A vehicle climate control system includes an air conditioning unit including an exterior heat exchanger, an interior heat exchanger, an evaporator, a compressor, a first expansion valve, and a second expansion valve. A seat coil is embedded in a vehicle seat and connected to the air conditioning unit through a first inlet passage, a first outlet passage, a second inlet passage, and a second outlet passage. The compressor is selectively connected to the exterior heat exchanger, the evaporator, the interior heat exchanger, and the seat coil. The first expansion valve is selectively connected to an outlet of the exterior heat exchanger, an inlet of the evaporator, and the seat coil. The second expansion valve is selectively connected to an outlet of the interior heat exchanger, an inlet of the exterior heat exchanger, and the seat coil air conditioning unit.

This disclosure describes a system and method for displaying an indicator when temperature and fan adjustments occur which may cause passengers potential discomfort. Discomfort may be caused by deviations of expected air temperature, fan speed, or both. For example, when a desired temperature is set to seventy-two degrees Fahrenheit (72° F.), colder air at sixty degrees Fahrenheit (60° F.) may be used to bring down the temperature within the vehicle which may be at ninety degrees Fahrenheit (90° F.). The temperature difference between the desired temperature of seventy-two degrees Fahrenheit (72° F.) and the incoming air at sixty degrees Fahrenheit (60° F.) may be above a threshold comfort level, such as two degrees Fahrenheit (2° F.). When this happens, the system may provide the indicator to the passengers. Indicators for a fan speed may also be shown when discomfort may exist. Through these indicators, the passengers may recognize that the threshold for comfort has been exceeded.

A transport refrigeration system comprising: a refrigerated compartment, a refrigeration unit operably coupled to the refrigerated compartment, and a controller for controlling the environment within the refrigerated compartment by controlling the refrigeration unit; a container for storing perishable goods; and a wireless module secured to the container and configured to store a target container temperature; wherein the controller is configured to: receive the target container temperature from the wireless module responsive to the container being placed in the refrigerated compartment; and control the environment within the refrigerated compartment by controlling the operation of the refrigeration unit in accordance with the target container temperature.

An automotive vehicle includes a housing, a plurality of fans arranged relative to the housing, a processor contained by the housing that generates control signals for the fans, and control circuitry including sensors that detect parameters associated with the housing and fans, and logic gates that, based on signals from the sensors, selectively generate output that interrupts the control signals and drives the fans.

An abnormality diagnosis device that performs an abnormality diagnosis on a blower system that sends air to a plurality of air receiving objects obtains a target operating state of an airflow control device that controls airflow to the air receiving objects, obtains a temperature detected by a temperature sensor that detects a first temperature as a temperature of air fed to a first air receiving object as one of the air receiving objects or a temperature of the first air receiving object, estimates the first temperature, based on the target operating state of the airflow control device, and performs abnormality diagnosis on the airflow control device. The abnormality diagnosis device determines that there is an abnormality in the airflow control device, when a difference between the detected first temperature and the estimated first temperature is equal to or larger than a predetermined first reference value.

An inspection system includes a thermal camera and an inspection processor. The thermal camera is mountable on a vehicle and configured to perform imaging of a heat transfer part of heating and cooling equipment mounted on the vehicle. The inspection processor is configured to execute, after causing the heating and cooling equipment to start operation, operation check inspection of determining whether the heating and cooling equipment normally operates on the basis of an image of the heat transfer part obtained by the imaging by the thermal camera, and to, in executing the operation check inspection, perform a modification process of modifying an imaging state of the thermal camera to enable the heat transfer part to be imaged by the thermal camera.

Provided is an air-conditioning device for a vehicle, including: a cooling device configured to cool air passing through a duct; a heater core, which is arranged in the duct on a downstream side of airflow with respect to the cooling device, and is configured to use an engine coolant as a heat source to heat the air; a water valve provided in a coolant circulation system on an upstream side of the heater core; and a controller configured to control those components, in which the controller is configured to decrease an opening amount of the water valve in a predetermined cooling mode. The control is configured to, when the opening amount of the water valve is decreased, decrease a rotational speed of a compressor of the cooling device, and increase a target evaporator temperature of an evaporator of the cooling device, thereby decreasing cooling performance of the cooling device.

A system in a vehicle configured to control the temperature of a temperature controlled vehicle compartment. The system includes: a temperature controlled vehicle compartment configured to be cooled and/or heated; and a processing circuitry operatively connected to the temperature controlled vehicle compartment configured to cause the system to: detect at least a first attribute of at least a first object within a predetermined distance from the vehicle, activate any of cooling or heating of the temperature controlled vehicle compartment based on the at least first attribute of the at least first object.

An electronic control unit is applied to an air conditioner, the air conditioner including a heating unit which heats a heat medium, a casing which allows an air flow to circulate toward a compartment, a blower which generates the air flow in the casing, and a heat exchanger disposed in the casing that heats the air flow by exchanging heat between the heat medium heated by the heating unit and the air flow. The blower air volume of the blower is controlled based on a first candidate value determined based on an estimated blowing temperature, and a second candidate value determined based on a required blowing air temperature and the estimated blowing temperature. The second candidate value is set as a predetermined value when a warm-up operation of the heating unit is completed.
