Natural Ventilation to Manage Ammonia Concentration and Temperature in a Rabbit Barn in Central Mexico

“…However, according to the objective set in this work, ammonium levels have been observed distributed mainly in the cage area as a function of the wind direction with respect to the farm. It stands out that although it is true that a difference is observed with respect to the simulated wind direction, the difference in ammonium concentration ranges from 2 ppm (Figure 7), so there is a relationship with the results found by Ngwabie et al [1], Mondaca et al [19], Flores-Velázquez et al [27], and Jin et al [28] regarding the variables that influence the concentration of gases and their interaction with the ventilation rate and temperature. cage area as a function of the wind direction with respect to the farm.…”

“…Among the research studies that have been carried out using computational fluid dynamics are the following: in pig farms, air velocity analysis [11,12], temperature and heat stress studies [13,14], studies of ammonia emissions [15,16], and those focused on dust generation within the installations [3]; in cattle facilities, studies of heat transfer [17,18], ventilation rate [19], and extensive studies on air velocity and its influence on temperature, humidity, and heat transfer [20], as well as studies on the emissions of gases such as methane and ammonia, as well as CO 2 and N 2 O [1,7]; in bird houses, there have been studies that model the indoor climate and heat emissions [21][22][23] and simulations on air flow, temperature, humidity, and ammonia emissions [24][25][26]. However, in rabbit farms there have been few studies: one study performing simulations to determine the temperature gradient and ammonia concentration [27], and a study on the distribution of the air flow of the indoor environment in a rabbit facility [28].…”
