摘要:
A fault-tolerant HVAC system capable of continued operation in the event of a thermostat malfunction. An HVAC controller controls the operation of an HVAC unit in accordance with a temperature signal output from the thermostat and indicative of air temperature of a conditioned space proximate the thermostat. The HVAC controller detects a thermostat malfunction and, in response thereto, instead controls the operation of the HVAC unit in accordance with a temperature sensor outputting a signal indicative of return air temperature from the conditioned space.
摘要:
A method for bringing an appliance and/or an electrical or mechanical system of a residence into communication with another, or with a control device within the residence, or with an other communication source outside the residence, so as to establish a home automation system, or enlarge upon an existing automation system. An appliance interface module apparatus is also provided for facilitating communication between an appliance, and the automation system as a whole. The appliance interface module may be capable of controlling, upon command, the specific detailed operations of the appliance to which it is attached, and may, upon inquiry, transmit data which has been recorded, stored and/or calculated by the module.
摘要:
A multi-unit automated space management and communication system for use in association with a structure having a plurality of units. The system includes circuitry that monitors various utility related aspects of each of the plurality of units. The system further includes an automated subsystem disposed in each one of the plurality of units. This subsystem includes at least one appliance, at least one communication medium means, at least one interface means for connecting the at least one appliance apparatus into a signal exchanging relationship with the at least one communication medium means, at least one communication source, operably connected to the at least one communication medium means. The system further includes an external communication interface linking the automated subsystem to the monitoring means in a signal-exchanging relationship. The system still further includes data storage circuits.
摘要:
A method and apparatus for controlling the circulation of heat transfer fluid for thermal conditioning systems for spaces, in which the temperatures of several at least partially thermally separate spaces are monitored and averaged, and compared with a predetermined set point temperature, for purposes of controlling the operation of a source of thermal conditioning. In addition, the temperature differentials between the several spaces are also monitored, for purposes of controlling the circulation of the heat transfer fluid. The present invention permits the continued circulation of the heat transfer fluid, even if no heating or cooling is required, for purposes of reducing the temperature differentials between the several spaces.
摘要:
An apparatus and method for preparing an indoor environmental conditioning system for spaces, for operation. The apparatus and method are advantageously configured for use with an indoor environmental conditioning system in which the spaces are provided with an indoor environmental conditioning input and an indoor environmental conditioning sensor, both operably connected to an indoor environmental conditioning source. Each space is further provided with means for actuating the indoor environmental conditioning source. The apparatus and method enable the indoor environmental conditioning system to be placed in an initial condition such that no space can receive, and no sensor report, indoor environmental conditioning. The indoor environmental conditioning inputs are actuated one at a time, and operably linked thereafter with the indoor environmental conditioning sensor which reports a change in environmental conditioning status.
摘要:
A control system for a fluid-fuel burner, such as a furnace for an HVAC system. The furnace has a variable flow of fuel into the burner. In addition, the circulating air blower is also variable. The furnace heat exchanger plenum is maintained at a substantially constant temperature, as a means for providing substantially constant temperature air to the spaces to be heated.
摘要:
A system for operating a plurality of motors with a single controller is disclosed. This system includes a first motor, a second motor that is matched to the first motor but has a lower power rating than the first motor and a controller electrically driving the first and second motors with a modulated voltage at one frequency selected from one or more frequencies over a complete range of frequencies. The controller generates a frequency of the modulated voltage from the range of frequencies which is proportional to the desired speed for the first and second motors. A method for building such a system is also disclosed. This system and method have particular application to HVAC systems.
摘要:
A fault-tolerant HVAC system for use in a single or multi-zoned system, capable of continued operation in the event of a thermostat, or other sensing device malfunction. An HVAC controller controls the operation of an HVAC unit in accordance with a temperature signal output from the thermostat and indicative of air temperature of a conditioned space proximate the thermostat. The HVAC controller detects a thermostat malfunction and, in response thereto, instead controls the operation of the HVAC unit in accordance with a temperature sensor outputting a signal indicative of return air temperature from the conditioned space.
摘要:
An indoor environmental conditioning system and a method for controlling the circulation of non-conditioned air. The system comprises a conditioning source, air distribution source and air distribution conduit. The air may be propelled at at least two different flow rates.
