During summers the relative humidity in our poultry house reaches up to 95 % . The temperature also goes upto 32 *. The outside temperature varies between 42 to 48* celsius, while relative humidity 95 To 97 %.We have a closed poultry house with pad cooling system & automatized systems for  feeding, watering,egg collection & manure removal.During this period ( June - August)the birds are under severe stress with lowered egg production. Any suggestions for reducing the humidity ?

You have a couple of options.\n\n1. Install insulation in the ceiling and walls.  Be sure to prevent the insulating material from contaminating the chickens.  This won't really reduce the humidity, but it should keep the house from warming up as fast in the morning.\n\n2. Replace the pad coolers with air conditioners.  Would need insulated walls and ceiling to prevent this from becoming hugely expensive.\n\n3. Put the poultry house underground.  Make sure it is properly ventilated to prevent build up of radon.

Our body can't take much of anything. Too much of anything spells disaster. Same applies for the surroundings we live in. Not just the temperature but also the bacterias in our workplace or home have an effect on our health. Surveys tell that children who live in farms or away from city pollution are healthy not because their living place is pollution free but because they are open to all kind of germs which makes their body more immune to germs. Same way if you get used to a constant temperature its bad effects will be seen when you are in a situation where the temperature cannot be maintained. So Constant changes in room temperature should not be too bad... but see that its not on extremes. Keep it warm or cool if you can control it.

Most of the water molecules in the air in your freezer have sublimated to a solid state inside. Therefore, there are less water molecules in the air making it less 'humid'.

I have the same problem - No one has mentioned "environment" (that I saw?) - It's now Spring - What kind of climate do you live in? I'm in CO - and the Humidity today was 8% (Yes, EIGHT percent) - but "cold" so the heater was blasting all night ... so dry air effects me as well as lack of moisture that comes with higher humidity...\n\nOption #2) - Do you take Tylenol PM (or any antihistamines?) - For whatever reasons - these too dry out my eyes (well, B/C they're a type of antihistamine)\n\nOption #3) - People have already mentioned allergies... and alcohol - May wanna check with an allergist about down pillows, or Spring hay fever - or even "mold" if you are in a northern climate, and the windows are sealed - I found my "allergies" were worse in the winter than summer, and never understood this since all plants/trees/weeds and such are "dead" (dormant) - well, turns out Mold in the air ducts was the cause... \n\nIf you go to a Doc, and tell him about using "Clear Eyes" or "Visine" - those too have a "rebound effect" and he'll (she'll) encourage you to go to "natural tears" for the others' can CAUSE red eyes after long term use... But I too still use them, cuz "natural tears" don't remove the red - and don't wanna look hung over at work - When I'm NOT! LOL \n\nCheers and good luck!

A desert cooler takes advantage of very low relative humidity to acheive its cooling properties.   Rather than relying upon a refrigerant system (i.e. Freon) with a compressor to circulate the refrigerant, a desert cooler uses evaporation of water to remove heat.  With a low relative humidity, water can evaporate quite rapidly, taking a lot of heat energy along with it.  \n\nThere are a variety of different techniques to exchange and remove heat from the air.  One that is used in less arid climates is called a swamp cooler, in which water is pumped from a pond, through a heat exchanger and then back through a fountain in the pond.  The fountain aids in the evaporative process, helping to keep water cooler.  \n\nWhile a desert cooling system may not be able to develop as cold of temperatures as a refrigerant-based system, it still can effectively reduce the air temperature, and do so using less electricity since a compressor is not required to run.

Humidity is directly proportional to heat. Humidity is relative to the temperature.  The warmer the air the more moisture it can hold.  If the humidity is 100% and the temp is 50 f, then the air is saturated and cannot hold anymore moisture.  But is the temperature in the same situation would rise while the moisture remains the same, the % of humidity will lower.

How about a small fan with a bowl of water in front of it to increase air humidity.  It may be worth trying...;

An air conditioner usually brings in some air from the outside. Even if it doesn't, no room in your house is anywhere near airtight-- for example, your door has a gap in the bottom of at least 1/4 to 1/2 inch.

Mist cooling is simply introducing an atomized spray of water into an airstream to cool the air.   As the water droplets vaporize and dissolve in the air, they remove heat energy from the air, leaving the air slightly cooler.\n\nThese systems are most effective in dry heat climates, where the relative humidity is low.  The water can evaporate much more quickly, removing more heat.\n\nThe lowest temperature that can be conceivably reached (provided that the system were 100% efficient) is the dewpoint temperature, also known as the wet-bulb temperature.  If the air were cooled to this temperature, its relative humidity would be 100% and it would be at maximum moisture saturation.  So, in most cases, these coolers can only reduce temperatures to 60 or 70 degrees under normal conditions, unless you're in a desert or other arid region.\n\nMost mist coolers are smaller, portable systems that use a common fan with several nozzles in front of it that produce a very fine mist spray of water.\n\nSmaller systems are also available for cooling milling work in tooling manufacturing.  These systems typically have an additive in the water supply to reduce the oxidation effects of the water.

I'm guessing that you live in the Bradenton area, judging from your previous question. I live in the Ft. Lauderdale area. Right now is our late spring and now going into early summer. The humidity will get higher in May and the temperature will hang around 90 everyday, and that'll bring on the rainy season starting between late May and late June. It's just plain 'ol hot, humid, with lots of rain and sunshine all mixed together between June and October. If you're outside, you'll pray for a little seabreeze, which won't help much, but anything is better than 92-95 degrees, 70% humidity, and little wind. Bradenton has lots of afternoon thunderstorms in the summer (due to the seabreeze), so that'll cool things down in the evening. Oh, and welcome to hurricane alley.

It depends on the relative humidity. The location with more relative humidity will cause more "sweating" or condensation on the outside of the glass. \n\nThis will usually be indoors, since it is usually drier indoors, thanks to air conditioners in the summer, and heaters in the winter.

You should choose something you could actually finish, so keep it simple.  One project that you could finish and possibly sell copies to friends and family: a digital thermometer and relative humidity sensor.  Everyone wants to know the temperature.  The problem with the relative humidity sensor is that the sensor is not linear from 0-100%RH, so there is error.  Using a PIC microcontroller you can write a software correction program that will correct the sensor output (the thermometer can have the same problem).  Depending on how much math background you may have, this could be an easy or difficult project.  The upside is that you may be able to commercialize the product.  We've done projects with silicon pressure diaphragms correcting for pressure and temperature error (requires a matrix solution leading to polynomial coefficients and a lookup table) - it took years however, so keep the project simple.

It's the actual temperature with humidity, wind chill factor (if applicable), dew point and other conditions taken into consideration. There's actually a mathematical equation to figure it out but it may be hard to find since the calculations are done by computers these days.

I would appeal to the landlord if he could do it before hand. \n\nSummer tecnically doesn't start until the 21st.  So he hasn't done anything wrong. \n\nHere in canada, the rental landlords turn the air on June 1st, so there have been a few really hot & humid days, that I have had air on, & felt sorry for those renters unable to use it. \n\nUse swimming pools or your tub to cool them down, dress lightly, and buy some fans for the rooms until it is installed. \n\ngood luck to you.

Yes.\n\nThe body cools itself by evaporation of perspiration from the skin.  In dry air, perspiration evaporates rapidly causing a cooling affect but in humid air, perspiration evaporates less quickly so you don't feel as cool.  You'll feel warmer at the same temperature in a humid climate.\nhttp://en.wikipedia.org/wiki/Humidity#Effects_on_human_body\n\nIn it's simplest form, the "heat index" attempts to capture this property of perceived temperature by factoring humidity and temperature into a single value.\nhttp://en.wikipedia.org/wiki/Heat_index\n\n\nSome of the weather services such as Accuweather have devised ways of expressing the perceived temperature that include multiple factors including: "ambient temperature, wind speed, solar intensity, humidity, precipitation intentisty/type, elevation, and atmospheric pressure".  The purpose of this is to try and include all factors that might affect how we perceive temperature.\nhttp://www.accuweather.com/iwxpage/adc/help/pr_realfeel_pr.htm\nhttp://wwwa.accuweather.com/company.asp?page=about\n\nWeather.com has their "Feels Like" temperature rating which is similar.\n\n\nOf course, there are situations where it is so hot that it doesn't matter about the humidity.
