Devices, methods, and systems for monitoring a building management system are described herein. One method includes monitoring an attribute of a building, monitoring an activity related to the attribute performed by an operator, and publishing the activity performed by the operator and the attribute of the building.

A thermostat set point estimation method and system that selects a plurality of candidate thermostat set points, determines for each of the plurality of candidate thermostat set points a predicted energy usage amount corresponding to the candidate thermostat set point, determines for each of the plurality of candidate thermostat set points an error value corresponding to the candidate thermostat set point using an actual energy usage amount and the predicted energy usage amount corresponding to the candidate thermostat set point, and identifies an estimated thermostat set point by selecting the candidate thermostat set point having the error value that is lowest from the plurality of candidate thermostat set points.

A modular chiller system includes a switching and pumping module, one or more drycooler modules, and one or more chiller modules. The switching and pumping module, the one or more drycooler modules, and the one or more chiller modules share same water, power, and signal interfaces. The cooling capacity of the modular chiller system may be increased by adding drycooler modules or chiller modules without additional hydraulic and electrical infrastructures.

Method and system are provided for controlling a scalable panel cooling system having multiple cooling panels for cooling heat-generating components housed in a support structure. The method includes: dividing the support structure into areas, each area of the support structure capable of housing a heat-generating component; for each area of the support structure: providing a cooling panel adjacent the area of the support structure; determining whether the area of the support structure is housing an operational heat-generating component; in the case that the area of the support structure is housing an operational heat-generating component, activating the cooling panel adjacent the area of the support structure housing the operational heat-generating component; and in the case that the area of the support structure is not housing a operational heat-generating component, deactivating the cooling panel adjacent the area of the support structure.

There is provided a motor drive comprising: a temperature sensor arranged to sense a temperature of the drive; a braking resistor; switching means arranged when activated to cause current to flow to the braking resistor; and controlling means arranged to activate the switching means when the sensed temperature falls below a predetermined threshold. There is also provided a method of controlling a temperature of a motor drive comprising a braking resistor. The method comprising comprises: monitoring a temperature of the drive; and activating switching means to cause current to flow to the braking resistor when the monitored temperature falls below a predetermined threshold.

A cryogenic refrigerator includes a displacer that is reciprocably mounted within a cylinder; a spool valve that is connected to the compressor and performs switching between an intake mode where a high-pressure refrigerant gas is supplied from the compressor to the cylinder and an exhaust mode where a low-pressure refrigerant gas within the cylinder is made to flow back to the compressor; and a drive unit that drives the spool valve. The spool valve has a valve body, and a drive rod that moves relative to the valve body and is integrated with the spool. The drive unit performs driving so that the magnitude of a speed when the drive rod moves from a top dead center to a bottom dead center is different from the magnitude of a speed when the drive rod moves from the bottom dead center to the top dead center, at the same displacement position.

A modular data center includes: a rack which houses an electronic device; a blower device capable of switching a flowing direction of air and configured to feed the air into the rack; a space housing a moisture absorbent; an in-rack temperature detector which detects a temperature inside the rack; a dew-point temperature detector which detects a dew-point temperature of outside air; and a controller. The controller receives signals inputted from the in-rack temperature detector and the dew-point temperature detector, and controls shutters and the blower device.

A thermal control apparatus and method are disclosed. The method includes: obtaining terminal status information of a terminal, where the terminal status information includes at least a terminal temperature parameter; obtaining environment status information and/or user status information, where the environment status information includes at least an environment temperature parameter and/or an environment humidity parameter, and the user status information includes at least one of a user body temperature parameter, a user electrocardiogram parameter, a user electroencephalogram parameter, or a user skin resistance parameter; and determining and executing a thermal control policy according to the terminal status information and either of or both of the environment status information and the user status information.
