Cold working medium circulation loop, the concentrated solution in instant liquid generator also can be entered in absorber, are absorbed first by absorber and are evaporated
Steam in device is become weak solution, continues supply work.The pipeline of the solar heat water subsystem passes through the solution
Generator, can provide heat for the solution in solution generator, promote the solution in solution generator to be heated and produce steam shape
Into concentrated solution, the further work for system provides condition；And solar heat water subsystem effectively make use of solar energy source, with
Air-conditioning heat-exchange working medium cycle subsystem cooperating, can form the utilization form of various energy resources, very flexibly.The air-conditioning is changed
Hot working fluid cycle subsystem includes cross valve, compressor and subcooler, the export pipeline of the compressor and the cross valve
It is connected, and the export pipeline of the compressor, through the solution generator, solution generator can be to discharges in compressor
High-temperature high-pressure refrigerant carry out pre-cooling, facilitate the work of next step, and the solution generator to be respectively cooperating with the air-conditioning and change
Hot working fluid cycle subsystem and Absorption heat-transformer subsystem cooperation, when ensure that heat pump refrigeration or heating work
Quality, makes the functional reliability of whole system higher.The subcooler is intercoupled with first vaporizer, and states first
Vaporizer be coupled with the subcooler after device, also can either exchange heat for air-conditioning for Absorption heat-transformer subsystem work
Working medium circulation subsystem work, it is ensured that in the case of solar energy or other driving sources deficiency, Absorption heat-transformer subsystem and
Air-conditioning heat-exchange working medium cycle subsystem also can be worked simultaneously, reliably be efficiently completed refrigeration or the work for heating, and two kinds are followed
The mode that ring is coupled can make hot water temperature lower than the temperature under simple subprogram mode, so as to reduce the requirement to heat collector,
Increase substantially the COP of total system.
