Title of the articleThe expediency of the air conditioning system with cold accumulation
Abstract.Consumption of cold air-conditioning systems is unequally throughout the day. This makes it possible to accumulate cold during small consumption and to use it during the maximum consumption. This measure significantly reduces installed power of the chiller and its power of communication, which leads to a significant reduction in investment. It needs a simple (collecting sensible heat) or active (using the heat of phase transformations) storage tank for cold accumulation, which requires additional investment. Accumulation of cold can be done at night, with a more economical power rate, thus reducing operating costs. This article focuses on the technical and economic evaluation of the cold accumulation for air-conditioning systems. Within of these models (simple and active storage tanks, operating and cost parameters) it is found that, usage of accumulation can lead to a significant reduction in money resources taking into account the cost of connection to the grid power. The greatest economic effect is achieved when the share of the cold accumulation is about 0,4 of the daily cold’s requirement. The decrease of resulted expenses, taking into account the reduction of investment and annual operating costs are up to 40?45 %.
Keywords.accumulation of cold, consumption, night tariff, chiller, cost.
