Problems solved by technology

[0004] However, further studies have shown that the above-mentioned existing solutions still have the following defects or deficiencies: First, during the operation of the above-mentioned system, the process of refrigerant being absorbed by the solution is only carried out in a single absorber, regardless of whether the absorber is designed as adiabatic The absorber is still a non-adiabatic absorber, and the large amount of absorption heat released during the absorption process cannot be quickly dissipated into the air, which leads to the problems of high absorption temperature in the absorber and high saturation concentration of the solution, and at the same time causes the absorber The absorption capacity of the internal solution decreases, and the COP (coefficient of performance) of the system will also be relatively low; secondly, when a large amount of absorption heat is directly released into the air, the solution at the outlet of the absorber is pressurized by the solution pump and needs to be exchanged again in the solution. The heat load in the non-adiabatic absorber and its circulating solution air-cooled cooler and solution heat exchanger is large, and a large amount of high-temperature absorption heat is dissipated into the air without being absorbed Recycling
In other words, the existing exhaust gas-based on-board absorption air-conditioning systems cannot achieve good heat dissipation while maintaining good absorption efficiency

Abstract

The invention belongs to the related technical field of vehicle-mounted air conditioners and discloses a vehicle-mounted absorption-type air conditioning system based on exhaust driving. The vehicle-mounted absorption-type air conditioning system based on exhaust driving comprises assemblies such as a generator, a gas-liquid separator, a solution heat exchanger, a high temperature absorber, a lowtemperature absorber, an air-cooled condenser and an air-cooled evaporator, wherein the absorbers are designed in two stages; the specific structures and arranging modes of the absorbers are adjusted;two circulation processes of a refrigerant and a solution are correspondingly improved. According to the vehicle-mounted absorption-type air conditioning system based on exhaust driving, the deflation range can be effectively enlarged, the problem that a lot of absorbed heat is radiated to the air and cannot be used in the traditional scheme is solved, and the phenomenon that the outlet temperature of the low temperature absorber is too high is reduced so that the working performance of the whole refrigeration cycle is obviously improved.

Description

technical field [0001] The invention belongs to the related technical field of vehicle air conditioners, and more specifically relates to a vehicle absorption air conditioning system based on exhaust gas drive. Background technique [0002] The current vehicle air conditioner generally adopts a vapor compression refrigeration cycle, and the shaft power consumed by the compressor comes directly from the vehicle engine. For example, the compressor of a small car is directly driven by the engine, and a large bus needs to be equipped with a special engine drive. Statistics show that automobile air conditioners consume 8%-12% of the power of the engine, of which the compressor accounts for 80%-85%, and the fan accounts for 15%-20%. Insufficient engine power appears, and at the same time affects the use effect of the car air conditioner. In other words, the long-term operation of traditional automotive air conditioners will inevitably consume a large amount of primary energy, whi...
