Abstract:
Systems and methods are provided for controlling a setback mode of a power-consuming device, and for controlling setback recovery of power-consuming devices, in order to make setback and setback recovery more dynamic based on current environmental parameters and previous observed operating parameters, in order to enable more efficient operation of power-consuming devices resulting in reduced energy costs and increased power efficiency.
Abstract:
A sensor surrogate (120) for causing a heating, ventilating, and air conditioning (HVAC) system (1 10) to maintain a desired room temperature, contains a temperature sensor (122) for determining an actual room temperature and logic embodied on at least one non-transitory computer readable medium (130). The logic (130) is configured to perform the steps of: calculating a current low temperature that is lower than a pre-programmed HVAC system temperature and providing the HVAC system with a first signal that represents the calculated current low temperature, if the desired temperature is above the pre-programmed HVAC system temperature; and calculating a current high temperature that is above the pre-programmed HVAC system temperature and providing the HVAC system (110) with a second signal that represents the calculated current high temperature, if the desired room temperature is below the pre-programmed HVAC system temperature.
Abstract:
The current application is directed to an intelligent-thermostat-controlled environmental-conditioning system in which computational tasks and subcomponents with associated intelligent-thermostat functionalities are distributed to one or more of concealed and visible portions of one or more intelligent thermostats and, in certain implementations, to one or more intermediate boxes. The intelligent thermostats are interconnected to intermediate boxes by wired and/or wireless interfaces and intelligent thermostats intercommunicate with one another by wireless communications. Wireless communications include communications through a local router and an ISP, 3G and 4G wireless communications through a mobile service provider. Components of the intelligent- thermostat-controlled environmental-conditioning system may also be connected by wireless communications to remote computing facilities.
Abstract:
A thermostat and related methods is described for controlling an HVAC system having one or two separate transformers for supplying power to the HVAC system. The thermostat includes isolation circuitry housed within the thermostat to safely connect to the HVAC control wires and power wire(s) whether the HVAC system has one or two separate transformers without the use of removable jumpers or manual rewiring. The thermostat can include a processor that sends DC signals for turning on and turning off each of the HVAC functions, and an isolator adapted to electrically isolate the processor from the control wires and power wire(s). The circuitry can include one or more field effect transistors adapted and arranged so as to open or close an electrical connections between the control and power wires, thereby turning on or off the associated HVAC function.
Abstract:
An air-conditioner and a method for controlling the same are disclosed. The air-conditioner installs a memory slot into a display unit of the air-conditioner to facilitate Input/Output operations of data, and allows a user to easily recognize a memory card inserted into the memory slot. At least one of different memory cards can be inserted into the memory card slot, such that a variety of memory cards for use in a variety of household appliances can be applied to the air- conditioner. If the memory card is inserted into the memory slot, data of the memory card is displayed such that the user can immediately recognize the data of the memory card, resulting in greater convenience of the user.
Abstract:
Capabilities of a chiller water plant (106) are modeled using operational data, equipment data, and system configuration data enabling changes to be made to the configuration data and report the resulting changes in performance of the model.
