The isolation and size of air conditioner
Preformed Concrete HomesThe isolation and size of air conditioner
An HVAC contractor can determine the size of the air conditioner to install in your home, but the size of the unit as the best unit for your home? There are many variables to consider when you have a new unit installed in your home. These variables are grouped into a load calculation is performed by the contractor or mechanical engineer. How do they do well? What can an engineer means a bigger house with a smaller unit than it is in another house with lesssquare meters, in some cases?
We will use the three little pigs as an example (with some artistic license). The first little pig lives in a house made of metal found on a platform of four inches of soil. The second pig lives in a small wooden house that sits on a slab of concrete has been poured into the ground. Finally, the third little pig lived in a house built with blocks of 10 cm thick Mason, also sitting on a slab. None of the houses are insulated. All these houses have the sameinternal dimensions, but are responsible for different calculations, which means that everyone can have a different size air conditioning units.
A load calculation is a mathematical function developed to determine the amount of heat that must be moved to cool or heat a home. The main reason for differences in the calculation of the load is called R-value of each home. R-value is a measure of thermal resistance ("R" word comes from the resistance) of asubstance or object. Although you may not be able to determine the R value of your home, you can easily understand the concept of looking at every house in pigs. "
The metal construction of the first pig lives in the soil is turned off. This allows the flow of outside air into the house and in and around it. The air flowing under a house reduces the R value of the house, because it is another way for heat to enter or leave the house. Also, because this house is made of metal,is a better conductor of heat than other materials, also decreases the R value of the house. The decrease in R value of the house, most of the units of heat / cold. This home has a very low R-value.
The wooden building in the second little pig saw on a slab that was poured on the floor. Distance from the floor of the house to a relatively uniform temperature throughout the summer of the year, and winter. The walls are panels of boards of thickness cmpay less than the heat conduction as well. However, without the addition of insulation, the home or conduct heat as easily. The R-value is greater in this house the house of metal. It 'possible that this house can use a small unit of air that the house of metal.
Finally, we arrived at the brick house built on a slab of concrete blocks and building stone cutter 10 inches on the third little pig lived in. Although the house has a wooden roof, is built in wood with a thickR-value higher than that of the wooden house, with tiles and a tile that is better designed to reflect heat instead of absorbing it. Since the house is a concrete slab, no flow of outside air below. The 10-inch wall works well to isolate the heat by conduction. These materials have to work in this house with a very high value of R. This high R-value makes the house to have the internal air temperature for a longer period of time. This means that asmall air conditioning units can be used in this house that the previous two.
How is an isolated house plays a key role in the amount of heat must be moved to keep the house cool or warm. To make a central air conditioning work more efficiently as possible, better insulation of walls, floors, ceilings, doors and windows are the key. If these things are used, then a house is on the way to becoming a home "green." The air conditioner runs less often, and will last long enoughtime to cool the house enough and use less energy as possible.

An HVAC contractor can determine the size of the air conditioner to install in your home, but this record is the best size for your home? There are many variables to consider when a new unit installed in your home. These variables are grouped into a load calculation performed by your contractor or mechanical engineer. How are you? What can an engineer: a bigger house with a smaller unit than it is in another housesquare feet, in some cases?
We will use the three little pigs as an example (with some artistic license). Life in a pig before a house of metal found on a pier of four inches of soil. The second pig life in a wooden house located on a slab of concrete has been poured into the ground. Finally, the third little pig lives in a house built with masonry block 10 cm thick, is also on a slab. None of the houses are insulated. All these houses have the sameinternal dimensions, but they load calculations, which means that everyone can have a different size air conditioner.
A load calculation is a mathematical function developed to determine the amount of heat that must move to cool or heat a home. The main reason for differences in the calculation of the load is called R-value of any home. R-Value is a measure of thermal resistance ("R" word comes from the resistance) of asubstance or object. Although it may not be able to determine the R value of your home, you can easily understand the concept of taking a look at each of the pigs 'houses'. "
The metal frame of the life of the pig is first off the track. This allows air to flow out under the house in and around it. The air flowing in a house down the R-value of the house because there is no way for heat to enter or leave the house. Also, because this house is made of metal,is not a better conductor of heat than other materials, which also lowers the R value of the house. The bottom of the R-value of the house, the majority of units required for hot / cold. This home has a very low value R.
The wooden building is the second pig living on a slab that was poured on the floor. The distance from the floor of the house a relatively uniform temperature throughout the current summer, and winter. The walls are made of wooden boards, panels of an inch thickmeans less heat conduction as well. However, without the addition of insulation in this house, the unit of heat or easily. R-value in this house is more than the house of metal. It 'possible that this house you can use a small central unit air-conditioning at the home of metal.
Finally, we arrived at the brick house built on a concrete slab and built a masonry block 10 "the third little pig alive Even though this house has a wooden roof, is made of wood with a thickR-value higher than that of the wooden house covered with tiles and wooden boards with a superior quality that is designed to reflect the heat instead of absorbing it. From this house is located in a concrete slab, no flow of outside air below. The 10-inch walls work well to insulate against heat conduction. These materials all work in this house with a very high value R. This makes the R-value of the house to take whatever the internal air temperature for a longer period of time. This means thatsmall air conditioning units can be used in this house that the previous two.
How is an isolated house plays a key role in the amount of heat must be moved to keep the house cool or warm. Because of a central air conditioner work more efficiently as possible, better insulation of walls, floors, ceilings, doors and windows are the key. If these things are used, a home is on track to become a home "green." The air conditioner runs less frequently, and will run as requiredlong enough to cool the body and the use of energy as possible.
