What else can I help you with?
Why are air condition units often positioned close to the ceiling in hot countries and heaters close to the ground in cold countries?
Cold air falls and hot air rises. That simple. Think of hot air balloons.
Truck engine temp goes from hot to cold?
it should start at cold
What insulation should you use for a cold water pipe?
poly venal chloride
Why should we insulate houses?
Well like wearing a heavier coat during cold spells, insulating your home gives you and your home protection from cold.
What hardness should SAE 1010 cold rolled steel be?
According to the ASME, SAE1010 {ASTM A179, ASME SA179} cold rolled steel (cold drawn) should have a Rockwell hardness of 60 RB. Hot rolled it is reduced to 55 RB. *(Brinell hardness, 105; Knoop hardness, 123; or Vickers hardness, 108)
Where should vents be placed-celiling or floor for AC?
Ceiling. Cold air fails
In winter where should the heater be placed in the room near the floor or near the ceiling?
Heat naturally moves to colder air. Place the heater on the floor and it will rise to the ceiling, as it is lighter than the cold air.
Why are cold air returns typically located near the ceiling in a room?
Cold air returns are typically located near the ceiling in a room because cold air is denser and heavier than warm air. Placing the returns near the ceiling allows the colder air to be efficiently drawn back into the heating system for re-circulation, helping to maintain a comfortable temperature in the room.
What positions should high low air returns be in summer and winter?
Only the low air returns have dampers, and they should be open in winter, so they can suck in the lower cold air (cold air sinks), and in summer the dampers should be closed, so the high air returns suck the hot air near the ceiling (hot air raises)
Why are heaters fitted near the floor and air conditioners near the ceiling of a room?
Cold air falls...warm air rises
Why are radiators placed near the floor and not the ceiling?
They are placed on the floor because heat rises. If the heater was up high, the ceiling would be nice and warm, while the walls and floor would be cold.They are placed on the floor because heat rises. If the heater was up high, the ceiling would be nice and warm, while the walls and floor would be cold.
Why is the air in a heated room usually cooler near the floor than the ceiling?
because hot air rises and cold air sinks.
Why is it hotter near the ceiling than near the floor of a room?
Hot air rises because it is less dense than cold air, leading to a concentration of warmer air near the ceiling. This phenomenon is known as convection. Heat energy also tends to accumulate near the ceiling due to factors like poor insulation and the heat distribution from various sources within the room.
Which way do the ceiling fan blades go in the winter?
The direction that would cause the air movement to circulate up toward the ceiling instead of down. Usually counterclockwise looking from the floor up. That way the heat hanging on the ceiling will be recirculated down the living area without causing an uncomfortable cold breeze.
A student put his foot on a cold floor and immediately pulled his foot of the floor what type of response is this?
The floor is cold?
Your forced air vents heat are in the ceiling cold air returns are baseboard what to do to make the heating more efficient?
First,I would check the houses infiltration rate and try to improve it. Second I would look at the fuel efficiency rating of the equipment and improve things there if it is an older unit. Vent placement in your case is trivial, returns belong down low where the cold air is.
In order to heat a room evenly should heating vents be palced near the floor or near the cieling of the room?
Heat rises. So, in areas with long winters, the vents typically are in the floor. But it depends on the construction of the house, where the heating unit is installed and what type it is, etc. So, no easy answer. Ceiling fans are helpful in keeping air circulating, moving warmer air from the top of the room downward which helps even out the temps from floor to ceiling.
