Suction Accumulators
& Sub-Coolers
 

Suction Accumulators

In large holdover plate refrigerator and freezer systems, liquid refrigerant can condense in the plate evaporator lines when the compressor is not running.  On startup, this liquid is suddenly dumped into the compressor causing liquid "slugging" which can cause damage.  Installing a suction accumulator in the suction line protects the compressor from this liquid slugging by ensuring that only gas is returned compressor.

NOTE:  Suction accumulators must be installed with the "inlet" and "outlet" properly connected. All RParts suction accumulators are marked to ensure proper installation. Reversing the flow through any of these suction accumulators will result in oil being trapped and severe compressor damage.

Combination Accumulator/Sub-Cooler
 
This unique product combines a sub-cooler (see below) and suction accumulator into a single compact unit. This sub-cooling is done using a separate heat exchange coil within the suction accumulator.  During installation, both the suction line and liquid line (as it exists the condenser) are routed through this unit.  The cold gas from the suction line cools down the warmer liquid giving an overall improvement in system efficiency.

 Sub-Coolers
The term "sub-cooling" refers to the process of further cooling the liquid refrigerant (after it exits the condenser) to a temperature below its "dew point (i.e  the temperature at which the gas condenses into a liquid).  Passive sub-coolers (the type sold by RParts) accomplish this by using the cold gas returning from the evaporator to remove heat from the condensed liquid.  The result is a substantial improvement in energy efficiency and system capacity.

Like all heat exchangers, the construction quality of a Sub-Cooler significantly impacts its effectiveness.  RParts sells on the top-of-line, 100% enclosed units for maximum performance. 

Select based on the HP of the compressor.
