“A split-system air conditioner, also known as a ductless mini-split air conditioner, is a type of HVAC system that is designed to cool a single room or small area. It consists of two main parts: an indoor unit, which is installed inside the room, and an outdoor unit, which is installed outside the room. The indoor unit contains an evaporator, which is responsible for removing heat and moisture from the air inside the room. It contains a refrigerant, which is a substance that absorbs heat when it evaporates. The refrigerant is circulated through a series of coils, which are cooled by a fan. As the refrigerant absorbs heat, it evaporates and cools the air inside the room. The outdoor unit contains a compressor, which is responsible for pumping the refrigerant through a series of coils, which are cooled by a fan. As the refrigerant releases heat, it condenses and becomes a liquid again. The two units are connected by a small refrigerant line, which carries the refrigerant back and forth between the units. The refrigerant is cooled and compressed in the outdoor unit, and then evaporated and cooled in the indoor unit. The split-system air conditioner also has a thermostat, which is used to control the temperature inside the room. When the thermostat senses that the room temperature has risen above the desired setting, it sends a signal to the compressor to start running. As the compressor runs, it cools the refrigerant, which cools the air inside the room. Once the room temperature has dropped to the desired setting, the thermostat sends a signal to the compressor to shut off. Overall, a split-system air conditioner works by using a refriger”
