Bitzer screws in novel data cooling project


GERMANY: Italian company HiRef SpA is applying Bitzer screw compressors to amazing a computing centre adiabatically with air-to-air warmth exchangers. 

HiRef SpA, a specialist in air conditioning devices for information centre and telecoms, had the process of designing a cooling program in cooperation with Cooltec Techniques Kälte Klima GmbH for a computing centre in the German town of Offenbach. 

A very long-term customer of Bitzer, HiRef observed a sustainable refrigerant being of essential great importance, along with high effectiveness at complete and section load. HiRef opted for an unconventional solution – for the first time, 96 screw compressors with external frequency inverters were set up in the 48 cooling units in its place of scroll compressors. These use R513A but can be transformed to use the minimal GWP HFO refrigerant R1234ze at a afterwards day.

As one of the initial HiRef units with the adiabatic program, this challenge was of specific significance. “We needed there to be no doubt that the top quality of our environmentally friendly and sustainable remedy surpasses everybody else in the market – that is a different cause why we applied screw compressors as a substitute of scrolls,” discussed HiRef business director Wolfgang Fels. 

With screw compressors, selected temperature concentrations can be preserved exactly and regularly. If the preset most temperature established issue is exceeded, the evaporative cooling system lowers the condensing temperature and thus the electricity consumption. Pace-controlled by frequency inverters, the screw compressors provide whole mechanical backup for the cooling capacity. 

“Capacity control will make the screw compressors really strength successful at entire and aspect load,” Fels extra.

Every program has a cooling capacity of 200kW and is fitted with EC followers and a distinctive significant-effectiveness crossflow heat exchanger with a corrosion resistant epoxy coating. The double-ended parallel electrical feed has a rapid-commence attribute as perfectly as uninterrupted handle of the power provide. 

The cooling approach is centered on three distinctive concepts: full cost-free cooling with a wintertime bypass, demands-based mostly, modulating, mechanical cooling with maximised totally free cooling, and modulated, mechanical cooling with an adiabatic spray technique in the condenser.

The integrated oil separator in the Bitzer CSH65 screw compressors and the designed-in suction-fuel-cooled motor simplify method integration and, in accordance to Bitzer, make it possible for for a compact, charge-economical method layout. 

Moreover reduce lifetime cycle charges and 24/7 reliability below any operating circumstances, seem insulation was of critical significance in this challenge. The compressors’ distinctive enclosure assures optimum sound insulation, although the built-in pulsation mufflers decrease sound on the exhaust air aspect.

Having said that, when the outside the house temperature rises to all-around 20°C, the Adtec-D switches to adiabatic cooling method. The incoming air is then passed via the Condair ME, which evaporates drinking water into the contemporary air stream, cooling it by up to a further 12°C.

By combining no cost air and evaporative cooling, Weatherite’s Adtec-D has recently been able to completely exchange DX mechanical cooling throughout more than 800 switchgear rooms for a primary Uk telecoms supplier. A whole of about 1,500 Adtec-D units have been deployed in the challenge to day. 

A solitary legacy 30kW DX and absolutely free air cooling device was consuming close to 71,000kWh on a yearly basis to manage the needed internal temperature, operating 24/7. The substitution 30kW Adtec-D cooling device consumes just 14,000kWh to fulfill the similar annual cooling load. This resulted in an 80% electricity conserving for the client, which is a significant 83.3MWh annual saving in energy across the British isles-vast retrofit undertaking.

Obtainable in modules that can present from 15 to 80kW of practical cooling, the Adtec-D will generally operate with an electricity performance ratio increased than 15, even at peak outputs. 

“The evaporative cooling technological innovation, equipped by Condair, guarantees the Adtec-D can keep the allowable ASHRAE disorders, even in the course of the hotter months in a European weather without having the reliance on F-gas refrigerants,” claimed Weatherite technical supervisor Andy Lewis.
