Technology: Multi-scroll compressors
Solution: Air cooled
LSE is the largest range of Galletti chillers which are best in class and an industry leading chiller, offering both value and high performance suitable for industrial cooling and air conditioning applications.
Though a water chiller or heat pump is chosen on the basis of the maximum load of the system it is intended to serve, and industrial applications are normally calculated for actual thermal load demands, the actual thermal load of an air conditioning system is typically less than 60% of the rated load capacity 90% of the time – so flexibility in performance and capacity control is important to ensure energy efficiency, reduced noise and increased life-span.
The LSE range of chillers and heat pumps has therefore been developed with over 14 models with EuroVent performance from 370 to 1200 kW (650kW in heat pump mode) and uses only scroll compressors on 2 or 4 cooling circuits.
Large capacity LSE models are available upon request.
HIGH EFFICIENCY UNDER PART LOAD CONDITIONS:
The number of compressors, according to size, is 2 or 3 per cooling circuit, multiplying the capacity control steps. The high number of capacity control steps enables the unit to adapt its power to the actual needs of the system, with particular gains in efficiency under partial load conditions compared to traditional screw compressors. The control microprocessor automatically distributes the workload among the compressors, thus increasing their lifespan. During operation under part load conditions, the compressors work with oversized exchange surfaces so as to achieve more advantageous thermodynamic cycles, thanks also to the use of an electronic expansion valve, a standard feature of all models.
Cooling only – Free-cooling – Heat pump (up to 650 kW)
