1. the straight swollen cold type ventilation and air conditioning system of subway station machine room type evaporative condenser, including ventilation dynamical system, it is characterized in that, described ventilation dynamical system is located in tunnel, described tunnel includes fresh flue and exhausting duct, described fresh flue and exhausting duct are provided with subway station machine room area at subway station, and the subway station straight swollen cold type of machine room type evaporative condenser that described subway station machine room area is provided with the ventilation for controlling whole system and refrigeration is air conditioning unit;

  • The described subway station straight swollen cold type of machine room type evaporative condenser is air conditioning unit includes refrigeration system, described refrigeration system includes compressor, zonal control apparatus for evaporation condensation and subregion control vaporising device, described compressor, zonal control apparatus for evaporation condensation and subregion control vaporising device are in turn connected to form loop by refrigeration system pipeline, described zonal control apparatus for evaporation condensation is located in exhausting duct, and described subregion control vaporising device is located in fresh flue;

    The described subway station straight swollen cold type of machine room type evaporative condenser is air conditioning unit also includes evaporative condenser water treatment facilities, cross air flow controller, air draft interface, new wind interface, variable air quantity exhaust fan, variable air quantity breeze fan, air-supply interface and return air interface, described evaporative condenser water treatment facilities is connected formation loop with zonal control apparatus for evaporation condensation, described cross air flow controller is located between zonal control apparatus for evaporation condensation and subregion control vaporising device control air mass flow and airflow direction, described variable air quantity exhaust fan and variable air quantity breeze fan are arranged respectively close to air draft interface and air-supply interface;

    Described ventilation dynamical system includes that air separator in exhausting duct outer air separator, exhaust fan, exhausting duct, fire-type air draft control acoustic filter in air-valve, fresh flue outer air separator, breeze fan, air delivery duct, fire-type Xingfeng capsule air-valve and fire-type and mix wind control air-valve;

    The outer air separator of described exhausting duct is located near the exhaust outlet of exhausting duct, and in described exhaust fan and exhausting duct, air separator is sequentially arranged in exhausting duct, and described fire-type air draft controls air-valve and is located between exhaust fan and the outer air separator of exhausting duct;

    Outside described fresh flue, air separator is located near the air inlet of fresh flue, in described breeze fan and air delivery duct, acoustic filter is sequentially arranged in fresh flue, described fire-type Xingfeng capsule air-valve is located at outside breeze fan and air delivery duct between acoustic filter, and described fire-type mixes wind and controls on the air channel wall that air-valve is located between exhausting duct and fresh flue;

    The described subway station straight swollen cold type of machine room type evaporative condenser is air conditioning unit and is provided with fire-type air draft by-pass governing air-valve and fire-type new wind by-pass governing air-valve between tunnel wall, described fire-type air draft by-pass governing air-valve is located in exhausting duct, and described fire-type new wind by-pass governing air-valve is located in fresh flue;

    Realize cooling by indoor air circulation, realize heat radiation by the circulation of air channel outside air, realize heat between side, indoor and outdoor by the straight swollen cold wind kind of refrigeration cycle of evaporative condenser and transmit;

    Inside air circulation is;

    Indoor Thermal humidity load enters the return air confluence area that exhausting duct end is formed, through return air interface, enter air filtration before exhaust-air filter carries out heat exchange to process, subsequently enter zonal control apparatus for evaporation condensation Indoor Thermal humidity load to be replaced, then be discharged to exhausting duct by variable air quantity exhaust fan and finally discharge ground;

    Described cross air flow controller is provided with M1, M2, M3, M4 district, and the most cross air flow controller M1, M3 district closes, the 45 degree of unlatchings the most clockwise of M2, M4 district;

    When air-conditioning all-fresh air runs, air channel outside air circulation is;

    outdoor new wind enters from fresh flue, fire-type Xingfeng capsule air-valve is opened, fire-type mixes wind and controls air-valve closedown, in new wind enters air delivery duct after breeze fan, acoustic filter carries out noise elimination process, fire-type new wind by-pass governing air-valve cuts out, it is air conditioning unit that new wind enters the subway station straight swollen cold type of machine room type evaporative condenser, after entrance unit wind purifying defecator carries out air quality process, wet process of lowering the temperature is carried out in subregion control vaporising device, the air-supply sending into fresh flue end formation through variable air quantity breeze fan splits region, the most cross air flow controller M1, M3 district closes, the 30 degree of unlatchings clockwise of M2 district, the 150 degree of unlatchings clockwise of M4 district;

    The straight swollen cold wind kind of refrigeration cycle of evaporative condenser is;

    coolant is discharged after compressor, enter zonal control apparatus for evaporation condensation through refrigeration system pipeline and coolant is carried out radiating and cooling, lead to refrigeration system pipeline the most again and enter after subregion control vaporising device absorbs heat, coolant returns to compressor, enters next one circulation.
