1.HVAC Function: The primary function of an HVAC (Heating, Ventilation, and Air Conditioning) system in a data center is to remove the excess heat generated by the equipment to prevent overheating1.

1.Heat Removal: The HVAC system should be designed to take the heat generated by the data center equipment outside. This is typically achieved through a combination of air conditioning and ventilation systems1.

1.Cool Air Supply: Simultaneously, the system must supply cool air inside to maintain the equipment at optimal operating temperatures. This is often done using chilled water systems, air conditioners, and controlled airflow management1.

1.Temperature Stability: Maintaining a stable temperature within the recommended range is crucial for the longevity and reliability of data center equipment. The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) recommends keeping data center temperatures between 64 and 81 degrees Fahrenheit2.

1.Design Considerations: Rachel should consider the layout of the data center, the heat output of the equipment, and the local climate to design an HVAC system that effectively manages the temperature1.
