1. A system comprising:
a bypass valve connectable in a bypass path extending between an output side of a compressor and an input side of a heat transfer component to pass compressed refrigerant fluid from the compressor to the heat transfer component; and
a control circuit configured for communication with the bypass valve to open the bypass valve to allow the compressed refrigerant fluid to pass to the heat transfer component thereby increasing the refrigerant fluid provided to the heat transfer component and enabling the speed of the compressor to increase to a level to prevent a reduction in lubrication and/or system efficiency.
 
23. A refrigeration system comprising a controller configured for communication with a bypass valve that is connectable in a bypass path extending between an output side of a compressor and an input side of a heat transfer component to pass compressed refrigerant fluid from the compressor to the heat transfer component, wherein the controller is configured to open the bypass valve to allow the compressed refrigerant fluid to pass to the heat transfer component thereby increasing refrigerant fluid provided to the heat transfer component and enabling the speed of the compressor to increase to a level to prevent a reduction in lubrication and/or system efficiency.
