Abstract
A heating, ventilation, air conditioning, and refrigeration (HVAC&R) system includes a heat exchanger with a shell having a first pass configured to place a fluid in a heat exchange relationship with a first refrigerant and a second pass configured to place the fluid in a heat exchange relationship with a second refrigerant. The heat exchanger also includes a water box coupled to the shell and configured to direct the fluid from the first pass to the second pass. The HVAC&R system also includes a fluid mixing manifold disposed within the water box, where the fluid mixing manifold is configured to collect and mix a plurality of flows of the fluid from within the water box to generate a mixed fluid, and a sensor coupled to the fluid mixing manifold, where the sensor is configured to measure a parameter of the mixed fluid.

A heating, ventilation, air conditioning, and refrigeration (HVAC&R) system, comprising:
- a heat exchanger comprising a shell having a first pass configured to place a fluid in a heat exchange relationship with a first refrigerant and a second pass configured to place the fluid in a heat exchange relationship with a second refrigerant and comprising a water box coupled to the shell and configured to direct the fluid from the first pass to the second pass;
- and
- a fluid mixing manifold disposed within the water box, wherein the fluid mixing manifold is configured to collect and mix a plurality of flows of the fluid from within the water box to generate a mixed fluid, and the fluid mixing manifold is configured to collect the plurality of flows of the fluid via a plurality of sampling conduits of the fluid mixing manifold;
- and
- a sensor coupled to the fluid mixing manifold, wherein the sensor is configured to measure a parameter of the mixed fluid.
A heat exchanger, comprising:
- a water box configured to direct a fluid from a first pass of the heat exchanger to a second pass of the heat exchanger;
- and
- a fluid mixing manifold disposed within the water box, wherein the fluid mixing manifold comprises:
- a plurality of sampling conduits configured to collect and mix a plurality of flows of the fluid from a respective plurality of locations within the water box;
- a mixing junction fluidly coupled to each sampling conduit of the plurality of sampling conduits, wherein the mixing junction is configured to mix the plurality of flows of the fluid to generate a mixed fluid;
- and
- a discharge port fluidly coupled to the mixing junction and configured to discharge the mixed fluid into the water box.
A heating, ventilation, air conditioning, and refrigeration (HVAC&R) system, comprising:
- a heat exchanger comprising a shell, a water box coupled to the shell, a partition disposed within the shell to define a first volume within the shell and a second volume within the shell, a first subset of tubes disposed within the first volume and configured to direct a fluid into the water box, and a second subset of tubes disposed within the second volume and configured to receive the fluid from the water box;
- a fluid mixing manifold disposed within the water box, wherein the fluid mixing manifold comprises a plurality of sampling conduits, and the fluid mixing manifold is configured to collect a plurality of flows of the fluid from a plurality of locations arrayed along a height of the water box via the plurality of sampling conduits and is configured to mix the plurality of flows of the fluid to generate a mixed fluid;
- and
- a temperature sensor disposed within the fluid mixing manifold and configured to detect a temperature of the mixed fluid.
