A device for protecting an air conditioning system of a vehicle is configured to prevent damage to an air conditioning system due to excessive operation of a compressor or a deficit of a refrigerant by accurately determining whether to operate the compressor even without using a specific sensor that causes an increase in the manufacturing cost of a vehicle.

A sensor device for calculating air temperature includes a support structure, to be traversed by the air and defining a seat having an air inlet and an air outlet, and a sensor arranged inside the seat to detect at least one first value and at least one second value of the air temperature that traverses the seat. The sensor device is configured so that, when detecting the first and second value, the air traverses the seat at a first and at a second speed, at which the sensor has a first and second heat transfer coefficient and first and second radiant power. The ratio between air speeds, heat transfer coefficients, or radiant powers is predetermined. The sensor device can be used with a data processing logic unit that calculates the air temperature starting from the first value, the second value, or the ratios between air speeds and radiant powers.

The present disclosure discloses an air conditioner control method and system, a non-transitory storage medium and a processor. The control system includes an environmental temperature sensor configured to detect a first temperature value of an external environment of a target object; a heat exchanger temperature sensor configured to detect a second temperature value of an outside heat exchanger of an air conditioner system; a speed monitoring system configured to detect a driving speed of the target object; and a control system, connected to the environmental temperature sensor, the heat exchanger temperature sensor and the speed monitoring system, and configured to determine according to the first temperature value, the second temperature value and the driving speed, whether the air conditioner system enters a defrosting mode in a case that the air conditioner system operates in a heating mode.

Disclosed are a vehicle and an air-conditioning control method therefor that are capable of executing an after-blow function for an air-conditioning system without concern about discharge of a battery. The method of controlling an air-conditioning system of an eco-friendly vehicle includes determining a remaining time to a destination when a first condition related to the state of the vehicle and setting of the destination and a second condition related to an indoor temperature of the vehicle are satisfied, determining the state of the air-conditioning system related to condensation water of an evaporator of the air-conditioning system when the remaining time is equal to or less than a first time, and activating an after-blow function to stop the cooling function of the air-conditioning system and to operate a blower based on the determined state of the air-conditioning system.

A computer includes a processor and a memory, the memory storing instructions executable by the processor to heat a passenger cabin of a vehicle, suppress a climate control limiter that prevents an air blower of a climate control component from operating when an engine coolant temperature exceeds a temperature threshold, and actuate a motor on an air pump to introduce air external to the vehicle to the passenger cabin.

A control method of a heat pump system for a vehicle may include a first cooling apparatus having a first radiator, a first water pump, an electrical component, a valve, and a branch line, which are connected by a first coolant line and circulate a first coolant by the first water pump to the electrical component; a second cooling apparatus including a second radiator and a second water pump connected by a second coolant line; and an air conditioning apparatus including a compressor, a heater, an expansion valve, and a heat exchanger which are connected by a refrigerant line circulated with a refrigerant.

In a situation where a temperature in a motor compartment is higher than a temperature of outside air, an inside air introduction rate increasing control is performed in which an inside air introduction rate is changed to be increased on a condition that there is no request for warming an inside of the vehicle cabin, the air conditioner is off, and air is being blown in an outside air introduction mode, and on the other hand, the inside air introduction rate increasing control is prohibited on a condition that there is a request for warming the inside of the vehicle cabin, the vehicular air conditioner is off, and air is being blown in the outside air introduction mode. In this way, heating efficiency can be improved by effectively utilizing the heat in the motor compartment to contribute to warming the inside of the vehicle cabin.

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 thermal management system may include a first cooling circuit cooling PE parts and including a first radiator, a first coolant line circulating a coolant between the first radiator and the PE parts, and a first electric water pump circulating the coolant along the first coolant line, a heat pump system including a compressor compressing a refrigerant, an internal condenser performing a heat exchange between the compressed refrigerant and air supplied inside a vehicle, a refrigerant line circulating the refrigerant between the compressor and the internal condenser, and a heat exchanger for the heat exchange between the coolant and the refrigerant, a flow increase bypass line between the first coolant lines on the entrance and exit sides of the PE parts, and a coolant control valve provided at location where the flow increase bypass line is branched in the first coolant line and controlling a flow direction of the coolant.

A method for controlling a temperature in an interior of a vehicle is provided, wherein the temperature in the vehicle interior is determined with the aid of infrared radiation emitted by the fitments or in the interior, and the air conditioning is adjusted accordingly. A vehicle which is configured to carry out the method is furthermore provided.
