An air-handling system is being designed for a 40 ft 3 40

Chapter 12, Problem 12.12D

(choose chapter or problem)

An air-handling system is being designed for a 40 ft X 40 ft X 8 ft biological research facility that houses 3000 laboratory mice. The indoor conditions must be maintained at \(75^{\circ} \mathrm{F}\), 60% relative humidity when the outdoor air conditions are \(90^{\circ} \mathrm{F}\), 70% relative humidity. Develop a preliminary design of an air-conditioning and distribution system that satisfies National Institutes of Health (NIH) standards for animal facilities. Assume a biological safety level of one (BSL-1), and that two-thirds of the floor space is devoted to animal care. Since an interruption in ventilation or air conditioning could place the laboratory animals under stress and compromise the research under way in the facility, account for redundancy in your design.
