I've been reading that Chillers are preferred for larger buildings while DX units are preferred for the conditioning of smaller spaces. I can't understand why since I've seen that manufacturers do manufacture smaller chillers (<10 tons)
Chillers are not commonly used for smaller buildings because they are designed for large-scale cooling needs. Smaller buildings typically have lower cooling demands that can be met by alternative, more cost-effective systems such as window air conditioners or split systems.
Yes, chillers can technically be used in smaller buildings, but they are not typically the most practical or efficient solution. They require a large amount of space, energy, and maintenance, which can be excessive for the cooling needs of smaller buildings.
The main drawbacks of using chillers in smaller buildings are the high cost of installation and operation, the need for regular maintenance and repairs, the large amount of space they require, and the energy inefficiency for lower cooling demands.
In some cases, using a chiller in a smaller building may provide more precise temperature control and a longer lifespan compared to other cooling systems. However, these benefits may not outweigh the drawbacks and cost for most smaller buildings.
Alternative cooling systems for smaller buildings include window air conditioners, split systems, packaged units, and variable refrigerant flow (VRF) systems. These systems are more cost-effective and efficient for smaller cooling needs compared to chillers.
