Everyone likes to come home to a refreshingly cool house in the summertime heat and humidity. While not everyone is fortunate enough to have central air conditioning, many people utilize window units. Still, there are places in your home that are not fit for window air conditioner units. If you’re looking for an unobtrusive way to bring more cool air into your home, a split air conditioner system might be the perfect answer for your temperature-regulating problems.What is a Split Air Conditioner System?The sleek-looking indoor unit contains the cooling coil, a long blower and an air filter.How is a Split Air Conditioner Different From Other A/C Units?A split air conditioner does not require major installation work because it does not require ductwork. Rather, the indoor and outdoor units are connected with a set of electrical wires and tubing. This is good for your wallet and the environment. The ductwork required for many traditional A/C units generally increases energy expenditures, as many centralized A/C units lose a lot of energy due to heat exchange in the air duct system.

So, without a duct system, there is very little opportunity for heat or energy loss in a split air conditioner system.used ac units pricesBenefits of a Split Air Conditioning SystemThis kind of air conditioner system has many advantages over traditional air conditioners. best ac heat pump unitsPerhaps the most obvious benefit is the quiet performance of a split air conditioner system. best prices on ac unitsThe parts of an air conditioner that make the most noise are the compressor and the fan that cools the condenser. In a split system, the compressor and fan for the condenser are located outside of the room being cooled and therefore the majorsources of noise are removed - unlike with window units.Another benefit of a split air conditioner system is that you can opt for a multi-split system, where you can have more than one indoor unit connected to a single outdoor unit.

This makes it easy to cool multiple rooms or maintain the temperature throughout a large room through the use of two indoor cooling units.A split air conditioner is an efficient and cost-effective way to cool your home. It should be noted that the initial cost of this kind of air conditioning unit is significantly higher than a window unit and it does require professional installation. However, the amount of money you will save on your energy bills as well as the longevity of the unit will make it worth your while in the end.Author Sirena Rubinoff is a writer based in California.

Direct Expansion Air Conditioning A direct expansion air conditioning (DX) system uses a refrigerant vapour expansion/compression (RVEC) cycle to directly cool the supply air to an occupied space.  DX systems (both packaged and split) directly cools the air supplied to the building because the evaporator is in direct contact with the supply air,Expansion refers to the treatment of the refrigerant (a valve reduces its pressure and temperature) prior to it entering the evaporator. 

DX systems can come equipped with all the components in the unit (packaged system) intended for installation on the rooftop or by the side of a building; or it may have some components installed inside the building and some outside (split system). DX systems require a ventilation fan to distribute the cool air and resupply/re-circulate it.  A  RVEC cycle has four basic components; an evaporator, compressor, condenser, and thermal expansion control device. The evaporator (located inside the supply air ductwork) absorbs heat through the process of expanding the refrigerant flowing within it. The refrigerant then flows to a compressor which compresses it causing it to condense in the condenser and release the heat it removed from the supply air. The condensed liquid refrigerant then flows through the thermal expansion control device which controls the flow and pressure of the refrigerant back into the evaporator.Packaged Systems – Packaged DX units contain all 4 parts of the RVEC system, as well as fans and internal ducting.

These units are designed to be installed easily to serve local zones cooling needs; multiple units can be installed to service multiple zones in a building.Split Systems – These systems generally have the evaporator and fans inside the building, while the rest of the RVEC system components are a separate unit placed outside the building. This allows system designs that are more flexible, allowing performance that can satisfy greater variations on system demands. Split units are made to an incremental performance scale, meaning only certain working load sizes are available.DX systems are less expensive to install, and uses less space in mechanical and electrical rooms than centralized cooling systemsDX systems can be expanded in an incremental fashion to match changing building requirementsPackaged Systems have standardized operating performances per unit, allowing more precise system sizingPackaged Systems generally require less ventilation, and do not require dedicated condensate linesPackaged Systems occupy less space than comparable split systemsSplit Systems tend to be larger allowing for fewer units
