REFRIGERANT CHARGING MEANS AND METHOD

Means and method for introducing an optimum charge of refrigerant into a refrigeration or air conditioning system. When the system is charged to optimum capacity there is a melting of frost, which indicates when the charging operation is to be stopped. This is accomplished by converting a liquid ref...

Zusammenfassung:	Means and method for introducing an optimum charge of refrigerant into a refrigeration or air conditioning system. When the system is charged to optimum capacity there is a melting of frost, which indicates when the charging operation is to be stopped. This is accomplished by converting a liquid refrigerant to a saturated vapor and feeding the saturated vapor into the low side of the refrigeration or air conditioning system.
