WebThis double-reheat has an electrical efficiency one to two percentage points greater than a single-reheat system. Most double-reheat units were built in the 1960s and 1970s in Germany, the USA and Japan. They fell out of favour in the 1970s as other fuels became more widely used. By 1998, 37 coal-fired double-reheat units, amounting to 17.7 GWe ... WebA VAV — i.e., Variable Air Volume — HVAC (heating, ventilation, and air conditioning) system that supplies air at varying levels or amounts at a constant temperature. In contrast to constant airflow systems, which supply air at variable temperatures, VAV HVACs are preferred for their greater temperature control, longer parts life, reduced ...
