●Offers a cooling and heating capability using either cold water and hot water through the operations of the heat pumps with the compressors (finely responds to load fluctuations per rooms).

●Quickly cools the areas near the windows, as well as heats the rooms when the system is started up.

●Shows twice the capability of FCU even with the same water quantity in the powerful operations.

●Keeps the inside of the rooms pleasant with the operations in the dry mode through which the room environments are cooled and dehumidified by the fan coils and re-heated by the heat pumps (excluding some models).

●Recovers the excess heat in the building to uses it as the heat source for air conditioning when operated in the reverse mode.

●Operates individually in necessary locations per units.

●Offers earth friendly air conditioners through a fully sealed refrigeration cycle that does not emit chlorofluorocarbon at all (excluding some models).

●Simple packaging using cardboard. Neither wood frames nor foamed materials are used.

●Eliminates mixed heat loss since cold water and hot water are not used at the same time, offering an energy saving property compared to four pipe systems.

●Reduces the initial and running costs for the piping and pumps.

●Keeps the room environments comfortable, offering easy switching of the heat source during seasonal transition periods.

Energy saving property

Although four pipe systems are year-round individual air conditioning systems, the owners of the buildings have to bear large facility costs and their running costs, since cold water and hot water are supplied simultaneously throughout the year.

Offers a year-round individual air conditioning system that has almost the same capability as a four pipe system, using the existing two pipe system. PAFMAC units and fan coils can be installed together.

Four-pipe cold and hot water system

A two pipe system operates in the same mode in the entire building, where the cooling mode and the heating mode are switched seasonally.

We offer economical two pipe systems that make it possible to provide comfortable environments which previously were only achieved by ordinary four-pipe cold and hot water systems.The “PAFMAC systems” can provide an individual, free-cooling and heating capability by dispersedly arranging the units, in which the fan coils and the heat pumps are integrated, in two-pipe cold and hot water circuits.The PAFMAC units are the individually dispersed, hybrid air conditioners that have been designed to provide comfortable environments while saving energy by effectively controlling the fan coil and heat pump circuits to meet the cooling and heating demands that change from moment to moment.

Requires large transfer power, resulting in large mixed heat loss.
