Physical characteristics

Isothermal humidification

Isoenthalpy humidification

Temperature changes

The dry bulb temperature slightly increases during humidification

The dry bulb temperature decreases with the isoenthalpy line during humidification

3

Absorption distance

Short

Depending on the distributor structure, it can reach up to 60 centimeters

No need to install a water baffle

Long

The shortest distance can reach around 1.5 meters

Need to install a water baffle

Wet film humidifiers do not require water baffles

4

Humidification efficiency

Very high; More than 95%

Low; According to different humidification methods, the humidification efficiency ranges from 30% to 75%

5

Humidification quality

Okay; High-temperature sterilization

Poor; Susceptible bacteria

6

Other auxiliary energy sources

Electrode type and electric heating type are not required

Boilers and heat exchangers require boiler steam

Most water mist humidification is not required

The second fluid requires compressed air

7

Preheating air temperature

No need to preheat air to a higher temperature

Preheat the air to a higher temperature

The higher the demand for relative humidity, the higher the temperature

8

Power consumption

The machine itself consumes a lot of electricity

The power consumption of 1 kg/h humidification is 750W

The machine itself consumes very little electricity

9

Single humidification capacity

Small& Nbsp

Can be connected in parallel

Very large

Can be connected in parallel

10

Humidification output control

Most steam humidification can be proportional output controlled

The electric heating type adopts SCR to achieve linear proportional output

Most water mist humidification is controlled by on off or several sets of on off segments

Two fluids can achieve proportional output control

11

Control accuracy

Most steam humidification control accuracy can reach± 3-5

Electric heating adopts SCR up to± 1

Most water mist humidification control accuracy is within± 5-10

12

Water quality requirements for use

The electrode type can use municipal tap water

Other steam humidification requires pure water, otherwise the maintenance workload is significant

Two fluids, water washing, and wet film can use tap water

Other water mist humidification requires pure water, otherwise the maintenance workload is significant
