An automotive air conditioning system comprising: an air cooling circuit including a compressor, a condenser, an expansion valve and an evaporator; an air heating circuit, including a flow rate regulation solenoid valve arranged to regulate the flow rate of a heat transfer fluid through the heater; and an electronic control unit. The electronic control unit is configured to receive a measured evaporator air temperature and a set cabin air temperature and to switch the operating condition of the compressor when the measured evaporator air temperature is higher or lower than at least one on/off threshold temperature computed based on the set cabin air temperature.

One examples provides an automotive air-conditioning system provided with: a thermal unit having a condenser and an evaporator configured to be traversed by a refrigerant fluid and a hydraulic circuit, which is configured to be traversed by a carrier fluid and has a first portion provided with a first heat exchanger, a second portion provided with a second heat exchanger, a hot portion extending through the condenser, and a cold portion extending through the evaporator, a valve device being configured to connect selectively either the hot portion or the cold portion to the first portion and the second portion.

Automotive air-conditioning system

A motor-vehicle is provided with an auxiliary cooling system, having a low temperature cooling liquid, entirely independent from the cooling circuit of the engine and including a radiator located at the front part of the motor-vehicle facing the radiator of the cooling circuit of the engine. The auxiliary cooling circuit comprises one or more auxiliary radiators which are connected parallel to the radiator of the auxiliary circuit and which are constituted by motor-vehicle body components.

An air-conditioning system () for an environment, in particular for the passenger compartment of a vehicle, is provided with an evaporator () and a compressor () coupled to the evaporator (). In a system () for controlling the air-conditioning system (), a control electronics () switches an operating condition of the compressor () when the temperature of the air leaving the evaporator () has a pre-set relation with a threshold temperature (T). The control electronics varies the value of the threshold temperature (T) as a function, in at least certain operating conditions, of a set-point temperature (T), required by a user of the air-conditioning system (), so as to reduce the energy consumption associated to the air-conditioning system.

System and method for controlling the air-conditioning system of a vehicle with reduced energy consumption

Described herein is a system for controlling an air-conditioning system within an environment, in particular the passenger compartment of a vehicle, said system comprising a plurality of sensors designed to detect quantities representing the thermal comfort of the occupants and an electronic control unit (ECU), which calculates, on the basis of said quantities, a temperature indicating the thermal comfort of the occupants of the environment, on the basis of which the actuator devices of the air-conditioning system are driven.

A flow of air coming out of a louver facing the internal space of the passenger compartment of a vehicle is oriented, exploiting the Coanda effect, in an area adjacent to a first surface of the passenger compartment or in an area adjacent to a second surface of the passenger compartment.

Device for distribution of air within the passenger compartment of a vehicle

A control device for an air-conditioning system of a vehicle comprises an evaporator, a compressor with externally controlled variable displacement, and an expansion valve. The control device comprises a control block that receives a reference temperature indicating a desired temperature of the air downstream of the evaporator, and an effective temperature of the air present downstream of the evaporator. The control device-supplies a control signal for the compressor to bring the effective temperature substantially equal to the reference temperature. An observer module receives the control signal and supplies a temperature disturbance indicating an estimate of the oscillatory effect generated by an expansion valve on the temperature of air downstream of the evaporator when a compressor is driven by the control signal. An adder block removes from the effective temperature the temperature disturbance so as to eliminate the oscillatory effect on the effective temperature downstream of the evaporator.

A device and method for automatically preventing misting of the windscreen of a vehicle, wherein a number of sensors determine ambient conditions capable of misting the windscreen, and, upon such ambient conditions occurring, an electronic central control unit automatically activates the air-conditioning system of the vehicle to prevent the windscreen from misting. The device has and the method utilizes a radiant mean temperature sensor arranged inside the vehicle passenger compartment to measure temperature inside the passenger compartment. The radiant mean temperature sensor () has a field of view including at least part of the windscreen.
