Analysis of leakage influence within capillary heat pipe recuperative heat exchanger
Original language description
The paper analyses the leakage of air-to-air recovery heat exchanger consisting of 100 capillary thermal tubes 1.5 m long and aligned in ten rows. The operation of the recovery exchanger prototype was tested in a pigsty. The analysis focuses on how the exchanger leakage affects the heat utilisation efficiency of the air ducted from the pigsty, changes in supply/exhaust air flow rate ratio, supply air temperature, thermal output obtained, and exchanger's total thermal and mass balances. The differences of 2.7 - 14.5 % between the exchanger's measured and actual thermal efficiency according to relation (16) and those of 18.7 - 55.8 % between the exchanger's measured and actual running efficiency (13) increase as the ratio of supply and exhaust air mass flow rates increase.
