Coolant<\/strong> \u2014 is a liquid or gas used in heating systems to transfer thermal energy from a heat source to end users such as radiators<\/a>, heated floors or other heating devices. The choice of a suitable heat carrier depends on the type of system, operating conditions and the required temperature regime.<\/p>\n

Coolant: main types<\/h3>\n
    \n
  1. Water<\/strong>:\n
      \n
    • Description<\/strong>: The most common and economical heat carrier, used in most heating systems.<\/li>\n
    • Advantages<\/strong>: High heat capacity, low cost, environmentally friendly, compatible with most heating system materials.<\/li>\n
    • Flaws<\/strong>: Tendency to freeze at low temperatures, possibility of corrosion of metal components of the system in the absence of anti-corrosion additives.<\/li>\n<\/ul>\n<\/li>\n
    • Antifreeze<\/strong>:\n
        \n
      • Types<\/strong>: Based on ethylene glycol and propylene glycol.<\/li>\n
      • Ethylene glycol<\/strong>:\n
          \n
        • Description<\/strong>: Highly efficient heat transfer fluid with low freezing point.<\/li>\n
        • Advantages<\/strong>: Suitable for use in conditions where there is a risk of freezing of water in the system.<\/li>\n
        • Flaws<\/strong>: Toxic, requires careful handling, especially in residential areas.<\/li>\n<\/ul>\n<\/li>\n
        • Propylene glycol<\/strong>:\n
            \n
          • Description<\/strong>: Less toxic than ethylene glycol and can be used in residential heating systems.<\/li>\n
          • Advantages<\/strong>: Suitable for use in domestic systems, has anti-corrosion properties.<\/li>\n
          • Flaws<\/strong>: More expensive and less effective than ethylene glycol.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n
          • Oils<\/strong>:\n
              \n
            • Description<\/strong>: Used in specialized heating systems where operation at very high temperatures is required.<\/li>\n
            • Advantages<\/strong>: High resistance to overheating, ability to work at temperatures exceeding 100\u00b0C without generating steam.<\/li>\n
            • Flaws<\/strong>: High cost, complexity of operation and maintenance, need for special materials for the system.<\/li>\n<\/ul>\n<\/li>\n
            • Air<\/strong>:\n
                \n
              • Description<\/strong>: Used in air heating systems where heat is transferred by means of heated air.<\/li>\n
              • Advantages<\/strong>: Does not require replacement or maintenance like liquid heat carriers, no risk of leaks.<\/li>\n
              • Flaws<\/strong>: Low heat capacity compared to liquids, high system inertia, difficulty in uniform heat distribution.<\/li>\n<\/ul>\n<\/li>\n
              • Pair<\/strong>:\n
                  \n
                • Description<\/strong>: Used in steam heating systems where heat is transferred by condensation of steam.<\/li>\n
                • Advantages<\/strong>: High heat transfer, quickly reach the required temperature.<\/li>\n
                • Flaws<\/strong>: Difficulty in temperature regulation, high risk of burns, need for high-quality pipe insulation.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n

                  Application and selection:<\/h3>\n
                    \n
                  • Residential buildings<\/strong>: Water or water-based propylene glycol antifreeze are the most common options because they are safe and effective for household use.<\/li>\n
                  • Industrial facilities<\/strong>: The use of oils or steam is justified in high temperature conditions or specific heat transfer requirements.<\/li>\n
                  • Regions with cold climates<\/strong>: Use of antifreeze to prevent freezing and damage to the system.<\/li>\n<\/ul>\n

                    The choice of coolant must take into account the operational characteristics of the system, economic feasibility and safety requirements.<\/p>","protected":false},"excerpt":{"rendered":"
