For example, an interior wall would be a wall in a bedroom that shares a wall with the hallway. An exterior wall is one that shares a wall with the backyard. Equal Air Distribution: The handler must be placed in a spot that will ensure air is distributed equally through the room.
The recommended placement is at least seven feet above the ground, but as close to the ceiling as allowed. All air-conditioning uses the same outdoor components to produce the cold refrigerant that cools the air inside a home.
Central-air systems send refrigerant to a bulky central air handler that then blows cool air into the house through a network of ducts. Ductless systems pump refrigerant to compact indoor units within individual rooms.
Because there are no ducts, these systems don't have the air leaks, heat gains, or pressure imbalances that can undermine the efficiency and comfort of a central-air setup. And installation is a snap.
It's far easier and faster to fish a narrow bundle of insulated refrigerant lines through a house than to retrofit bulky HVAC ducts. Coincidentally, that's also about how much cooling is typically lost in central-air systems, thanks to leaky, poorly insulated ductwork. Beware of installers who size a split AC unit using a rule-of-thumb estimate. More often than not, the result is oversize equipment that's costly to operate and can't effectively reduce humidity levels.
It figures system size based on math and factors such as climate, insulation levels, and sun exposure. All cooling systems carry a Seasonal Energy Efficiency Ratio SEER rating, which compares cooling capacity with the amount of electricity used over the course of a typical cooling season.
Ratings on today's systems range from 13 to 33 SEER. As the graph below shows, the higher the rating, the more you'll pay for your system, and the lower your electricity bills will be come summer. To see what effect SEER ratings have on estimated operating costs in your area, go to the central AC life-cycle cost calculator at energystar. System prices come from acwholesalers. In the parlance of air-conditioning, a ton is not a measure of weight; it's a measure of cooling capacity. One ton of cooling extracts 12, Btus per hour from a space.
That's enough heat to melt 1 ton of ice within 24 hours, hence the connection between weight and comfort. All indoor split AC units include mesh filters that collect dust. An improper installation can void the warranty and cause permanent damage to the equipment.
While ductless air conditioners are extremely popular in many parts of the world, U. A local Mitsubishi Electric contractor can answer any questions and explain the steps involved in the ductless AC installation process. In addition to determining the right system size and placement options for the equipment, consultants can help identify inexpensive ways to improve the overall efficiency of the building.
Prior to selecting the equipment, a qualified dealer will run a complete set of load calculations to determine the precise capacity requirements for each heating and cooling zone.
Outdoor condensing units are matched to meet the total combined load of the indoor units. Proper ductless sizing is critical for optimal comfort, performance and humidity control. The installation of the outdoor condensing unit is a relatively straightforward process.
A concrete pad should be poured on a level base no closer than one foot from an exterior wall. Polyethylene or reinforced rubber pads can also be used in lieu of concrete. Unit connectors must face the house, and the vents should not be blocked by shrubbery or other obstructions.
Refrigerant lines are made of copper and insulated with closed cell rubber foam.
