Air Conditioning System - Sistemul de AC

Air conditioning systems are divided into three types as followed:

Individual Systems.

Unitary Packaged Systems.

Central (Hydronic) Systems.

use a self-contained , factory-made air conditioner to serve one or two rooms (e.g. room/ window air conditioner and split-type units).

It uses vapor compression cycle directly to cool the indoor air for small loads.

similar in nature to individual systems but serve more rooms or even more than one floor, have an air system consisting of fans, coils, filters, ductwork and outlets (e.g. in small restaurants, small shops and small cold storage rooms).

Basically consists of three major parts:

Air system – air handling units (AHU), air distribution (air duct) system and terminals.

Water system – chilled water system, hot water system, condenser water system.

Central plant – refrigeration (chiller) plant, boiler plant.

Air Handling Units (AHU)

Air Distribution System (Air Duct)

Ducts are used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air. These needed airflows include, for example, supply air, return air, and exhaust air.
