A processing water supply system for supplying processing water to a processing apparatus includes a first heat exchanger that cools the processing water by heat of vaporization of a cooling medium, a second heat exchanger that cools the cooling medium compressed to reach a high temperature, a cooling water receiving route that receives the cooling water from cooling water supply equipment to the second heat exchanger, a cooling water drain route that drains the cooling water heat-exchanged by the second heat exchanger to reach a high temperature to drain equipment, and a bypass route that is disposed between the cooling water receiving route and the cooling water drain route and adjusts the cooling water reaching the high temperature at the second heat exchanger to a temperature permissible by the drain equipment.

An air flow controller for an air cleaner and an air cleaner are provided. The air flow controller may include a fan, and a housing, the fan being provided in the housing and the housing being movable from an initial horizontal position in which the air flow controller directs air flow in a vertical direction to an inclined position in which the air flow controller directs air flow in a diagonal direction.

One aspect of the invention provides a system including: at least one temperature-regulation element configured for fluidic communication with a fluid repository; and a processor in electronic communication with the at least one temperature-regulation element. The processor is configured to: determine a temperature threshold value for a volume of fluid contained by the fluid repository; calculate an amount of solar radiation to which the volume of fluid is exposed; calculate, from the amount of solar radiation and a set of temperature-regulation factors, a time period for reaching the temperature threshold value for the volume of fluid, wherein the set of temperature-regulation factors comprises at least a current temperature of the fluid volume and an energy-transfer rate for the temperature-regulation element; identify a desired use time for the volume of fluid; and activate the at least one temperature-regulation element according to the time period and the desired use time.

A method is described. The method includes monitoring a combined workload of electronic devices that are being cooled by a secondary loop. The method includes flowing a first portion of secondary fluid through the secondary loop's heat exchanger and bypassing a second portion of the secondary fluid through the secondary loop's heat exchanger. The method includes, in response to an increase in the combined workload of the electronic devices, adjusting a first setting of a valve to increase the first portion and decrease the second portion. The method includes, in response to a decrease in the combined workload of the electronic devices, adjusting a second setting of the valve to decrease the first portion and increase the second portion.

A space controller includes a housing, a sensor, a communications interface, a camera lens, a camera, a display, and a processing circuit. The sensor and the communications interface are coupled to the housing. The sensor is configured to generate sensor data that is indicative of a condition of an environment surrounding the housing. The communications interface is configured to communicate with a controlled device. The camera and the processing circuit are positioned within the housing. In particular, the camera is aligned with the camera lens. The display is configured to display images received from the camera and to receive user input. The processing circuit is configured to identify the environmental condition based on the sensor data and to operate the controlled device based on the environmental condition and the user input.

A control valve includes a casing, a valve body, seal tube members, a fuel passage, and a thermostat. The casing has an inflow port and a plurality of outflow ports. The valve body is rotatably disposed inside the casing, and valve holes are formed in a circumferential wall portion. The seal tube members communicate with the outflow ports, abut an outer circumferential surface of the circumferential wall portion, and are opened and closed by corresponding valve holes. Thermostat opens and closes the fuel passage in response to a detected temperature. A communication groove is formed on an inner circumferential surface of the casing. The communication groove causes the inflow port and an upstream portion of the fuel passage to communicate with each other by partially expanding a gap between the circumferential wall portion and the casing.
