What are the difference between package unit and split unit?

Answer 1

A package unit contains all elements of the refrigeration cycle in one system. The 4 major components include: A compressor, condenser, metering device, and a evaporator. All elements are needed to complete the cycle of refrigeration.

As for a split unit, All elements of the refrigeration cycle are used, however the condenser is located outside of the facility, while the evaporator is located inside of the facility.

To better understand the difference in question, you must understand the job of each component in the refrigeration cycle. For example, a condenser is normally used to reject heat or cold air from a building, while a evaporator normally supplies heat or cold air to the building.

Answer 2

A package unit contains all components in a single outdoor unit, making it easier to install and maintain. A split unit has separate indoor and outdoor units connected by refrigerant lines, providing more flexibility in placement and zoning control. Package units are typically used in commercial settings, while split units are more common in residential applications.
