XFreeCooling heat-pipe air conditioning: modes, condensers and climate fit

XFreeCooling is Envicool's inverter heat-pipe air conditioning for data centres. It switches between three modes: compressor cooling, turbopowering heat-pipe free cooling and refrigerant-pump heat-pipe free cooling. The unit has a DC variable-frequency compressor, EC speed-controlled fans and a V-shaped evaporator, and it pairs with several condenser and pump arrangements. Turbopowering technology and an evaporative spray component are options you choose.

Envicool's illustration shows a cabinet-style indoor unit and an in-row-style terminal; your quotation lists which of them you receive. Envicool states more than 60% free-cooling time, up to 70% annual saving and pPUE figures for northern and southern regions. Those depend on climate and load, so ask for a calculation on your own weather file. CyberMate V is a separate product line with a different architecture. Send the room load and air conditions, the layout and the planned condenser position for a selection.

Selection and application

Mode and option package

State whether your order includes turbopowering, the refrigerant pump and the spray option, and ask for the schedule of the indoor unit, compressor, fans and condenser. The feature list on the product page describes the range; the schedule describes your order.

Request the switch points between compressor cooling and each free-cooling mode at your load and climate. Free cooling still uses pump and fan energy, and the compressor runs whenever outdoor conditions fall short of the switch point.

Indoor unit and condenser as one selection

Send the air-side load and conditions, the layout and where the condenser will stand. Get the indoor rating paired with the actual condenser and pump arrangement at the ambient points that matter. Conventional and centralized condensers differ in footprint, connections and total input, so compare them on selected documents.

Ask for pipe length and height limits, the refrigerant charge, service isolation and any network controls. Clarify which terminal, pump, condenser and accessories are supplied.

Spray water and cold weather

With spray selected, ask for water quality, consumption, drainage and treatment, and maintenance at the weather points where spray runs. Without spray, use only the dry ratings.

Request instructions for cold weather, idle periods and mode changes, with capacity at the site's environmental limits. The regional efficiency figures cover broad northern and southern climates; ask for a performance map for your location.

Free-cooling hours and pPUE on a stated boundary

For an annual figure, ask Envicool for the weather file, IT load profile, air conditions, comparison equipment and the power counted. List compressor, fan, pump, condenser and spray loads in total input. A pPUE covers the cooling subsystem; whole-facility PUE is a wider figure.

Accepting the modes and the backup

Agree capacity and input measurements at mechanical and free-cooling points, and test the mode transitions, control interfaces and fault response. Define redundancy from the actual equipment and power layout. Obtain drawings, commissioning instructions, spares, warranty and sound at the ordered duty.

Mechanical cooling

Paired indoor and condenser capacity and total input at the limiting ambient.

Heat-pipe modes

Pump and turbopowering options ordered, with the mode-transition thresholds.

Annual assessment

Your weather, load and energy boundary in place of the regional pPUE figures.

Confirm in writing before ordering XFreeCooling

Ask Envicool to confirm in writing: the indoor terminal type and condenser arrangement; whether turbopowering, the refrigerant pump and spray are included; capacity in each mode at your weather points; transition thresholds; pipe limits and refrigerant charge; spray water needs; the annual hours and pPUE calculation for your site; and the price and production slot.
