Hiwall Hiross for Telecom High Performance Air Conditioning
Hiwall, Hiross operation and maintenance solution ENERGY SAVING All the Hiwall units are available with the freecooling option which: provides considerable savings in electricity by exploiting low outdoor temperatures; limits the number of compressor starts and stops, thus reducing overall use of the unit. EMERGENCY OPERATION In the event of a power failure (230V), the Hiwall units can use an emergency d.c. power supply at 48V ensuring ventilation and, if required, freecooling. This means that it is not necessary to install other accessories (e.g. fans and additional control systems). EXTERNAL INSTALLATION COMPACT DESIGN The Hiwall units are particularly compact and easy to install and are fitted outside the container or telephone exchange to be conditioned. This means that the maintenance personnel can inspect the units without having to enter the room. CONTROL AND SUPERVISION The Hiross units are provided with Microface and Hiromatic, a microprocessor designed and produced by Hiross which constantly records all machine operation parameters and data with maximum precision; it can also be integrated in telecommunications network supervision systems.

Air control in small Telecom environments Air conditioning inside small telephone exchanges and shelters for telecommunications must: utilise the minimum amount of space limit energy consumption guarantee maximum safety in control of the environmental parameters operate with maximum reliability even in extreme climatic conditions be simple to install have remote control and monitoring functions
INDOOR/ OUTDOOR TEMPERATURE DIFFERENCE <9 C INDOOR/ OUTDOOR TEMPERATURE DIFFERENCE >9 C COOLING CIRCUIT The Hiwall conditioners are provided with hermetic compressor. The evaporation temperature control system guarantees start-up even when the internal temperature is high. The large-size condensing section is provided with fan speed modulation system which means that the unit operates even with low outdoor temperatures. Cooling with compressor Freecooling operation FREECOOLING The freecooling option is activated when the difference between the internal set and the outdoor air temperature is greater than 9 C (or the pre-set value). An internal damper provides for the intake of fresh air in order to reach the required cooling capacity. The treated air is expelled via the unit. kwh 600 500 400 300 200 100 WITH FREECOOLING WITHOUT FREECOOLING ENERGY SAVING >50% 0-30 -25-20 -15-10 -5 0 5 10 15 20 25 30 35 40 Energy consumption kwh vs. Outdoor temperature [ C] Savings possible with the Freecooling option Performance and technical data Hiwall Model GO04 GO05 GO08 GO10 GO13 Treated air flow rate m 3 /s 0.35 0.35 0.86 0.86 0.86 Cooling capacity (1) total kw 4.3 5.1 7.7 10.5 12.6 sensible kw 3.8 4.3 7.7 9.2 11.7 Compressor rotary rotary scroll scroll scroll Total power absorbed kw 1.4 1.8 2.5 3.3 4.1 Electrical power supply V/Ph/Hz 230/1/50 230/1/50 400/3+N/50 400/3+N/50 400/3+N/50 Electrical heating (opt.) kw 4.0 4.0 6.0 6.0 6.0 Sound pressure level db(a) 46 47 53 54 55 Width/Depth/Height mm 750/400/1400 750/400/1400 1000/500/2000 1000/500/2000 1000/500/2000 Weight kg 117 117 206 210 218 Note: (1) Outdoor temperature 35 C; return air conditions 27 C, 47% R.H.
