Abstract
The utility model discloses a subway station ventilating air-conditioning system combining evaporative cooling fresh air and a local machine set. An air inlet kiosk air shaft is connected with an air supply opening of a subway hall through a station air supply airduct. A coarse filter, an indirect evaporative cooling machine set, a direct evaporative cooling machine set and an air supply fan are sequentially arranged in the air supply airduct along the air flow direction. A local evaporation type cold air machine is arranged in the subway hall, and an air outlet kiosk air shaft is connected with an air outlet of the subway hall through an air outlet airduct. The local evaporation type cold air machine is arranged in the subway hall to undertake indoor sensible heat loads while all indoor latent heat loads, fresh air loads and residual sensible heat loads are undertaken through an evaporative cooling fresh air system, independent control of temperature and humidity is achieved, and the requirements of ever-changing indoor temperatures and humidity can be met .
Description
Technical field
The utility model belongs to urban track traffic ventilation, air-conditioning system technical field, relates to the ventilation and air conditioning system that a kind of subway station combines with local unit with the new wind of evaporative cooling.
Background technology
Along with social economy's develop rapidly, subway becomes the major measure that solves the big and medium-sized cities traffic congestion in recent years.Yet there are problems such as comfortableness is not high, energy consumption is big in existing subway air-conditioning.
1, the subway station flow of the people is many, be in underground architectural feature and to the resh air requirement of whole air-conditioning system require bigger, especially big at commuter time section flow of the people, personnel are intensive, require high to the air quality of subway station.
2, subway station is different from other superstructures, and building enclosure is single, no door and window and special underground environment, therefore to the requirement of ventilation than higher.
3, air-conditioning system accounts for about 60% in the subway energy consumption, therefore solves the subway ' s air-conditioning system energy consumption issues, for energy-saving and emission-reduction very important meaning is arranged.
Summary of the invention
The purpose of the utility model provides the ventilation and air conditioning system that a kind of subway station combines with local unit with the new wind of evaporative cooling, and energy consumption is low, and the wind pushing air quality is high, and ventilation is big, and cost is low.
The technical scheme that the utility model adopted is that the ventilation and air conditioning system that subway station combines with local unit with the new wind of evaporative cooling, air intake booth ventilating shaft pass through the station supply air duct and be connected with the air outlet in subway hall; Set gradually low efficient filter, indirect evaporation cooling unit, direct evaporative cooling unit and breeze fan along airflow direction in the supply air duct; Be provided with local evaporation formula air conditioner in the subway hall, air draft booth ventilating shaft is connected with the air outlet in subway hall through wind output channel.
The characteristic of the utility model also is,
Be provided with the air draft blower fan in the wind output channel.
Compare with the traditional mechanical ventilating system, the utlity model has following characteristics:
1) is employed in the air-supply passage and places dual evaporation cooling air-conditioning unit a large amount of new wind are handled, reduce the energy consumption of whole air-conditioning system greatly.
2) local evaporation formula air conditioner is set and bears indoor sensible heat load in the subway hall; Indoor whole latent heat loads, new wind load and residue sensible heat load are then born by the evaporative cooling VMC; Realized that humiture independently controls, can satisfy the requirement that the room humiture constantly changes.
3) compare with traditional mechanical refrigeration air-conditioning system, the energy-saving effect that adopts this hybrid system clearly can be saved operation energy consumption greatly.
4) compare with traditional mechanical refrigeration air-conditioning system, Air Conditioning Facilities need not be set, save construction area, also practice thrift cost of investment simultaneously.
5) need not special artificial mechanism low-temperature receiver is set, power consumption is little.Increase under the little situation at initial cost and operating cost, improved public area, underground station environmental amenity degree greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model ventilation and air conditioning system.
Among the figure, 1. low efficient filter, 2. indirect evaporation cooling unit, 3. direct evaporative cooling unit, 4. breeze fan, 5. air draft blower fan, 6. local evaporation formula air conditioner, 7. supply air duct, 8. wind output channel, D1 is an air intake booth ventilating shaft, D2 is an air draft booth ventilating shaft.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
The structure of the ventilation and air conditioning system that the utility model subway station combines with local unit with the new wind of evaporative cooling, as shown in Figure 1, air intake booth ventilating shaft D1 is connected with the air outlet in subway hall through station supply air duct 7; In supply air duct 7, set gradually low efficient filter 1, indirect evaporation cooling unit 2, direct evaporative cooling unit 3 and breeze fan 4 along airflow direction; The intensive area of personnel is provided with local evaporation formula air conditioner 6 in the subway hall, and air draft booth ventilating shaft D2 is connected with the air outlet in subway hall through wind output channel 8.Be provided with air draft blower fan 5 in the wind output channel 8.Under local evaporation formula air conditioner 6 and supply air duct 7 both actings in conjunction, mixed air communication is crossed the air draft blower fan 5 in wind output channel 8, all discharges from air draft booth ventilating shaft D2.
The course of work of the utility model air-conditioning system:
1, subway station nominal situation in summer operational mode:
Adopt aeration-cooling mode operation, open breeze fan 4, indirect evaporation cooling unit 2 and direct evaporative cooling unit 3; Air-flow gets into supply air duct 7 from air intake booth ventilating shaft D1; Get into indirect evaporation cooling unit 2 through low efficient filter 1; After wet cooling processing such as air carries out,, air is carried out adiabatic humidiflcation more successively through direct evaporative cooling unit 3; Through breeze fan 4, get into subway hall and room air and carry out the wet exchange of heat fully then; Move local evaporation formula air conditioner 6 simultaneously and bear indoor most sensible heat load; Both are common carry out the wet exchange of heat fully with room air after, after wind output channel 8 from air draft booth ventilating shaft D2 discharge, is accomplished whole cooling ventilation process through air draft blower fan 5.
2, subway station spring, autumn the nominal situation operational mode:
At transition season, adopt the mode operation of ventilation, close down indirect evaporation cooling unit 2, direct evaporative cooling unit 3, open breeze fan 4, air-flow is supply air duct 7 from air intake booth ventilating shaft D1 input station, gets into the subway station hall; Alternative is opened local evaporation formula air conditioner 6 when densely populated, and the part is lowered the temperature; Both are common carry out the wet exchange of heat fully with room air after, through wind output channel 8, from air draft booth ventilating shaft D2 discharge, accomplish whole ventilation process through air draft blower fan 5.
