Systems and methods are provided for temperature regulation in an autonomous vehicle. In particular, systems and methods are provided for regulating the interior temperature of a delivery container in an autonomous vehicle. In various implementations, the delivery container includes one or more compartments, and a thermal management system is provided for regulating the temperature of each of the compartments.

An air flow controller for an air cleaner and an air cleaner are provided. The air flow controller may include a fan, and a housing, the fan being provided in the housing and the housing being movable from an initial horizontal position in which the air flow controller directs air flow in a vertical direction to an inclined position in which the air flow controller directs air flow in a diagonal direction.

A dual mode thermal actuator (hereafter the actuator) includes a first cup defining a first chamber filled with thermally-responsive wax and a second cup defining a second chamber filled with thermally-responsive wax. A piston is disposed between the first and second cups. A first guide is received by the first cup. The first guide surrounds the piston and extends axially away from the first cup. A second guide is received by the second cup. The second guide surrounds the piston and extends axially away from the second cup. Expansion of the wax in the first chamber or expansion of the wax in the second chamber causes the actuator to go from a retracted position to an extended position. Expansion of the wax in the first chamber and expansion of the wax in the second chamber also causes the actuator to go from the retracted position to the extended position.

A failsafe assembly for use with a thermostat that includes a housing that defines a housing interior, and first and second thermoswitches disposed in the housing interior. The first thermoswitch includes an open and a closed state and is normally in the open state. The first thermoswitch is configured to switch to the closed state when an ambient temperature drops below a predetermined lower threshold temperature and the first thermoswitch is configured to switch back to the open state when the ambient temperature rises above a predetermined first safety temperature. The second thermoswitch includes an open and a closed state and is normally in the open state. The second thermoswitch is configured to switch to the closed state when the ambient temperature exceeds a predetermined upper threshold temperature. The second thermoswitch is configured to switch back to the open state when the ambient temperature drops below a predetermined second safety temperature.

A thermostatic actuator for a radiator valve includes a thermostat mechanism configured to passively open the valve when an environmental temperature is less than a set point and to close the valve when the temperature is greater than the set point. A set point adjustment mechanism draws power from a power supply to selectively drive unitary movement of the thermostat mechanism to adjust the set point. Multiple actuators are used in a zoned radiant heating system in which a controller is operatively connected to the set point adjustment mechanism of each actuator to selectively transmit a control signal to actuate the set point adjustment mechanism to drive unitary movement of the respective thermostat mechanism to adjust the respective set point.
