Lithium bromide absorptive refrigeration air conditioner and sanitary hot water system driven by solar energy

Abstract

The invention discloses a lithium bromide absorptive cold and hot water air-conditioner system directly driven by solar energy, which comprises an absorptive refrigeration system (200) and a chilled water energy storage loop (300), wherein the absorptive refrigeration system (200) is connected with the chilled water energy storage loop (300); and the air-condition system also comprises a solar heat collection system (100) which is connected with the absorptive refrigeration system (200). According to the cold and hot water air-conditioner system, a solar heat collection system is additionallyused as a heat source for enabling the unit to work normally at the same time of preserving the original heat source loop as an auxiliary drive heat source loop of the absorptive refrigeration system, and all loop structures of the absorptive refrigeration system are properly adjusted. The air-conditioner system has the advantages that: the solar heat collection system which integrates a solar heat collector and a high-temperature generator is adopted in the system, so that the refrigerating system is changed from a lithium bromide dual-effect absorptive refrigerating system to a lithium bromide triple-effect absorptive refrigeration system under the condition of not improving the temperature of the heat source, and the thermodynamic coefficient of the system is greatly increased, therefore the initial investment is reduced.

Description

【Technical field】 [0001] The invention relates to the field of solar energy, in particular to an economical solar-driven lithium bromide absorption refrigeration air conditioner and an integrated system for uninterrupted supply of sanitary hot water in all seasons. 【Background technique】 [0002] At present, solar energy utilization is mainly concentrated in more mature fields such as heating in winter and hot water supply in four seasons, but solar thermal utilization does not match the seasons very well. When the winter is cold and solar energy is needed, the solar radiation intensity is often not high enough. Intensity is high and the need for hot water is low. Solar air-conditioning refrigeration is obviously the best solution for the effective use of solar energy in summer. The biggest feature of solar air-conditioning refrigeration is that it matches well with the seasons. The better the sun in summer and the hotter the weather, the greater the cooling capacity of the ...

Problems solved by technology

In this way, although the heat required to obtain the unit cooling capacity has been reduced, it is necessary to use solar energy to obtain hot water above 150°C for driving the double-effect lithium bromide absorption refrigeration unit, which not only has low heat collection efficiency, high technical difficulty and high cost, but also high temperature. High-voltage solar thermal collection systems are also extremely unsafe
