Background

The solar water heating system has rapid development and obvious energy-saving effect, is mainly used for preparing hot water in winter in south, and wastes a large amount of resources due to incomplete use of the hot water prepared by solar energy in summer; the absorption refrigeration technology can convert waste heat into cold energy, so that the waste heat is recycled, and the aim of saving energy is fulfilled.

However, since the temperature of solar hot water is low, the single-effect lithium bromide absorption refrigerating unit can only be driven below 100 ℃, the conversion efficiency is low, and the existing double-effect lithium bromide absorption heat pump unit needs a heat source above 120 ℃ for driving, the heat exchange equipment is huge, the investment cost is high, so that the efficiency of the solar energy utilization comprehensive energy-saving system is low, the practicability is poor, and the solar energy utilization comprehensive energy-saving system is greatly limited in use occasions and environments.

Wherein the existing double-effect lithium bromide absorption refrigerating unit as the hot water refrigerating part, as shown in fig. 2, comprises: the lithium bromide dilute solution from the absorber is driven by the solution pump 208 to enter the high-temperature generator 201 and heated to boil inside to generate water vapor, the high-temperature solution enters the low-temperature generator 214 after being throttled and decompressed by the high-temperature solution U-shaped pipe 215, is heated by the water vapor from the high-temperature generator 201, continues to boil under a low-pressure state to become a solution with higher concentration, enters the absorption chamber 210 after being throttled and decompressed by the low-temperature solution U-shaped pipe 211, absorbs the water vapor from the evaporation chamber 205 and returns to the dilute solution, a circulation loop of the lithium bromide solution is formed; water vapor from the high-temperature generator 201 enters a heat exchange tube 213 of the low-temperature generator for heat exchange and condensation to form condensed water, the condensed water enters an evaporation chamber 205 through a U-shaped tube II 212 of the condensed water, a solution in the low-temperature generator 214 is heated and boiled by the heat exchange tube 213 of the low-temperature generator to generate water vapor, the water vapor enters a condensation chamber 202, the condensed water is subjected to heat exchange and condensation with cooling water in the condensation heat exchange tube 203 to form condensed water, the condensed water is throttled and depressurized through a U-shaped tube I204 of the condensed water and then enters the evaporation chamber 205, the condensed water is subjected to heat exchange with circulating water in a heat exchange tube 206 of the evaporation chamber in the evaporation.
