1. Which of the following are typical benefits of a distributed water-source heat pump system? (select all that apply)a) Limited mechanical room space is required
2. True or False: A water-source heat pump system benefits from heat recovery because heat rejected to the water loop by those heat pumps operated in the cooling mode can be extracted from the same water loop by those heat pumps operating in the heating mode.True
3. True or False: A Digital scroll compressor unloads by periodically separating the two scrolls, while the motor continues to operate.True
4. True or False: A variable-speed compressor unloads by reducing the rotational speed of the motor.True
5. True or False: A water-source heat pump that uses a variable-speed fan and variable-speed compressor benefits from improved dehumidification performance at part-load operating conditions.True
6. Which of the following are benefits of delivering conditioned outdoor air directly to each zone, rather than to the intake of each heat pump? (select all that apply)a) Easier to ensure that the required outdoor airflow reaches each zone
7. True or False: Allowing the dedicated outdoor-air system to deliver the conditioned OA at a cold temperature (rather than reheated to neutral) often provides the opportunity to downsize the local heat pumps since they do not need to provide as much cooling capacity.True
8. True or False: One of the concerns about delivering the conditioned OA at a “neutral” temperature (close to the desired space temperature) is an increased risk of overcooling the zone.True
9. True or False: ASHRAE Standard 90.1-2010 requires each water-source heat pump to be equipped with an automatic valve to shut off water flow when the compressor is off.True
10. True or False: ASHRAE Standard 90.1-2010 requires an airside economizer be designed into every water-source heat pump system.True
11. True or False: A ground-source heat pump system reduces overall system energy because it reduces the energy required to reject heat from (and add heat to) the water distribution loop.True
