Energy Consumption and Indoor Environment of Broiler Houses with Energy Recovery Ventilators
We investigated the applicability of energy recovery ventilators (ERVs) in chicken broiler houses. Indoor environmental conditions and energy consumption were measured and compared in two identical broiler houses with and without energy recovery ventilators. The broiler houses used in the study were typical chick buildings in Korea constructed with concrete blocks, and are located in Iksan in the Southwestern part of the Korean peninsula. Experiments were conducted for one month during the winter season of 2008. Measurements were made continuously to collect indoor and outdoor temperature, relative humidity, ventilation rates, energy consumption, and feed water consumption over the entire period of breeding. In order to provide the same experimental conditions between buildings, the total ventilation rates were maintained equally in both houses. Our results indicated a 55% reduction in total heating energy consumption. This significant reduction is believed to be possible because the ventilation load occupied a great portion of the total heating load. Temperature uniformity was improved in the house with the ERVs, as both temporal and spatial temperature variations were reduced by continuous recirculation of indoor air by the ERVs. Further research should be conducted to optimize the ventilation system design and the operation protocols to minimize the overall energy consumptions according to the climatic conditions.
