What type of fan pushes air through coils in a refrigeration system?

In a refrigeration system, a fan is used to circulate air to efficiently transfer heat through the coils. The type of fan that is commonly employed for this purpose is a forced fan. This fan actively moves air across the coils, which helps in enhancing the heat exchange process. By forcing air through the coils, it increases the rate of cooling, ensuring that the refrigerant inside the coils can absorb heat from the surrounding environment effectively.

Natural fans, as the name suggests, rely on natural airflow without mechanical assistance, which would not provide the consistent airflow needed in a refrigeration system. Exhaust fans are designed to remove air from a space rather than push air through coils. Centrifugal fans, while they can be used in refrigeration systems, are a specific type of forced fan that uses a different mechanism to move air, focusing on applications that specifically require high pressure. Therefore, describing the fan that pushes air through coils as a forced fan accurately captures its function in maintaining efficient cooling within the system.
