Bunn ultra-2 suction accumulator refrigeration slush


This is a brand new all-copper Refrigerant Suction Accumulator for the Bunn Ultra-2 machine, Bunn part number 32257.0000. This part may be replaced during a repair or overhaul of the refrigeration system in your machine and therefore requires professional installation by an EPA-certified refrigeration technician.
The purpose of an evaporator is to absorb heat. The way that this is accomplished in your Bunn machine is through one of the fundamental laws of physics dealing with the amount of heat absorbed when a substance changes state from liquid to vapor. This is exactly what happens in the evaporator when the refrigerant changes state from a liquid to a vapor - the reaction requires heat, thus causing relative cooling.
The amount of heat that your evaporator can absorb varies, depending on many changing circumstances. Therefore sometimes there is some leftover refrigerant in liquid form. The consequences of this liquid spilling down the suction line are undesirable. Namely, frost on the outside of the suction line, and harm to the compressor. The accumulator is a device that is made to collect and use up leftover refrigerant in a liquid state.
