For server rooms

“P” Series air conditioners for close control applications are specialised machines with design and operating features which clearly differentiate them from standard air conditioning units.

Though optimised for use in data centers and telephone exchanges, they are equally valid in special applications such as measurement laboratories, TV recording studios, museums, control rooms for electricity power stations and railway junctions and other areas where there are prevalent sensible thermal loads and crowding is negligible.

Their application is also ideal in widely varied industrial sectors: optics, electronics, electromedical equipment, electronic equipment production, musical instrument production etc.

Johnson Controls’ “P” Series design offers the highest sensible cooling capacity with the minimum footprint possible, which translates into optimal ratio levels of cooling capacity to footprint area.

YC-OPA, YC-UPA models for pairing with remote condensers.

YC-OPA and YC-UPA air conditioners in self-contained packaged

format with built-in water-cooled condensers.

YC-OPW…/FC, YC-UPW…/FC air conditioners are equipped with a “Free cooling” system consisting of an additional chilledwater cooling coil integrated in the aluminium fins of the unit’s direct expansion one, with a three-way modulating valve controlled by the modulating controller. As long as the outside conditions allow the water to respond totally or partially to the cooling request, the controller cuts out or minimises the compressors’ intervention, so reducing substantially the energy consumption.

This system consists of the same chilled-water cooling coil as the “Free cooling”, but fed by the building water chiller. A built in frigorific circuit enters in operation in case of lack of chilled water. The result is the maximum security or a remarkable reduction of both consumption and running costs. This system can also use the direct-expansion coil circuit as primary cooling source and, in case of an emergency, the chilled-water coil connected with the tap water network. The “Two Sources” version is available for units with direct expansion circuit YC-OPA…./TS, YC-UPA…./TS as well as units with built in water cooled condenser (accessory) and with double chilled water coil YC-OPU…/TS, YC-UPU…/TS: one for district water and the other for tap water or water from a chiller (emergency).
