High precision air-conditioners for data centres cooling, with new inverter technology and R-410A refrigerant, from 6 to 150 kW

Data Center energy consumption

Cooling IT load

Coming form 40 years experience in air conditioning and

process cooling, i-ACCURATE is the ultimate solution for

technical rooms and data centres cooling:

From Climaveneta’s experience i-ACCURATE high precision air conditioners, available both as direct expansion andfree-cooling versions are the most efficientand reliable solution on the market.

Precise temperature

and humidity control

Complex IT centres require to keep temperature and humidity

within very strict parameters. This is particularly difficult due to

extremely variable thermal loads, that require very high cooling

capacity at full load, in order to avoid to compromise the correct

operation of the IT machines when they are more necessary.

The massive use of the new inverter technology on HPAC units

for technical rooms, makes possible to keep ambient

temperature and humidity constant even with very strong loads

variations, preventing dangerous temperature variations, almost

unavoidable with traditional ON/OFF compressor driven units.

High efficiency at partial loads

Most energy consumed by modern data centres is due to ambient

cooling. In more and more cases the cost due to cooling are

higher than those caused by data exchange. In systems

characterized by H24 operations, also the slightest compromise

concerning efficiency has dramatic implications in the operating

costs of the whole data centre. Hence it is crucial that the air

conditioning system of the centre works effectively also at part

loads, which are the most frequent operating condition, in order to

reduce the overall operating cost. i-ACCURATE strong point is

exactly efficiency at part loads. Thanks to the adoption of inverter

DC brushless compressors up to 30kW and inverter AC for lager

capacities, these units can reduce by 50% consumptions at part

load, if compared to a traditional ON/OFF compressor. This is

made possible also thanks to the advantages of variable air flow

enabled by last generation EC fans.

Versatility

The many types of structures used as technical areas and the

need to optimize their dimensions, require flexible solutions,

that can adapt to any room, always granting perfect control

and highest efficiency.

This means complete flexibility, both as concerns capacities

(from 6 to 150 kW Inverter), as well as configuration and

system with 5 different cooling solutions, including

FREECOOLING with R410A.

Efficiency, versatility and reliability. These are the strong points that make i-ACCURATE a point of reference in high precision air conditioning. Advantages that come from distinctive technological choices in every aspect of this units.

Inverter

technology

The inverter driven compressor, though the variable frequency, modulates the power capacity provided, hence enabling to optimize the performances at part load, increasing efficiency.Moreover a larger capacity can be reached at full load, thus ensuring that the required temperature will be reached in a shorter time. Afterwards temperature variations can be easily controlled with minimized energy consumption, because once the set is reached, the compressor works at part load, reducing energy consumption and effectively maintaining the desired conditions.

In this respect i-ACCURATE represents the ultimate solution in high precision air conditioning, with the most updated compressors, both DC inverter brushless, for units from 7 to 30 kW and Inverter AC for larger capacities. Both solutions allow to perfectly adapt the unit’s performance to the real requirements of the building even at part load, which represent more than 75% of the operating time of the system. This ensures an energy saving up to 50% higher than solutions based on traditional ON/OFF compressors.

NEW GENERATION

EC fans

The high efficiency EC fan reduces both noise levels as well as energy consumption, and assures a variable air flow at part loads, optimizing the operating costs of the unit.

Main features

Further noise level reduction 4-5 dB(A) Further absorbed power reduction by 15%

An advanced logic simultaneously manages fans and inverter compressors modulation, with savings at part loads up to 50%.

EC fans

also in the remote condensers

The use of EC technology even on the remote condenser fan assures a further average reduction of noise levels by 10%, together with a strong reduction of energy consumption by 45% compared with traditional condensers with AC technology.

Intelligent

Control

i-ACCURATE, has an intelligent regulation, that allows the complete control of all the unit’s parameters in any condition.

i-ACCURATE control is completely open and can be set according to the specific needs of the customer, either on site or in advance when the unit is produced.

Electronic

thermostatic valve

The electronic valve is used in a very peculiar way in order to guarantee optimum operating conditions at the evaporator.

The INVERTER units come with electronic expansion valves as standard. These valves have a much wider modulation capacity; it stands out for its quality of control and for its capacity to quickly reach and maintain the operating stability of the unit and joined with INVERTER compressor technology allows a quick fluctuation-free regulation, and therefore a highly accurate adjustment to the swings of load and ambient conditions.

Types of cooling

Airflow configuration

OVERThe versions called OVER with air outflow from the top generally have the air intake at the front, rear or bottom of the unit, according to customer choice, and the outflow from the top is along ducts behind suspended ceilings or front delivery plenums.

UNDERThe versions called UNDER with air outflow under the floor have the air intake on the top of the unit taking air directly from the environment or through intake ducts or plenums.

i-AXO/i-AXU

DIRECT EXPANSION AIR COOLED, with INVERTER compressor

Refrigerant for heat transfer is used in these direct expansion units. The air in the room is therefore treated in the evaporating coil containing the refrigerant. The condensation heat is dispersed to a fresh air condenser that with speed control for condensing control, optimise the condensation pressure even in adverse temperature conditions.

Units provided per standard with EC inverter fans who represents today the best solution for energy saving.

i-AWO/i-AWU

DIRECT EXPANSION WATER COOLED, with INVERTER compressor

Refrigerant for heat transfer is used in these direct expansion units. The air in the room is therefore treated in the evaporating coil containing the refrigerant. The condensation heat is dispersed in an internal plate-type exchanger connected in turn to a water circuit. The water of condensation may come from a well, local water mains or closed circuits such as cooling towers or dry coolers.Units provided per standard with EC inverter fans who represents today the best solution for energy saving.
