HUMIDITY is, unfortunately, one of the least understood, most important aspects of comfort conditioning. It’s understandable that it is misunderstood. Humidity is intangible. You can’t see it, you can’t touch it, and it has no color, odor or sound.
Still, it’s so important for so many reasons, such as comfort, health and preservation. Humidity is as important as heart for these benefits. What’s more, it is needed for a greater portion of the year in some areas. Still maintaining and controlling proper humidity levels are not being satisfied. But they can be, and will be, if we understand humidification and the application in which it is being used.
HUMIDITY is the water vapor within a given space. RELATIVE HUMIDITY simply is the amount of moisture in a cubic foot of air at a certain temperature. The warmer the air, the more moisture it can hold.
If your home is heated to 70°, the air is capable of holding 8 grains of water. That’s 100% relative humidity, which is the maximum amount of moisture that 70° air can hold.
We now know that 70° air is capable of holding a lot of moisture. The problem is how to get the proper amount of moisture in the air.
EVAPORATION is to change states from a liquid to a vapor. If you boil water on the stove you will find that HEAT is needed to change water into vapor. If more heat is added to the water, the water will evaporate faster. So the rate or amount of evaporation is determined by the amount of heat applied to it. Unfortunately, your furnace can’t provide that kind of heat.
YOUR FURNACE is designed to deliver a certain temperature of heat, which is about 125° discharge air. If you have a high efficient heating unit your discharge may be as low as 95°. At these low temperatures it’s very hard to evaporate the amount of water needed to satisfy humidity comfort levels.
EVAPORATIVE HUMIDIFIERS work by heated air from the furnace passing through a pad. Water heated to about 70° flows over the pad. Heated air going through the pad is supposed to evaporate the water and enter the air stream. These systems are limited to the output of humidity for few good reasons.
It’s hard to evaporate 70° water with limited amounts of heat. This means water going through the system is not evaporating but going down the drain. Some units can deliver over 150 gallons of water a day, and if you’re supplying hot water to your humidifier, it can drain the hot water tank 3 times a day.
Since this type of humidifier relies on heat from your furnace, it will work only when your heat is running. If your house is warm and well-insulated, your furnace does not run for long periods at a time, which means your humidifier is not running either. Without running, your humidifier cannot satisfy your humidification needs.
Some manufacturers recommend placing your thermostat fan switch in the on position which will lock the fan in high speed and allow the humidifier to run non-stop. If you run your fan constantly to increase the efficiency of your humidifier, this provides inadequate humidification.
Running the fan constantly will also waste a great amount of water and will increase your water bills. More importantly, your furnace was designed to run in low speed during the heating cycle. When your fan is in high speed during the heating cycle, the start up and efficiency of the furnace is lowered.
So, with all this wasted water, gas and electricity, we still can’t satisfy humidity levels — until now, through the process of ABSORPTION.
THE HUMID-A-MIST SOLID STATE PULSE HUMIDIFIER is designed to work by the process of absorption.
ABSORPTION is the process where a substance takes in matter, which is distributed through out the substance’s volume. This means dry air takes in moisture and then distributes it through its volume.
The average heated home during the heating season maintains 10-15% relative humidity. To satisfy health and comfort levels we need to maintain 35-50% at 70°. To achieve and maintain these goals the HUMID-A-MIST PULSE HUMIDIFIER was designed to solve the problem of adding moisture to the air.
Every heated home has the problem of dry air: if you’re heating, then you’re creating dry air. Dry air, however, has no choice but to accept moisture. When it is added at a controlled rate, the end result is air with proper humidity levels.
THE HUMID-A-MIST HUM-100 is a solid state humidifying package that will operate with any forced air system and will not interfere with the normal start up or efficiency of your furnace. The system is designed to pulse a fine mist of moisture to enter the air stream at adjustable time intervals to accommodate a wide range of dwellings. When moisture is added at a controlled pulse rate, dry air is capable of absorbing and distributing it evenly throughout your home.
Our NOZZLE is a small orifice that has a small stainless steel ball bearing installed directly in the flow of the water. When water is passed through, the ball bearing is designed to spin. This causes the water to break down into a fine cloud of moisture that will allow dry air to absorb moisture more easily. Our nozzle, working together with our pulse board, can deliver a range of 1.4 to 14.4 gallons of water per day depending on which pulse setting you select. We recommend setting it at 1-3 seconds for a 1200 square foot area, 3-5 seconds for 1200-2500 square feet, and higher for commercial spaces. If you follow these settings, the maximum amount of water that will be used is about 7 gallons per day.
Because we FILTER all our water, none of it is wasted. We use 100% of all water that passes through our system. Our filter is a 5 micron filter designed to help eliminate scale and mineral deposits. Because we have no standing water like most systems, no bacterial growth can enter your air stream.
Because our system is ELECTRONIC, it can humidify any time you need humidity, even if your heat is off. The system operates on the principle of absorption, and air at 70° can hold a lot of moisture; therefore, the heating unit does not have to run. This means when you set the humidistat at your desired setting, our system will operate to satisfy your needs. We feel that when you set your thermostat to 70°, you expect it to reach 70° — the same applies to relative humidity, and that’s what we produce.
THE HUMID-A-MIST PULSE HUMIDIFIER is the first pulse humidifier offered to the home owner that produces maximum control and maximum efficiency.
