Refrigeration oil is used in refrigerators that are manufactured all over the world, especially in regions such as the US, UK, Singapore, and Italy. Refrigeration oil plays an important role in refrigeration technology. The longevity expected from refrigeration units using high-quality lubricants and fluids is directly related to the quality that is desired of refrigeration oil. Unfortunately, there are many low-cost, low-quality synthetic lubricants available, which can actually do more harm than good to refrigeration equipment. This article discusses the different types of fluids and lubricants used in refrigeration applications, their suitability for different job sites, and their recommended use.
Refrigeration oils have three major functions. They include cold air control; hot air control; and mechanical control of the unit's cooling airflow. Hot air control lubricants are intended to reduce or eliminate leakage at the end of the cool forecast period. Cold air control lubricants are used to maintain the cool temperature at all times during the forecast period.
Refrigeration oil is generally classified into three types based on viscosity. Low-viscosity fluids include mineral oils, low-foaming oils, and organic oils; medium viscosity oils include vegetable oil, peanut oil, and synthetic lubricants; and high-viscosity oils include natural gas, kerosene, and diesel. The viscosity of a lubricant increases as its density decreases - such that the higher the viscosity of a fluid, the lower the density of the lubricant. In regions such as the US, the increased usage of appliances such as refrigerators has increased the usage of refrigeration oil. For instance, according to American Electronics Association, there are more than 11.41 million refrigerators in the US.
Refrigeration oil supplies manufacturers are currently seeking to improve their processes for producing refrigerants and lubricants to help them meet customer demand and supply needs. The current underutilization of the refrigeration oil market provides an opportunity for Canadian suppliers to tap into new markets for their products and services. The addition of foreign-made lubricants to the Canadian marketplace could significantly impact the demand, availability, and cost for this vital industrial commodity.
