Pipe, fresh air air inlet pipe and air draft escape pipe pass through top of car respectively and connect with blast cap, to guarantee entrance and the room of outdoor fresh air
The discharge of interior exhaust gas；Because roof space is limited, air draft escape pipe is arranged to unobstructed mode, built-in exhaust blower, effectively to inhale
Enter the return air in roof upper space；Fresh air escape pipe need to access air-conditioner set return air inlet, therefore add bellows, and fresh air is flowed to
Horizontal direction is switched to by vertical direction.Primary efficient filter screen is installed, at the beginning of material is single layer in fresh air air inlet pipe and air draft air inlet pipe
Filter cotton is imitated, to mitigate the pollution to Total heat exchange core, is prolonged its service life；It is provided with Air Filter in air draft escape pipe,
Prevent foreign matter from entering.Entire rail vehicle total-heat exchanger is set as removably, when needing replacing primary efficient filter screen, Air Filter
And when Total heat exchange core, it is convenient for disassembly and is replaced from length direction.
Compared with prior art, the utility model has the beneficial effects that：
1, total-heat exchanger is a kind of energy-efficient heat recovery apparatus, by the waste heat in recycling exhaust to introducing air-conditioning
The fresh air of system is preheated or is pre-chilled, before fresh air enters the room or the surface air cooler of air-conditioner set carries out heat and wet treatment, drop
Low increase fresh air enthalpy.Air-conditioning system load is effectively reduced, saves air conditioning energy consumption and operating cost.
2, it is limited by the limitation of installation space, for rail vehicle, is designed in roof space, product with compact structure,
Design is mounted on car body top, can satisfy the mounting conditions such as size, weight；Total-heat exchanger and air-conditioner set unit is effective
In conjunction with not influencing the indoor air flow field of visitor, while Load Evaporator and compressor power consumption can be reduced, more small-sized sky can be selected
Adjust unit；Total-heat exchanger is placed on outside air-conditioner set, mutually indepedent with former air-conditioner set, does not influence the use peace of air-conditioner set
Dress, can comparatively fast apply；The particularity of rail vehicle environment is considered simultaneously, and flow of personnel amount is big, and air is muddy, therefore designs only
Special filter device, to reach the target of purification air quality, in view of later period maintenance, product is design back with modular removable
Scape is replaced convenient for the use of Total heat exchange core and filter screen, to facilitate subsequent cleaning, maintenance and maintenance.
3, total-heat exchanger designs the Total heat exchange of different automobile types and operating condition on the rail vehicle in conjunction with air-conditioner set
The overall configuration of device reduces unit heat and wet treatment load using diamond shape Total heat exchange core, realizes that heat exchanger effectiveness improves
50%, the new wind load of rail vehicle is effectively reduced, breaks through the high problem of railcar air conditioning energy consumption for a long time.
