Abstract: A combination refrigeration displacement and drain device is disclosed that can be mounted within a heat exchanger, such as a shell and tube heat exchanger, which may be used for example as a heat exchanger in a chiller unit, which may be used in an HVAC or refrigeration system. One example of such components can include heat exchangers, such as for example a condenser employing a gravity drain. Advantageously, the combination refrigeration displacement and drain device herein can provide a refrigerant charge reduction for example that is used in the chiller unit, while facilitating drainage out of the heat exchanger. The combination refrigeration displacement and drain device can alleviate the liquid refrigerant accumulation that may normally be necessary to induce flow in a gravity drain design.

Abstract: A heat exchanger, for example a shell and tube flooded evaporator, has a refrigerant distributor that is positioned at an angle between the bottom of the shell and the sides of the shell, and includes an inlet that is welded to an inlet piping, where the inlet and inlet piping are in fluid communication with the refrigerant distributor, and are in a generally corresponding position orientation. Tubes of a tube bundles may extend proximate the bottom of the shell.

Abstract: Generally, apparatuses, systems, and methods are described to vent refrigerant vapor from the refrigerant pump line using a vent line, such as during priming of the pump and/or during a startup of the compressor, directed to a relatively reduced volute casing mass of the refrigerant pump, and/or directed to returning refrigerant to an economizer or chiller component other than the condenser.
