Variable Air Volume (VAV)
The VAV system has a central air-processing unit to produce air at a specified temperature and relative humidity. The conditioned air from the main unit is conveyed in ductwork to ceiling diffusers which incorporate thermostatically controlled actuators. These can change the air volume to suit each room load. In a large room, several of these VAV ceiling units may be controlled by one room thermostat.
Umidificatore
Depending on the state of the air on entering a spray washer, it can be humidified or dehumidified. Humidification in the presence of moisture is understandable, but dehumidification is less easy to comprehend. It occurs when the spray is at a lower temperature than the air and the dew point of the air.
Chilled Beams And Ceilings
Chilled beams and chilled ceilings require a relatively modest cooling water temperature (14–17°C), which can be obtained using natural cold water storage or free cooling from outside air over periods of the year depending on climate.
Two-Way Control Valves
The control valve is possibly the most important component of a fluid distribution system because it regulates the flow of fluid to the process under control. In HVAC systems, control valves are primarily used to control the flow of chilled water, hot water, and condenser water, the subject of this section.

Raffreddamento a liquido diretto su chip: il futuro della gestione termica dei data center ad alta densità
Data center power densities have surged to 12-30 kW per rack, making liquid cooling essential. Learn how single-phase and two-phase direct-to-chip systems work, refrigerant selection criteria, and critical design considerations for hoses, tubing, and couplings in modern high-density data centers.
Diagrammi di controllo HVAC
In questo post del blog introdurremo alcuni dei diagrammi di controllo HVAC più comuni. Forniremo inoltre una breve spiegazione di ciascun diagramma e di come i suoi componenti interagiscono. Gli schemi di controllo HVAC sono strumenti essenziali per la progettazione, l'installazione e la manutenzione dei sistemi HVAC. Forniscono una rappresentazione visiva dei componenti del sistema, di come sono interconnessi e di come sono controllati. Queste informazioni possono essere utilizzate per risolvere problemi, ottimizzare le prestazioni e prendere decisioni informate sugli aggiornamenti del sistema.
