Apparatus and method for tractor cab environment control system

Abstract

A tractor cooling system for chilling the cabin of a trucking tractor vehicle towing a refrigerated trailer. The cooling system is a closed loop recirculation system that utilizes a high thermal conductivity heat exchanger that isolates chilled air and through flexible hoses that supply and return forced air at a constant volume and thereby providing comfort to the driver during warm weather and without idling the engine and while stationary.

1 . A cooling system for interior climate control of a trucking transport tractor comprising in combination:
 a. A transport trucking tractor vehicle;   b. A refrigerated trailer unit;   c. At least one fan blower motor to draw unchilled transport trucking vehicle cabin air at a constant volume, and force circulating air at a constant volume into a closed loop heat exchanger installed in a refrigerated trailer unit;   d. A closed loop heat exchanger in a refrigerated trailer unit that thermally conducts refrigeration from the interior of an operating refrigerated trailer unit and generates chilled air at a constant volume into a transport trucking vehicle cabin;   e. A detachable flexible air hose that circulates pressurized air at a constant volume connected at one end to the output of fan blower motor and at one end to a closed loop heat exchanger;   f. A detachable flexible air hose that circulates chilled pressurized air connected at one end to a closed loop heat exchanger and at one end to and output opening in transport trucking vehicle;   g. A detachable flexible air hose that circulates pressurized air connected at one end to an output opening of a transport trucking vehicle and at one end to the input of a fan blower motor;   h. An electronic climate control switch to set on/off state and blower fan speed located inside the trucking tractor vehicle;   i. At least one deep discharge battery dedicated to power the system;   j. A guard assembly to cover and protect the heat exchanger from shifting goods and inventory during transport;   k. An electronic control for monitoring the condition of deep discharge battery condition and charge/discharge operating state.
