  • Patent number: 10415855
    Abstract: A refrigeration cycle apparatus includes an evaporator, a first compressor, an intercooler, a second compressor, a condenser, and a refrigerant liquid supply passage. The intercooler stores refrigerant liquid and also cools refrigerant vapor compressed by the first compressor and expels it. The second compressor sucks in the refrigerant vapor expelled from the intercooler and compresses it. The intercooler includes a container, an intercooling passage, and a pump. The container contains a vapor space and stores refrigerant liquid. The intercooling passage is a passage in which a part of the refrigerant liquid stored in the container flows and that supplies the part of the refrigerant liquid to the vapor space. The pump pumps a part of the refrigerant liquid stored in the container to the vapor space.

  • 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.
