這篇在講有關實驗用小型豬Sinclair's facilities are designed to be good to the environmentAnimal production facilities, as most commercial facilities, are typically significant users of energy due to the large number of air movements required to maintain the air quality in the animal rooms. Sinclair has implemented a number of environmentally conscious strategies to minimize the energy expenditure and improve the comfort of the animals. Energy Recovery Units: The single most significant energy reduction strategy is the introduction of energy recovery units (ERU) in the exhaust air stream. The ERUs recover the energy residing in the exhausted air expelled from the animal rooms and transfer this energy in the incoming or outside air stream, thus, preconditioning the fresh air prior to being introduced in the animal rooms. The ERUs use the building exhaust air to precool and dry the incoming hot and humid outside fresh air or preheat and humidify the incoming cold and dry outside fresh air. This drastically reduces the energy consumption of the entire HVAC system. Sinclair is using two different types of ERUs, namely the desiccant wheel or the plate type exchangers. Energy recovery is maximized by utilizing an enthalpy wheel as the heat exchanger. This device transfers sensible and latent energy between the exhaust and outside air streams, and provides substantially more heat exchange than any other type of heat exchanger. The enthalpy wheels used at Sinclair have an efficiency up to 82%. The plate type exchangers are still recovering up to 65% of the otherwise disposed energy. In other words, a plate exchanger can cool (or heat) the outside air approximately 65% of the difference between the outside air and the exhaust air. The energy savings come from the reduction of the cooling or heating load. A much smaller HVAC system can be used to make up the difference. The energy consumed by the ERU is far less than the energy saved.
