[0051] as attached figure 1 As shown, the device with external air water circulation passive cooling includes indoor area B, evaporative cooling device a, and device C with external air water circulation passive cooling; device C with external air water circulation passive cooling includes inner sunshade facilities 4 and light transmission There is a water heat-absorbing device on the inner sunshade facility 4 itself or / and the light-transmitting enclosure structure; the inner sunshade facility is made of light-transmitting or non-light-transmitting materials; the indoor area B is made of light-transmitting enclosure The indoor space formed by the protection structure and other enclosure structures; the cold water outlet of the evaporative refrigeration device a is connected with the cold water inlet of the water heat absorption device through the water inlet pipe, and a water pump is connected in series on the water inlet pipe, and the evaporative refrigeration device a The r...

Embodiment 2

[0053] as attached figure 1 and 2 Shown, the difference between embodiment 2 and embodiment 1 is: as attached figure 2 As shown, the evaporative refrigeration device a of embodiment 2 adopts a two-stage evaporative refrigeration device; wherein the cold water outlet of the first-stage evaporative refrigeration device is connected with the water inlet of the water heat absorbing device through a water inlet pipe, and the water inlet pipe is connected in series. The water pump and the water outlet of the water heat absorbing device are connected to the water inlet pipe of the evaporative refrigeration device a of this stage through the water outlet pipe; the cold water outlet of the evaporative refrigeration device of the other stage is connected to the water inlet of the sensible cooling end in the indoor area through The water inlet pipes are connected, and the water outlet of the sensible cooling terminal in the indoor area is connected with the water inlet pipe of the evap...

Embodiment 3

[0056] as attached Figures 1 to 3 As shown, the difference between embodiment 3 and embodiments 1 and 2 is that the water heat absorbing device of embodiment 3 has no less than one layer of open wet curtain water on the inner wall of the water cooling cavity of the inner sunshade facility. membrane device with image 3 It is shown as a single layer. The open wet curtain water film device includes a nozzle and a water receiving tank. The cold water of the evaporative refrigeration device is sent to the nozzle through a water pump and a water pipe. The water coming out of the nozzle forms a wet curtain water film and falls into the water receiving tank. , the water in the receiving tank flows back to the water inlet pipe of the evaporative refrigeration device.

Abstract

The invention relates to a method and a device with external air-water cycle passive cooling. The method is carried out as follows: after passing through an evaporative refrigeration device, air outside an indoor area is discharged out from the indoor area; and after passing through the water heat-absorbing device of the device with external air-water cycle passive cooling, cold water sent out from the cold water end of the evaporative refrigeration device is returned to the evaporative refrigeration device by the water returning end of the evaporative refrigeration device. The invention can be applied to an air-flushing system in an air-conditioning system or a system without air supply, utilizes a window integrated passive cooling system to greatly reduce window-obtained heat which is the weak link of building energy consumption and effectively reduce the load of an indoor air conditioner, reduces air output, machine set overall dimension and air hose sectional area, is easy to be matched with architectural space, has low cost and is specially suitable for air conditioning in rooms of home buildings and office buildings.

Description

Technical field [0001] The invention relates to the technical field of heating, ventilation and air conditioning, and is a passive cooling method and device with external air and water circulation, which is applicable to various residences, public buildings and industrial buildings to effectively reduce the solar radiation gain of the light-transmitting enclosure structure of the room. heat. technical background [0002] The "Design Standards for Energy Conservation of Public Buildings" promulgated and implemented by China in 2005 pointed out that China'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] T...
