier should be placed in the center of the space, and there should be enough space around it, and no items should be stacked. Keeping the air smooth can achieve a uniform dehumidification effect.
◆Freezing dehumidifiers will be frosted or frozen when used in low temperature (below 18 ℃) environmental conditions. Dehumidifiers with defrosting function will automatically frost, but dehumidifiers without defrosting function can use manual defrosting (power off. Way). Under normal circumstances, the temperature is low and the humidity is also low. If the humidity is lower than 40%, the effect of dehumidification may not be obvious and the speed may be slow. This is a normal phenomenon.
◆ The nominal dehumidification capacity is measured under standard ambient conditions. If the dehumidification capacity is 50 liters/day, it means the water outlet volume measured in 24 hours under the environment of 30℃/RH80%.
◆ During the operation of the commercial dehumidifier, the hot air discharged from the air outlet is a phenomenon of normal operation of the machine. In winter, the humidity is low and the temperature of the air outlet also drops significantly, which is a normal phenomenon.
◆ When consumers buy dehumidifier, the calculation of dehumidification capacity should comprehensively consider noise and other indicators. Generally, dehumidifiers with larger dehumidification capacity are more noisy and belong to the type of industrial equipment. Buy a few more small dehumidifiers.
