Ventilation and temperature. Regulation 7 of the UK''s Workplace (Health, Safety and Welfare) Regulations 1992 requires that ''during working hours, the temperature in all workplaces inside buildings shall be reasonable''. It is recommended that, in the typical workplace, the temperature should be at least 16°C unless much of the work
2006101 · Therefore, combining temperature control with ventilation control at the zone level is important for achieving thermal comfort and acceptable IAQ. However, this issue is rarely addressed in the literature. We propose a multiple-input–multiple-output (MIMO) controller based on a model predictive strategy to control dry-bulb temperature

When using piglet heaters, brooders and/or mats, comfort zones should be at 95°F (35°C) directly beneath the brooder for 14-to-21 days upon placement, dependent on pig size and health. Remember, pigs require 0.4 ft 2 of mat space to maximize pig comfort and eliminate drafting from below the slats or plastic flooring. Minimum ventilation.
2024115 · This region represents a transition climate, in which a direct ventilation system can be used to balance building internal heat gains. Therefore, no heating or cooling is needed in this region. And, the use of the multi-heat exchanger system can also achieve the independent control of temperature and humidity, and the SMER can be
