  • Patent number: 10488072
    Abstract: An air conditioning system has an air conditioner, which includes an outdoor unit and an indoor unit that configure a refrigerant circuit, and a controller, which controls the running of the air conditioner. The controller does not allow operation of the air conditioner to start in a case where a signal from a ventilation unit that includes a ventilation fan for ventilation and ventilates a target space or a refrigerant leak sensor that detects refrigerant leakage in the target space is not input to the controller. Because of this, even in a configuration where an air conditioner and a ventilation unit are installed independently of each other, operation of the air conditioner can be performed in a state in which there is reliably established a countermeasure such as the ventilation unit being operated when the refrigerant has leaked, and safety and security with respect to refrigerant leakage are reliably ensured.

  • Patent number: 10295974
    Abstract: Systems and methods are described for interactively and graphically displaying performance information to a user of an HVAC system controlled by a self-programming network-connected thermostat. The information is made on a remote display device such as a smartphone, tablet computer or other computer, and includes a graphical daily summary each of several days. In response to a user selection of a day, detailed performance information is graphically displayed that can include an indication of HVAC activity on a timeline, the number of hours of HVAC activity, as well as one or more symbols on a timeline indicating setpoint changes, and when a setpoint was changed due to non-occupancy.

  • Patent number: 10288309
    Abstract: Methods, devices, and computer readable medium are described for receiving from a thermostat device at a server device climate system usage information and settings and sending from the server device ecorank information, wherein the ecorank information is derived from a comparison of usage of climate systems controlled by the thermostat device in comparison to a comparison group, the comparison group comprising other climate systems controlled by other thermostat devices. The comparison group is determined based on profile information describing the dwelling, dwelling size, dwelling location, dwelling occupants, climate system technology, and related information. In some embodiments, the ecorank information may be one or more of a numerical score, percentage, graphic, icon, color, letter, and an audio item. In some embodiments, the energy consumed by the climate systems may be reported by an associated energy measurement device or estimated by heating and cooling usage hours.
