Evaporation cooling and machine refrigeration-heating combined splash-prevention type air conditioner for bus

Abstract

The invention discloses an evaporation cooling and machine refrigeration-heating combined splash-prevention type air conditioner for bus. The air conditioner comprises an evaporation cooling and machine refrigeration-heating combined system arranged on the outside top of the bus, an air feeding passage arranged on the inner top part of the bus and an air return passage arranged on the rear part of the inner side of the bus, the evaporation cooling and machine refrigeration combined system and the air return passage are both connected with the air feeding passage. Through the adoption of the splash-prevention type air conditioner for bus, the air quality in the bus compartment can be obviously improved and the energy consumption is low.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to a splash-proof bus air conditioner combining evaporative cooling and mechanical refrigeration-heating. Background technique [0002] Most of the air conditioners used on buses in my country are vapor compression refrigeration. The air conditioning system has a complex structure and high maintenance costs, and the use of compressors and fans makes the existing bus air conditioners consume a lot of energy. In addition, the current When the vapor compression type is used for refrigeration, the condenser is mostly cooled by air cooling, and the cooling effect is very limited. [0003] Generally speaking, the large number of passengers in the bus leads to a small movable space, and some passengers smoke and litter in the compartment, which all cause the air quality in the compartment itself to be bad. The heat and humidity treatment is carried out on the...

[0002] Most of the air conditioners used on buses in our country are vapor compression refrigeration. The air conditioning system has a complex structure and high maintenance costs, and the use of compressors and fans makes the existing bus air conditioners consume a lot of energy. In addition, the current When there is a vapor compression type in refrigeration, the condenser is mostly cooled by air cooling, and the cooling effect is very limited

[0003] Generally speaking, the large number of passengers in the bus leads to a small movable space, and some passengers smoke and litter in the compartment, which all cause the air quality in the compartment itself to be bad. The return air in the compartment is treated with heat and humidity, and no fresh air is introduced into the compartment, which results in poor air quality in the compartment
