Abstract
The utility model discloses an air path from an air conditioning unit to a passenger room of a coach of a subway train. The air path comprises a ventilator (1), a compressor (2), an expansion valve (3) and an evaporator coil (4) which is communicated with the expansion valve; the evaporator coil (4) is communicated with the compressor (2); and concave-convex staggered noise reduction sponge (6) is coated on the inner surface of an air supply channel (5) of the ventilator (1). The concave-convex staggered noise reduction sponge is paved on the inner wall of the air supply channel, so that noise of the air supply channel is greatly reduced, and the environmental quality of the coach of the subway train is improved.
Description
Technical field:
The utility model relates to the subway carriage air-conditioning technical field, more specifically to the wind path of subway carriage air-conditioning unit to guest room.
Background technology:
Existing subway compartment one of them refrigeration system of air-conditioning unit comprises the compressor, expansion valve of a power 6.5KW, the evaporator coil that is communicated with expansion valve; Evaporator coil is connected with compressor; Its weak point is: because the railcar compact conformation, sound sources such as ventilating set, compressor, condensation fan are very easy to import in the compartment through air-supply passage; And the air-supply passage of ventilating set also can produce big noise in the air-supply process.
The utility model content:
The purpose of the utility model is exactly the deficiency to prior art; And the wind path of subway carriage air-conditioning unit to the guest room that provides; In the noise reduction sponge that the inwall of air-supply passage has been laid the concavo-convex shape that interlaces, so just weakened the noise of air-supply passage greatly, promoted the environmental quality of subway carriage.
The technological solution of the utility model is following:
The wind path of subway carriage air-conditioning unit to guest room comprises ventilating set, compressor, expansion valve, the evaporator coil that is communicated with expansion valve, and evaporator coil is connected with compressor, and the inside face of the air-supply passage of ventilating set is coating the noise reduction sponge of the concavo-convex shape that interlaces.
The beneficial effect of the utility model is: the noise reduction sponge that it has laid the concavo-convex shape that interlaces at the inwall of air-supply passage, so just weakened the noise of air-supply passage greatly, and promoted the environmental quality of subway carriage.
Description of drawings:
The structural representation of Fig. 1 the utility model
Fig. 2 is the cutaway view of air-supply passage
Fig. 3 is the A-A cutaway view of Fig. 2
Among the figure: 1, ventilating set; 2, compressor; 3, expansion valve; 4, evaporator coil; 5, air-supply passage; 6, noise reduction sponge.
The specific embodiment:
Embodiment: see shown in Fig. 1 to 3; The wind path of subway carriage air-conditioning unit to guest room; Comprise ventilating set 1, compressor 2, expansion valve 3, the evaporator coil 4 that is communicated with expansion valve; Evaporator coil 4 is connected with compressor 2, and the inside face of the air-supply passage 5 of ventilating set 1 is coating the noise reduction sponge 6 of the concavo-convex shape that interlaces.
Principle of work: whole air-conditioning unit all is installed in the top in compartment; The air-supply passage 5 of ventilating set 1 is used for the circulation of air; The utility model is coating the noise reduction sponge 6 of the concavo-convex shape that interlaces of one deck at the inwall of air-supply passage, plays the effect of noise reduction, has so just promoted the environmental quality in compartment.
Claims (1)
1. the wind path of subway carriage air-conditioning unit to guest room; Comprise ventilating set (1), compressor (2), expansion valve (3), the evaporator coil (4) that is communicated with expansion valve; Evaporator coil (4) is connected with compressor (2), it is characterized in that: the inside face of the air-supply passage (5) of ventilating set (1) is coating the noise reduction sponge (6) of the concavo-convex shape that interlaces.
