Abstract

The invention provides a direct-expansion evaporation-condensation air conditioning system under an open type tunnel ventilation mode. The direct-expansion evaporation-condensation air conditioning system comprises an evaporator condenser, a compressor, an air conditioning control room, an evaporation-condensation room, and an air inlet duct and an air outlet duct which are connected with the outside. According to the direct-expansion evaporation-condensation air conditioning system, an evaporation side and a condensation side are both subjected to direct expansion heat exchange through a cooling agent, new exhaust air characteristics of a refrigeration season and a transition season under an open type mode are fully utilized, for example, under the small fresh air working condition of the refrigeration season, the outdoor fresh air is used to participate in evaporation-condensation; under the transition season working condition, part of the exhaust air of a station is used to participate in evaporation-condensation; hence, the direct-expansion evaporation-condensation air conditioning system provided by the invention can solve the problem that a cooling tower is difficult to arrange in the metro station, and also can reduce the running energy consumption of the air conditioning system of the metro station.

Description

Technical field [0001] The invention relates to an air-conditioning system for a subway station, especially an energy-saving air-conditioning method in which a direct expansion evaporative condensing air-conditioning system is used to replace the traditional electric refrigeration and cold water system under the open tunnel ventilation mode of the subway. Background technique [0002] At present, underground subway stations that have been built, are under construction, and are under design in various cities are usually equipped with chillers, cooling towers, chilled water pumps, cooling water pumps, and air conditioners to form a traditional air-conditioning system to cool the subway stations. The chiller, chilled water pump, and cooling water pump are installed in the cold water machine room inside the subway station. The air conditioner is installed in the air-conditioning machine room. The cooling tower is installed near the wind pavilion of the subway station (sinking, ground ...
