Abstract

The utility model relates to a unit type passenger room air conditioning unit for subway vehicles, which comprises a control loop connector and a main loop connector, wherein the control loop connector and the main loop connector are arranged outside two ends of an air conditioning unit main body respectively. The unit type passenger room air conditioning unit for subway vehicles can increase the air return area of an air return port and effectively lower the noise of air return current.

Description

The modular guest room of railcar air-conditioning unit

Technical field

The utility model relates to a kind of subway, light rail vehicle with modular guest room air-conditioning unit.

Background technology

Present domestic subway or light rail vehicle guest room air-conditioning unit control loop adaptor union and major loop adaptor union operated by rotary motion are in air-conditioning unit return air inlet or be arranged on air-conditioning generating set main body both sides.When control loop adaptor union and major loop adaptor union are arranged in the return air inlet, need take the available ventilation area of return air inlet, cause return air inlet place wind speed higher, pneumatic noise is big.And electrical cnnector is arranged on the unit both sides, because the new wind sucking hole distance of adaptor union and unit is very near, the air-flow that has destroyed air-conditioning unit both sides that is provided with of adaptor union moves, and can hinder the suction of new wind when vehicle operating.

Summary of the invention

Technical problem to be solved in the utility model is that the defective at prior art exists provides a kind of novel subway vehicle unit formula guest room air-conditioning unit, can effectively reduce noise in the car, keeps the interior air-flow of air-conditioning unit unobstructed.

For achieving the above object, the technical solution adopted in the utility model is, a kind of novel subway vehicle unit formula guest room air-conditioning unit comprises control loop adaptor union and major loop adaptor union, and described control loop adaptor union and major loop adaptor union are located at outside, air-conditioning generating set main body two ends respectively.

Electrical cnnector is arranged on outside, air-conditioning unit two ends, new wind sucking hole is arranged on both sides, electrical cnnector can not have a negative impact to the suction of new wind, can guarantee to greatest extent under static and running condition that the air-conditioning unit sucks sufficient new wind, satisfies the requirement of guest room comfort level.

Compare with traditional electrical cnnector is arranged in the return air inlet, under the situation that unit return air inlet oad remains unchanged, effective return air area of air-conditioning unit return air inlet can increase about 8%.Electrical cnnector is not arranged in the return air inlet, can reduce the return air pneumatic noise effectively, and by the return air inlet noise-reducing design, effectively reduces the noise that imports in the car.Electrical cnnector is arranged on the unit end, can simplify the dismounting step of air-conditioning unit from the vehicle roof dismounting.

As known from the above, the utility model is the modular guest room of an a kind of railcar air-conditioning unit, can increase return air inlet return air area, and effectively reduces the return noise.
