Jinjiale Spray Humidifier
1. Fine mist particles 2, high efficiency 3, high self-control accuracy 4, wide application range
Product details
Introduction and application scope of the humidification section of the new spray air conditioner:
The main features of the new spray section are:
1. Using a specially designed spray head, the mist particles are finer;
2. Using fillers to increase the contact area between steam and water results in higher efficiency;
3. Higher self-control accuracy and wider application range.
The spray room can heat, cool, dehumidify and humidify the air, filter dust, and absorb water containing gas (NH3'SO2) Among various processing functions, the seven major functions of the humidifier cannot be completely replaced by any type of humidifier, especially in harsh working conditions such as high temperature, dust, and fuzz. For example, in industries such as woolen textiles, cigarettes, chemicals, nuclear power equipment, cooling, etc., its disadvantages are that it occupies a large space, but its purification, cooling, low maintenance, and reliable operation characteristics are still irreplaceable in various humidification methods. Especially after improvement, the new spray air conditioner has a wider range of applications. Among them, the spray+wet film deformation combination method adopts a fine mist spray nozzle, which greatly reduces the occupied space area and greatly improves the cooling efficiency. In dry and hot climate conditions, the cooling can reach 10-15 ℃, and has great development and application prospects. In situations where high cleanliness and purity air quality are required, such as in the ultra clean integrated chip manufacturing industry, it is also used for the function of absorbing and filtering toxic and harmful gases, while reducing the cost of using activated carbon in the filtration section.
Jin JialeSpray humidifierWorking principle:
In the spray type, air and water molecules on the surface of the spray or wet film undergo frictional heat and moisture exchange to achieve humidification, cooling, absorption, dissolution, dust reduction, and water washing of the air. By changing the water temperature, dehumidification and humidification functions can be achieved.

The seven major functions of the spray section+the function of washing harmful gases with water:
The relationship between water temperature and air temperature and humidity determines various air treatment processes, as shown in the following figure:
T water=dew point T water=wet bulb T water=dry bulb
Isothermal cooling, isentropic humidification, isothermal humidification
1. Dust removal and water washing functions for harmful gases
During the direct contact between water and air, harmful soluble gases (NH3/SO2) in the air dissolve in the water, while reducing the dust content of the air and improving its cleanliness, meeting the air quality requirements of certain high-purity electronic chip manufacturing processes.
2. Cooling and heating functions
In summer, using groundwater or frozen water spray can achieve the purpose of air cooling and cooling, while using hot water spray can achieve the purpose of heating the air.
3. Spray humidification function
To meet certain process environment humidity requirements, ensure product qualification rate, eliminate static electricity and other process requirements, such as humidification of automotive spraying lines, cooling equipment for power plant equipment, etc.
Performance calculation parameters for spray room
Generally, the spray coefficient is used to represent the spray performance of the spray chamber, and other performance coefficients are used to represent the thermal performance of the spray type. The definition of the water vapor ratio U is the ratio of the amount of water sprayed to the amount of air, that is
U=W/GKG/KG, where:
W is the spray volume of the spray chamber, kg/h. The spray chamber usually uses a combination of U=W/G=1:1.5 spray and packing: U=W/G=1:0.5_1 is used

tw: Water temperature tl: dew point temperature ts: wet bulb temperature ta: dry bulb temperature
Calculation of absorption efficiency for harmful gases such as NH3 and SO2:
Water soluble absorption of harmful gases such as NH3 and SO2, absorption efficiency: u={inlet outlet (ppm) value}/inlet air (ppm) value
For example, the content of SO2 in the air is 45ppm, and after spray absorption, it is 8ppm. The absorption efficiency is: u=（45-8/45）=82%
In order to improve absorption efficiency and reduce costs in the water system section, it is recommended to use a combination of spraying and filling materials, which can save costs, especially for the renovation of air conditioning, and also have multiple effects of humidification and cooling (detailed design information can be contacted with Jinjiale).
Model designation:
For example, JPL-50000-A-EE is equipped with a built-in spray humidifier for a 50000 air volume air conditioner
Classification of sprinkler systems:
1. The sprinkler room has a bedroom, a vertical type, and a combination type sprinkler room with a middle filling layer.
2. Nozzle layout: single-stage (single row, double row), two-stage (three row, four row)
3. The spray+filler combination spray chamber is equipped with a filler spray box inside the spray chamber, which independently completes the humidification and water distribution method. It can fully contact with water for heat and moisture exchange, and can shorten the length of the spray section. This type of spray room has a better air purification effect and is suitable for air conditioning renovation.
