摘要： 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.

摘要： A shell and tube heat exchanger having a shell having an inner surface that defines a heat exchange zone, a refrigerant pool zone is arranged in the heat exchange zone, and a plurality of tube bundles are arranged in the heat exchange zone above the refrigerant pool zone. The tube bundles have first and second wall members that define a tube channel, and a plurality of tubes arranged in the tube channel. Each of the first and second wall members have a first end that extends to a second end that is spaced from the refrigerant pool zone. The plurality of tube bundles is spaced one from another so as to define one or more vapor passages. A refrigerant distributor is positioned above the tube channel. The refrigerant distributor delivers a refrigerant onto the plurality or tubes toward the refrigerant pool zone.

摘要： A heat exchanger includes a shell, a refrigerant distribution assembly, a heat transferring unit and a canopy member. The refrigerant distribution assembly receives a refrigerant that enters the shell and discharges the refrigerant. The refrigerant distribution assembly has at least one outermost lateral end. The heat transferring unit is disposed below the refrigerant distribution assembly so that the refrigerant discharged from the refrigerant distribution assembly is supplied to the heat transferring unit. The heat transferring unit includes a plurality heat transfer tubes. The canopy member includes at least one lateral side portion extending laterally outwardly and downwardly from a position above the refrigerant distribution assembly. The lateral side portion has a free end disposed laterally further from a vertical plane than the refrigerant distribution assembly, and lower than an upper edge of the outermost lateral end of the refrigerant distribution assembly.
