An evaporative cooling method and equipment with air exhaust and cold recovery

Abstract

The invention relates to an evaporative cooling method and equipment with an air exhaust function and a cooling capacity recovery function. An air supply pipe and an air exhaust pipe are integrated into a dual-layer pipeline or an integrated double pipeline to be communicated with the equipment and a cooled place, and therefore airflow opposite in air outlet direction and airflow opposite in air return direction can flow in the pipeline at the same time. The thickness of a heat exchanger is small, and the size, in the width direction, of a system is greatly lowered. The two ends of a fan motor are each provided with an axial flow fan blade, and therefore the overall cost is reduced, and the inner structure is compact. The ball wetting efficiency is high and can be 95%-115%. Therefore, according to the equipment with the volume similar to that of an evaporation air conditioner in the prior art, on the premise of increasing little cost, the air exhaust function and the cooling capacity recovery function are additionally added. An additional air exhaust system does not need to be arranged on a building envelope structure like the existing evaporation air conditioner, the system structure is compact, pipeline arrangement is attractive, and the engineering cost is low.

Description

technical field [0001] The invention relates to air-conditioning technology, in particular to an evaporative air cooler system, especially an evaporative cooling method and equipment with air exhaust and cold recovery. Background technique [0002] In the prior art, the traditional evaporative air conditioner system has many disadvantages: [0003] 1. In the prior art, the air supply and exhaust air are set separately, that is, the air conditioner only has the air supply function and has no exhaust air function. In order to balance the indoor and outdoor pressure difference, positive pressure exhaust is generally carried out by using the existing doors, windows and other gaps of the building. [0004] 2. In the prior art, for buildings with a small exhaust area, such as some high-end buildings with high appearance requirements, it is not possible to artificially open large-area exhaust outlets on the walls or glass curtain walls, and an additional exhaust system needs to be...

Problems solved by technology

[0010] In order to solve the problem that the air supply and exhaust air of the evaporative air conditioner system in the prior art are separately set, the problem that the exhaust system needs to be added separately, the structure of the added exhaust system is complicated and the cost is high, and the first-stage direct evaporation, cooling For the problem of small amplitude, the present invention proposes a method and equipment for evaporative cooling with air exhaust and cooling capacity recovery, which is a technical solution to solve the above-mentioned many disadvantages at one time
