Description

Technical Field

[0001] The utility model relates to the technical field of refrigerant stock detection, in particular to a container refrigerant stock detection device. Background Art

[0002] Refrigerant, also known as refrigerant, is the working medium of the refrigeration cycle. It uses the phase change of refrigerant to transfer heat. The refrigerant absorbs heat when it vaporizes in the evaporator and releases heat when it condenses in the condenser. There are more than 80 substances that can be used as refrigerants. The most commonly used are ammonia, Freon, water and a few hydrocarbons. The main classifications are: 1. The refrigerants widely used in compression refrigerants are ammonia, Freon and hydrocarbons. According to the chemical composition, refrigerants can be divided into five categories: inorganic compound refrigerants, Freon, saturated hydrocarbon refrigerants, unsaturated hydrocarbon refrigerants and azeotropic mixture refrigerants. According to the condensing pressure, refrigerants can be divided into three categories: high-temperature (low-pressure) refrigerants, medium-temperature (medium-pressure) refrigerants and low-temperature (high-pressure) refrigerants. 2. Inorganic compound refrigerants: This type of refrigerant was used relatively early, such as ammonia (NH3), water (H2O), air, carbon dioxide (CO2) and sulfur dioxide (SO2). For inorganic compound refrigerants, the internationally specified code is R and the following three digits, where the first digit is "7" and the last two digits are the molecular weight, such as water R718... etc. 3. Freon (halocarbon refrigerant): Freon is a saturated hydrocarbon that is completely or partially A general term for derivatives of hydrogen (CL), fluorine (F) and bromine (Br). International regulations use "R" as the code for this type of refrigerant, such as R22... etc. 4. Saturated hydrocarbons: This type of refrigerant mainly includes methane, ethane, propane, butane and cyclic organic compounds. The code is "R" like Freon. This type of refrigerant is flammable and explosive and has poor safety, such as R50, R170, R290... etc. 5. Unsaturated hydrocarbon refrigerants: This type of refrigerant mainly includes ethylene (C2H4), propylene (C3H6) and their halogen element derivatives. The number after the R in them is mostly "1", such as R113, R1150, etc. 6. Azeotropic mixture refrigerants: This type of refrigerant is an azeotropic mixture formed by mixing two or more different refrigerants in a certain proportion. This type of refrigerant can maintain a certain evaporation temperature under a certain pressure, and the gas or liquid phase always maintains the same composition ratio, but their thermodynamic properties are different from those of the substances before mixing. The use of azeotropic mixtures can improve the characteristics of the refrigerant, such as R500, R502, etc. 7. High-temperature, medium-temperature and low-temperature refrigerants are divided according to the refrigerant's standard evaporation temperature and condensing pressure at room temperature.
