Description
Technical field
The present invention relates to a kind of method and device that utilizes residual heat of tail gas of automobile that energy is provided for air conditioning for automobiles as the lithium bromide refrigerating thermal source.
Background technology
Present air conditioning for automobiles all adopts the fluorohydrocarbon refrigeration, and the automobile power that consumes is big on the one hand, strengthens automobile fuel consumption; The discharging of residual heat of tail gas of automobile has strengthened greenhouse effects on the other hand.If utilize residual heat of tail gas of automobile to do thermal source, adopt lithium bromide refrigerating to provide energy for air-conditioning, will reduce the consumption of automobile power, save the energy, also reduced the discharging of residual heat of tail gas of automobile, not only energy-conservation but also environmental protection, and along with being on the increase of automobile quantity, meaning is more long-range.
Summary of the invention
In order to reduce automobile fuel consumption, energy savings reduces the discharging of residual heat of tail gas of automobile simultaneously, and part relaxes greenhouse effects, the invention provides a kind of residual heat of tail gas of automobile that utilizes and is the lithium bromide refrigerating method of thermal source and the fluorohydrocarbon air conditioner refrigerating of the alternative existing automobile of device.
The technical solution adopted in the present invention is: automobile exhaust pipe is divided into two, electronic control valve is housed on every, and the folding mode is always one and opens one and close state.Wherein an arm has conducting strip and passes through generator, for generator provides thermal source.The temperature that the arm exhaust flow comes control generator is regulated in folding by the exhaust branch pipe electronic control valve.After the waste heat heating evaporation of lithium bromide water solution quilt row device arm in generator concentrates, enter in the absorber, after the low temperature and low pressure water vapor dilution in the absorption evaporimeter, deliver to double evaporation-cooling in the generator, periodic duty through solution pump through pipeline and control valve.The high-temperature high-pressure steam that lithium bromide water solution produces when the generator evaporation and concentration, enter the air-cooled condenser condensation through pipeline, condensation is after pipeline and choke valve enter evaporimeter, because the absorption of lithium-bromide solution in the absorber, make in the evaporimeter condensed water constantly evaporation to the environment heat absorption and freeze.Absorbed low temperature and low pressure water vapor enters generator with bromize lithium dilute solution and evaporates once more, carries out time condensation, circulates repeatedly and continuous cooling.
The invention has the beneficial effects as follows by lithium bromide refrigerating to substitute the fluorohydrocarbon refrigeration, reduced the consumption of automobile power, saved energy consumption, simultaneously, utilize residual heat of tail gas of automobile to do the refrigeration thermal source, reduced using waste heat from tail gas and outwards discharged, help alleviating greenhouse effects, promptly energy-conservation environmental protection again.
