A transport refrigeration system having a compressor, condenser, receiver, and evaporator, for controlling the temperature of a served space via hot gas heating and cooling cycles. The receiver is selectively pressurized during a hot gas heating cycle, pressurizing the receiver at low ambient temperatures as sensed by compressor head pressure, and terminating or preventing receiver pressurization above a predetermined head pressure. This is useful for transport refrigeration systems which have a single compartment to condition, and it is even more useful in compartmentalized transport refrigeration systems having two or more compartments to condition.
