Abstract

The invention discloses a mass recovery type adsorption refrigeration air-conditioning system on the basis of phase-change heat storage. The mass recovery type adsorption refrigeration air-conditioning system comprises a phase-change heat storage and exchange device, a continuous mass recovery type solid adsorption refrigeration system and a cooling water circulating system. The phase-change heat storage and exchange device comprises a plurality of rows of coiled pipes, heat-conducting media and phase-change heat storage materials, and the multiple rows of coiled pipes are arranged parallelly; the continuous mass recovery type solid adsorption refrigeration system comprises double adsorption beds, a condenser, a throttle valve, an evaporator, a reverser and a mass transfer pipeline; the reverser realizes connecting and reversing effects for the double adsorption beds, the condenser, the throttle valve and the evaporator; the cooling water circulating system comprises a cooling water tank, a circulating water pump, a radiator and circulating working media. The mass recovery type adsorption refrigeration air-conditioning system has the advantages that waste heat of cooling water of an engine is stored by the phase-change materials and can be used for driving the adsorption refrigeration air-conditioning system, accordingly, an air conditioner can continue running after parking in outdoor high-temperature environments in summer, the fuel utilization rate can be greatly increased, and ideas of energy conservation and environmental protection can be practiced while suitable interior environments of vehicles are created.

Description

technical field [0001] The invention relates to a retrograde adsorption refrigeration air-conditioning system based on phase-change heat storage, which belongs to the technical field of automobile air-conditioning. Background technique [0002] Studies have shown that the highest efficiency of a car engine can only reach 49%, and at least 51% of the energy is converted into waste heat. In this part of waste heat, 30% is discharged out of the car in the form of high-temperature exhaust gas, and 70% is taken away by the engine circulating cooling water. The large amount of waste heat taken away by the circulating water is the root cause of the overheating of the automobile cooling water tank, which not only affects the performance of the engine, but also causes a serious waste of energy, which violates the purpose of energy conservation and environmental protection. [0003] In summer, especially in the case of exposure to sunlight, the temperature of the panel under the wind...
