Description

Adsorption heat pump refrigeration power supply method

Technical field

The invention relates to a method for power supply, belonging to the technical field of thermal power.

Background technique

In general steam-type power output devices (steam engines, steam turbines), the thermal efficiency of steam expansion work is affected by the initial temperature, initial pressure, exhaust steam temperature, and exhaust steam pressure.

When the initial temperature is constant, the higher the temperature difference, the higher the efficiency. The higher the initial pressure, the higher the efficiency. When the initial temperature is constant, the lower the exhaust steam temperature, the higher the efficiency; the lower the exhaust steam pressure, the higher the efficiency.

Since the expansion of the steam power plant produces a flood, it is necessary to condense the flood into a working fluid to allow the cycle to proceed. Therefore, the steam exhaust temperature of the steam power unit generally needs to be higher than the ambient temperature. In addition, to increase the initial temperature of the steam power plant, the pressure must be increased. The pressure increase is more demanding on the pressure design of the steam power machine, and the space for increasing the initial temperature of the steam is also small. Therefore, there is little room for further improvement in the efficiency of the steam power plant.

Secondly, since the low-grade heat source cannot provide a high initial temperature, the exhaust steam temperature must be higher than the ambient temperature. The steam-powered mechanical low-grade heat source has low efficiency and low practical value.

Summary of the invention

It is an object of the present invention to provide a more efficient power supply method. The problem to be solved is to further increase the initial temperature of the steam power plant or reduce the exhaust steam temperature.

The agent is filled with an adsorbent of an unadsorbed working medium in the second adsorbent bed. Heat source Heating the first adsorption bed to desorb the working fluid in the first adsorption bed, and using the direct expansion method, the working fluid vapor desorbed by the first adsorption bed is directly expanded in the first expander to work and decompress, The pan-vapor discharged from the first expander is evaporated by the evaporator to evaporate, so that the refrigerant liquid therein is evaporated into low-pressure steam, and the low-pressure steam enters the second adsorbent bed to adsorb heat.

The effect of the invention is that the first adsorbent bed is heated by a heat source, and the working fluid vapor desorbed by the first adsorbent bed is directly expanded and worked under pressure in the first expander, and the first expander discharges the steam. The evaporator vaporizes through the evaporator, and the low pressure steam enters the second adsorption bed for adsorption. Since the second adsorbent bed can adsorb low-pressure working fluid vapor which is much lower than its temperature, the exhaust steam temperature of the present invention can be lower than the ambient temperature, and the exhaust steam temperature is lowered, thereby improving the efficiency of the steam power plant.
