There are two main ways to install multiple splits:
Conventional System (multiple condensers): Each indoor unit (evaporator) is connected to its own condenser. This increases the number of outdoor units and may require more space and energy.
Multi Split System (one condenser for multiple evaporators): A single outdoor unit serves from two to five indoor units (depending on the model and power). This is a more practical and economical solution in terms of space and external aesthetics.
Heat Load Planning
Before installation, it is essential to calculate the heat load of each room. This calculation defines the power (in BTUs) required for each room and determines the ideal model for each evaporator. The goal is to ensure energy efficiency and thermal comfort without waste.
Home Infrastructure
The installation of multiple splits requires adequate infrastructure, such as:
Compatible electrical network: each device needs an adequate circuit breaker. In multi-split systems, the electrical installation is centralized, which may require a review of the power panel.
Piping and drain: each unit needs its own copper piping and drainage system, which must be well planned to avoid visual intersections and leaks.
Strategic Location of Units
The choice of location to install the internal and external units should consider:
Good air distribution in the environment;
As little noise as possible;
Ease of access for maintenance;
Ideal distance between evaporators and condenser (especially in multi-split systems).
Advantages of Multiple Installation
Individualized comfort for each environment;
Greater energy efficiency with controlled use for each room;
Cleaner external appearance in the case of multi-split systems;
Greater property value.
Conclusion
Installing multiple splits in a home is an excellent solution for those seeking comfort and personalized air conditioning in all environments. With the help of a qualified professional, it is possible to correctly plan the system, choose between conventional split or multi split and ensure a safe, efficient and aesthetically pleasing installation.
