A quality determination apparatus includes a state detector and a main processing unit. The state detector detects a state index. The state index is an index indicating a state of a target article contained in a storage space where an internal environment is controlled. The main processing unit performs a determination operation. The determination operation is an operation of determining whether a sign condition indicating a sign of degradation of the target article is met based on the state index detected by the state detector.

Methods and systems are provided for operating a climate control system. In one example, a method for operating a vehicle climate control system includes modeling a pressure in a heat pump downstream of an exterior heat exchanger an upstream of an expansion valve. The method also includes operating the expansion valve to cool a vehicle cabin using the modeled pressure in conjunction with a temperature from a sensor positioned upstream of the expansion valve and downstream of the exterior heat exchanger.

A vehicle climate control system uses infrared image-based measurements of an occupant of a vehicle seat and other environmental information to adaptively and predictively generate the heating, cooling, and/or ventilating effects. An infrared image-based sensor senses data regarding an occupant of the vehicle seat. An apparatus generates heating, cooling, and/or ventilating effects in and/or around the seat. A controller is responsive to the data from the infrared image-based sensor for controlling the operation of the apparatus for generating heating, cooling, and/or ventilating effects. Depending upon the amount of data that has been received by the controller, the apparatus for generating heating, cooling, and/or ventilating effects is operated in either a standard mode, an adaptive mode, or a predictive mode.

A vehicle cabin air temperature controller includes a two-position three-way solenoid valve with one inlet to take in coolant supplied by a pump, a first outlet to supply a cooling leg, and a second outlet to supply a bypass leg. The vehicle cabin air temperature controller also includes a controller to control flow of the coolant via the first outlet and the second outlet of the solenoid valve, and a cabin air heat exchanger to obtain an input coolant based on the control of the flow via the first outlet and the second outlet and to provide cooled cabin air to the vehicle cabin. The control of the flow of the coolant via the first outlet and the second outlet controls a flow rate of the input coolant.
