Depends on the outdoor temp. If it's 75 outside, your system should easily bring your house down to the 68 degree setpoint. If it's 100 degrees outside, you'll never get there. Unless, that is, your system is too big for your home. Then it will cool you down just fine, but you'll have humidity problems...that's a whole other discussion. Most central air conditioning units are designed to maintain a 75 degree indoor temp at 55% relative humidity on a 95 degree day. So a indoor/outdoor temperature difference of about 20 degrees or so is what you should expect.
Most people are comfortable with the humidity at 55% indoors. During periods of extreme dryness outdoors, though, a sharp drop in humidity may necessitate the use of a vaporizer indoors to add some moisture to the air.
50-60% is usually a good rule of thumb.
A vapor barrier is an impenetrable layer that keeps water from seeping through from the ground. It is always advisable to use a vapor barrier regardless of humidity.
Depends. Mine only goes down to %60. From what I've read a good humidity level is the 40-50s range and to buy or rent a Hygrometer to accurately measure the space
You should get a Indoor Thermometer & Humidity Gauge. If your house humidity for any room is around 38-45% your great. Above 48% get a humidifier. But for the most part it drops in the winter and gets higher in the summer.
The best way of using a humidifier is to keep it clean and measure the humidity levels. If both of these acts are not done, a humidifier can actually make you sick. Make sure that you change the water regularly and clean the water tank regularly making sure to rinse after you clean it. It`s also important to change the filter. You can also check the level of humidity in the room using a hydrometer. They should be between 30-50%. If you have asthma or allergies you should consult a doctor before use.
A research by ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers) shows that the ideal indoor humidity level for health is about 40%-60%.You can use a hygrometer to measure the indoor humidity. You can use a humidifier to adjust the humidity of your room. There are different sizes of humidifiers and they each have a different humidifier rating, as well as square footage usually covered. Cool mist/evaporative humidifiers are generally cheaper than warm mist and ultrasonic ones. Good brands such as Dyson, Keecoon【large-scale capacity】, Panasonic, etc.
No, 100% no, if anything increase humidity slightly
It should be hooked to a cold line.
Not necessarily. Just maintain the correct temperature range for the species - and maybe increase the humidity a little.
it should be down in order to avoid overhydration
that depends on the temperature outside the greenhouse and the size of the greenhouse ect..
It would depend on the air temperature inside the classroom. There are differences in data, but generally, experts with Energy Star and the Consumer Products Safety Commission agree that 40 percent is considered to be an acceptable relative humidity point. The CPSC says this is the minimum (and below that a humidifier should be used) while this is in the middle of what Energy Star recommends (between 30 and 50 percent). Regardless, a room should never be above 60 percent as mold and bacteria grow easier above 60 percent relative humidity.
No, you should not use a humidifier in a main trunk line that is made out of duct board. This will cause the duct board to rot from the moist.
Yes..... most definitely. I even once had a sinus infection and a friend of mine came and brought me a humidifier... and by the next day I was all cleared up.
I am a Registered Piano Technician, so I feel pretty well qualified to answer this question. Humidity control is crucial for keeping your piano in tune and preventing humidity-related problems that appear over time, like soundboard & bridge cracks, loose tuning pins, sticky or rattling keys, sluggish action parts, etc. It's best to keep your piano at around 42% relative humidity year-round. Consistency is the most important thing, though. You can put a room humidifier by the piano, but there are several drawbacks to that approach. First, you would have to monitor the humidity level in the room 24/7 to be sure that it's staying consistent. If the room housing the piano is large, or if it's open to other parts of the house (i.e., no door or a door that stays open a lot), you are trying to humidify a very large area, which most room humidifiers won't be able to do. Room humidifiers are noisy (you're trying to listen to and enjoy music, right?) and you have to fill them usually once every day or two. Finally, using a room humidifier will not do anything to bring the humidity level in the room DOWN when it gets too high (like during a rainstorm). There is a very effective humidity control system called a Piano Lifesaver System, made by a company called Dampp Chaser. It must be installed by a piano technician. It has both a humidifier and a dehumidifier with a humidistat, so it's constantly monitoring the humidity level under the soundboard and turning on whichever end of the system is needed. It is almost completely invisible - it mounts up underneath the soundboard in the piano. There is a little LED light panel mounted under the keyboard that will flash when the humidifier needs water (typically about once every week-10 days in dry weather, sometimes as little as once a month in humid conditions). It comes with a watering can that fits onto a fill tube on the piano; when the light flashes, you put water in the can, attach the can to the fill tube and dump it in. It's best to use distilled water to extend the life of the humidifier and humidifier pads, along with a pad treatment solution that you can buy from your technician. It's not as cheap initially as a room humidifier, but there is a study out there that shows that the monthly cost of running & maintaining the system turns out to be much cheaper than a room humidifier. And, you're protecting a big investment in your piano. I know this sounds like a commercial for the Piano Lifesaver, but I truly believe these systems work well and are definitely worth the money.
