Refrigeration Plant Operator B Practice Test

What system is frequently used in hotels and motels for its space efficiency and individual zone control?

1. A variable volume system with perimeter heating

2. An induction system

3. A fan coil unit with make up air system

4. A hydronic heat pump system

The correct answer is: A fan coil unit with make up air system

The fan coil unit with make-up air system is particularly suited for hotels and motels due to its ability to efficiently control the temperature in individual rooms while minimizing space requirements. This system operates by circulating water or refrigerant through coils, allowing for localized heating or cooling without needing extensive ductwork. This capability is essential in hospitality environments where guest comfort is paramount, as it allows each room to maintain a tailored climate based on individual preferences. Furthermore, the inclusion of a make-up air system ensures that fresh air is introduced to the rooms, contributing to both comfort and air quality. This is crucial in settings where high occupancy might lead to a stagnation of indoor air quality. In contrast, the other systems may not offer the same level of individual room control or space efficiency. For example, a variable volume system with perimeter heating might require more extensive ductwork and does not allow for easy customization in each individual space. An induction system typically relies on central air handling units, which may not provide the same localized control. A hydronic heat pump system, while efficient, may not fit the compact and flexible requirements of many motel and hotel setups as effectively as a fan coil unit system does.
