Split-type chillers and packaged chillers differ significantly in terms of structure, installation, and application scenarios. Below are the key distinctions:

| Type | Split type Chiller | Packaged Chiller |
| Structural Design |
Separated structure: divided into indoor unit (evaporator part) and outdoor unit (condenser + compressor part), connected by pipes.
High flexibility: can be arranged separately according to site conditions, such as condenser on the roof and evaporator in the machine room.
Strong customization: can adapt to different heat dissipation methods. |
Integrated structure: all components (compressor, condenser, evaporator, control system) are integrated in one box.
Compactness: small footprint, suitable for places with limited space.
Factory pre-installed: pipelines and circuits have been debugged and easy to install. |
| Installation and maintenance |
Complex installation: refrigerant pipes and power lines need to be connected on site, professional team operation is required, and the installation cost is high.
Flexible maintenance: a certain part can be inspected separately (such as replacing the outdoor unit fan), but the sealing of the connecting pipes needs to be checked. |
Plug and play: only need to connect water and electricity to operate, short installation cycle.
Centralized maintenance: All components are in one box, but the compact space may increase the difficulty of maintenance. |
| Performance and efficiency |
Heat dissipation advantage: The condenser can be far away from the heat source (such as a high-temperature machine room), with better heat dissipation conditions and more stable efficiency.
Long-distance attenuation: Too long refrigerant pipelines may lead to reduced efficiency and need to be reasonably designed. |
Stability: After overall testing before leaving the factory, the operation matching degree is higher.
Environmental restrictions: Condenser heat dissipation is affected by the installation location (such as poor ventilation may lead to reduced efficiency). |
| Applications |
High power demand (such as large shopping malls, factories).
Scenarios where the installation space is scattered or long-distance heat dissipation is required (such as high-rise buildings). |
Small and medium-sized projects (such as small office buildings, data center modules).
Rapid deployment requirements (such as temporary facilities, renovation projects). |
| Cost comparison | The initial installation cost is high (pipes, labor), but it may be more energy-efficient in the long run. | low purchase cost and installation cost, but there are fewer high-power models to choose from. |
