摘要： An air conditioning system suppresses energy consumption by efficient shared use of air in a common space that is not subjected to air conditioning in an indoor area, among a plurality of air conditioners for the purpose of heat exchange. A plurality of air conditioners each include: a usage-side heat exchanger configured to carry out heat exchange with air in an air-conditioning target space; a heat source-side heat exchanger configured to carry out heat transfer to and from the usage-side heat exchanger; and a heat source-side fan configured to feed air from a common space to the heat source-side heat exchanger and to blow the air into the common space. The heat source-side heat exchangers of the air conditioners are disposed in the common space. A first ventilation fan whose airflow volume is changeable is disposed near an exhaust port through which air is discharged from the common space toward an outdoor area. A controller changes the airflow volume of the ventilation fan, based on information on an air temperature of the common space.

摘要： A cooling system is designed to generally allow for one or more compressors to be bypassed when ambient temperatures are low. The system includes a bypass line and valve that opens when ambient temperatures are low and/or when the pressure of the refrigerant in the system is low. In this manner, the refrigerant can flow through the bypass line instead of through one or more compressors. These compressors may then be shut off. To supply any needed pressure to cycle the refrigerant, the system may include a pump that turns on when the bypass line is open. When ambient temperatures are extremely low, thermosiphon may be used to cycle the refrigerant.

摘要： A method of and system for conserving power of a battery in a battery-powered electronic device capable of wireless communications are disclosed. The electronic device, which can be a digital video camera or other component of a monitoring system or an HVAC controller, an appliance, or another aspect of a smart home system, is wirelessly communicable with one or more hubs over a wireless local area network. The electronic device has at least a high power radio and a low power radio operating at different frequencies. Communications switch from the high power radio to the low power radio upon the occurrence of a trigger event such as battery charge dropping below a designated threshold. The electronic device may be part of a WLAN coupled to a WAN via the Internet and a cellular network.

摘要： A demand response system includes a mobile application of a mobile device that is configured to initiate altering an operating condition of a network device disposed at a site using location based services. A demand response application interface module is configured to enable access between a utility company and the network device to communicate energy management information therebetween. The network device is configured to be remotely altered by each of the demand response application interface module and the mobile application separately based on the location based services and the energy management information. A method of managing a demand response system includes detecting a user being disposed away from a site, detecting energy management information from a utility company associated with the site, and initiating a reduction in energy use at the site in response to the relative location of the user and the energy management information.

摘要： Methods for controlling temperature in a conditioned enclosure such as a dwelling are described that include an “auto-away” and/or “auto-arrival” feature for detecting unexpected absences which provide opportunities for significant energy savings through automatic adjustment of the setpoint temperature. According to some preferred embodiments, when no occupancy has been detected for a minimum time interval, an “auto-away” feature triggers a changes of the state of the enclosure, and the actual operating setpoint temperature is changed to a predetermined energy-saving away-state temperature, regardless of the setpoint temperature indicated by the normal thermostat schedule. The purpose of the “auto away” feature is to avoid unnecessary heating or cooling when there are no occupants present to actually experience or enjoy the comfort settings of the schedule, thereby saving energy.
