Humidity in the air is as ubiquitous as temperature. The temperature of yellow plum season in the south is not high and humidity is very high. People feel sultry and uncomfortable. At the same time, damp and mildew damage to metal oxidation occurs unconsciously at any time. Moulds can grow when the relative humidity of the environment is more than 60%, and those with humidity greater than 85% are the high-incidence environments.

 

Optical lenses, magnetic recording materials (including compact discs), image films, electronic information media, electronic devices, instruments, meters, powder materials, paper, wood, silk, leather tobacco, food, tea, grain and so on are all items that need to control humidity.

 

Dehumidifier differentiation chemical dehumidification and freezing dehumidification, this paper specifically refers to freezing dehumidification. The refrigeration dehumidifier uses the principle of compressor refrigeration to dehumidify. The moisture in the air enters the evaporator and frosts the condensation, then accumulates and drips out, and discharges into the sewer. Dehumidifier and air conditioner have different dehumidification methods. Air conditioner dehumidification is to make the whole space temperature drop dehumidification, in summer, hot weather conditions are more suitable. Dehumidifier dehumidifier is the internal cooling of the machine, the water in the air is discharged, the temperature of the space is slightly increased, but the temperature difference is not obvious, more suitable for four seasons, electricity consumption is also saved.

 

The dehumidifier should avoid being put beside the heat source, keep the air inlet and outlet unobstructed. Generally, the dehumidifier should be placed in the middle of the space, and there should be enough space around it, and do not pile up articles. Keeping the air flowing smoothly can achieve even dehumidification effect.

 

Freezing dehumidifier will frost or freeze when it is used in low temperature (below 18 C). The dehumidifier with defrosting function can automatically frost, but the dehumidifier without defrosting function can use artificial defrosting (power-off mode). Generally, the temperature is low, the humidity is low, the humidity is below 40%, the dehumidification effect may not be obvious, and the speed is slow, which are normal phenomena.

 

Nominal dehumidification is measured under standard environmental conditions. If the dehumidification scale is 50 liters per day, it means the 24-hour measured effluent volume at 30 C/RH 80%.

 

During the operation of the dehumidifier, the hot air discharged from the outlet is the normal operation of the dehumidifier. In winter, the humidity of the outlet is low and the temperature of the outlet is obviously decreased, which is a normal phenomenon.

 

When purchasing dehumidifiers, consumers should take noise into account in the calculation of dehumidification capacity. Generally, dehumidifiers with larger dehumidification capacity have higher noise and belong to the type of industrial equipment. If they need low noise and dehumidification to meet the requirements, it is suggested to buy more small dehumidifiers.
