Embodiment Construction
[0008] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0009] The pipeline inside the evaporator 2 is filled with medium. When the fan 1 is working, the indoor hot air flows through the pipeline to dissipate heat. After the medium absorbs heat and vaporizes, it enters the condenser 5 from the ascending pipe 3 . There is a water tank 6 outside the condenser 5, and it is placed in a shady position on a high place of the building. The water is evaporated and cooled by the natural wind blowing outside, and the temperature of the condenser 5 is lowered, so that the medium inside the condenser is finally condensed and liquefied, and collected at the bottom Flow back to the evaporator 2 from the downpipe 4.

The invention discloses a natural-circulation cooling device. According to the natural-circulation cooling device, a substance which has a boiling point close to 25 DEG C is used, and the substance is circulated in a closed system. By means of the above mode, indoor heat is transmitted to the cooling device which is arranged on a shady surface of a building, and thus the purpose of cooling is achieved.
Description
1. Technical field [0001] The invention relates to an indoor air cooling device, in particular to a device for evaporative refrigeration using a medium with a boiling point between 10 and 40 degrees Celsius as a heat exchange medium. 2. Background technology [0002] In the prior art, the evaporative cooling technology utilizes the contact between water and unsaturated humid air to cool down the air or water through the evaporation of water. Since the cooling potential of the atmosphere itself can be used, it is an effective passive cooling method. There are many forms of equipment for heat and mass exchange between air and water, mainly divided into direct evaporative or indirect evaporative coolers and combinations of the two forms. The working process of these devices adopts downstream heat exchange and downstream mass transfer, that is, direct contact between water and unsaturated humid air. And this kind of work process must have irreversible loss in heat and mass tra...
