Embodiment 1

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

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

Embodiment 2

[0074] As attached figure 1 with 3 As shown, the difference from 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 shading 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 is connected to the external shading passive evaporative cooling The air inlet of the integrated device C is directly connected.

[0075] The air flow in the air inlet of the evaporative refrigeration device A all comes from the exhaust air 4 in the indoor area, and the fan 3 is arranged at the air inlet end of the evaporative refrigeration device A, and the air flow in the evaporative refrigeration device A is in a positive pressure state. After the inlet air flow is processed by the evaporative cooling device A, the air flow enters the exhaust cavity of the exte...

Embodiment 3

[0077] As attached figure 1 with 4 As shown, the difference from embodiment 1 is: as attached Figure 4 As shown, the evaporative refrigeration device A of Embodiment 3 is arranged in the lower part of the external shading passive evaporative cooling integrated device C. One air inlet of the evaporative refrigeration device A communicates with the indoor area B, and one air inlet communicates with the indoor area B, which correspond to The two air outlets of the evaporative refrigeration device A are directly connected to the air inlet of the integrated passive evaporative cooling device C of the external sunshade.

[0078] The airflow in the air inlet of the evaporative refrigeration device A communicating with the indoor area comes from the exhaust air 4 in the indoor area, and the airflow in the air inlet of the evaporative refrigeration device A communicating with the indoor area comes from the air 1 outside the indoor area. The fan 3 is arranged at the upper part of the air o...

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 cooling method and device based on external shading and cooling. It is suitable for air conditioning in various residential buildings, public buildings, industrial buildings and other rooms, or is a method for cooling non-air-conditioned rooms. Device. technical background [0002] The "Energy-saving Design Standards for Public Buildings" promulgated and implemented in 2005 pointed out: 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, the energy consumption of HVAC accounted for about 27.4%. Therefore, vigorously advocating energy-saving HVAC plays a vital role in building a resource-saving and environment-friendly low-carbon society. [0003] The cooling load borne by a...
