Frequently Asked Questions:
Where Was The First Air Conditioner Invented And Why Was It Invented?
It's Just For A Project In School. Thanks!
Think about it! Air conditioning was invented because people wanted cooler homes during hot weather.
Copied From Wikipedia: The concept of air conditioning is to known to have been applied in Ancient Rome, where aqueduct water was circulated through the walls of certain houses to cool them. Similar techniques in medieval Persia involved the use of cisterns and wind towers to cool buildings during the hot season. Modern air conditioning emerged from advances in chemistry during the 19th century, and the first large-scale electrical air conditioning was invented and used in 1902 by Willis Haviland Carrier.
What Is The Ideal Temperature I Should Be Receiving From My Vents When It Is 100 Degrees Outside? 4 Ton Unit?
You need a pocket,probe, thermometer. While the AC is running place the thermometer in the vent where the AC is pulling in air to the coil. Leave it there for at least 5 minutes. This will give you the
air temperature of unconditioned air.
Now place the thermometer in an exhaust vent that is fully opened. This is conditioned air.
If unit is working within norms? The temperature should be about 15 degrees cooler coming out then what is going in.
Outside temperatures should have no bearing on the temperature of the conditioned air if the low pressure,suction, line is properly insulated.
What Size Air Condition Unit Do I Need For My 2100 Square Foot Home?
You cannot correctly size a central air conditining system bsed on square footage alone. Your house needs to be sized by an experienced HVAC person that understands how to perform a Heat/Cooling load analysis. It takes into consdieration the the following; perimeter of house in lineal feet, #stores, type of & thickness of insuation, type of windows and doors, direction the house faces, size of duct work, number of occupants.
Once completed it will give you the size of the ac unit in Tons.
If you oversize the a/c will not dehumidify the house and it will never cool adequately. If undersized the unit will run and run and burn out eventually.
Call a couple HVAC companies and ask if they can do the load calculations and price out the system.
Which Condition Is Best For The Formation Of Thunderstorms?
Which Is Low Level Cold Or Warm And Which Is Upper Level Cold Or Warm
well, i know in the world of meteorology it has to do with atmospheric conditions. heat rises and cold sinks, this is what causes storms. the sun heats water and it evaporates, when it gets high enough into the atmosphere it starts to cool and condense forming clouds. when the cloud gets too heavy you get rain, in the case of storms you have 2 masses of air 1 being cold and dry, and 1 being warm and moist. when these 2 air masses collide it creates thunderstorms. this is typical in the central plains region of the united states. so i'd think its on the same concept only on a massively smaller scale
What To Address 1St Poor Insolation Or Old Underpowered Air Conditioning System In A 1950 La - Valley Home?
The House Was Built In 1950, With Practically No Insulation.
I'Ve Had Insulation Put In The Attic.
However, There Is One Large Part Of The Living Room That Was Expanded Many Yrs Ago, By Previous Owners.
Its Basically A Thin Flat Roof, No Insultation No Attic In That Area.
In Hot Summer Days The Heat That It Transfers Into The House Is Amazing, The Living Room Gets Incredibly Hot.
The A/C System Is 19 Yrs Old About 3 Ton, Where 3.5-4 Is Recommended By The Size Of The House.
I Would Love To Do Both, But Budget Is Limited.
What Should Make A Bigger Impact For The Money.
Spending $X To Get An Additional Roof Layer With Attic Space And Best Insulation?
Or Replacing The A/C And Ducting To A 4 Ton New, High Efficiency Unit?
Assuming the added living room is conditioned from your existing unit, i would blow-in insulation between the ceiling joists. This will give you added insulation which for now will cut down on the heat gain from the roof. It only takes a few holes in the ceiling to make this happen and it can be repaired easily. If the room is still too hot using the existing HVAC system, add a ductless unit in the living room till you get the money to change out the existing HVAC system.
Before you go calling in someone to do a Manual J calculation, insulate as much as you can. The biggest source of heat in any space is from the roof and windows. Consider new windows and use the tax credits available to offset the price. The age of your house indicates it is probably got a lot of sources of infiltration which will also drive up the costs of cooling. Find the leaks and fix them.
Later, replace your existing system to a high efficiency unit or geothermal system for the tax credits again.
