Abstract: An immersion cooling system includes an electronic component, a thermally conductive dielectric liquid, and a tank defining a tank interior configured to receive the electronic component and the thermally conductive dielectric liquid for cooling the electronic component. The immersion cooling system also includes a wall positioned external to the tank to coordinate with the tank to define an overflow gap extending between the tank and the wall. The overflow gap is configured to receive an overflow of the thermally conductive dielectric liquid from the tank interior.

Abstract: A vapor compression system includes a heat exchanger configured to facilitate heat transfer between a refrigerant and a conditioning fluid. The vapor compression system also includes an expansion valve disposed along a conduit coupled to the heat exchanger. The conduit is configured to direct a flow of the refrigerant into the heat exchanger. Additionally, the vapor compression system includes a sensor configured to provide feedback indicative of a temperature of the conditioning fluid exiting the heat exchanger and a controller including a memory and processing circuitry. The processing circuitry is configured to receive a signal indicative of the temperature of the conditioning fluid exiting the heat exchanger from the sensor and adjust operation of the expansion valve based on the signal.

Abstract: A heating, ventilation, and air conditioning (HVAC) system (10) includes a flash tank (32) configured to receive a refrigerant and to separate the refrigerant into vapor refrigerant and liquid refrigerant. The flash tank (32) is configured to generate a flow of refrigerant therein along a circular flow path (132). The flash tank (32) has a main body (102) having a circular cross-section with a diameter (112) and an inlet (100) coupled to the main body (102) and configured to direct the refrigerant into the main body (102). The inlet (100) has a center line (110) extending in a common direction with the diameter (112), and the center line (110) is offset from the diameter (112) in a radial direction.

Abstract: A flooded evaporator (38) for a HVAC&R system (10) includes a shell (102) defining an interior volume (264) and a refrigerant inlet (110) configured to direct a two-phase refrigerant (106) into the shell (102). The flooded evaporator (68) includes a liquid distributor (104) disposed within the interior volume (264) of the shell (102) and configured to receive the two-phase refrigerant (106) from the refrigerant inlet (110). The liquid distributor (104) includes a main body (160, 162) coupled to a bottom portion (114) of the shell and separating the interior volume (264) of the shell into a distributor volume (222) and a remaining volume (262). The liquid distributor (104) also includes a refrigerant passage (352) formed in the main body (160, 162) and fluidly coupling the distributor volume (222) and the remaining volume (262). The refrigerant passage (352) includes a first portion and second portion, the first portion includes a first cross-sectional area greater than a second cross-sectional area of the second portion, and the first portion is closer to the refrigerant inlet (110) than the second portion.

Abstract: A heating, ventilation, air conditioning, and/or refrigeration (HVAC&R) system (100) includes a refrigerant circuit (104) configured to flow a refrigerant therethrough, a sump (102) configured to direct a lubricant to a compressor (106), an ejector (116) configured to direct the lubricant from the refrigerant circuit (104) to the sump (102), and an expansion device (110) configured to reduce a pressure of the refrigerant directed through the refrigerant circuit (104). The HVAC&R system (100) further includes a controller (130) configured to instruct the expansion device (110) to adjust to a first position to enable the ejector (116) to direct lubricant from the refrigerant circuit (104) to the sump (102) at a first target flow rate in a first mode, and the controller (130) is configured to instruct the expansion device (110) to adjust to a second position to enable the ejector (116) to direct lubricant from the refrigerant circuit (104) to the sump (102) at a second target flow rate in a second mode.

Abstract: The present disclosure relates to a bearing load control system that includes a force application device configured to apply a force to a bearing of a compressor and a sensor configured to provide feedback indicative of an operating parameter of the compressor. The bearing load control system also includes a controller that is communicatively coupled to the sensor and configured to determine an indication of a thrust force applied to the bearing based on the feedback indicative of the operating parameter. The controller is also configured to adjust the force application device to control the force applied to the bearing based at least in part on a control algorithm and the indication of the thrust force.

Abstract: A heating, ventilation, and air conditioning (HVAC) system (10) includes an expansion device (36) disposed between a condenser (34) and an evaporator (38) of a vapor compression system (14) and a control panel (40) communicatively coupled to the expansion device (36). The control panel (40) is configured to: determine a liquid refrigerant level set point of the condenser (34) based on parameters of the vapor compression system (14), provide a first control signal to increase an opening of the expansion device (36) in response determining that the current liquid refrigerant level (82) in the condenser (34) is greater than a determined liquid refrigerant level set point of the condenser (34), and provide a second control signal to decrease the opening of the expansion device (36) in response to determining that the current liquid refrigerant level (82) in the condenser (34) is less than the determined liquid refrigerant level set point of the condenser (34).
