Embodiment 1

[0071] as attached figure 1 and 2 shown, with the attached figure 1 The difference between the evaporative refrigeration method and device based on the above-mentioned external sunshade cooling is that: figure 2 As shown, the evaporative refrigeration device A of Embodiment 1 is arranged outside the indoor area B, and at the lower part of the external sunshade passive evaporative cooling integrated device C. The air inlet of the evaporative refrigeration device A communicates with the outside of the indoor area B. The air outlet is directly connected with the air inlet of the external sunshade passive evaporative cooling integrated device C.

[0072] The airflow in the air inlet of the evaporative refrigeration device A is all from the air 1 outside the indoor area, the fan 3 is arranged at the air outlet of the evaporative refrigeration device A, and the airflow in the evaporative refrigeration device A is in a negative pressure state. After the air intake air is...

Embodiment 2

[0074] as attached figure 1 and 3 Shown, the difference with embodiment 1 is: as attached image 3 As shown, the evaporative refrigeration device A of Embodiment 2 is arranged at the lower part of the external sunshade passive evaporative cooling integrated device C, the air inlet of the evaporative refrigeration device A communicates with the indoor area B, and the air outlet of the evaporative refrigeration device A communicates with the external sunshade passive evaporative cooling integrated device C. The air inlet of integrated device C is directly connected.

Abstract

The invention relates to an evaporative refrigeration method based on an external sunshading cooling and a plant thereof. The plant comprises an evaporative refrigeration device, an indoor area and an external sunshading passive evaporative cooling integration device, wherein the evaporative refrigerating plant comprises at least one air intake and not less than one air outlet; the external sunshading passive evaporative cooling integration device comprises an external sunshading installation and a translucency containment structure; and not less than one layer of airflow channel formed by the sunshading installation self or between the external sunshading installation and the translucency containment structure is an air exhaust cavity. The invention has the following effects: the heat gain of the room is effectively reduced in summer, the invention is more easy to match in construction and has low cost, is more reasonable and sufficient in the utilization of energy, constructs the channel for indoor and outdoor contact, effectively solves the problem of disorderly air exhausting in an air-condition system, enables the indoor and outdoor air flow to be more smooth, lays a reality basis for the application in large scale of the evaporative refrigeration air conditioning technology in housing construction and other civil architectures, and widens the area suitable for the evaporative refrigeration air conditioners.

Description

Technical field [0001] The invention relates to the technical field of heating, ventilation and air conditioning, and is an evaporative refrigeration method and device based on external sunshade cooling, which is suitable for the air conditioning of various residential buildings, public buildings and industrial buildings, or the method and method for cooling non-air-conditioned rooms. device. technical background [0002] The "Design Standards for Energy Conservation of Public Buildings" promulgated and implemented in 2005 pointed out that my country's building energy consumption has exceeded 1 / 4 of the country's total energy consumption, and will gradually increase to more than 1 / 3 with the improvement of people's living standards. In building energy consumption, HVAC energy consumption accounts for about 27.4%. Therefore, vigorously advocating HVAC energy conservation plays a vital role in building a resource-saving, environment-friendly, low-carbon society. [0003] The ...
