Abstract: Embodiments of apparatus, transport refrigeration units, and methods for operating the same can control cooling capacity for a refrigerant vapor compression system. Embodiments can provide use discharge pressure control for modulating cooling capacity for a refrigerant vapor compression system. In one embodiment, discharge pressure control can reduce the cooling capacity without increasing the compressor pressure ratio or discharge temperature. In one embodiment, discharge pressure control can reduce the cooling capacity independently of system superheat. In one embodiment, discharge pressure control can control a compressor discharge temperature; for example, to remain below a threshold temperature.

Abstract: An activation indicator for a refrigeration system pressure relief valve is presented. In one embodiment, the indicator comprises a covering that covers an outlet passage of the pressure relief valve. The covering is at least partially displaceable by refrigerant as it exits the refrigeration system through the pressure relief valve. In another embodiment, sensors outputting a signal transmit an altered signal when the relief device releases refrigerant. A notification device is activated to indicate that the pressure relief device has activated.
