  • Patent number: 10545517
    Abstract: In controlling the HVAC system, a need to determine an expected indoor temperature profile for a particular schedule of setpoint temperatures may arise. To make such a determination, a thermodynamic model of the structure is used. The thermodynamic model is generated by fitting weighting factors of a set of basis functions to a variety of historical data including time information, temperature information, and HVAC actuation state information. The set of basis functions characterize an indoor temperature trajectory of the structure in response to a change in HVAC actuation state, and include an inertial carryover component that characterizes a carryover of a rate of indoor temperature change that was occurring immediately prior to the change in actuation state.

  • Patent number: 10527371
    Abstract: An anomaly monitoring device is installed in an integrated gasification combined cycle plant that experiences varying loads, and the device monitors a heat exchanger that performs heat exchange between a carbon-containing fuel and a heat exchange medium flowing through a heat transfer tube. For each load on the integrated gasification combined cycle plant, the anomaly monitoring device calculates the average value and the standard deviation of a state quantity of the heat exchanger, calculates the Mahalanobis distance on the basis of the average value and the standard deviation, and from the calculated Mahalanobis distance determines the presence or absence of an anomaly of the heat transfer surface of the heat transfer tube.

  • Patent number: 10502117
    Abstract: A heat storage system has a heat source that generates heat and releases the heat to a first heat medium and a heat storage body that stores heat. The heat storage body changes to a first phase in a solid state when a temperature of the heat storage body is lower than or equal to a phase transition temperature, and changes to a second phase in a solid state when a temperature of the heat storage body exceeds the phase transition temperature. The heat storage body stores or releases heat due to a phase transition between the first phase and the second phase. A mode of operation of the heat storage body is switchable between a heat storage mode in which the heat storage body stores heat of the first heat medium and a heat release mode in which the heat storage body releases the heat stored in the heat storage body to a heat transfer target.

  • Patent number: 10495364
    Abstract: A method controls a vapor compression system including a variable speed compressor. A desired discharge temperature of the compressor is determined using a mapping between values of the discharge temperature of the compressor and values of speed of the compressor and outdoor air temperature. A transition function for transitioning a current discharge temperature to the desired discharge temperature is determined, such that the transition function is continuous and a rate of change of the transition function is limited. Next, a valve of the vapor compression system is controlled such that the discharge temperature is transitioned to the desired discharge temperature based on the transition function.
