TUBULAR RECUPERATOR WITH A SOLAR COLLECTOR FOR RECOVERY OF HEAT FROM POULTRY HOUSE EXHAUST AIR
Wac│aw Bieda, Jan Rado˝, Eugeniusz Herbut
Results of long-term operating tests on a prototype tube-within-tube recuperator designed for recovery of heat from broiler house exhaust air are presented. The construction and operation of the recuperator accounts for specific conditions of the poultry house, such as very high dustiness and humidity of air. Two-year tests of the recuperator in real operating conditions of a typical broiler house for 16,000-18,000 chickens showed that its energy efficiency is 30-37% and it can be used over the entire production cycle of 42-45 days without the need to remove the dust deposited on the exhaust channel walls. The results of microbiological tests give no indication that the recuperator might pose a threat to biosafety of the broiler house after the 2-year operation. The results of comparative studies on basic parameters of microclimate and production efficiency in the experimental and control part of the broiler house showed that the recuperator's operation was beneficial for the energy management and production results.
Key words: recuperator, recovery of ventilation heat, acquisition of solar radiation, broiler house, microclimate.
