Air Conditioning Split Units

Air conditioning split units are a type of air conditioning system that is composed of two separate units, an outdoor unit and an indoor unit. The outdoor unit is usually installed outside the building, while the indoor unit is installed inside the building. The outdoor unit contains the compressor, condenser, and expansion valve, while the indoor unit contains the evaporator, blower, and fan. The two units are connected by a series of copper pipes that allow the refrigerant to flow between the two units. The outdoor unit is responsible for removing heat from the air and transferring it to the refrigerant, while the indoor unit is responsible for blowing the cooled air into the building. The air conditioning split units are a great way to cool a building efficiently and cost-effectively. They are easy to install and maintain, and they are energy efficient.
