PASSIVE COOLING SYSTEM FOR HOUSES, PREMISES, CARAVANS AND SIMILAR.

摘要

Passive cooling system for booths, premises, caravans and the like. Of special application in the field of mobile phone booths, the system incorporates an exchanger (2) inside the house itself (1), based on a finned tube (3) and at least one fan (4), with the Two other exchangers (5) and (8) external to the booth (1), the first of similar characteristics to the internal accumulator (2), and the second with its finned tube (9) housed inside a tank ( 10) which contains a thermal accumulation substance, such as a polyethylene glycol, the three exchangers being connected in series through a closed circuit (13) in which a pump (12) drives the transmission of thermal transmission fluid. In this way the third exchanger (8) acts as an accumulator that reaches a low temperature during the night and is responsible for absorbing the heat extracted from the house during the hours of the day when the outside ambient temperature is close to or higher than the one inside the house (1).
