TL;DR
A low ambient kit is an accessory package that lets an air conditioner or heat pump run in cooling mode when outdoor temperatures drop below its standard operating floor, typically under 55 degrees F. Components such as a condenser fan speed control, crankcase heater, and freeze protection keep head pressure high enough for the metering device to work.
