Refrigerants

Introduction

Refrigerants are important working substances in refrigeration equipments, which determines the working temperature and efficiency of refrigeration equipment. They can continuously circulate in the refrigeration system and achieve refrigeration through their own state changes. The selection of refrigerants should consider their low-temperature heat transfer performance, chemical stability and safety. Among them, organic fluorides have the characteristics of good thermal stability, chemical inertness, large heat of evaporation and non-flammability, and can be used to evaporate and condense at lower temperatures, so they are widely used in refrigerants.

Advantages Of Organic Fluorides In Refrigerants

Compared with conventional refrigerants, organic fluorides as refrigerants have the following advantages.

• Efficient. Organic fluorides have large heat of evaporation, and more efficient exchange of heat and cold in the evaporator and condenser, which can reduce the temperature to the required range in a short time. At the same time, the thermal conductivity of organic fluorides is also very stable and will not fluctuate greatly due to temperature changes. These make the use of organic fluorides in refrigerants more efficient in refrigeration.
• Highly adaptable. Organic fluorides have high chemical stability and will not undergo chemical reactions due to factors such as temperature and pressure. Therefore, the use of organic fluorides in refrigerants have very stable refrigeration performance and have a wide range of adaptability. They can be used for refrigeration in different environments and can be adapted to different refrigeration equipment.
• Safety. Organic fluorides are non-flammable and non-explosive, and they are safer and more reliable to use, making them widely used in refrigerants.

Applications Of Organic Fluorides In Refrigerants

The organic fluorides used in refrigerants mainly include four types, namely chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs) and hydrofluorooolefins (HFOs). CFCs have been discontinued because they are highly destructive to the ozone layer and significantly contribute to global warming. HCFCs are important refrigerants that replace CFCs and they are widely used in refrigeration equipments. The ozone depletion potential (ODP) of HFCs is zero, and have no destructive effect on the ozone layer. Due to their characteristics of excellent energy efficiency and environmental protection, they have been rapidly and widely used in the refrigerants industry since their launch. The ODP of HFOs is also zero, with ultra-low global warming potential, and they have minimal impact on climate warming. They are the new generation of refrigerants that are much more environmentally friendly than HCFCs and HFCs, and have a huge market potential in refrigerants.

Refrigeration Principle Of Refrigerants

When organic fluorides are used as refrigerants, their refrigeration principle is mainly based on the state-changing characteristics of organic fluorides, and the refrigeration effect is achieved through continuous exchange of cold and heat in the evaporator and condenser. Specifically, the organic fluorides in the evaporator evaporate into a gaseous state under low pressure, absorbing the surrounding heat and lowering the surrounding temperature. The high-temperature and high-pressure organic fluorides are cooled down by the condenser and become liquid, releasing the absorbed heat. The liquefied organic fluorides enter the evaporator again for the next round of refrigeration process. By continuously cycling this process, the effect of lowering the ambient temperature is achieved.
