An air conditioning refrigeration device for a bus, which is characterized in that the air flow is expanded and the hot air is converged

Abstract

The invention discloses an air conditioning refrigeration device for bus, The structure comprises a processing chamber, Sealing plate, anti-collision angle, air outlet, condenser, airflow dredger, capillary tube, evaporator, outlet pipe, the invention relates to an air-conditioning refrigeration device for bus with hot air converged by airflow expansion, the gas output from the diffuser is dividedinto two streams, corresponding to the left and right ends of the bus, which is divert into that two flow tubes of the flow tube, and then ejected through the main jet orifice, so that pedestrians atboth ends of the vehicle can feel the air current passing through them, We know there a car approaching, consciously stay away, When the car is traveling at a higher speed, That is, the air flow supplied by the diffuser chamber is faster, and the intensity of the air flow will break through the auxiliary jet hole and extend to the curved pipe, so that not only the air flow at the left and right ends is larger, but also the air flow will extend to a place a few meters in front of the vehicle, so that people a few meters away can feel the air flow in advance, make timely avoidance actions, havestronger safety performance, and turn waste into treasure.

Description

technical field [0001] The invention relates to an air-conditioning and refrigeration device, in particular to an air-conditioning and refrigeration device for a bus in which hot air expanded by air flow converges. Background technique [0002] The bus is a daily means of transportation for people to go out, but in the hot summer, the heat emitted by the air-conditioning vents at the left and right ends of the rear will make people passing by feel very uncomfortable, and now most of the buses are replaced by electric ones , the sound is small when driving, and people on the side of the road cannot know that there is a car passing by when the horn is not honked. The current technical considerations are not comprehensive and have the following disadvantages: [0003] 1. The hot air from the air-conditioning external unit of the bus is directly sprayed onto the people passing by the roadside, making people feel very hot and dry, which is very unbearable in summer. [0004] 2. ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the object of the present invention is to provide an air-conditioning and refrigeration device for buses in which the air-flow expands and the hot air converges, so as to solve the problem that the hot air radiated by the air-conditioning external unit of the bus is directly sprayed to the people passing by the roadside. It makes people feel very dry and hot, and it is very unbearable in summer. The electric bus is a silent type, and the sound when it is turned on is relatively small, so that people on the bus path cannot know the position of the bus in time. Problems that cause inconvenience and are likely to cause dangerous accidents
