摘要： A district energy system includes at least one energy provisioning unit, an energy management controller; a thermal distribution network coupled to the energy provisioning units and to a plurality of coupling interfaces connectable to the associated HVAC system of buildings within a district, and an electrical distribution network coupled to the energy provisioning units and to the coupling interfaces. The coupling interfaces may include both heat pumps and heat exchangers at each building, to provide heating, cooling and enable harvesting of normally wasted thermal energy from the buildings for re-distribution. The controller can manage the selection and number of energy provisioning units (and their operational set points) coupled to the district thermal distribution network and the electrical distribution network to meet the thermal and electrical demands of the district while satisfying other operational goals such as the minimization of greenhouse gas emissions.

摘要： For controlling energy transfer (Q) of a thermal energy exchanger of an HVAC system, a control system determines flow-dependent model parameters (M) for modelling performance of the thermal energy exchanger, using a plurality of measurement data sets, each measurement data set including for a respective measurement time a value of a measured flow of fluid (Φact), a value of a measured supply temperature (Tsup) of the fluid, and a value of the measured return temperature (Tret) of the fluid. The control system calculates an estimated energy transfer (Qest) of the thermal energy exchanger, using the flow-dependent model parameters (M), and controls (S4) the energy transfer (Q) of the thermal energy exchanger by regulating (S5) the flow of fluid (Φ) through the thermal energy exchanger, using the estimated energy transfer (Qest).

摘要： An air conditioning capacity presenting system presents a capacity of an air conditioning apparatus including at least one outdoor unit, at least one indoor unit, and a connection pipe that connects the outdoor unit and the indoor unit. The air conditioning capacity presenting system includes first acquisition unit, a measurement unit, a second acquisition unit, and a capacity calculating unit. The first acquisition unit acquires outdoor unit capacity information, which is a rated capacity of the outdoor unit or information related to the rated capacity. The measurement unit measures power consumption of the outdoor unit. The second acquisition unit acquires an outside air temperature, which is a temperature of air around the outdoor unit. The capacity calculating unit obtains a calculation value of the capacity of the air conditioning apparatus based on the outdoor unit capacity information, the power consumption, and the outside air temperature.

摘要： A damper system is configured for installation in ductwork including a duct supplying conditioned air through a register boot to a register vent. A damper is movable between a closed position and an open position. A control module includes a control module housing, a controller, a power supply and a transceiver. The controller monitors a remaining energy level of the power supply and transmits a first low battery message via the transceiver when the remaining energy level drops to a first energy threshold. The controller instructs the damper assembly to move to a predetermined position and to transmit a second low battery message via the transceiver when the remaining energy level drops to a second energy threshold.

摘要： A temperature control device (e.g., a thermostat) may be configured to control an internal heat-generating electrical load so as to accurately measure a present temperature in a space around the temperature control device. The temperature control device may comprise a temperature sensing circuit configured to generate a temperature control signal indicating the present temperature in the space, and a control circuit configured to receive the temperature control signal and to control the internal electrical load. The control circuit may be configured to energize the internal electrical load in an awake state and to cause the internal electrical load to consume less power in an idle state. The control circuit may be configured to control the internal electrical load to a first energy level (e.g., a first intensity) during the awake state and to a second energy level (e.g., second intensity) that is less than the first during the idle state.

摘要： Systems and methods for controlling a heat exchanger comprising multiple thermoelectric coolers to provide conditioned air are provided. The method includes receiving system measurements indicative of one or more of the group consisting of: a temperature of a accept-side of a first thermoelectric cooler; a temperature of a reject-side of the first thermoelectric cooler; a temperature of a accept-side of a second thermoelectric cooler; a temperature of a reject-side of the second thermoelectric cooler; an indication of a direction of air flow in the heat exchanger; and an indication of a relative humidity value. The method also includes selectively controlling two or more subsets of thermoelectric coolers in the plurality of thermoelectric coolers based on the received system measurements. This allows for increased efficiency of the heat exchanger.
