Described herein is a automotive air-conditioning system configured to implement a sub-critical refrigerating cycle and comprising a condenser and a fan associated thereto, a compressor, an evaporator, an expansion valve of the non-electronically-controlled type, and an electronic control system configured to receive a signal indicative of the ambient temperature outside the vehicle and to generate a control signal for the fan of the condenser on the basis of the ambient temperature outside the vehicle.

Control of a condenser fan of an automotive air-conditioning system

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.

The system (SC) includes a first, vapour compression circuit (A), including a compressor () with its output connected to a condenser () followed by an expansion device () and an evaporator () having its output connected to the in of the compressor (); a second, absorption circuit (B) with a hygroscopic solution flowing through it in operation and including a regenerator () with semipermeable membranes operable to allow the said solution to give up moisture (water) to a first airflow flowing in the regenerator () in operation, a dehumidifier () with semipermeable membranes arranged downstream of the regenerator () and operable to allow a second airflow to give up moisture to the hygroscopic solution, and a circulation pump (). The first and second circuits (A, B) are connected by at least one heat exchanger () in which the hygroscopic solution flowing through the second circuit (B) gives up heat to the cooling fluid flowing through the first circuit (A).

Climate control system with a vapour compression circuit combined with an absorption circuit

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.
