摘要： A method of measuring the amount of energy consumed from a water heater having a tank with two or more temperature sensors located a predetermined heights on or in the tank, the method including the step of; for each sensor, determining a corresponding volume of a segment of the tank, measuring the change of temperature at each temperature sensor, calculating the energy for the corresponding volume for each sensor, and summing the energy changes for all the sensors to determine the amount of energy consumed. The energy usage can be recorded with chronological information to construct a usage pattern which can be used for controlling the heater and for providing the user with details of energy usage. The system does not require the use of data derived from a flow meter.

摘要： A thermostat includes a plurality of HVAC (heating, ventilation, and air conditioning) wire connectors including a connection to at least one call relay wire. The thermostat may also include a powering circuit, including a rechargeable battery, which is configured to provide electrical power to the thermostat by power stealing from a selected call relay wire. The power stealing may comprise an active power stealing mode, in which power is taken from the same selected call relay wire that is used to call for an HVAC function, and an inactive power stealing mode in which, in which no active call is being made. The powering circuit may be configured to substantially suspend (or at least reduce the level of) power stealing for at least a first time period following each transition of the thermostat from between operating states.

摘要： A demand based control for a hydronic heating system varies the heat response based on an actual demand of the conditioned space, rather than an estimated thermal loss. Differences between supply and return of a heat transfer medium, such as forced hot water, are measured for the conditioned space, as well as the flow rate of the forced water to determine an actual thermal transfer to the conditioned space. A required heat generation is computed based on the measured transfer and resultant temperature change of the conditioned space, and heat generation parameters such as boiler firing rate and circulator pump speed varied to control the heat transfer to the conditioned space and avoid overshoot or excessive heat generation beyond that needed for the measured demand.

摘要： This invention teaches a method of controlling the heating system of a commercial building, to reduce the thermal energy consumed by use of thermal parameters which are derived from readily-available data both internal and external to the building. By deriving a statistical relationship for each of the Solar Gain Rate and Day-time Natural Cool-down Rate from observed data, then based on the weather forecast, it is possible to determine if, when and for how long the mechanical heating system can be turned off or disabled from supplying heat to some of all of the building in question.

摘要： A method is provided for adjusting several parallel connected heat exchangers supplied with a coolant medium. The aim of the invention is to simplify the adjustment. For this purpose, the method consists in a) determining a specific value of heat requirement for each heat exchanger in a predetermined time period; b) comparing the specific values of all heat exchangers therebetween and c) in modifying the adjustment of the heat exchanger having the lowest specific value of heat requirement in such a way that the heat requirement thereof is increased.

摘要： The invention provides an improved method for determining the natural thermal lag (NTL) of a building, where the improvement includes using the 15 minute interval energy usage data for the building, and data the external temperature to determine the NTL. This improved method has the advantage of being independent of any need to acquire data regarding internal temperature of the building in question.
