Warm air from the room blows over and is absorbed by the coils. How Does a Ductless AC System Work? Split vs window AC. Now, more than 87 percent of houses are so equipped. In some ways it is a simpler system and allows better zone control. The Split System Heat Pump Similar to a split HVAC system, the split system heat pump has indoor and outdoor components that work together. The expansion valve is what really does the work of cooling. They are uncommon, but not through any fault or flaw. These units are joined by a set of copper tubing known as a “line-set,” which transfers refrigerant from one unit to another. A multi-zone mini-split functions just like a single-zone system, but heats or cools more parts of a business or home. Both of these elements exist is more common central air units and wall air conditioners. The mini split itself is an efficient, quiet-running system. As the hot liquid refrigerant passes through a tiny opening at high pressure in the valve on one side, it emerges as a cool low-pressure mist on the other side. This combines the efficiency and customization of a space heater or fan with the convenience of central air. At their heart, ductless mini-split air conditioners use the same technology as the air source heat pumps used in millions of central cooling and heating systems. This also causes heat in the gas to rise. Traditional split systems consist of two main units: an outdoor and indoor unit. Mini-Split systems are becoming more popular, but are they worth the money?
