What are the two types of high pressure receivers based on how liquid flows into them?

The correct choice identifies the two types of high pressure receivers based on how liquid flows into them as surge and through type. Surge receivers are designed to accommodate fluctuations in liquid flow, providing a buffer that helps manage the pressure and volume of refrigerant entering the system. They typically have an internal configuration that allows for the smooth accumulation and release of liquid refrigerant, preventing excessive pressure variations that could lead to system inefficiencies or damage.

On the other hand, through type receivers are designed for a more continuous flow of liquid refrigerant. Liquid enters and exits the receiver in a more direct path, facilitating a steady movement of refrigerant through the system. This type is often used in applications where a consistent flow is necessary to maintain system performance.

Understanding these types is vital for selecting the appropriate receiver based on the needs of a refrigeration system and the flow characteristics required for optimal operation.
