Adsorption refrigeration system for the production of demineralized water aboard a motor vehicle, motor vehicle and method for producing demineralized water aboard a motor vehicle

An adsorption refrigeration system for the production of demineralized water on board a motor vehicle comprising:

• a condenser, suitable to condense a flow of gas or water vapour,
• an evaporator, suitable to generate a gas or water vapour flow,
• a first and a second adsorbent bed, each containing adsorbent material,
• wherein each adsorbent bed is selectively connectable to the condenser and/or the evaporator by pipes provided with at least one control valve,
• wherein each adsorbent bed is selectively and alternately connectable to a supply circuit of a heating source and to a supply circuit of a cooling source via supply valves,
• wherein the condenser is directly and selectively connectable to the evaporator by a direct branch provided with a relative throttle valve,
• wherein
• said system comprises an inlet valve arranged along an air inlet branch, suitable for selectively making a fluid connection between the air of the environment outside the system and said adsorbent beds, so as to capture water from the external air through an adsorption phenomenon performed by said adsorbent beds and to produce water as a result of the adsorption phenomenon.
