The proverbial “little pig who stayed home” will be assured of good indoor environmental quality under proposed research from ASHRAE. The Society is funding research to update heat and moisture production rates from pigs and their housing facilities, which are the foundation for effective design and operation of HVAC&R systems.
“Without proper heat and moisture production values, ventilation systems will be inadequately designed and operated, resulting in unsuitable building environments for animals and workers,” said Lingying Zhao, Ph.D., Member ASHRAE, a member of ASHRAE’s technical committee on plant and animal environment, which is sponsoring the project. “Incorrect data about those values also can create potential moisture buildup that could lead to premature building failure.” The project is one of 16 currently out for bid by ASHRAE. Currently available data on heat and moisture production rates is nearly 50 years old. Over the past half-century, swine production has undergone significant changes in terms of genetic potential, nutrition, housing strategies and production systems, all of which affect swine heat and moisture production rate. New feeds, for example, can affect the heat production rate from the actions of eating, digestion, and absorption and utilization of the nutrients. The amount pigs are fed on a regular basis has changed throughout the years as has the nutrients contained in feed. Types of housing also impacts swine heat and moisture production rates. Although pigs have a few sweat glands, they mainly stay cool due to other moisture sources in their pen evaporating from their skin, according to Zhao.
