INCORPORATING COLD CHAIN
PROJECT
Alternate view of LT Bitzer racks on sides , Ammonia vessels , LT on left , intercooler vessel on right . applications in industrial and commercial markets to meet the growing demand for high efficient , natural refrigerant solutions .
ELEMENTS OF DIFFICULTY ON THE PROJECT The processing plant had to be constructed inside a historical building with concrete trusses and roofs . Central Specialist Group had to develop special clamp on brackets to hang the primary pipe support steel from the trusses .
Pipe routing had to be planned according to the loading capabilities of the existing structure and void heights . The processing facility also needed to be constructed with stainless steel insulated panels and trimmings for food hygiene reasons and was required to be durable due to exposure on a daily basis to high-pressure washing .
SYSTEM IMPACT ON ENERGY EFFICIENT AND SUSTAINABLE The system has been designed with optimized condensing and evaporation temperatures to optimise system coefficient of performance ( COP ). The natural refrigerant ammonia had been set as the preference for its highest efficiency , longest plant life expectancy and sustainability aspects having a zero global warming and ozone depletion potential . Bitzer screw packs have optimal working-hours between major service intervals , providing low life cycle cost .
With the recovery of waste heat from the refrigeration plant , the client is saving on coal consumption in the steam plant and ensuring that the total installation reaches peak environmental sustainability .
