A terminal reheat all-air system is a several zone, which considers an adaptation of single zone system, as shown in Determine six. This may be carried out by introducing heating equipment, including incredibly hot h2o coil or electric powered coil, into the downstream of the availability air from air managing models in the vicinity of Each individual zone. Each individual zone is managed by a thermostat to regulate the heat output of heating devices to meet the thermal affliction. The provision air from air handling units is cooled to the bottom cooling position, along with the terminal reheat adds the required heating load.
Persons are typically baffled around the distinction between HVAC and air-con, on the other hand there is not any authentic “big difference” therefore, simply just bear in mind air con is one of several various systems that may be called an HVAC system.

Some Areas demand diverse airflow of provide air due to the alterations in thermal masses. As a result, a variable-air-volume (VAV) all-air system may be the ideal solution for achieving thermal comfort. The more info previous 4 types of all-air systems are regular volume systems. The VAV system consists of a central air managing unit which gives supply air for the VAV terminal Command box that situated in Every zone to regulate the provision air volume, as shown in Determine 8.
