Cooling method of combined water film evaporative air conditioner in subway station

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 invention belongs to the technical field of air conditioning and refrigeration, and in particular relates to a cooling method for a combined water film evaporative air conditioner in a subway station. Background technique [0002] The temperature and humidity of the underground space of the subway station are completely controlled by the ventilation and air conditioning system of the subway. Its function should not only meet the comfort needs of the personnel, but also ensure the normal operation of the equipment. At present, the air-conditioning and ventilation methods of subway projects are mainly conventional mechanical refrigeration air-conditioning with chillers + cooling towers. The refrigeration system is huge, the energy consumption is large, the project investment and operation costs are high, the noise disturbs the residents, and the cooling tower equipment occupies a permanent land on the outdoor ground. affect the urban landscape.
