Seasons 4 - Commercial Heating and Cooling System Manufacturers

Energy recovery is another approach to humidity control that uses energy from one source to provide energy for other work in the same system.  Through the use of subcooling (reducing refrigerant temperature in the liquid line below saturated temperature), energy is recovered and as much as 15 to 20% additional capacity is added to the evaporator. 

The energy required for this is taken from the leaving air of the evaporator coil and, depending on the airflow the coil handles, results in a 7-10 degree temperature rise.  The result of this is that more capacity is gained in the liquid subcooling phase than is lost in the air reheating.  The energy savings can be seen in the fact that the compressor KW does not change.

The result is a remarkably efficient system.  Like all Seasons•4 systems, it offers:

• Independent return air circuit parallel to outdoor air circuit treats sensible load requirements of space, giving your system built-in flexibility
• Motorized outdoor air with cost-efficient night-bypass damper
• Manual balance dampers in outdoor and return air plenum for easy, fast fine tuning
• Heat reclaim coils use waste heat derived from your refrigeration system to offset requirements for comfort zone heating
• Auxiliary heat section is specifically designed for your location’s requirements
• Low velocity pleated, long-lasting air filters
• Backward inclined airfoil blade blowers for high-efficiency operation
• Premium efficiency 4-pole motors (exceeds EPAC requirements)
• Single point power connection for easy installation
• Spacious cabinet design with full height access doors, with single handle, multiple point latches, for easy access and maintenance
• Oversized condenser coils designed for higher efficiency and energy savings
• Factory mounted 24-volt controls are compatible to the computer hardware of your choice. Your control system matches your specifications exactly.
