Air cycle coupled with an absorption refrigerator for the indoor air conditioning.

Author(s) : BRUNELLI U., PANASITI E., PIAZZA V., et al.

Summary

The use of the air as refrigerant gas in a closed Brayton-Joule inverse cycle, besides the cooling effect produced, makes a quantity of energy available, if opportunely used, it can increase notably the plant efficiency. In this paper the authors consider the indoor air climatization, the possibility to join the air cycle to an absorption refrigerator. The energy available along the superior isobar of the air cycle can be exploited in an absorber. Therefore the necessary energy for the climatization would be produced from the air cycle and the absorption refrigerator. For the introduced solution, possible schemes of plant are proposed using values of pressures and temperatures of the air cycle in according with a commercial absorber refrigerator. Therefore, the energetic outputs of the supposed plants will be appraised and also the plant efficiency will be calculated. Such coefficient is defined as the ratio among the sum of the power produced (from the air cycle and the absorption cycle) and the electric power supplied.
