FREE-COOLING IN SEASONAL COLD ACCUMULATOR
Description
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

OPTIMIZATION OF THE ENERGY CHARACTERISTICS OF A CHILLER WITH COLD ACCUMULATOR IN TROPICAL CLIMATE
Description
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
