Ductless air conditioner units (AC units) are becoming popular because people want to save money on their monthly air conditioning bills, and also in cases where they want to remodel an older building with no space provided for expansive air ducts.
This ductless air conditioning review will help you get a basic grasp on ductless air conditioners. After reading this brief report you will be able to figure out whether a duct-free AC units might be right for the needs of air conditioning your home.
1. Ductless air conditioning systems are also known as mini-split systems. The genius of ductless air conditioning is in separating the cooling, or the evaporating, inside, unit, from the compressor, or condenser unit outside. That way, the noise stays outside the room while the cooling effect is present and effective. In fact, the noise of the inside unit can be compared to that of the noise of a ceiling fan, or less. The inside unit is really whisper quiet. That compares favorably with through-the-wall AC units or window AC units.
2. Ductless air condition works not unlike a refrigerator. A refrigerant liquid is compressed in the outside unit, then transported to the inside unit. There it is rapidly expanded, causing extreme cooling of the coil. A blower blows the room air over the cooled coil, causing the heat to be transferred from the room air to the refrigerant liquid. That heated liquid is then transported to the outside unit, where it is compressed, condensed. The cycle then repeats itself. The only condition for effective operation of a cooling cycle is that by expanding the refrigerant liquid, the temperature of that liquid gets to be lower than the temperature of the room, and that compressing that refrigerant in the outside unit, the temperature becomes higher than the outside temperature. When these conditions are met, the unit will work effectively.
3. Energy savings of a ductless AC system. The energy savings of a split ductless AC system mainly stem from the fact that you can control a single room in a house if you choose to. Cooling is regulated for each inside unit through a convenient remote control, or using timers which, again, are room specific. This results in additional ductless air conditioning cost savings. Another efficiency of mini-split AC units as compared with the ducted air conditioning systems, is that there are surely no losses of energy in ducts. The third source of energy savings with a ductless air conditioner is the physical separation of the condenser and the evaporator units.
