agregaty

Agregat is a Polish noun used in technical and everyday language to denote a unit that consolidates components or performs a specific function. It is a polysemous term with several common senses, including power generation, climate control, and material composition. In practice, agregat often describes a self-contained machine or a grouped system rather than a loose collection of parts.

One prevalent sense is generator set, or agregat prądotwórczy. This device combines an internal combustion engine with an electrical generator to produce electricity. They appear as portable or stationary units and are powered by diesel or gasoline, with output rated in kilowatts or kilovolt-amperes. Applications include backup power for buildings, construction sites, remote facilities, and events. Key considerations include fuel type, noise, emissions, cooling, and maintenance.

Another sense is an aggregate in construction: a material composed of particles such as sand, gravel, or crushed stone used in concrete, asphalt, or roadbeds. Properties like size distribution, cleanliness, hardness, and moisture influence strength and durability. Aggregates can be natural or manufactured and are often graded to meet performance targets.

The term is also used for self-contained subsystems within larger equipment, such as cooling aggregates or air conditioning units, providing a single function within a broader machine.

Because agregat is polysemous, its meaning depends on context, and English translations may use generator set, aggregate, or module.
