Abstract: A refrigeration system or heat pump is provided that includes: a compressor, a condenser, a liquid line, an expansion device, an evaporator, and a suction line to the compressor. A power converter or module supplies electrical power. A first thermal coupling is formed between a first portion of a heat pipe and the power converter module. A second thermal coupling is formed between a second portion of the heat pipe and a component of the refrigeration system or heat pump. The heat pipe receives heat from the power converter or module at the first portion, transfer the heat from the first portion to the second portion and transfer the heat from the second portion to the component of the refrigeration system or heat pump so as to cool the power converter or module.

Abstract: There is disclosed an electrical connection unit for a refrigeration system comprising: a container defining an interior for containing electrical circuitry, the container having an external port configured to couple with an external connector; a closure moveable relative to the container between a closed configuration in which access to the interior is prevented, and an open configuration in which access to the interior is permitted. The closure has a locking portion defining a connector opening for receiving the connector, configured so that movement of the closure to the open configuration is prevented by interlocking engagement of the connector and the closure. There is also disclosed an associated method of coupling or decoupling a connector and an electrical connection unit.

Abstract: Methods and systems for reconfigurable utility power with passive voltage booster for a transport climate control system are provided. The transport climate control system includes a passive boost circuit. The system also includes a controller configured to determine whether the passive boost circuit is connected to one of a first utility power and a second utility power. The controller instructs the passive boost circuit to operate in a first configuration when the passive boost circuit is connected to the first utility power and instructs the passive boost circuit to operate in a second configuration when the passive boost circuit is connected to the second utility power. The system further includes a load such as a motor. The load can drive a device such as a compressor, a fan, etc. The load is connected to the passive boost circuit and configured to receive power from the passive boost circuit.
