enVerid Systems, developers of the HLR® solution to reduce HVAC energy consumption, announced the availability of its next generation, “all season” system that the company says reduces both cooling and heating energy consumption by 20-40 percent.
An undercharge of refrigerant will cause low head and suction pressures, but that is not the only thing that will cause both pressures to be low. An undercharge will have low condenser liquid subcooling readings on the high side, where a dirty air filter for the evaporator will not produce low condenser liquid subcooling readings.
This LED light kit is an option for the high-velocity, low-speed (HVLS) fan line AirVolution-D. It is suited for those looking to eliminate the effects of strobing caused by nearby ceiling lights shining through the fan’s blades.
