The Functionality of Boiler Feedwater Valve Compared to a Refrigeration System

What part of a refrigeration system is most similar to the boiler feedwater valve?

A) Liquid receiver

B) Metering device

C) Condenser water inlet

D) Compressor discharge outlet

Final answer: B) Metering device

Answer:

In terms of functionality, the boiler feedwater valve is most similar to the metering device in a refrigeration system, as both regulate the flow of fluid in their respective systems.

Explanation: The part of a refrigeration system that is most similar to the boiler feedwater valve, in terms of functionality, is the metering device. Both the boiler feedwater valve and the metering device regulate the flow of fluid in their respective systems. The boiler feedwater valve controls the amount of water entering the boiler, while the metering device controls the flow of the refrigerant within the refrigeration system, often reducing its pressure and controlling its rate as it enters the evaporator.

In comparison to the choices provided:

A) Liquid receiver - stores excess liquid refrigerant.

B) Metering device - regulates refrigerant flow into the evaporator.

C) Condenser water inlet - is where water enters the condenser.

D) Compressor discharge outlet - is where the refrigerant exits the compressor at high pressure.

Refrigerant moves through these components in sequence, but the metering device's role in regulation most closely matches that of the boiler feedwater valve.
