Fujitsu Air Conditioning has upgraded air conditioning systems of HMS Belfast, the historic London tourist attraction.
Three AUXB18GALH 4-way compact cassettes and an ASYA09GACH wall-mount from Fujitsu were added. These new indoor units have been installed onto the existing AirstageTM J-IIS two-pipe heat pump VRF system, which is also from Fujitsu, in the lower deck sleeping quarters. The equipment proved to be so successful that a second, identical J-IIS system was recently installed adjacent to the first.
The new compact cassette and wall mounted units utilise the existing air conditioning pipework on board. The indoor units are now fully operational, supplying the lower deck sleeping quarters with the desired levels of heating (and cooling) as and when required.
The new air conditioning units have been installed in an open exposed arrangement, ensuring all the cassette units are suspended in the positions of the original models. The original infrared controls have also been replaced by touchscreen versions, which are hardwired to each indoor unit. The controls are set up in a master/slave arrangement, ensuring the two pipe heat pump VRF system can run either in ‘all heating’ or ‘all cooling’ mode.
Fujitsu’s AUXB18GALH 4-way compact cassette units offer cooling capacities of 5.6kW and heating up to 6.3kW. Elsewhere, the company’s ASYA09GACH wall-mounted AC unit boasts 2.8kW of cooling and a heating capacity of up to 3.2kW.
