Abstract
The invention provides a solar energy driven single-effect and double-effect coupled lithium bromide refrigerator, which includes a solar intermediate temperature heat collector, a gas-fired boiler, a hot water storage tank, a heat collection circulating pump, a high temperature heat exchanger, a low temperature heat exchanger, a lithium bromide solution pump, an absorber, a refrigerant water circulating pump, an evaporator, a heat exchange end, an air conditioning room, an expansion valve, a cooling water circulating pump, a cooling tower, a condenser, a low pressure generator, a high pressure generator, a hot water circulating pump, a first valve, a second valve, a third valve, a fourth valve, a fifth valve, a six valve, a seventh valve and an eighth valve. The refrigerator can efficiently utilize the solar energy via switching of the single effect and the double effects of the system according to the characteristics of the solar collector system, can reduce consumption of primary energy as compared with the conventional gas-fired lithium bromide refrigerator, and is environmentally friendly.
Description
technical field [0001] The invention relates to the technical field of solar energy utilization and air conditioning, in particular to a solar-driven single-effect coupled lithium bromide refrigerator. Background technique [0002] Solar energy is a widely distributed and clean renewable energy, which is expected to play a more important role in the energy structure of the future society. Among them, using solar energy for heating, heating and cooling is an important way to realize large-scale and low-cost utilization of solar energy. In particular, with the large-scale application of solar heat collection and heating systems in recent years, the phenomenon of excess solar heat in summer is very prominent. Scholars from all over the world are actively looking for effective ways to use solar energy for air conditioning and cooling in summer, with the purpose of improving solar energy collection. On the other hand, it can open up a new technical way to use solar energy to sol...
