Fresh air system and mobile equipment applying same

Abstract

The invention relates to the technical field of fresh air control, in particular to a fresh air system and mobile equipment applying the same. A fresh air device body is connected with a return air inlet, an air inlet, an air exhaust outlet and an air supply outlet. The air supply outlet is located on one side of a driving cab of a car body, and used for conveying the outside air to the fresh airdevice body; the air exhaust outlet is located on the other side of the driving cab of the car body, and used for exhausting the exhaust gas after the outside air is filtered by the fresh air device body to the outside world; the air inlet is located at an air conditioner exhaust outlet of the car body and used for conveying the purified gas after the outside air is filtered by the fresh air device body to the air conditioner exhaust outlet; and the return air inlet is located at the top of the car body or the side part of the car body and used for exhausting the exhaust gas in the car to theoutside world by the fresh air device body. The fresh air system is simple in structure, internal and external circulation and ventilation of the car body is achieved, and the air quality and the riding comfort degree are improved.

Description

technical field [0001] The invention relates to the technical field of fresh air control, in particular to a fresh air system and a mobile device using the same. Background technique [0002] With economic development and population growth, cars have gradually become an essential tool for people to travel, and how to create a good car environment is very necessary for people to travel. In the traditional sense, the car air conditioner is mainly based on mechanical refrigeration, supplemented by fans, heat exchangers and other equipment to provide a more comfortable environment for the interior of the car, but mechanical refrigeration is not only labor-intensive, but the energy utilization rate is not high. The use of the car will destroy the atmospheric ozone layer; at the same time, the traditional car air-conditioning system uses full return air, so the air quality in the car is poor. In addition, when existing cars are parked outdoors at a relatively high temperature, th...

Problems solved by technology

In the traditional sense, the car air conditioner is mainly based on mechanical refrigeration, supplemented by fans, heat exchangers and other equipment to provide a more comfortable environment for the interior of the car, but mechanical refrigeration is not only labor-intensive, but the energy utilization rate is not high. The use of high-speed air will destroy the atmospheric ozone layer; at the same time, the traditional car air-conditioning system uses full return air, so the air quality in the car is poor

In addition, when existing cars are parked outdoors at a relatively high temperature, the interior of the compartment is a relatively airtight environment, and the temperature inside the compartment will rapidly rise to 50-65°C with the high temperature outside. Formaldehyde, toluene, A large amount of harmful volatile gases (VOC) such as ammonia are released; if the user opens the door and enters the car to start the vehicle, the high temperature inside the car is unbearable, and at the same time the high concentration of harmful volatile gases will make the user feel very uncomfortable. There are many safety and health hazards, and the car users generally have this uncomfortable experience; moreover, if children stay in the car for a long time, there will be problems such as high temperature and hypoxia, and dangerous cases occur frequently
