Elements Of An Efficient HVAC System

Today’s installations are built to satisfy stringent standards for the climate, indoor air quality and consumers. As a result of increases in the operational performance of main device modules, much of the advances in HVAC machine output have arrived. Many benefits arise from the usage of existing current or advanced technology in the HVAC sector. Also the usage of computer-aided design software has helped machine engineers develop better working HVAC systems. You can get additional information at coolcarehvac.com

Although there are several specific developments that have helped boost the operational performance of the HVAC device, much of the overall progress may be credited to five main factors: — the production of low kW / ton chillers; — the use of high-output boiler control systems; — the use of automated direct control (DDC) systems; — the use of energy-efficient motors; and — variable matching;

The efficiency and efficiencies of chillers that worked in the range of 0.8 to 0.9 kW / ton when new have pleased building owners for years. When they mature, the real operational efficiencies at maximum load decrease to more than 1.0 kW / ton.

New chillers with maximum load-rated efficiencies of 0.50 kW / ton are being built today, an improvement of nearly 50 per cent. The part-charge efficiencies of the current generation of chillers are equally impressive. While the operational output of almost all older chillers is falling steadily with reduced load, the operational output of modern chillers is not dropping off nearly as quickly.
