Solar Composite Energy System Based on Solid Adsorption Refrigerator

technical field

The invention relates to a system in the technical field of refrigeration, in particular to a solar composite energy system based on a solid adsorption refrigerator.

Background technique

The energy issue is a major issue facing human development, and the coordinated development of energy and the environment has become a trend. The proportion of my country's building energy consumption has risen from 10% in 1978 to 27.45%, of which heating and air conditioning energy consumption accounted for 55% of the total building energy consumption. Making full use of solar energy, a green and clean energy in buildings, is of great significance to reducing building energy consumption, reducing environmental pollution, and improving energy structure, and at the same time provides a resource guarantee for improving my country's sustainable development capabilities. When the solar radiation is strong and the temperature is high, people need air conditioners to cool down rather than hot water. This situation is particularly prominent in southern my country. Therefore, it is of great significance to expand the solar water heating system and develop a solar composite energy system integrating hot water supply, heating and air conditioning. Solar water heating and floor heating technologies are relatively mature, and solar air-conditioning refrigeration has not yet made a breakthrough in industrialization. Generally, lithium bromide absorption chillers are used. The current hot water type (single-stage) absorption chillers require a heat source temperature of 88-90°C Above, the requirements for solar collectors are relatively high. It cannot be well connected with the solar water heaters generally used in the market. The effective time of running solar energy at high temperature is very short, and the temperature requirement can only be reached when the solar radiation is strong in a day, and the thermal efficiency of the solar collector will also be reduced. In addition, the system investment cost is high, and due to the capacity limitation of the lithium bromide absorption refrigerator itself (the cooling capacity of the lithium bromide absorption refrigerator with the smallest capacity is also above 70kW), there is no small-capacity unit practical for households, based on the lithium bromide absorption refrigerator The solar air-conditioning system of the refrigerator is difficult to miniaturize (capacity is as low as 10kW or less), and cannot be directly applied to the air-conditioning and refrigeration market of a large number of households. In short, the high cost and the non-universality of solar collectors have affected the popularization and application of solar absorption air conditioners.

After searching the literature of the prior art, it is found that the Chinese invention patent name is: solar energy medium and high temperature heat collection absorption type air conditioning system, and the application number is: 01251735, which discloses a kind of solar energy medium and high temperature heat collection absorption type air conditioning system. Including solar medium and high temperature heat collection devices and auxiliary boilers. The hot water in the hot water storage tank is used to drive the absorption refrigeration unit in summer, to provide heating water for air conditioners in winter, and to supply domestic hot water in four seasons. This patent is mainly aimed at absorption refrigeration units, and does not involve the application of high-efficiency adsorption refrigeration technology in solar air conditioning, nor does it include solar enhanced natural ventilation technology and solar floor heating technology.

The solar collector array heats the water in the lower part of the hot water storage tank and flows into the upper part of the hot water storage tank. When the temperature is fixed, the hot water circulation pump is turned on, and the water in the upper part of the heat storage tank is sent to the terminal heat utilization system. As the season changes, its flow direction depends on the system's working mode. If the system is in the air-conditioning mode, the hot water in the upper part of the heat storage tank is passed into the adsorption refrigerator to heat one adsorption bed to decompose, while the other adsorption bed is cooled by the cooling water provided by the cooling tower, and then absorbs the cold in the evaporator.
