Portable split air conditioners, also known as portable mini-split air conditioners, do exist, but they are not as common as traditional portable air conditioners or standard split systems. The reason for their relatively limited popularity can be attributed to a few factors and potential drawbacks:
Complex Installation: While portable split air conditioners offer some advantages of traditional split systems, they still require more complex installation than standard portable air conditioners. Installing a split AC involves mounting the indoor unit on the wall and connecting it to the outdoor unit, which requires drilling holes and running refrigerant lines. This setup can be more challenging and time-consuming than simply venting a hose out of a window or using a portable air conditioner that doesn't require outdoor installation.
Less Portability: Although they are more portable than traditional split systems, portable split air conditioners are not as mobile as standard portable AC units. Once installed, moving them to a different room can be cumbersome compared to standalone portable units that you can easily roll or carry.
Cost: Portable split air conditioners tend to be more expensive than standard portable air conditioners. The additional cost comes from the split system's components and the complexity of installation.
Performance and Efficiency: Portable split air conditioners may not offer the same level of cooling efficiency as some high-end traditional split systems or central air conditioning. The design of the portable split AC may not be as optimized for maximum cooling performance in larger spaces.
Noise: The indoor unit of a portable split AC can generate some noise, similar to a traditional split system. While it might be quieter than a portable air conditioner with an internal compressor, it might not match the noise level of a dedicated indoor unit in a standard split system.
Aesthetics: Some people may not like the appearance of an indoor unit mounted on the wall, especially if they prefer a sleeker and less obtrusive design.
Despite these drawbacks, portable split air conditioners can still be a viable option for certain situations. They can be useful in situations where you want more cooling power than a standard portable unit can provide, and where the flexibility of a portable system is desired, albeit with a bit more complexity during installation.
Before deciding on a cooling solution, it's essential to assess your specific needs, the size of the space you want to cool, and your budget to determine the most suitable air conditioning system for your requirements. Consulting with an HVAC professional can help you make an informed decision and ensure proper installation and performance.
