A method of shutting down a refrigeration system including: initiating a shutdown process of the refrigeration system; closing a first valve within a refrigerant circuit of the refrigeration system; operating a compressor within the refrigerant circuit; detecting a suction pressure within the refrigerant circuit; closing a second valve within the refrigerant circuit of the refrigeration system when the suction pressure is below a threshold suction pressure; and stopping operation of the compressor.

Refrigerant system operation sequences for leak prevention

A transportation refrigeration system and a CAN ID allocation method for a transportation refrigeration system. The transportation refrigeration system includes: a refrigeration circuit including a compressor, a condenser, and a plurality of evaporators connected in parallel, all of which are connected to form a loop; a plurality of chambers, each of the evaporators being located in one of the chambers to adjust the chamber; a plurality of sensors of the same type, each of the sensors being installed in one of the chambers respectively; and a control unit, after being installed in place and energized, the plurality of sensors send their own identification codes to the control unit, and the control unit allocates a CAN ID to each of the sensors after receiving the identification codes of the sensors, so that the identification code of each sensor is bound to the corresponding CAN ID respectively.

Transport refrigeration system and a CAN ID distributing method for the transport refrigeration system

A method of mitigating refrigerant leaks within a refrigeration system that includes: detecting a leak of a refrigerant from a refrigeration system; closing a first valve to inhibit a fluid flow of the refrigerant between an evaporator and a condenser fluidly connected to the evaporator; and operating a compressor to direct another fluid flow of the refrigerant from the evaporator to the compressor.
