A snap-action two-temperature valve is normally used with multiple ________ systems.

A snap-action two-temperature valve is normally used with multiple ________ systems.

• A. Evaporator
• B. Condenser
• C. Heater
• D. Chiller

Answer: (A)

This valve is designed to regulate refrigerant flow into evaporators in systems that have multiple evaporators, and it does so with two temperature setpoints and a quick snap action. In a multi-evaporator arrangement, you want rapid, decisive control of how much refrigerant reaches each evaporator so that cooling is balanced and responsive to changing loads. The two-temperature, snap-action design provides that by switching between two defined flow states as temperatures rise or fall, helping to maintain the proper evaporating temperature and prevent one evaporator from being under- or over-fed. The other options don’t fit because they refer to components on the high-temperature side or to heating equipment, whereas this valve’s role is on the evaporator side where multiple evaporators are operated together.
