  • Patent number: 9971325
    Abstract: A method for controlling the readiness of an appliance in a system having a mobile device capable of determining its current location, storing a previous location and storing a home location for a delivery point of the appliance, and determining a location change event by comparing the current to previous location to result in a difference. If the mobile device is determined to be close to the home location and the difference magnitude is greater than a threshold, a first distance corresponding to the distance between the current and home location and a second distance corresponding to the distance between the previous and home location are computed. If the first distance is smaller than the second distance, the readiness of the appliance is enhanced. Otherwise, the readiness of the appliance is relaxed.

  • Publication number: 20170234550
    Abstract: A combined hot water and air heating and conditioning system including a first heat exchanger, a heat pump, a chilling tower loop, a burner and a second heat exchanger to provide hot water, air heating and air cooling. The system provides hot water, air heating and cooling all in one single unit. The system utilizes a heat pump to remove heat from ambient air and transfer the rejected heat into a hot water system, thereby using waste heat to heat the hot water system. The system utilizes a heat exchanger not only for the purpose of transferring heat from a heating source to a fluid in the heat exchanger but also for the purpose of dissipating heat from the fluid in the heat exchanger to the surroundings of the heat exchanger, thereby allowing a heat pump to act both as an air heating and conditioning device.
