Problems solved by technology

[0007] The deficiencies of existing lithium bromide refrigeration air conditioners are: 1) it is purely to drive the refrigeration unit to refrigerate with the heat energy that fuel oil or gas burns in the burner, because the combustion efficiency of fuel oil or gas is low so its cost is higher, The price is more expensive, and it will pollute the environment due to insufficient combustion during long-term combustion; 2) Regardless of the cooling capacity of the air conditioner, its absorber, evaporator and condenser must work under vacuum to ensure that the water For this reason, the absorber, evaporator and condenser must be installed in a vacuum box, which increases the investment cost of the equipment and increases the maintenance cost during use to maintain the vacuum

Embodiment 2

[0023] Embodiment 2. The lithium bromide refrigeration air conditioner driven by the multiple energy sources of this example, its structure can be obtained from figure 2 Seen in, it differs from Embodiment 1 in that its high-pressure generator 5 can also be connected with a combustion thermal energy drive assembly of fuel oil or gas, which is a combustor with a chimney 17a communicated with the high-pressure generator. device 17. It is mainly used in the refrigeration system of the central air conditioner with a large cooling capacity. In rainy days, the solar drive components are replaced by fuel or gas combustion heat drive components to perform refrigeration work. At night, the relatively rich and cheap valley electricity is used in the day, and the microwave energy is used to drive the components and use the lithium bromide refrigeration air conditioner for cooling.

[0024] In the present embodiment, because the refrigerating capacity of central air conditioner is bigge...

It features the high pressure generator connected to the solar energy driving assembly comprising solar heat collector, solar heat accumulator and heat pump, and the microwave energy driving assembly comprising magnetron set on the high pressure generator, ultrasonic solid-liquid separator capable of realizing ultrasonic spraying and microwave heating and spraying pump; and the evaporator with ultrasonic evaporator for normal pressure evaporation.

Description

technical field [0001] The invention relates to a lithium bromide refrigeration air conditioner, in particular to a multi-energy drive for people to choose different energy sources in different time periods, such as combustion heat energy of gas or fuel oil, solar energy, microwave energy, etc., to drive the same lithium bromide refrigeration unit for refrigeration lithium bromide refrigeration air conditioner. Background technique [0002] With the warming of the global weather and the continuous improvement of people's living standards, air conditioners have entered thousands of households, but the existing freon-refrigerated air conditioners consume a lot of electricity, especially in the hot summer, the air conditioners occupy The electricity load can reach 40% of the total load of urban electricity, which makes the urban electricity that is in short supply even more scarce; in addition, Freon also destroys the ozone layer of the atmosphere. Therefore, a lithium bromide...
