摘要

This work presents a performance comparison between several incubators models including CO2 and NH4 emission.A mathematical model for incubators carbon foot print was developed to estimate CO2 and NH4 emission.The program written by C++language including convert line.The modular structure of program consists of a main programme and series of independent subroutine:each one deals with a specific parameter of the required data.The computer programme has a wide range of applicability several values of size of the machine(NO.egg),Fertility(F),Heat production embryo(HPe),maximum CO2 level(CO2)m,CO2 level incoming air(CO2)I,RQ value(RQ)to estimate Heat production(HP),CO2 production,Ventilation(V),Ventilation of egg(Vegg)Input data:Enter size of the machine,Fertility(F),Heat production embryo(HPe),maximum CO2 level(CO2)m,CO2 level incoming air(CO2)I,RQ value(RQ)the results As the growth period passed from the first day of the twenty-first day,the amount of heat produced increased from 0.0001 to 0.35 w/egg,and ventilation from 0 to 352 m^3/hr as well as the amount of carbon dioxide produced from 0.0000158 to 0.04318 lit/hr/Mach.As the number of eggs increased from 5,000 to 30,000 eggs,each of the heat produced increased from 923.4 to 5540.4 kg/hr,the resulting carbon dioxide from 32 to 190 lit/hr/Mach,and ventilation from 9 to 54 m^3/hr.
