Description

Nominal RW-SLHE selections should be based on system horsepower, which will provide a nominal 10ºF subcooling and a nominal 20ºF suction superheat for R-22, R-502, R-404A, R-507, R-407A, R-504, R-134A, R-407C and R-410A at 110ºF condensing and 25ºF suction. For example, for a 1-1/2 HP system, select an RW-SLHE 1-1/2. Do not select undersized models to avoid high suction pressure drops and gas whistling.

Selections based on suction and liquid line sizes are appropriate for standard low, medium and high temperature refrigeration systems provided the system HP rating closely matches the RW-SLHE selection.

Selection of oversized models will provide additional liquid subcooling and suction superheat. Oversized models are acceptable only if the suction gas temperature to the compressor is not raised above 65ºF for proper compressor performance.

Standard and custom models can be selected by Doucette to meet any performance criteria, up to 60ºF subcooling. For exacting subcooling and superheat performance please contact the factory.

Applications

(For enhanced evaporator capacity, system stability, compressor protection and oil return.)

Functions
  • Increased Performance and System Protection for Minimal Cost
Suction Line Heat Exchangers (SLHE) improve refrigeration system performance and are a proven refrigeration system component for greater efficiency. These heat exchangers protect the compressor and are highly recommended by equipment manufacturers for medium and low temperature, space sensitive applications.
By subcooling the hot refrigerant liquid, evaporator coil capacity is increased and overall refrigeration system reliability improved. As a rule, 1ºF refrigerant subcooling results in 0.5% capacity improvement. A nominal SLHE selection will provide 4% to 10% coil capacity improvement along with improved system pull-down time.
  • Protects Compressor From Premature Failure
Refrigerant droplets can cause serious compressor damage. Doucette Suction Line Heat Exchangers protect the compressor by "vaporizing" droplets as they pass through the heat exchanger, greatly reducing the chance for premature compressor failure.
  • Improves Expansion Valve Operation
Flucation in operating conditions such as low-ambient and low-load can cause a refrigeration system to experience expansion valve "hunting" and liquid line bubbles. Doucette's Suction Line Heat Exchangers help eliminate this problem and provide improved expansion valve operation and proper capillary performance.
  • Reduces Suction Line Sweating and Improves Oil Return
Doucette Suction Line Heat Exchangers reduce line sweating and frost formation by raising the temperature in the suction piping. This diminishes water and corrosion damage to other equipment. Oil return is improved from the increase in suction gas temperature.
