Abstract

The invention relates to a combined water film evaporative air-conditioning cooling device for a subway station. The current subway air-conditioning ventilation system is high in energy consumption, large in size, and high in engineering investment and operation cost. The device is provided with air inflow distribution control valves, a circulating water pump, water film evaporative cooling module units, an air-water separator and an air outflow collecting cover sequentially in an air inflow direction, wherein the water film evaporative cooling module units, a guide groove, the air-water separator and the air outflow collecting cover are connected into a detachable mobile water collecting tank. The combined water film evaporative air-conditioning cooling device is based on a water film evaporative cold source-free air-conditioning principle of heat and humidity exchange; a modular structure form is adopted, so that the device is convenient to transport, mount, and maintain, simple in system, flexible to control, and high in adaptability, and operates flexibly; the detachable mobile water collecting tank and the air-water separator are convenient to clean periodically, so that bacterial growth is reduced; the quality of treated air is improved; the loss of circulating water is reduced; the water treatment expense and operation cost are lowered; and a water resource is saved.

Description

Technical field [0001] The present invention is a field of air -conditioning refrigeration technology, which involves a combined water film evaporation air -conditioning cooling device of a subway station. Background technique [0002] The temperature and humidity of the underground space of the subway station completely rely on subway ventilation and air -conditioning systems to control. Its functions should not only meet the comfort needs of personnel, but also ensure the normal operation of the equipment.Affect urban landscape.The combined water film evaporation air -conditioning cooling device of the subway station uses the driving force of the renewable energy in nature as the driving force of the hot and wet exchange and transmission of the hot air.Methods have obvious advantages of cleaning, environmental protection, water saving, electricity, and low -cost and low energy consumption.It has a broad application prospect in the central and western regions of my country and a...
