keskHVACsüsteem

keskHVACsüsteem, which translates to central HVAC system, refers to a unified system designed to control the heating, ventilation, and air conditioning of a building. Unlike individual window units or portable devices, a central HVAC system uses a network of ducts and vents to distribute conditioned air throughout an entire structure from a single main unit. This system typically comprises an air conditioner for cooling, a furnace or heat pump for heating, and a ventilation component to exchange indoor air with fresh outdoor air.

The core of a keskHVACsüsteem is the air handler, which houses the fan and the heat exchange components (evaporator coil for cooling, furnace or heat pump coil for heating). Air is drawn from the building through return ducts, passes through a filter to remove particulates, and then is either heated or cooled by the air handler. The conditioned air is then propelled by the fan through supply ducts to various rooms and spaces. The ventilation aspect can be integrated through fresh air intakes connected to the air handler or via separate energy recovery ventilators (ERVs) or heat recovery ventilators (HRVs). These systems are controlled by a thermostat, which monitors indoor temperature and signals the HVAC system to activate heating or cooling as needed. Regular maintenance, including filter changes and professional servicing, is crucial for the efficient and long-term operation of a keskHVACsüsteem.
