Disclosed is a method of operating a trailer refrigeration unit of a refrigerated trailer system comprising setting a cargo hold set point temperature through a user interface; urging an airflow along a flowpath from a return air inlet port, through an evaporator of the trailer refrigeration unit, and to a supply air outlet port of the trailer refrigeration unit; monitoring a return air temperature of the airflow flowing through the return air inlet port; monitoring a supply air temperature of the airflow flowing through the supply air outlet port; heating the airflow flowing through the supply air outlet port when the return air temperature is less than the cargo hold set point temperature; and stopping heating of the airflow flowing to the supply air outlet port when the return air temperature is less than the cargo hold set point temperature and the supply air temperature reaches a threshold.

When a vehicles cab temperature reaches 120 degrees Fahrenheit (the medically designated point when heatstroke occurs), our invention monitors the temperature and on reaching 120 F, actuates either/or, interior or exterior, audible and visual warnings to summon help. Can control electric doors, windows and with an added on remote engine starter, start the car and turn on the air conditioner. Our invention meets the USPTO rules for being new, useful, unique and non-obvious.

Systems and methods for heating and cooling a vehicle using a heat pump are disclosed herein. In one embodiment, a system for heating and cooling the vehicle includes a heat pump having: a compressor located in an engine compartment of the vehicle, and an evaporator located in a sleeper or a cab of the vehicle. The system also includes a controller for selecting a cooling mode or a heating mode for the heat pump. In one embodiment, the system includes a clutch for engaging the compressor with a transmission of the vehicle.

A vehicle climate control assembly for modulating a temperature of a passenger compartment includes a solar panel, a battery, a heating and cooling unit, a temperature sensor, and a controller, all of which are mountable to a vehicle. The battery is operationally engaged to the solar panel, which is mountable to an exterior surface of the vehicle. The heating and cooling unit is in fluidic communication with the passenger compartment of the vehicle and is operationally engaged to the battery. The temperature sensor and the controller are mountable within the passenger compartment. The controller is operationally engaged to the solar panel, the battery, the heating and cooling unit, and the temperature sensor. The temperature sensor measures a temperature of the air in the passenger compartment, positioning the controller to selectively actuate the heating and cooling unit to modulate the temperature within the passenger compartment.

A system includes a blower, a blower sensor, and at least one processor. The blower sensor is operably coupled to the blower and configured to obtain blower operational information. The at least one processor is operably coupled to the blower and the blower sensor, and is configured to determine an operational-based power using the blower operational information; determine an operational-based density using the operational-based power; and control the blower using the operational-based density.

A wireless mobile device is used to control an HVAC temperature setpoint in a police vehicle containing a police dog. A wireless signal specifying a commanded temperature setting is checked to prevent malicious adjustments by a hacker. The commanded temperature setting is rejected when it is outside a predetermined range between an absolute minimum and an absolute maximum. When an outside ambient temperature is below a cold-day threshold, then the commanded temperature setting is rejected when it requests a temperature decrease. When the outside ambient temperature is above a hot-day threshold, then the commanded temperature setting is rejected when it requests a temperature increase. Otherwise, when the commanded temperature setting is not rejected as being outside the predetermined range, as being a decrease when below the cold-day threshold, or as being an increase when above the hot-day threshold, then the temperature setpoint is set to match the commanded setting.

Heat-energy exchange device having a first and a second plat heat exchanger, each plate heat exchanger being configured to allow exchanges of heat energy between at least two heat-transfer fluids at different temperatures. The exchange device further includes a distribution member sandwiched between the first and second plate heat exchangers, said distribution member including a series of channels made within it, said channels connecting inlets and outlets of heat-transfer fluid of the first and second plate heat exchangers to connection orifices positioned on said distribution member.

In the method and the apparatus for thermal management and control, and the vehicle according to the present disclosure, an overtemperature threshold of the vehicle may be adjusted in off-road conditions, and/or an operating temperature of the vehicle may be obtained, and driving parameters of the vehicle may be adjusted according to the operating temperature, so as to enhance the heat dissipation performance of the vehicle in the off-road conditions, and avoid that an over-temperature protection of the engine is easily triggered when the engine is operated at a high speed and a high torque in the off-road conditions, resulting in driving experience being affected by limited torque of the engine and turn-off of an air conditioning occurring in the vehicle, and driving safety also being affected, with no high-power fan and large-size radiator being additionally installed, and thus reducing weight and manufacturing cost of the vehicles.

A control system (300) for a transport engineless refrigeration unit (301), the control system including: a controller (302) for communication between a vehicle (307) and a plurality of vehicle devices, the controller comprising: a vehicle data connection (306) for transmitting data to and from a vehicle; a vehicle engine on/off connection (308) for triggering start-up of the vehicle engine; a plurality of device data connections (314), each device data connection transmits data to and from at least one device external to the controller; and a device power connection (313), the device power connection supplies power from the controller to at least one device external to the controller.

This disclosure relates to a system and method for isolating an interior of a motor vehicle from poor outdoor air quality. More particularly, this disclosure relates to a system and method configured to identify conditions associated with poor outdoor air quality and to respond to those conditions by isolating the interior of the motor vehicle from the outdoor environment. An example system includes a selector configured to permit a user to select a drive mode of the motor vehicle, a location system configured to detect a location of the motor vehicle, and a controller configured to issue one or more commands to isolate an interior of the motor vehicle from an environment outside the motor vehicle based on either a selected drive mode or a detected location.
