ABSTRACT:
The invention relates to the air conditioning of a storage compartment and is especially significant for a transport system. Air is circulated between an air tempering zone and the storage compartment, said air tempering zone having air cooling means and air heating means controlled by a thermostat. The thermostat has a wide range set point and depending upon what set point is selected, the thermostat is responsive either to the temperature of the air discharged from the tempering zone or the temperature of the air returning to said zone. When the set point is above a given point and the air is being cooled to near the desired temperature, said desired temperature is accurately obtained by the thermostat first sending a signal from a selected one of the two sensors that provides a step-reduction in the capacity of the cooling means and then sending a signal to a modulating valve that further reduces to the set point the capacity of the cooling means by a modulation reduction.
