“…To determine the design cooling load for the AC system, heat produced (HP) by the birds and their THI is required. Pedersen (2000) [43,44] model is used to calculate the HP (sensible and latent) per bird for climatic conditions of Multan. Figure 5 represents an illustration of integration of EC systems into a poultry house and sensible and latent heat load generated by a poultry bird.…”

Investigating Applicability of Evaporative Cooling Systems for Thermal Comfort of Poultry Birds in Pakistan

In the 21st century, the poultry sector is a vital concern for the developing economies including Pakistan. The summer conditions of the city of Multan (Pakistan) are not comfortable for poultry birds. Conventionally, swamp coolers are used in the poultry sheds/houses of the city, which are not efficient enough, whereas compressor-based systems are not economical. Therefore, this study is aimed to explore a low-cost air-conditioning (AC) option from the viewpoint of heat stress in poultry birds. In this regard, the study investigates the applicability of three evaporative cooling (EC) options, i.e., direct EC (DEC), indirect EC (IEC), and Maisotsenko-cycle EC (MEC). Performance of the EC systems is investigated using wet-bulb effectiveness (WBE) for the climatic conditions of Multan. Heat stress is investigated as a function of poultry weight. Thermal comfort of the poultry birds is calculated in terms of temperature-humidity index (THI) corresponding to the ambient and output conditions. The heat production from the poultry birds is calculated using the Pederson model (available in the literature) at various temperatures. The results indicate a maximum temperature gradient of 10.2 °C (MEC system), 9 °C (DEC system), and 6.5 °C (IEC systems) is achieved. However, in the monsoon/rainfall season, the performance of the EC systems is significantly reduced due to higher relative humidity in ambient air.

Poultry sector is a major contributor in GDP of Pakistan. Poultry birds are highly sensitive to ambient temperature and relative humidity. At higher temperature and humidity ranges, poultry birds face heat stroke and suffocation. Thereby, a dedicated air-conditioning system for poultry birds is mandatory. In this regard, performance of low-cost desiccant dehumidification system coupled with Maisotsenko cycle evaporative cooling (M-DAC) system is experimentally analyzed for potential application of poultry birds air-conditioning. Thermodynamic performance of M-DAC system is analyzed in terms of slope (i.e. ϕ*=0.22) and effectiveness (ε). Thermal comfort of poultry birds in terms of temperature humidity index (THI) is assessed using ambient data of Multan (Pakistan) and process air conditions. M-DAC system was found to be effective (in terms of THI) for poultry birds air-conditioning around the year especially in hot summer months (i.e. May, June July, August, and September) when THI for ambient air exceeded beyond permissible limit.

“…Steady-state models are less complex than dynamic ones and usually adopt longer simulation time steps. The steady-state models considered in the framework of this review, in fact, adopt simulation time steps that go from 30 min [67] to two hours [65]. Usually, steady-state models are based on static equations that describe the steady-state thermal balance of the livestock house.…”

The need to improve the sustainability of intensive livestock farming has led to an increasing adoption of Building Energy Simulation (BES) models for livestock houses. However, a consolidated body of knowledge specifically dedicated to these models is lacking in literature. This gap represents a significant obstacle to their widespread application and scalability in research and industry. The aim of this work is to pave the way for scaling the adoption of BES models for livestock houses by providing a comprehensive analysis of their application, development, and validation. For this aim, a systematic review of 42 papers—selected from over 795 results from the initial database query—is carried out. The findings underscored a growing body of research that involves BES models for different purposes. However, a common approach in both model development and validation is still lacking. This issue could hinder their scalability as a standard practice, especially in industry, also considering the limitations of BES models highlighted in this work. This review could represent a solid background for future research since provides an up-to-date framework on BES models for livestock houses and identifies future research opportunities. Moreover, it contributes to increasing the reliability of BES models for livestock houses by providing some recommendations for their validation.
