Lithium Bromide Air Conditioner and Generator Unit for Energy Storage Engine Exhaust Heat

Abstract

The invention relates to an energy-accumulating lithium bromide air conditioner using the waste heat of the tail gas of an engine and a generator unit of the lithium bromide air conditioner. An evaporation section of a low-temperature-level heat pipe of the generator unit is arranged in an exhaust pipe of the engine; a condensation section of the low-temperature-level heat pipe is arranged in a low pressure generator; the evaporation section of a high-temperature-level heat pipe is arranged in the exhaust pipe of the engine and positioned in front of the evaporation section of the low-temperature-level heat pipe; a heating condensation section of the high-temperature-level heat pipe is arranged in a high pressure generator; an energy-accumulating condensation section of the high-temperature-level heat pipe is arranged in a phase-change energy accumulator; the phase-change energy accumulator comprises a shell, in which the energy-accumulating condensation section of the high-temperature-level heat pipe is accommodated, of a phase-change heat-insulating material; compensation heat pipes are arranged in the phase-change energy accumulator and the high pressure generator; the evaporation sections of the compensation heat pipes are arranged in the phase-change heat-insulating material of the phase-change energy accumulator; the condensation sections of the compensation heat pipes are arranged in the high pressure generator; and radiating devices which are arranged in series between a steam outlet of the high pressure generator and a steam inlet of a condenser are arranged in the low pressure generator.

Description

technical field [0001] The invention relates to a lithium bromide air conditioner which utilizes waste heat carried in engine exhaust gas as a heat source, and at the same time, the invention also relates to a generator unit of the lithium bromide air conditioner. Background technique [0002] With the development of my country's automobile industry, the energy consumed by vehicles is increasing day by day, and the energy saving of vehicles has attracted more and more attention. However, based on the evaluation of existing internal combustion engine indicators, about 60% of the energy in fuel oil has not been effectively utilized, and most of it is discharged into the atmosphere in the form of waste heat, causing huge economic losses and serious environmental pollution. The secondary utilization of this part of waste heat has great significance for energy saving and environmental protection. [0003] Due to the compact structure of the car and the relatively small engine di...
