But many new forms of energy exist unsettled drawback, solar energy is subject to the restriction of weather and sunrise sunset, and wind energy is subject to the impact of wind-force power, so supplementary energy is to guarantee that system stable operation plays very important effect.But the absorption heat pump that each factory produces at present substantially all utilizes the single energy, or with steam or with hot water or use combustion gas.In utilizing the absorption type heat pump system of new forms of energy, must separately establish supplementary energy.A kind of absorption heat pump of various energy resources that uses will play positive role for promoting the application of absorption heat pump and new forms of energy.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of absorption heat pump that uses various energy resources, is in operation, and can between the energy using, automatically switch according to the condition of setting, and guarantees the operation of absorption heat pump and system stability.
For solving the problems of the technologies described above, the present invention improves the generator of absorption heat pump, has increased the electric heating tube of some in generator below heating tube, and electric heating tube is immersed in the solution of generator bottom.The present invention has simultaneously set up combustion gas (or fuel oil) heater at generator heating circuit, when main thermal source can not guarantee heat supply (heat supply not enough or cannot heat supply), system will automatically start electric heater or start combustion gas (or fuel oil) heater, guarantee system stable operation.
Combustion gas (or fuel oil) heater, as a module in native system, determines whether install combustion gas (or fuel oil) module additional in machine according to user's actual conditions during fabrication.If need this supplementary energy, then determine to add combustion gas or the heater of fuel oil according to user's energy supply situation, can add very easily the auxiliary heating module that is applicable to user.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the present invention is further illustrated.
Fig. 1 is a kind of schematic diagram that uses the absorption heat pump of various energy resources of the present invention.
