Facade Fan Coil Unit Type A/C System FVM for Decentralized Ventilation with Outside Air via the Facade and for Heating and Cooling Application Decentralized modular A/C system, flush mounted in a single- shell facade, for decentralized ventilation of occupied rooms via the facade using outside air, as well as for heating and cooling. All functions integrated in one ready- to- install unit. - - Functions - Ventilation (air diffusion + return) - Outside air filtering F7 - Heating and cooling in the outside air and recirculating air mode - Heat and humidity recovery WFRG (heat and humidity recuperation)...

Facade Fan Coil Unit Type A/C System FVM Advantages Minimum space requirement even when installed in single- shell facades: width: 450 mm, depth: 160 mm, height: 2680 mm. Maximum space efficiency due to savings in floor height, shaft surfaces, and technician rooms. Modular construction, extendable in steps from static heating to air conditioning, therefore - no unnecessary preparation costs - easy retrofitting - unlimited tenant/user flexibility High user acceptance due to individual operability. Complete, discrete integration in the facade - due to low unit depth and with - due to flush facade...

Facade Fan Coil Unit Type A/C System FVM Due to the many parameters decisive for a decentralized unit’s output we will state one example only. Further dimensioning on request using a specific program. Example for: Type Outside air flow rate Room temperature Water intake temperature Nominal water volume Speed outside air and exhaust air fan Speed secondary air fan Heat and humidity recovery Overall cooling capacity with different water flow rates 550 525 Flow rate in % of the nominal flow rate Wasserseitiger Druckverlust pw [kPa] Cooling capacity Qk [W] Room-effective cooling capacity with different...

Facade Fan Coil Unit Type A/C System FVM Control Frost Protection When integrating the A/C system type FVM into a closed- loop control circuit the following particuliarities will have to be considered: In the decentralized A/C system type FVM, both outside air and room air are routed through the heat exchanger. As outside air temperature variations can be significantly higher than intake temperatures in standard recirculating air units, standard fan coil unit control strategies cannot be used without making certain modifications. Since the heat exchanger in decentralized A/C units can handle...
