Bus-based heat collecting and refrigerating device

Abstract

The invention discloses a bus-based heat collecting and refrigerating device. The device comprises a heat collecting system, a lithium bromide refrigerating system and a sensor detection system, wherein the heat collecting system comprises a solar heat collecting module and an exhaust waste heat collecting module, the solar heat collecting module comprises a solar heat collector arranged at the top of a bus and a hot water circulating pump, and water in a water storage tank flows through the solar heat collector to form internal circulation under the action of the hot water circulating pump; the lithium bromide refrigerating system comprises a generator, a condenser, an evaporator, an absorber and a heat exchanger which are sequentially and circularly connected, the evaporator is communicated with the inside of the bus, energy is supplied by the aid of abundant outdoor solar energy in summer and exhaust waste heat of a bus engine, power of the bus is not required, the power performance of the bus is improved, fuel consumption of the bus is reduced, exhaust emission is reduced, compared with a traditional air conditioner refrigerant R12 and the like, the lithium bromide-water which is used as a refrigeration working medium has the advantages that the lithium bromide-water is non-toxic, pollution-free and incombustible, and is clean, environment-friendly and good in safety.

Description

technical field [0001] The invention relates to a bus-mounted technology, in particular to a bus-based heat collection and refrigeration device. Background technique [0002] According to the report data of China's bus industry, the number of buses in China has exceeded 500,000 in 2013, and it is expected to reach 600,000 by the end of the 12th Five-Year Plan. The urban public transportation system with buses as the main body is gradually being established and improved. Urban public transport vehicles account for 10% of urban car ownership, but travel nearly 50% of the total mileage, bearing more than half of the city's passenger pressure. With the development of the automobile industry and the improvement of people's material civilization, people have put forward higher requirements for the environmental protection, energy saving and comfort of public transportation. In response to the hot weather in summer, many buses are now equipped with on-board air-conditioning and re...

AI Technical Summary

Problems solved by technology

[0004] 1. The weather is hot in summer. Due to the large window area of ​​the bus, it is exposed to direct sunlight, coupled with the influence of ground heat reflection, engine radiant heat, and human body heat dissipation, the heat load of the vehicle-mounted air conditioner is relatively large;

[0005] 2. The existing bus air-conditioning system needs to consume a lot of energy, and the refrigerant R12 widely used in the vehicle air-conditioning is the main component that destroys the ozone layer today;

[0006] 3. The air-conditioning refrigeration compressor on the bus is driven by the engine or a special auxiliary motor, so other performances of the vehicle (such as acceleration performance, climbing performance, fuel economy) will be affected to a certain extent
