History of the ductless mini split.

The ductless mini-split air conditioner (DMAC) a cooling system that first gained popularity in Japan in the 1970s. DMACs consist of two main components: an outdoor compressor/condenser unit and one or more indoor air handling units. The outdoor unit is connected to the indoor units via small diameter pipes called linesets, which carry refrigerant and covered and protected by lineset covers.. DMACs are different from conventional air conditioners in several ways. For one, they do not require ductwork, which makes them much easier to install. They are also much more efficient than conventional systems, due in part to their use of inverter compressor technology.

Inverter compressors are able to adjust their speed to match the cooling or heating load of the indoor unit, which results in lower energy consumption and less wear and tear on the compressor. Because DMACs do not require ductwork, they are also less likely to leak air, which further increases their efficiency. Due to their many advantages, DMACs have become increasingly popular in recent years, especially in Asia, Europe and now the USA. Unlike centralized forced-air systems, which use a single blower fan to circulate cooled or heated air throughout a building via a system of ducts, each indoor unit in a DMAC system has its own blower fan. This allows for much greater control over the temperature in different parts of the building. zone control.

The outdoor compressor/condenser unit of a DMAC system is connected to the indoor units via refrigerant lines (which can be up to 50 feet long). These lines allow for heat exchange between the indoor and outdoor units. When the system is in cooling mode, the heat exchange process removes heat from the indoors and transfers it outdoors. When the system is in heating mode, the heat exchange process removes heat from outdoors and transfers it indoors. The advantage of this heat exchange process is that it is much more efficient than that of a centralized forced-air system, which uses a furnace to generate heat (or an air conditioner to remove heat). In a DMAC system, there is no need for a furnace or an air conditioner because the heat exchange process takes place between the outdoor and indoor units.



The history of the ductless mini-split air conditioner is certainly interesting and DMAC's are gaining ground to become the preferred solution when upgrading heating & cooling. The ductless mini-split air conditioner (DMAC) is a highly efficient and effective way to cool or heat your home or office. If you are thinking about installing a DMAC system in your home or office, be sure to contact a qualified HVAC technician who can help you choose the right size and type of system for your needs.
