In a preferred embodiment of the present invention, it should be noted by those skilled in the art that the air compressor body and the like to which the present invention relates can be regarded as the prior art.
Preferred embodiments.
The invention discloses a multi-heat source linkage type air compressor unit, which is used for improving the waste heat generation efficiency of the air compressor unit and comprises a first heat source input module, a second heat source input module, a third heat source input module, an air compressor body and a waste heat recovery module, wherein:
the first heat source input module is selected when the ambient temperature is in a first temperature interval, so that the first heat source input module is used as an input heat source to be transmitted to the air compressor body;
the second heat source input module is selected when the ambient temperature is in a second temperature interval, so that the second heat source input module is used as an input heat source to be transmitted to the air compressor body;
the third heat source input module is selected when the ambient temperature is in a third temperature interval, so that the third heat source input module is used as an input heat source to be transmitted to the air compressor body;
and the waste heat recovery module recovers heat generated by the air compressor body.
Specifically, when the first heat source input module (air) is used as an input heat source, the air compressor body and the waste heat recovery module perform a first heat exchange process, wherein:
the air compressor body directly compresses air input by the first heat source input module, so that generated first heat is recovered by the waste heat recovery module, and the efficiency detection module detects the efficiency of the first heat exchange treatment so as to transmit generated first heat efficiency data to the background management module.
More specifically, when the second heat source input module (air and water) is used as an input heat source, the air compressor body and the waste heat recovery module perform a second heat exchange process in which:
the air compressor body directly compresses air input by the second heat source input module, so that part of generated second heat is recovered by the waste heat recovery module, and the other part of generated second heat is absorbed by water stored in the second heat source input module, so that the heated water in the second heat source input module exchanges heat with the input air, and the air body compresses the air exchanged with water in the subsequent second heat exchange treatment process;
the efficiency detection module detects the efficiency of the second heat exchange process, so as to transmit the generated second heat efficiency data to the background management module, the background management module performs simulation calculation after receiving the second heat efficiency data, so as to obtain related data of the optimal efficiency in the second heat exchange process at the current temperature, and transmits the related data to the air compressor body, so that the air compressor body adjusts the distribution condition of the second heat according to the related data (the optimal distribution of the water absorption of the generated second heat is recovered by the waste heat recovery module for part of the generated second heat and the other part of the generated second heat is stored in the second heat source input module).
It should be noted that, when the temperature is low, if air is directly used as the input heat source like the first heat source input module, the heat generated by compressing the cooler air is greatly lost, so that the heat provided in the waste heat recovery module is reduced, therefore, the heat generated by compressing the air is partially transmitted to the water in the storage device of the second heat source input module firstly, so that the water is heated, and the heated water heats the cold air input in the second heat source input module again, so that a closed loop heat exchange process is formed in the second heat source input module, and finally, the temperature of the input air can reach the maximum waste heat efficiency through distributing the second heat.
Further, when a third heat source input module (air, oil) is used as an input heat source, the air compressor body and the waste heat recovery module perform a third heat exchange process, wherein:
the air compressor body directly compresses air input by the third heat source input module, so that part of generated third heat is recovered by the waste heat recovery module, and the other part of generated third heat is absorbed by oil stored in the third heat source input module, so that heated oil in the third heat source input module exchanges heat with the input air, and the air body compresses air exchanged with the oil in the subsequent third heat exchange treatment process;
the efficiency detection module detects the efficiency of the third heat exchange process, so as to transmit the generated third heat efficiency data to the background management module, the background management module performs simulation calculation after receiving the third heat efficiency data, so as to obtain related data of the optimal efficiency in the third heat exchange process at the current temperature, and transmits the related data to the air compressor body, so that the air compressor body adjusts the distribution condition of the third heat according to the related data (the optimal distribution of oil absorption of part of the generated third heat is recovered by the waste heat recovery module and the other part of the generated third heat is stored in the third heat source input module).
It should be noted that, when the temperature of the input heat source in the third heat source input module is lower (between the first temperature interval and the second temperature interval), if the air is directly used as the input heat source, the heat generated by compressing the colder air is greatly lost, so that the heat provided in the waste heat recovery module is reduced, but the temperature is not lower than the second temperature interval, the specific heat capacity of the oil is lower than that of the water, and the heat exchange can be performed faster than that of the water, so that the heat generated by compressing the air is partially transmitted to the oil in the storage device of the third heat source input module firstly, so that the oil is heated, and then the heated oil heats the input cold air in the third heat source input module again, so that a closed loop heat exchange process is formed in the third heat source input module, and finally, the temperature of the input air can reach the maximum waste heat efficiency through distributing the third heat.
Still further, the multi-heat source linkage air compressor unit further comprises a driving selection module, wherein the driving selection module is respectively linked with the first heat source input module, the second heat source input module and the third heat source input module, so that the driving module drives the corresponding heat source to the air compressor body according to the ambient temperature.
It should be noted that technical features such as the air compressor body related to the present application should be regarded as the prior art, and specific structures, working principles, and control modes and spatial arrangement modes possibly related to the technical features should be selected conventionally in the art, and should not be regarded as the invention point of the present application, and the present application is not further specifically developed in detail.
