Dehumidifier aims on dehumidification

The dehumidifier uses refrigeration and heating methods to remove moisture from the air to reduce the relative humidity of the air. After the air is absorbed into the machine, it is purified by a filter and then cooled and dehumidified by an evaporator, condensing excess moisture into liquid water and lowering the RH level. Due to the dehumidified condensate taking away part of the heat and humidity, the temperature will be reduced. To get a suitable temperature and humidity level, the dehumidifier makes the dehumidified air heated by the condenser, increasing the temperature, which reversely improves the effect of the dehumidifier. The difference between a dehumidifier and an air conditioner is their functions. An air conditioner removes the sensible heat in the air and minimizes the loss of damp heat. Because the excessive loss of moisture will make people feel too dry, which is not conducive to the physical health of the human body. Differently, a dehumidifier reduces the heat and humidity level of the environment, which is more suitable for goods storage and other special requirements. The dehumidification capacity of the general air conditioner is about 30% of the professional dehumidifier.

Influence of air humidity on human comfort and health

1. Humidity and comfort

According to skin sensation, physiological response and thermal effects, the "standard effective temperature index" is obtained, which shows that the relative humidity is in the range of 20% to 50% and the dry bulb temperature is in the range of 23 - 25 °C. This will be the most comfortable environment for human body.

2. Humidity and health

Unsuitable humidity can easily make people sick and affect human health. Many pathogenic bacteria survive easily in over-dried or humid environments, and live longer in high-humidity environments. Studies have shown that when the relative humidity is 35% to 50%, the survival time of bacteria is reduced, and skin diseases caused by dryness are also relatively reduced.

To live in a comfortable environment, it is suggested to use a dehumidifier at home. Preair is a professional commercial dehumidifier manufacturer that can provide various restoration dehumidifiers for sale


There are huge demand for dehumidifier around people's daily life.
