Operate ammonia refrigeration plant

KHU-ELT-0436

This unit involves the skills and knowledge required to operate ammonia (R717) refrigerant refrigeration plants. It includes operating an industrial refrigeration plant using ammonia as the refrigerant. It also includes applying specialised refrigeration principles that apply to ammonia, specifying the normal operating parameters for the plant, rectifying faults and defective components within organisational guidelines, and completing the necessary service documentation. The skills and knowledge in this unit will be applied by ammonia refrigeration plant operators during the start-up, operation and shutdown of ammonia refrigeration plants. The skills and knowledge described in this unit require a licence or permit to practice in the workplace where work is carried out on electrical installations which are designed to operate at voltages greater than 50 volt (V) alternating current (a.c.)
