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

Placing an evaporator pressure regulator between the suction line manifold and the outlet of the warmest evaporator is essential for controlling the refrigerant flow and ensuring efficient operation. The evaporator pressure regulator helps maintain the pressure within the evaporator, which allows the warmest evaporator to operate at optimal conditions.

By regulating the pressure, it prevents the evaporator from flooding with excessive refrigerant, which can impede heat exchange efficiency. This position allows for better control and distribution of refrigerant to multiple evaporators, ensuring that the system maintains the desired temperature levels throughout.

Moreover, it enables the warmest evaporator to have sufficient refrigerant to absorb the heat, while at the same time allowing the other evaporators to operate efficiently without being starved of refrigerant. This role is crucial to maximizing system performance and ensuring balanced cooling across the multiple evaporators involved.
