Problems solved by technology

[0002] Roof-mounted air-conditioning vehicles use the roof space, and the roof-mounted air conditioner is generally installed on the roof. However, because of the installation of the roof-mounted air conditioner, the air-conditioning condenser is exposed to the sun on the roof, resulting in poor heat transfer efficiency in direct exposure to high-temperature environments. high
At the same time, due to the high density of people in the bus and the long driving distance of the bus and the good airtightness of the car body, it is difficult for the general car air-conditioning system to ensure the air quality in the car

Embodiment 1

[0034] see figure 1 , the present embodiment provides an air-conditioning exhaust cooling recovery system for vehicles, including: a fresh air device 2, an exhaust device 3, and a roof-mounted air-conditioning assembly 1;

[0035] The fresh air device 2 is arranged at the rear of the vehicle, and is used to take wind from the outside to obtain fresh air, and inject the fresh air into the roof-mounted air-conditioning assembly 1;

[0036] The roof-mounted air-conditioning assembly 1 is arranged on the top of the vehicle for cooling the fresh air and sending the cooled fresh air into the vehicle, wherein the roof-mounted air-conditioning assembly 1 is provided with a condenser on the outside of the vehicle, and the condenser is used for fresh air cooling;

[0037] The exhaust device 3 is arranged on the top of the vehicle and is positioned at the front side of the roof-mounted air-conditioning assembly 1. The air outlet 31 of the exhaust device 3 faces the condenser. The air i...

Embodiment 2

[0050] see Figure 8 , the present embodiment provides a method for recovering cooling capacity of air-conditioning exhaust air for vehicles based on Embodiment 1, comprising the following steps:

[0051] S1: Extract the air outside the vehicle to form fresh air, and input the fresh air to the roof-mounted air-conditioning assembly on the top of the vehicle for cooling to form cold air;

[0052] S2: transfer cold air into the vehicle to cool down the temperature inside the vehicle;

[0053] S3: extract the air inside the vehicle to form circulating air, and mix the circulating air with fresh air to form circulating cooling inside the vehicle; extract the air inside the vehicle to form recycled air, and direct the recycled air to the roof-mounted air conditioner assembly The condenser is discharged to use the exhaust air cooling capacity to cool the condenser.

[0054] The present embodiment is described in detail now:

[0055] Specifically, the outside air of the vehicle is...

Abstract

The invention discloses an air conditioner exhaust cold energy recovery system and method for a vehicle. The recovery system comprises a fresh air device, an air exhausting device and a top-mounted type air conditioning assembly; the fresh air device is arranged on the vehicle rear part of the vehicle and used for obtaining fresh air from the outside and injecting the fresh air into the top-mounted type air conditioning assembly; the top-mounted type air conditioning assembly is arranged at the top of the vehicle and used for cooling the fresh air and sending the cooled fresh air into the vehicle; and a condenser of the top-mounted type air conditioning assembly is arranged on the outer side of the vehicle and is used for cooling the fresh air; and the air exhausting device is arranged atthe top of the vehicle and located between the vehicle head of the vehicle and the top-mounted type air conditioning assembly, an air exhausting outlet of the air exhausting device faces the condenser, and the air exhausting device is used for extracting cold air in the vehicle and discharging the cold air to the condenser to improve the heat transfer efficiency of the condenser. The air conditioner exhaust cold energy recovery system and method for the vehicle have the technical characteristics of improving the efficiency of the condenser, energy recovery and utilization, and improving the air quality in the vehicle.

Description

technical field [0001] The invention belongs to the field of air-conditioning systems, and in particular relates to an air-conditioning exhaust cooling capacity recovery system and recovery method for vehicles. Background technique [0002] Roof-mounted air-conditioning vehicles use the roof space, and the roof-mounted air conditioner is generally installed on the roof. However, because of the installation of the roof-mounted air conditioner, the air-conditioning condenser is exposed to the sun on the roof, resulting in poor heat transfer efficiency in direct exposure to high-temperature environments. high. At the same time, due to the high density of people in the bus and the generally long driving distance of the bus and the good airtightness of the car body, it is difficult for the general on-board air conditioning system to ensure the air quality inside the bus. Contents of the invention [0003] The technical purpose of the present invention is to provide an air-cond...
