SIDE MOUNTED REFRIGERANT DISTRIBUTOR IN A FLOODED EVAPORATOR AND SIDE MOUNTED INLET PIPE TO THE DISTRIBUTOR

摘要

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.

1. A heat exchanger for a heating, ventilation, and air conditioning (HVAC) unit, comprising:
a shell; a tube bundle inside the shell; a refrigerant distributor inside the shell; a refrigerant inlet through the shell and in fluid communication with the refrigerant distributor; and a refrigerant inlet piping mounted on the shell and in fluid communication with the refrigerant inlet; the refrigerant inlet is positioned on a side of the shell at an angle away from the bottom of the shell, and the refrigerant inlet piping is positioned on a side of the shell at an angle away from the bottom of the shell, wherein the refrigerant distributor comprises a baffle distribution component with a panel structure that forms a cavity, the baffle distribution component has baffles between which are openings in fluid communication with the cavity; a main distribution component with a panel structure that forms a cavity, the main distribution component has openings through the panel structure and in fluid communication with the cavity of the main distribution component, the main distribution component is arranged inside the baffle distribution component, where the openings of the main distribution component are in fluid communication with the cavity of the baffle distribution component, and where the cavities and openings allow refrigerant to flow into the heat exchanger.
