Absorption air conditioner

The present invention relates to an air conditioning apparatus, and more particularly to an absorption type air conditioning apparatus capable of reducing energy loss.

In general, the more conventional air-conditioning devices on the market mainly compress the refrigerant into a high-pressure and high-temperature gas state by a compressor, and there are widespread disadvantages of energy consumption. In view of this, with the advancement of technology and the rising awareness of environmental protection, the system has gradually developed towards the design of absorption air conditioners, mainly replacing the compressor with an absorber and a decomposition tank, with lithium bromide system and ammonia system as Develop the main axis to achieve energy conservation.

For example, as shown in FIG. 1 , a conventional absorption type air conditioner 9 is disclosed, which is connected by a vacuum absorption tank 91, a heating decomposition tank 92, a condenser 93 and an expansion valve 94 in sequence. In a closed loop, the pipeline is filled with circulating fluid, and the vacuum absorption tank 91 is provided with a radiator 911. Thereby, ammonia [or a solute such as lithium bromide] can be mixed with water [solvent] in the vacuum absorption tank 91 to form a binary solution, and the binary solution flows into the heating decomposition tank 92 to be heated [Q _in ]. Vaporizing high temperature gaseous ammonia; then, the high temperature gaseous ammonia flows into the condenser 93 to discharge heat ( _Qout ) to a heat storage to maintain the heat storage at a predetermined temperature; finally, the gaseous ammonia is discharged while discharging heat. After the liquid is passed through the expansion valve 94, it flows back to the vacuum absorption tank 91, and the remaining heat (q) is discharged to the outside by the radiator 911, that is, a cycle is completed.

However, in the design of the conventional absorption type air conditioner 9, since the vacuum absorption tank 91 must maintain a vacuum state by a pump so that gaseous ammonia can be dissolved in water, the vacuum is utilized by the pump.
