Abstract
A refrigeration machine and a method of charging the same. The machine comprises a compressor, a condenser, an expansion device, and an evaporator connected together to form a closed loop, vapor compression refrigeration circuit. The condenser includes first and second parallel refrigerant condenser coils, and refrigerant is condensed with greater efficiency in the first condenser coil than in the second condenser coil. The refrigeration machine further comprises a first sight glass for disclosing the presence of refrigerant vapor in the refrigerant fluid discharged from the first condenser coil, and a second sight glass for disclosing the presence of refrigerant vapor in the refrigerant fluid discharged from the second condenser coil.
