Carel was recently selected as the winner of the coveted AHR Expo Innovation Award in the Refrigeration category for its HEOS Sistema solution.
The 2016 AHR Expo Innovation Awards recognize the most creative, effective, and ingenious HVACR products and technologies on the market. Winners are chosen by a panel of third-party ASHRAE member judges in each of 10 product categories based on innovation, value, and impact on the marketplace.
Carel Group CEO, Luigi Nalini, said the HEOS Sistema Controller is the most technologically advanced, high-efficiency solution for the management of refrigerated cases and cold rooms for the food retail industry.
“The classic architecture of a compressor rack supplying the refrigerated cases with long distribution lines can be replaced by HEOS Sistema featuring remote showcases fitted with variable-speed BLDC compressors cooled by a water loop,” he said.
Each unit is fitted with its own BLDC compressor, can adapt its operating pressure to the load conditions in real time, allowing the compressor to operate in the most energy-advantageous conditions at all times.
The heat of condensation from the refrigerated cases is carried outside of the store via a simple water loop, which in turn is cooled by an outdoor free cooling device. The water loop can be integrated into the HVAC management system, allowing advanced heat recovery functions and consequently savings in both cooling and heating operating modes.
The Heos Sistema solution brings energy savings of up to 25 per cent when compared against a traditional low-tech solution or a similar solution with stand-alone units fitted with ON/OFF compressors. In addition, integrating this technology into the air-conditioning ensures better overall system efficiency.
The use of remote units means elimination of long copper piping for the refrigerant circuit. The result is a reduction of system refrigerant charge of up to 80 per cent and a reduction in refrigerant leaks of up to 96 per cent.
