Process method and device for refrigeration, heating and water supply by utilizing solar energy

Abstract

The invention discloses a device and a process method thereof for refrigeration, heating and water supply by utilizing solar energy, which belongs to the field of solar optothermal utilization. A solar thermal collector is installed on a roof of a building, and temperature differential circulation between a solar thermal collection system and thermal storage water tanks is realized through temperature differential circulating pumps, pipelines and plate-type heat exchangers, so that the temperature of the thermal storage water tanks is maintained within a certain range to satisfy requirements. One thermal storage water tank is arranged and used for driving a lithium bromide absorption refrigerating machine and a heating heat medium water source; the other thermal storage water tank is arranged and used as a domestic hot water heat source and for preventing the overheating of the previous thermal storage water tank. Through the device, the solar energy can be fully utilized to provide refrigeration or heating and living hot water in summer or winter, and the device is reliable in operation, completely realizes intellectualized control, is environment-friendly and energy-saving and realizes the integrated organic combination of refrigeration, heating, domestic hot water and building.

Description

technical field [0001] The invention belongs to the technical field of solar thermal utilization, and in particular relates to a process method and a device for utilizing solar energy for cooling, heating and water supply. Background technique [0002] With the development of the economy and the improvement of people's living standards, the proportion of air conditioning, heating and domestic hot water energy consumption in my country's building energy consumption has increased significantly, and gradually developed into a major part of building energy consumption, bringing energy and environment. Come more pressure. Solar energy is an inexhaustible clean energy source, and using solar energy to supplement conventional energy to drive air-conditioning, heating and domestic hot water systems is of great significance for energy saving and environmental protection. [0003] Due to the periodic fluctuation and instability of solar radiation when using solar energy for cooling an...

AI Technical Summary

Problems solved by technology

When the heat gain of the heat storage tank is greater than the output, the temperature of the heat storage tank will easily exceed the maximum temperature, causing the system to fail to operate. In summer, when the radiation is very good, the lithium bromide absorption refrigerator cannot operate; The temperature of the hot water tank is higher than the limited maximum temperature of the floor radiant heating medium, which causes the system to fail to start
