In a multiple evaporator system, which component should be placed between the suction line manifold and the outlet of the warmest evaporator?

In a multiple evaporator system, placing an evaporator pressure regulator between the suction line manifold and the outlet of the warmest evaporator plays a crucial role in maintaining proper system balance and efficiency. The primary function of the evaporator pressure regulator is to ensure that the evaporators operate at the correct pressure and temperature levels by controlling the suction pressure that returns to the compressor.

This component effectively prevents any one evaporator from starving or overfeeding the refrigeration cycle, thus allowing for optimal performance across all evaporators in the system. When the warmest evaporator is connected to the suction line, it influences the overall suction pressure. By utilizing an evaporator pressure regulator at this juncture, it helps to mitigate the variations in load across the evaporators, maintaining a steady state and maximizing the system’s efficiency.

The other components listed serve different functions and are not suited for this specific placement. A liquid line filter drier is designed to remove moisture and contaminants from the refrigerant, while the compressor is responsible for compressing the refrigerant vapor before it returns to the condenser. The condenser's role is to reject heat from the refrigerant after it has absorbed heat from the evaporators. Each of these components contributes to the overall operation of the cooling system but
