One of the traditional ways of reducing energy
consumption is the utilization of seasonal cold
accumulator which takes advantage of the
geographical location of a country that allows, during
the winter season, that is, November, December,
January, February, March accumulates cold as a result
of lower ambient temperature in these months.
Significant amount of electricity is reduced as well as
reduced operating refrigerant, which is harmful to the
environment. The article presents determination of the
size of cold storage with charging devices as chiller
and dry-cooler. The approximate costs of the device
operation as well as the time of assembly of these
components have been obtained. The design of a
seasonal cold accumulator is a system that brings a
number of economic and ecological advantages. The
seasonal tank design is a prototype of the chiller; it is
smaller than the actual tank that will be selected for the
highest hourly energy demand. This means that the
actual device should be several times larger than the
device that was used in the project. By selecting a
small chiller and fewer refrigerants (mainly
chlorofluorocarbons) called R- 410A, the environment
would be saved from contaminants which are
hazardous
There is always an abrupt variable schedule of cooling
consumption in processing enterprises with seasonal
supply of raw materials. This causes peak heat load on
the refrigeration unit. The introduction of cold
accumulators (CA) in refrigeration units is one of the
modern ways of reducing the cost of refrigeration. The
use of cold accumulators allows you to smooth out
uneven thermal load on refrigeration, reduce the
cooling capacity of the installed equipment and
technical equipment. The night season experiences
minimum heat leakage and power consumption of
frozen ice water (coolant or refrigerant) but the
refrigeration capacity is used during the daytime at
peak heat load of cold consumption at peak electricity
consumption. The major cost of electricity to generate
refrigeration to compensate for heat loss coincides
with the period of high electricity tariffs as shown
from the analysis of cold consumption. The
development of refrigeration systems with cold
accumulation in “night” period of low electricity tariffs
is an important issue based on the forgoing
