In a vehicle air-conditioner safety device, in the case in which an abnormality has occurred in a heating device that heats coolant with a heater: it is determined whether or not the abnormality is a restorable abnormality or a non-restorable abnormality; when the abnormality is determined to be the restorable abnormality, it is determined whether or not the restorable abnormality has been removed; heating by the heater is prohibited when the restorable abnormality or the non-restorable abnormality has occurred; and heating by the heater is restored when the restorable abnormality has been removed after heating by the heater is prohibited due to occurrence of the restorable abnormality. With the above-mentioned vehicle air-conditioner safety device, in the case in which the restorable abnormality has occurred in a heating device for a vehicle air-conditioner and the restorable abnormality has not been removed, because heating by the heater is prohibited, it is possible to prevent repetitive restoration and halt of heating by the heater.

A dynamic airflow distribution system (120) within an interior space of a transport unit (100) includes a dynamic airflow distributor (122), a plurality of spacing devices (130), and a plurality of distributor gap closing mechanisms (136). The dynamic airflow distributor forms an airflow passage with a ceiling (108) of the transport unitextending along a longitudinal direction of the transport unit. The plurality of spacing devices form a plurality of gaps (132) between the ceiling and the dynamic airflow distributor. Each of the distributor gap closing mechanisms is associated with a corresponding gap of the plurality of gaps. Also, each of the plurality of distributor gap closing mechanisms (136) controllably opens and closes the corresponding gap of the plurality of gaps.

A vehicle air-conditioning device is a heat pump type vehicle air-conditioning device including an external heat exchanger that performs heat exchange between refrigerant flowing the inside thereof and outside air. With the vehicle air-conditioning device, a controller functions as a temperature-difference calculation unit that calculates the temperature difference ”T between the refrigerant in a refrigerant flow path on the exit side of the external heat exchanger and the outside air, and in addition, the controller functions as a frost formation determination unit that determines that frost formation is caused on the external heat exchanger on the basis of the elapsed time tn of a state in which the temperature difference ”T is equal to or larger than a frost-formation temperature difference at which the frost formation may be caused on the external heat exchanger.

摘要:
The invention mainly relates to an air-conditioning unit in which at least one first air stream and one second air stream to be treated flow through an evaporator, defined by a longitudinal separation wall, one portion of which extends upstream from the evaporator to an end located near the evaporator. The air-conditioning unit of the invention is essentially characterised in that a temperature sensor (9, 9a, 9b) is arranged: longitudinally facing the end (7) of the portion (6a) of the longitudinal separation wall (6) located upstream from the evaporator (2); and between the first (F1a) and second (F2a) air streams passing through the evaporator (2).

The invention relates to a device (D) for estimating a first temperature in an enclosure (H) supplied with air treated by a heating/air-conditioning apparatus (IC) including a supply valve (V1) controlling the supply of said enclosure with outside air and/or recirculated air from a first zone (Z1) of the enclosure (H), an evaporator (EV) cooling the air supply such as to produce cooled air intended for the air outlets of the enclosure (H), and intake means (V3-V5) controlling access to the air outlets. Said device (D) includes control means (MCT) for controlling the placement of the supply valve (V1) and of the intake valves (V3-V5) in positions in which said valves respectively supply the apparatus (IC) with recirculated air and of the air outlets (S1) separated from the first zone (Z1), and for subsequently estimating the first temperature from a second air temperature measured between the supply valve (V1) and the evaporator (EV), following the placements.
摘要:
Systems and methods for providing an improved strategy for controlling a variable speed water pump in a vehicle. In some embodiments, more than one water pump speed function is calculated based on values obtained from vehicle sensors, and a controller chooses among the water pump speed function results to set a water pump speed. In some embodiments, the water pump speed is increased when driveline torque is greater than a threshold amount for an amount of time that varies based on the driveline torque. In some embodiments, ambient temperature is considered while determining whether the water pump should provide full coolant flow to an auxiliary coolant loop of a trailer.
