Final answer:
The type of metering device used on a multiple evaporator system is a thermal expansion valve (TXV).
Step-by-step explanation:
The type of metering device that is normally used on a multiple evaporator system is a thermal expansion valve (TXV).
A temperature and pressure-sensitive valve (TXV) regulates the amount of refrigerant that enters the evaporator coils. It contributes to maintaining ideal cooling performance by controlling the flow of refrigerant.
Each evaporator in a multiple evaporator system, like in a refrigerator with distinct compartments or an air conditioning system with multiple cooling zones, usually has its own TXV to regulate the refrigerant flow and cooling for that particular area.
