The pharmaceutical industry is aided by the use of HVAC systems as quality control for pharmaceutical products relies on precise control of temperature and humidity. Furthermore, many of the production procedures imply biological or biochemical reactions. These reactions only take place in strict conditions in order to achieve maximum yield. Storage of strains used for drug and medicine production must take place in very controlled conditions, typically at lower temperatures. Highly sophisticated refrigeration systems are used in order to control and adjust precise temperatures in rooms and storage units.
