Abstract

The survey comprised examination of relevant theoretical data concerning livestock ventilation together with heat recovery tests and tests with ventilation units in climate-controlled livestock buildings, in which existing units were rebuilt or replaced with new modern types, for examination of electricity saving possibilities. Moreover, considerations were made on existing research requirements within the field. It was concluded that electricity consumption for heating and ventilation purposes can be reduced by 30-60%, when using modern ventilation units, and if the humidity control unit is adjusted in accordance with seasonal weather variations. Control units used for livestock ventilation units are not equally applicable for control of the indoor climate, which may result in inexpedient temperature and humidity fluctuations. Heat recovery of ventilation air can be made in climate-controlled livestock units over a 2-5 years refund period. Well-maintained heat exchangers influence the indoor climate positively. Development of energy-control in climate-controlled buildings for piglets is needed, using methods for calculating annual energy consumption under given conditions for given ventilation and heating units or methods for evaluation of the coherence between stability of the indoor climate, managerial economics and pig growth. As the degree-day method is inapplicable, a method for correction of test data from livestock  More>>
