  • Patent number: 10315495
    Abstract: A system including mode and battery modules. The mode module, based on parameters, determines whether to operate in a shore power, engine or battery mode. One or more batteries are charged based on received utility power while in the shore power mode. The batteries, while in the engine mode, are charged based on power received from a power source. The battery module, while operating in the battery mode, determines a speed based on a temperature within a temperature controlled container of a vehicle and a state of charge of the batteries. The compressor is run at the speed while in the battery mode. While in the battery mode, the batteries are not being charged based on power from a shore power source and the power source from which power is received during the engine mode.

  • Patent number: 10309405
    Abstract: A circulator blower controller for a circulator blower of a heating, ventilation, and air conditioning (HVAC) system of a building includes an interface configured to receive a demand signal with an operating mode from a thermostat. A switching circuit selectively connects power to a tap of a motor of the circulator blower. A data store configured to store a mapping from a speed to the tap. For each tap, a processor observes power consumed by the circulator blower while power is connected to the tap by the switching circuit. The processor determines the mapping by sorting the taps based on observed power consumption. The processor selects a first speed based on the demand signal from the thermostat. The processor identifies a first tap from the mapping based on the first speed and generates the tap selection signal to control the switching circuit to connect power to the first tap.

  • Patent number: 10302363
    Abstract: In one embodiment, a cooling system includes a thermosyphon cooler that cools a cooling fluid through dry cooling and a cooling tower that cools a cooling fluid through evaporative cooling. The thermosyphon cooler uses natural convection to circulate a refrigerant between a shell and tube evaporator and an air cooled condenser. The thermosyphon cooler is located in the cooling system upstream of, and in series with, the cooling tower, and is operated when the thermosyphon cooler is more economically and/or resource efficient to operate than the cooling tower. According to certain embodiments, factors, such as the ambient temperature, the cost of electricity, and the cost of water, among others, are used to determine whether to operate the thermosyphon cooler, the cooling tower, or both.
