The tool allows you to select whether the refrigerant is undergoing a phase change or all liquid, such as in a subcooler.
This tool assumes a flooded liquid configuration for phase change refrigerant
Selecting “Ammonia in the Shell” assumes that ammonia occupies the space between the head and around the tubes. Any baffles or structural supports within the shell are neglected in the total shell volume used in the tool.
This tool should only be used in the absence of manufacturers published data.
