    摘要： A heating, ventilation, and air conditioning (HVAC) system includes a working fluid reservoir having an enclosure defining a chamber configured to fluidly couple to a working fluid circuit, where the chamber is configured to receive and store working fluid from the working fluid circuit. The HVAC system also includes an actuator configured to adjust a component disposed within the enclosure to adjust a volume of the chamber and a control system configured to instruct the actuator to adjust a position of the component disposed within the enclosure to increase the volume of the chamber, to reduce the volume of the chamber, or both based on an operating mode of the HVAC system.

    摘要： A remote monitoring method, performed at a central location by a controller associated with the central location, for use with multiple remotely located boats is described involving determining, based upon first location information, second location information and tide information, whether a water-fed air conditioner of a first boat or a water-fed air conditioner of a second boat should be shut off or turned back on due to tide-caused depth changes at a first location or second location. A controller for a boat has at least one processor; and programming which, when executed will cause the at least one processor to, when the boat's air conditioner is operating, cause at least a water pump pumping water to the condenser to shut off at a time, based upon a depth at the current location of the boat of less than a specified minimum acceptable depth.

    摘要： A chiller system includes: a chiller; a load; a feed pipe through which water flows from the chiller to the load; a return pipe through which water flows to the chiller from the load; a first controller configured to control the chiller; and a second controller configured to output a chiller operating command to the first controller, the chiller including a first sensor configured to measure an inlet water temperature of the water flowing through the return pipe to the chiller, a second sensor configured to measure an outlet water temperature of the water flowing through the feed pipe from the chiller, and a third sensor configured to measure an outside air temperature at a chiller installation location, and the first controller calculates a temperature range operational for the chiller based on an inlet water temperature, an outlet water temperature, and an outside air temperature, and then outputs information on the calculated temperature range to the second controller.

    摘要： A relay includes a first relay unit and a second relay unit provided between an outdoor unit and an indoor unit to allow refrigerant to circulate between the first relay unit and the outdoor unit and between the second relay unit and the outdoor unit, and a heat medium circuit connecting the first relay unit and the second relay unit to the indoor unit to allow a heat medium to circulate through the heat medium circuit. The second relay unit is installed above or on a top of the first relay unit.

    摘要： An HVAC system includes a plurality of heat transfer devices operable to transfer heat into or out of the plurality zones. The HVAC system includes a controller configured to obtain a heat map indicating zone temperatures, use a thermal model of the building space to predict the zone temperatures as a function of control decisions indicating an amount of heat to transfer into or out of each of the plurality of zones by the plurality of heat transfer devices, determine the amount of heat to transfer into or out of each of the plurality of zones subject to a constraint or penalty based on differences between the zone temperatures predicted to result from the control decisions, and operate the heat transfer devices to transfer the amount of heat into or out of each of the plurality of zones in accordance with the control decisions.

    摘要： Various embodiments include a method of controlling heat exchange via a terminal unit of a terminal-side circuit of a system for HVAC with a source-side circuit coupled to the terminal-side circuit comprising: reading a terminal-side supply temperature signal; producing a supply temperature from the terminal-side supply temperature signal; estimating a percentage demand signal as a function of the supply temperature; estimating an actual demand for power by rescaling a value of maximum available power by the percentage demand signal; comparing the actual demand for power to the value of maximum available power; and if the actual demand for power exceeds the value of maximum available power: producing a first flow control signal based on the value of maximum available power; and controlling a flow of a fluid through the source-side circuit based on the first flow control signal.
