Abstract: A cooling system configured to remove heat from a chimney of a server cabinet. The cooling system including a first chimney portion adjacent to the server cabinet, a second chimney portion extending from a top of the first chimney portion, wherein the second chimney portion is disposed above the server cabinet, a chimney heat exchanger disposed in the second chimney portion and above the server cabinet, a fluid inlet for providing a working fluid to the chimney heat exchanger, a fluid outlet for discharging the working fluid from the chimney heat exchanger, and an air handler heat exchanger connected to the chimney heat exchanger by a return air plenum, wherein the chimney heat exchanger has an upstream surface that receives waste heat generated by a server disposed in the server cabinet and a downstream surface that discharges air to the return air plenum.

Abstract: A heat exchanger for removing heat from a server cabinet, wherein the heat exchanger is disposed within the server cabinet and behind at least one server in the server cabinet, the heat exchanger including an upstream surface facing the at least one server, the upstream surface receiving air heated by the at least one server, wherein the air enters the heat exchanger in a generally horizontal direction, the heat exchanger having a fluid inlet for receiving a working fluid, and a fluid outlet for discharging the working fluid, wherein the working fluid cools the air entering the heat exchanger, and the heat exchanger having a downstream surface that discharges air cooled by the heat exchanger, wherein the air cooled by the heat exchanger exits the heat exchanger in a generally vertical direction.

Abstract: A cooling system configured to remove heat from a chimney of a server cabinet. The chimney has an extending portion extending above the server rack including a chimney heat exchanger in the extending portion above the server rack. The chimney heat exchanger has a fluid inlet for receiving a working fluid and a fluid outlet for discharging the working fluid. The chimney heat exchanger also has an upstream surface receiving warm waste heat generated by one or more servers and a downstream surface that discharges cooled air cooled by the chimney heat exchanger. The server rack may be accessed through the chimney without requiring movement of the chimney heat exchanger.

Abstract: A workstation cooling system includes a radiant panel configured to be disposed in a workstation. The workstation cooling system also includes a water supply conduit configured to provide a cooling water flow to an inlet of the radiant panel and a water return conduit configured to receive the cooling water flow from an outlet of the radiant panel. The workstation cooling system additionally includes a control valve configured to receive control signals to adjust the cooling water flow provided to the radiant panel to enable the radiant panel to absorb heat to maintain a target temperature of the workstation.

Abstract: A cooling system configured to remove heat from a chimney of a server cabinet. The system includes a first heat exchanger unit in the chimney of the server cabinet. The first heat exchanger has a fluid inlet for receiving a working fluid and a fluid outlet for discharging the working fluid. The first heat exchanger also has an upstream surface receiving waste heat generated by one or more servers and a downstream surface that discharges air cooled by the first heat exchanger. The upstream surface is generally perpendicular to the downstream surface.

Abstract: A sensor-based ventilation system includes a sensor, a ventilation device, and a controller. The controller receives a first indication from the sensor related to toilet usage or a humidity level within a room. The controller also sends a first instruction to actuate the ventilation device to initiate or increase ventilation of the room based on the first indication. The controller further receives a second indication from the sensor related to the toilet usage or the humidity level within the room changing after sending the first instruction. controller sends a second instruction to actuate the ventilation device to stop or reduce ventilation of the room based on the second indication.
