Description

technical field [0001] The invention relates to a high-pressure module of a compound refrigeration system driven by low-grade energy and mechanical work. Background technique [0002] At present, the key technologies for low-grade energy refrigeration and air conditioning have matured. Especially in terms of solar collectors, vacuum tube collectors and flat plate collectors have been promoted and applied in the market. In terms of refrigerators, lithium bromide absorption refrigerators entered the market in large numbers in the 1990s. Therefore, low-grade energy refrigeration is technically feasible. However, in the process of popularization, the following problems still exist: [0003] 1) The outlet temperature of the working fluid of the solar collector is low, the quality of the heat source is poor, and the quality and efficiency cannot be guaranteed at the same time. [0004] 2) The low cost performance of solar collectors also hinders its large-scale application. ...

Problems solved by technology

[0003] 1) The outlet temperature of the working fluid of the solar collector is low, the quality of the heat source is poor, and the quality and efficiency cannot be guaranteed at the same time

[0004] 2) The low cost performance of solar collectors also hinders its large-scale application

[0005] 3) The solar energy is dispersed, and the energy supply per unit area is limited

[0006] 4) The subconsciousness of consumers who pay too much attention to the initial investment cost and ignore the operating cost during the service period is difficult to change in the short term

[0007] For conventional low-grade energy, especially solar heat driven heat pumps, low efficiency of refrigeration cycles, high temperature requirements for heat sources, and difficulty in adapting to the discontinuity and instability of solar radiation itself, which have plagued the promotion of solar heat pumps and refrigeration, based on heat (cold) Quantitative Grading Principle
