Air duct wet film humidifier

1. principle
   Clean water is sent to the inlet hole at the top of the air duct humidifier through a water supply pipeline or a circulating water supply system. Under the action of gravity, the water permeates and diffuses along the surface of the wet film, and after heat and moisture exchange with the flowing air inside the air duct, it achieves the purpose of evaporating, vaporizing, and humidifying the air.

2. overview
   Fan coil unit is the terminal equipment of central air conditioning, mainly composed of fans, cold and hot coils, water receiving trays, and controllers. Due to its advantages of convenient use, low cost, and reliable operation, it is used in households, apartments, hotels, guesthouses, office buildings, and more. Traditional fan coils only have a temperature regulating function, but with the improvement of living standards, people have put forward higher requirements for air conditioning, hoping that fan coils can increase the relative humidity of the environment while heating.
   The specialized wet film humidifier for fan coil units is installed at the downstream end of the hot and cold coils in the fan coil unit, adjacent to the coil unit. The humidifier can be manually controlled or automatically controlled for relative humidity through an external dedicated humidity controller.

3. Characteristics of fan coil humidifier

1. Low water consumption, unique water-saving drip device

2. Low wind resistance, does not affect the normal air supply of the fan coil unit

3. Low power consumption, not exceeding 10W

4. Easy to use, reliable to operate, and capable of automatic humidity control

5. Affordable price, suitable for large-scale adoption

The frame of the air duct wet film humidifier is made of special rail shaped structural steel, which has undergone spray coating treatment and has high strength, corrosion resistance, good sealing, and beautiful appearance. The air duct wet film humidifier has two forms: frame structure and welded structure. When the interface length of the air duct is greater than 1200mm, it is recommended to use frame structure.

The built-in water tray and drain port of the air duct humidifier ensure that excess water from the humidifier can be discharged smoothly.

2. Installation of fan coil humidifier

1. Directly installed inside the air outlet of the fan coil unit and fixed on the hot and cold coils.

2. Inlet: DN15 standard internal thread interface, connected to clean tap water.

3. Drainage: As the fan tube humidifier is installed inside the fan tube, its drainage flows to the fan coil water receiving tray and is discharged through the fan coil's drainage pipeline.

1. The usage conditions of wet film humidifier:

Sectional wind speed: ≤ 2.8m/s,>2.8m/s

Water quality: tap water or equivalent water quality

1. Water supply temperature: 3-45 ℃
   Water supply pressure: 0.05-0.4Mpa

2. Inlet air temperature: 5-60 ℃

summarize

1. Wet film humidifier is a device that uses isentropic humidification to drive air, consuming only the power consumption of the fan and circulating water pump. It has the advantages of simple structure and energy saving.

2. This article starts from the humidification mechanism of wet film humidifiers, studies the humidification performance of wet film humidifiers, and analyzes the parameters that affect the humidification performance of wet film humidifiers, including water temperature, air dry wet bulb temperature, and air flow rate.

3. Wet film humidifier is a clean and energy-saving new type of humidification equipment, so it can be widely used in the field of air conditioning. In short, in today's increasingly prominent energy and environmental issues, wet film humidifiers are increasingly favored by people for their advantages of energy saving, pollution-free, no white powder, and clean humidification, and are a promising technology for development.
