Inverters for controlling variables in HVAC-R systems
Good management of measurement and control of process variables in an HVAC system is essential because it provides technical benefits as well as considerable returns on investment.
Accurate measurement, rapid response, efficiency, and advanced control are fundamental tasks of products with high technology content. They improve the Life Cycle Cost of systems and guarantee correct operation of the entire process.
In an HVAC-R (Heat - Ventilation - Air - Conditioning & Refrigeration) system, good management of measurement and control of process variables is fundamental for economic sustainability and system efficiency.
In this field, control valves (despite their known disadvantages) are still used to manage flows. Using these devices with a motor whose speed can’t be controlled and that always runs at 100% causes the valves and mechanical parts to age quickly, with consequent loss of system efficiency.
