摘要： An energy-reducing method and apparatus for retrofitting a single zone, constant volume HVAC system, with or without an economizer, that provides heating, cooling, and ventilation to occupants within a building space. The present invention includes the introduction of a programmable logic controller and variable frequency drive (VFD) that takes control of the existing fan, heating, cooling, and optional economizer operation. The reduction of the fan speed in the ventilation mode when the 100% operation is not needed saves significant energy of the existing constant volume HVAC system where the fan motor is designed to run 100% of the time.

摘要： Various arrangements for detecting and mitigating toxic gases are presented. Components of a home automation system may be used to monitor gas concentrations in home. Changes or elevated levels of gas concentrations may trigger mitigation or diagnosis procedures. Diagnosis procedures may include correlating the gas sensor readings with the activity of components of a home to identify possible causality. The activity of components may be changed and altered to test correlations or determine causality between components.

摘要： A method for fan speed control for a condenser fan in an air conditioning system includes determining a refrigerant condition at an inlet of a compressor by a condenser fan speed control module; determining a refrigerant condition at an outlet of the compressor by the condenser fan speed control module; determining a parabolic curve of a relationship between an air conditioning system performance metric and a speed of the condenser fan based on the determined inlet condition and the determined outlet condition by the condenser fan speed control module; identifying an optimum condenser fan speed based on a vertex of the parabolic curve by the condenser fan speed control module; and controlling the speed of the condenser fan to meet the optimum fan speed by the condenser fan speed control module.

摘要： An Environmental Control System includes a sensor, an air purification subsystem, and a controller in communication with the sensor and air purification subsystem. The sensor detects a contaminant in the air and generates a contaminant signal. The controller compares the contaminant signal to a predicted sensory response threshold. When the contaminant signal reaches the predicted sensory response threshold, the controller commands the air purification subsystem to alter a condition in the air.

摘要： An HVAC controller and/or server may be programmed to determine if ventilation of a building is desired based, at least in part, on the one or more user-specified air quality thresholds stored in a memory, and one or more of a measure of indoor air quality and a measure of outdoor air quality. The air quality parameter threshold may relate to an air quality index, an air pollutant concentration, a smog alert, a pollen count, a dew point, a chance of precipitation, and/or the like. In addition, the HVAC controller and/or server may take into account current or future weather conditions when determining the ventilation needs of a building. Upon determining that ventilation is needed or recommended, the HVAC controller may send or display a message to the user. The message may recommendation that the user open a window or operate a ventilation system, as desired.

摘要： A ventilation system for an air conditioning system includes dampers, a heat exchange unit, and a control unit. One damper controls the flow of ambient air into the system. The other damper controls the flow of relief/exhaust air that is cannibalized from return air from a room or space being cooled (or heated) by the air conditioning system. The ventilation system utilizes a control algorithm in the control unit to calculate, at stepped spaced apart increasing room ventilation rates, increasing CO2 concentrations in the air in the room that are below a maximum desired CO2 concentration in a room. The control algorithm permits a control unit in the ventilation system to open and close the dampers to maintain a CO2 concentration in the room that is below the desired CO2 concentration level.
