Evaporative cooling direct expansion air conditioner system for subway station

Abstract

The invention discloses an evaporative cooling direct expansion air conditioner system for a subway station. The air conditioner system comprises compressor devices arranged in a public area of the subway station, multiple direct expansion type air treatment units which are arranged in parallel, an electronic throttling device and evaporative cooling devices arranged outside exits and entrances of the subway station; inlets of the evaporative cooling devices are connected with outlets of the compressor devices, outlets of the evaporative cooling devices are connected to inlets of the direct expansion type air treatment units which are arranged in parallel through the electronic throttling device, and outlets of the direct expansion type air treatment units are connected in parallel and then connected with inlets of the compressor devices. According to the air conditioner system, by arranging the evaporative cooling devices, heat carried by a high-temperature gaseous refrigerant is directly discharged to the outside atmosphere, and a cooling tower and a water-cooled water chilling unit in a traditional subway station air conditioner system are omitted.

Description

technical field [0001] The invention relates to the field of air conditioning equipment, in particular to an evaporative cooling direct expansion air conditioning system for subway stations. Background technique [0002] The traditional subway station ventilation and air conditioning system adopts the "water-cooled chiller + cooling tower + combined air conditioning unit" system. This traditional system has the following disadvantages: First, the cooling tower occupies the ground and destroys the urban landscape and disturbs the residents. Subway stations are mostly built in urban population density In a relatively prosperous area, setting cooling towers on the ground in this area will damage the urban landscape and affect the daily life and rest of nearby residents; secondly, the water-cooled chillers in the traditional system need to occupy a dedicated machine room outside the civil air duct of the subway station. Increase the amount of civil engineering excavation and con...
