Energy saving AHUs: project and design
Energy saving AHUs: project and design How can we satisfy the requirements of the (previous) laws and ENI 13779, whenever we proceed with a new installation of a system? What can we propose?
‹N°›
Project and design
Traditional solutions for «primary» air handling • Air Handling unit with recovery (eg PHE)
+ heat coil (gas boiler)/Humidification+ cool coil (chiller)/post-heating;
• Air Handling unit with recovery (eg PHE)+ heat/cool coil+ reversible heat pump;

Heat pump: break-even pointGerman market Gas cost = 0,65 ¤/mc (april 2012) «specific energy» gas = around 10 kWh/mc Gas cost kWh = 0,065 ¤/kWh Electricity cost /kWh = 0,165 ¤/kWh Break-even point = 0,165/0,065 = 2,6 So, if the heat pump (HP) has a medium season COP over 2,6, it is convenient ENERGETICALLY to use it, instead of a traditional gas heater

Innovative solution for «primary» air handling In this field, the new ENERGYAir Handling unit by Aermecis becoming a leader technology. • Fresh air handler, «all-in-one» solution (heat pump built
in); • High efficiency unit, so whenever an energy saving
solution is needed, ENERGY is the right one; • Plug ‘n’ Play; • The concept is: energy available where it is needed
and when it is needed;

Characteristics
Plug and play: units ready to use without the intervention of the installer on the refrigerant circuit and the electrical wiring. Possible combination with the modules of the NCT: are available so all the typical components of power plants (silencers, absolute filters, etc.). The technical normative are respected, in particular EN1886: mechanical resistance of the casing, leakage of the body, by-pass filter, thermal conductivity, thermal bridges, - EN 13053: with respect to certain design features and sanitary products;
