Benefits of using a humidifier
Humidifier adds moisture to the air, which can benefit people with respiratory symptoms or dry skin.
There are several ways to use humidifiers in the home or office, but there are also some risks.
In this article, learn about the benefits of humidifiers, how to use them correctly, and precautions to take.
Types of humidifiers
While most humidifiers have the same basic function, to add moisture to the air, many types are available:
Steam vaporizers: These use electricity to create steam, which cools before it leaves the unit. However, there is a risk of burning the skin, and people should avoid using steam vaporizers around children.
Ultrasonic humidifier: Instead of electricity, these units use vibrations to vaporize water.
Evaporators: These produce humidity by blowing air past evaporating water.
Impeller humidifiers: These are generally child-friendly and use rotating disks, rather than heat, to vaporize water.
Central humidifiers: A person connects one of these units to the central air conditioning in the home or office to add moisture to the entire space.
Sizes can vary. Console humidifiers are large enough to add moisture to an entire house or office, while personal humidifiers are portable and easy to carry.
What is an Industrial Humidifier?
An industrial humidifier is a system that is capable of providing adequate humidity levels in a manufacturing environment. High-speed production processes add to the heat load in a building, bringing down the humidity. This can lead to a dangerous buildup of static electricity in a plant where dust and other flammable materials may be in the air. Processes such as woodworking, printing, and electronic and microchip fabrication, — which involve gluing, coating, and bonding — benefit from humidity control. Energy efficiency is also a consideration with an industrial humidifier.
What Does a Dehumidifier Do?
A dehumidifier is an appliance that takes moisture out of the air in your home.
If you or your family members have asthma or allergies, a dehumidifier might help relieve symptoms and make breathing easier.
This article will help you decide whether a dehumidifier is a worthwhile investment for your living space.
Application of Dehumidifiers for Various Industries
Excess humidity causes condensation and a broad range of hygiene problems in the product. Be it powdered food, spices, processed meat, snack foods confectionery products or breweries, consistent and controlled moisture conditions are necessary. Using dry air from a Desiccant dehumidifier can help in controlling the moisture content, which leads to perfect coating and longer shelf life of the food products.
The primary requirement for manufacturing of lithium batteries is a dry room with very low humidity. Lithium is extremely sensitive to moisture; thus, high moisture content leads to a reduction in performance and life of the product. Industrial dehumidifier ensures that the processing areas have the required amount of moisture in the air which is less than 14gms of moisture per kg of dry air.
The Leather is a hygroscopic material; excess moisture leads to the growth of mold and mildew on leather. Without proper humidity control, leather loses its shine, produces the foul smell, loses its strength and starts decomposing. Relative humidity above 40% leads to micro-organism growth that results in decomposition of leather. Dehumidifiers help in providing controlled moisture conditions during the processing of leather products.
Ultrasonic Mist Maker
I needed a simple mist maker/humidifier for a project that I was working on. I found lots of ideas on the internet, but they all lacked in one area or another, so I decided to design one. The following lays out my easy-to-build ultrasonic mist maker. It works fine and is, by far, the easiest ultrasonic mist maker/humidifier that I’ve ever had to get going.
Below is the circuit diagram of the final part of the project — the transducer driver. As shown in the circuit diagram, it’s a tricky oscillator design based on the ubiquitous tiny time chip NE555P (IC1) to generate proper drive pulse train for the atomizer transducer. In the circuit, the 5K multiturn trimpot (RP1) can be used to set the oscillator frequency to 113 kHz (±5 kHz) (TP1). Even though the ultrasonic mist maker device is configured to run on a single 5-Vdc to 12-Vdc input, this transducer driver needs a 20-Vdc to 26-Vdc (V_DRIVE) power supply channel in addition to a 5-V regulated DC supply rail. So a dedicated power supply circuitry will be introduced later to fulfill that crucial requirement.
