36. Seasons-4 Energy Recovery Systems
Energy recovery can substantially reduce mechanical heating and cooling requirements associated with conditioning ventilation air in most buildings, specially buildings require 100% outside air at high ventilation rates.
Seasons-4 offers the most commonly used energy recovery systems.
1- Energy Recovery Wheels
a) Enthalpy Wheels
b) Sensible Wheels
c) Desiccant Wheels
3- Heat Pipes
4- Run-Around Loops
2- Air to Air fixed flat Heat Exchangers 1

37. Energy Recovery Wheels:
Energy recovery wheels are the most efficient energy recovery devices, effectiveness ranging from 50% to 80%. The wheels require routine maintenance of the belt and the motor and good filtration.

39. Energy Recovery units with an Enthalpy wheel and a Sensible wheel in each unit.

40. FIXED-FLAT HEAT EXCHANGERS
Plate heat exchanger are the second most efficient energy recovery systems, effectiveness ranging from 50% to 75%. Their most distinct advantage is that they have no moving parts.

45. Heat Pipe Heat Exchangers:
Heat pipe heat exchangers have the appearance of ordinary finned coils with specific amount of refrigerant . Effectiveness between 50% to 65%.
Because they lack moving parts, Heat Pipes are low maintenance and very rarely fail.
