An energy saving Fujitsu Air Conditioning (UK) AirstageTM V-III VRF heat pump system, complete with 12 indoor cassette units, has been installed at Yum-Sa Thai restaurant in Putney.

The completed VRF air conditioning system comprised a V-III two-pipe heat condensing unit connected to nine 600mm x 600mm four-way compact cassettes, as well as three 840mm x 840mm four-way ‘slim type’ cassettes.

The cassettes were painted dark grey to match the interior design of the restaurant, prior to being suspended from its exposed ceiling. Pipework was laid to a painted cable tray, while the condensing unit was positioned on a concrete ledge in the venue’s underground car park, but with full exposure to the open atmosphere.

Fujitsu’s AirstageTM V-III two-pipe heat condensing unit (AJY126LALBH) has a 40kW cooling capacity, boasts a smart, cutting edge design and can be connected to up to 30 indoor units. A flexible communication method and piping connections ensure ease of installation and maintenance, even as part of a large system.

The 600m x 600m compact cassettes used in Yum-Sa were Fujitsu’s AirstageTM AUXB07GALH and AUXB12GALH models, which have capacities of 2.2kW and 3.6kW respectively. There was also an 840mm x 840mm AUXD24GALH cassette, featuring a slim, low height design for circumstances of limited space inside a ceiling void.
