Scr electric heater application guide.
Vav box with electric reheat coil. Single duct terminals are the fundamental building blocks for variable air volume vav systems. Designed for cooling only cooling with reheat heating only or heat cool changeover applications. Electric reheat coils are an available accessory for use with price single duct and fan powered terminal units. This article will focus on cooling with electric reheat vav boxes.
Lynergy scr electric heater application guide. The price electric coils are designed to be utilized in environments where. Quiet type with dissipative silencers and hospital grade boxes are also available. Nailor 3000 and 3100 series terminal units are among the most versatile vav boxes on the market providing easy hvac system integration with diverse control packages.
Zone with its vav box wide open maximum air flow to the zone. See electric heat unit selection heating coil selection if required first determine the amount of heat required to meet space and downstream duct heat losses from a load calculation. Old style electric heater iom units shipped before june 1 2001 quick reference guide high res. Tu accessories catalog section.
At the vav box selection step in the design process all air distribution zones the required rate of cooling and heating supply airflow per zone and the number of vav boxes per zone should be established. Electric heating coils. Quick reference guide low res. The heat source in many variable air volume boxes are typically electric but can also be a hot water coil.
The thermostat and the controller will also turn on the heat whenever the temperature in the space falls below the set point as determined by the thermostat and pre. Note that if an electric reheat box was selected the minimum cfm would be dependent upon the kw of the electric heater. The zones with lesser cooling demand will throttle their vav boxes down as far as their minimum flows and if the air is still too cold will then reheat the air using a hot water or electric resistance coil at each zone.
