Information

The main considerations for selecting humidification methods are listed below:

1. Low setup cost.

2. Low operating costs.

3. Energy conservation.

4. Smaller equipment volume and higher humidification capacity.

5. Low maintenance costs.

6. Combine with existing resources, such as using existing boilers as power to replace electricity, or using existing pure water equipment to save general water treatment costs Etc.

7. No dripping or condensation.

The main reasons for choosing steam humidification for industrial applications are:

1. The steam humidification capacity is large, which can reach high relative humidity.

2. High absorption efficiency.

3. Completely sterilize.

4. Easy humidification control, isoenthalpy humidification, rapid reaction.

5. The appearance is simple, clean, and beautiful Etc.

Hospitals choose to use steam humidification, with the main consideration being the complete sterilization function of steam humidifiers.

If the steam volume is controlled by a control valve, the selection of the diameter of the control valve and the size of the CV value of its throat aperture are crucial.

The main reasons for choosing water mist humidification for industrial applications are:

1. The spray humidification is isoenthalpy humidification, which can greatly reduce the room temperature and save a lot of energy load of the chiller.

2. Easy installation and maintenance.

3. The setup cost is relatively low.

4. The humidifier machine has low power consumption.

5. Safety

Three state changes of water

Three state changes of water

Water is a ubiquitous substance on Earth that is colorless, odorless, and non-toxic. It undergoes three different states of change, including solid, liquid, and vapor, depending on temperature. In an ideal state, water freezes into a solid state at 0 ℃, with a smaller specific gravity. When we heat the ice, the temperature does not immediately rise and remains at 0 ℃. It needs to absorb a latent heat of dissolution of 80kcal/kg before it slowly turns into water at 0 ℃, forming a state of coexistence of solid and liquid phases. When liquid water completely turns into 0 ℃ saturated water, adding 1 kilocalorie (kcal) of heat will increase the temperature of 1 kilogram (kg) of water by 1 ℃. Continuing to heat will gradually increase the temperature of the water, and the continuous injection of enthalpy will increase the water temperature to 100 ℃. The temperature change process from 0 ℃ water to 100 ℃ water is called sensible heat (visible heat), which can be displayed on a thermometer. The specific heat of water is 1 kcal/kg, which requires 1 kcal of heat to increase the temperature of 1 kilogram of water by 1 ℃. At 1 atmospheric pressure, when the liquid water temperature reaches 100 ℃, the water begins to boil, known as the boiling point. Continue to provide heat, but the water temperature does not increase. Water gradually changes into gas and undergoes a phase change (from liquid to gas), which is the phenomenon of latent heat of water evaporation (which absorbs heat but cannot see temperature changes on the thermometer). The heat of latent heat of evaporation is very huge, at 539 kcal/kg, which is about 5.4 times the sensible heat (100 kcal/kg).
