SELECTION OF THE OPTIMAL HEATING COOLANT FOR ARM DEPENDING ON THE TECHNICAL CONDITIONS OF THE OIL AND GAS ENTERPRISE

Abstract

Generation of cold is great demand process for many enterprises of the oil and gas industry. With large capacities of the enterprise, deeper cooling of heat carriers is required in chemical and petrochemical industries, metallurgy, compressor stations, etc. In administrative buildings and workshops located on the sites, it is required to create comfortable conditions in the buildings for the people who are there. In this regard, the demand for refrigeration units is increasing. Until recently, steam compression refrigerating machines were the market leader in refrigeration units. However, their main disadvantage is the high consumption of electricity, and often the process of generating cold has become too expensive.Relatively recently, steam compression refrigerating machines (chillers) have been replaced by absorption refrigerating machines (ARM). Their main and key feature is that they generate cold without consuming a single kilowatt of electrical energy, since the process of generating cold is based on the thermophysical properties of low-boiling solutions of lithium bromide or ammonia.
