Direct Evaporative Cooling Air Conditioning Units Using Inclined Fill

technical field

The utility model belongs to the technical field of air-conditioning and refrigeration equipment, and in particular relates to a direct evaporative cooling air-conditioning unit using inclined packing.

Background technique

As we all know, the core of evaporative cooling technology is the filler, and the performance of the filler will directly affect the efficiency of the heat exchanger, and ultimately affect the cooling effect of the equipment. Therefore, the research on fillers is of great significance to the development of evaporative cooling technology. However, factors that affect the efficiency of direct evaporative cooling include: spraying water density, wind speed, thickness, specific surface area, and water distribution method and structure of fillers. Therefore, to improve the efficiency of evaporative cooling, start from the simplest aspect, and consider the contact time and contact area between air and water to improve the efficiency of evaporative cooling.

Utility model content

The purpose of this utility model is to provide a direct evaporative cooling air-conditioning unit using inclined packing, setting the inclined direction of the packing to be consistent with the movement direction of water droplets, increasing the contact time between air and water, and improving the heat exchange efficiency of the direct evaporative cooling unit.

The technical solution adopted by the utility model is that the direct evaporative cooling air conditioning unit adopting inclined packing includes an organic unit casing, and fresh air outlets and air supply outlets are respectively arranged on the opposite side walls of the unit casing. In the direction of entry, there are coarse-effect filters, direct evaporative coolers with inclined packing, and blowers in sequence.

The utility model is also characterized in that,

The direct evaporative cooler with inclined packing includes inclined packing, the upper part of the inclined packing is provided with a water distributor, the lower part of the inclined packing is provided with a water collecting tank, and the water collecting tank is provided with a water filter. The water filter is connected to the water distributor through the water supply pipe, the water supply pipe is provided with a circulating water pump, and the inclined packing is inclined from top to bottom along the direction of the wind.

The inclined packing is in the shape of a parallelepiped.

Compared with the existing direct evaporative cooling air-conditioning unit, the direct evaporative cooling air-conditioning unit using inclined packing of the utility model has the following characteristics:

(1) Since the water spraying on the upper side of the filler is affected by the wind speed, the water droplets will move with the direction of the airflow. The inclined direction of the filler is set to be consistent with the movement direction of the water droplets, which increases the contact time between air and water and improves the heat transfer of the direct evaporative cooling unit efficiency.

(2) The direct evaporative cooling air-conditioning unit of the present utility model adopts inclined packing to increase the contact area between the air flow and the windward side of the packing and improve the heat exchange effect between water and air.

(3) The direct evaporative cooling air-conditioning unit of the utility model can greatly reduce the water splashing phenomenon of the filler when the wind speed is too high, and there is no need to install a water baffle, which reduces the length of the unit.

The structure of the direct evaporative cooling air-conditioning unit using inclined packing of the utility model is shown in Figure 1, including an organic unit casing, and fresh air outlets 1 and air supply outlets 6 are respectively arranged on the opposite side walls of the unit casing. A coarse-effect filter 2, a direct evaporative cooler with inclined packing, and a blower 5 are sequentially arranged in the casing according to the incoming direction of the fresh air.

The direct evaporative cooler with inclined packing, as shown in Figure 1, includes inclined packing 4, the upper part of the inclined packing 4 is provided with a water distributor 7, and the lower part of the inclined packing 4 is provided with a water collection tank 3, and the water collecting tank 3 is provided with a water filter, the water filter in the water collection tank 3 is connected with the water distributor 7 through the water supply pipe, the water supply pipe is provided with a circulating water pump 8, and the inclined packing 4 is inclined from top to bottom along the windward direction.

The preferred scheme is that the inclined packing 4 adopts a parallelepiped shape.

The working process of the utility model direct evaporative cooling air conditioning unit is as follows:

In summer, the outdoor fresh air passes through the fresh air outlet 1 and passes through the coarse-effect filter 2 to filter the dust. The blower 5 sends the treated air into the room through the air outlet 6 .

On the one hand, the direct evaporative cooler with inclined packing not only increases the contact area between the airflow and the windward side of the packing, but also the water droplets will move along the direction of the airflow. The contact time with water improves the heat exchange efficiency of the direct evaporative cooling unit; on the other hand, it can greatly reduce the phenomenon of water splashing due to excessive wind speed, and there is no need to set up a water baffle.

The direct evaporative cooling air-conditioning unit of the utility model can realize the effect of equal enthalpy cooling of air.
