Description
技术领域technical field
本发明属于空调设备技术领域，具体涉及一种家用立管间接-直接两级蒸发式冷气机。The invention belongs to the technical field of air-conditioning equipment, and in particular relates to a household riser indirect-direct two-stage evaporative air conditioner.
背景技术Background technique
目前，传统的家用空调大多为壁挂式机械制冷空调或落地柜式机械制冷空调。由于我国存在较大的人口基数以及较大比例的农村人口，使得家用空调的能耗巨大、难以支付。At present, most of the traditional household air conditioners are wall-mounted mechanical refrigeration air conditioners or floor cabinet mechanical refrigeration air conditioners. Due to the large population base and large proportion of rural population in our country, the energy consumption of household air conditioners is huge and difficult to pay.
目前已大范围推广的家用蒸发式冷气机及冷风扇，因利用低碳环保的蒸发冷却技术，节能效果显著，但蒸发式冷气机及冷风扇只对空气进行直接蒸发冷却处理，降温效果有限，因此限制了蒸发冷却技术在住宅领域的更进一步推广；而单级、多级以及与机械制冷联合的蒸发冷却空调机组，因较大的占地面积，使其难以在住宅领域得以应用。At present, household evaporative air conditioners and cooling fans that have been widely promoted have remarkable energy-saving effects due to the use of low-carbon and environmentally friendly evaporative cooling technology. However, evaporative air conditioners and cooling fans only perform direct evaporative cooling on the air, and the cooling effect is limited. Therefore, the further promotion of evaporative cooling technology in the residential field is limited; and single-stage, multi-stage, and evaporative cooling air-conditioning units combined with mechanical refrigeration are difficult to apply in the residential field due to their large footprint.
因此，开发占地面积小、同时可对空气进行多级蒸发冷却处理的家用蒸发式冷气机，节能意义深远。Therefore, the development of a household evaporative air conditioner that occupies a small area and can perform multi-stage evaporative cooling of air at the same time has far-reaching significance for energy saving.

间接段水箱a8-1内的循环水，在间接段循环水泵a7-1的作用下，经循环水管输送至间接段布水器a10-1，循环水喷淋在立管间接蒸发冷却器a7的换热管内部，并包覆在管内壁，在重力作用下沿管壁下落，与二次空气逆流接触发生热湿交换降温，并与管外一次空气间接换热，最后携带冲刷下的灰尘杂质，落入间接段水箱a8-1，重复循环。The circulating water in the indirect section water tank a8-1, under the action of the indirect section circulating water pump a7-1, is transported to the indirect section water distributor a10-1 through the circulating water pipe, and the circulating water is sprayed on the standpipe indirect evaporative cooler a7 The inside of the heat exchange tube is covered on the inner wall of the tube, and falls along the tube wall under the action of gravity. It contacts with the secondary air countercurrently to exchange heat and moisture to cool down, and indirect heat exchange with the primary air outside the tube, and finally carries the washed dust and impurities. , fall into the indirect segment water tank a8-1, and repeat the cycle.
（2）直接蒸发冷却器中的循环水系统：(2) Circulating water system in direct evaporative cooler:
直接段水箱a5-1内的循环水，在直接段循环水泵a6-1的作用下，经循环水管输送至直接段布水器a13-1，循环水喷淋在填料a14-1的表面，并均匀包覆，同时与流经填料a14-1的一次空气直接接触发生热湿交换，对空气进行等焓加湿降温，最后循环水在重力作用下，落入直接段水箱a5-1内，重复循环。The circulating water in the direct section water tank a5-1, under the action of the direct section circulating water pump a6-1, is transported to the direct section water distributor a13-1 through the circulating water pipe, and the circulating water is sprayed on the surface of the filler a14-1, and Uniform coating, and at the same time, heat and moisture exchange occurs in direct contact with the primary air flowing through the filler a14-1, and the air is subjected to isenthalpy humidification and cooling, and finally the circulating water falls into the direct section water tank a5-1 under the action of gravity, and the cycle is repeated .
