what is an accumulator for refrigeration?

Answer 1

IT IS NOT THE DRYER as mentioned in a previous answer

It is a reservoir for refrigerant.

In large refrigeration plants, like an industrial freezer or ice cream factory, there are many different machines running on one refrigeration system.

These machines can be turned on or off individually so the load on the refrigeration system changes dramatically. As a valve opens on one machine the volume of the system increases, so more refrigerant is required. This comes from the accumulator, which is a reservior.

When a machine is turned off, valves shut and the extra refrigerant goes back to the accumulator.

Large air conditioner (which are a single machine) and low production run equipement also use accumulators to allow for the difference between summer and winter.

Mass produced refrigerators do not have accumulators. Engineers work out exactly how many millilitres of refrigerant are required, how many milli metres of copper tubing are needed. They are designed as an exact unit. If you are making 1 million refridgerators and an accumulator costs $10, they just saved $10 000 000. If one gram of refrigerant costs $1 and 1 inch of copper tubing costs $1, they just saved another $20 000 000. This is why household refrigerators do not have them.

Answer 2

Refrigerant Accumulator

Answer 3

The accumulator is a canister used to balance loads by storing excess refrigeration, it also separates liquid refrigerant from vapor. Accumulators are not used in all refrigeration units, only those that are used in areas with a wide range of conditions that put the system under large variations of load.

The item talked about above is different, its called a filter/dryer which essentially filters out debris from the system as well as absorbs excess moisture.

Answer 4

The accumulator stores the excess refrigerant as the condenser or evaporator load varies, and during the compressor off-cycle. I think this correct.

Answer 5

Also known as the dryer. It is a rubber/charcoal canister where refrigerant slows way down, like a storage tank in the bottom of a water fountain.

Answer 6

we use filter driers here in south alabama. we also use R-22 and most older systems requiring an acumalator used differernt cooling liquids . most if not all of the home systems Ive seen down here have liquid line filter drier on the high side primarily used to keep moister out of the sealed system

Answer 7

It's where you put a bet on the refridgerator finishing first in the 2.30 at Newmarket and the microwave coming second in the 4.40 at Aintree.
