6 recovery PR º ctive Recovery ctive recovery is a system of extraction air heat recovery to comply with the requirements of the regulations for energy efficiency in buildings and heating facilities, incorporating an additional cooling circuit. his additional circuit allows an increase in the nominal capacity, which increases its compactness. Furthermore as this additional circuit exchanges heat between the fresh air and extraction air in favourable conditions of temperature and humidity, a high cooling performance is obtained. herefore, the nominal performance of the unit and seasonal performances under partial load are increased. ctive recovery is available in standard version, enhanced version (with higher power recovery compressor) and version with Digital croll compressor. up to 431 kw Main and recovery circuit indoor coil Recovery circuit outdoor coil Recovery circuit compressor Dynamic Recovery he dynamic recovery is a system of energy recovery from extraction air to comply with regulations for energy efficiency in buildings and heating facilities, through an additional exchange coil (subcooler), placed in serie with the air condenser unit, which reduces the condensing pressure of the unit to operate with an average air temperature the most advantageous, and therefore achieve a significant improvement of unit efficiency by reducing the power consumption of compressors. Furthermore, this system is advantageous over static recovery systems, because it avoids higher power input of supply and return fans, by the high pressure drop of the plates or rotary heat exchangers. ubcooler industrial conditioning roof-top & wall-top roof-top air to air his system allows installation in roof-top with return fans or extraction fan, and so it is a very convenient energy recovery system for both commercial and industrial applications. 15
