Refrigerating system
Refrigerating system	Refrigeration methods are divided into vapor compression refrigeration, absorption refrigeration, vapor injection refrigeration, gas expansion refrigeration, thermoelectric refrigeration. Among the above refrigeration methods, vapor compression refrigeration is the most economical and most widely used refrigeration method, and is also the most commonly used refrigeration method in environmental test equipment. Its principle is to use the evaporation potential of environmental freon and other liquids to absorb heat from the cooled object and achieve refrigeration. (single stage refrigeration cycle diagram) is a schematic diagram of the steam compression refrigeration cycle process. The liquid that is throttled into the evaporator through the expansion valve absorbs the latent heat of evaporation from the surrounding objects and evaporates. After evaporation, it becomes low-temperature and low-pressure gas and is sucked into the refrigeration compressor. After being compressed by the compressor, it becomes high-temperature and high-pressure gas and enters the water-cooled or air-cooled condenser, where it is cooled into high-pressure liquid and then enters the evaporator through the expansion valve. In this cycle, heat is absorbed from the cold to cool, and heat is released from the hot. A change from one state to another in the refrigeration cycle shown is called a process. There are four processes in the refrigeration cycle. The following is a brief description of the four processes in the refrigeration cycle. (1) Evaporation process: through the expansion and throttling of low pressure wet steam, in the evaporator from the surrounding medium to absorb heat refrigeration, and gradually increase its dryness. The gas that comes out of the evaporator is either dry saturated or slightly superheated. During evaporation, the refrigerant temperature and pressure remain constant. (2). Compression process: after the completion of refrigeration, the vapor from the evaporator enters the refrigerator. After compression, the temperature and pressure rise sharply. So the gas that comes out of the refrigerator becomes a superheated hot vapor. During the compression process, the entropy of the refrigerant remains constant. (3). Condensation process: the high temperature and high pressure superheated vapor discharged from the refrigerator is exchanged with cooling water or air after entering the condenser, so that the superheated vapor gradually becomes saturated vapor, and then becomes saturated liquid. Saturated liquid temperature when cooled with cooling water The degree will continue to drop and there will be supercooling. The pressure remains constant during condensation. (4) throttling process: the liquid from the condenser is throttled through the expansion valve or capillary throttling device to become low temperature and low pressure wet steam, and the enthalpy value of the refrigerant remains unchanged during the throttling process. The above four cyclic processes are continuously circulated in turn to achieve the purpose of refrigeration. In order to complete the thermodynamic process of the refrigeration cycle, the compressor, heat exchanger, pipeline, pipeline accessories, etc., need to be composed of a system, the system is called refrigeration system. Single-stage compression refrigeration means that the refrigerant vapor is compressed only once, and its lowest evaporation temperature can be controlled between -30ºC and -40ºC. When a lower test temperature is needed, the overlapping refrigeration system is usually used, that is, two single-stage compression refrigeration systems are overlapping. One system is the high temperature part, using medium temperature refrigerant; the other system is the low temperature part, using low temperature refrigerant. The high-temperature evaporator and the low-temperature condenser are overlapped to form the condensing evaporator.
Refrigeration compressor	Originally imported from France "Taikang" fully enclosed compressor or "Emerson" fully enclosed compressor
Condenser	The high temperature and high pressure vapor discharged from the compressor is cooled into a liquid; The heat released is carried away by water or air. Can be divided into water - cooled, air - cooled
Evaporator	Vaporize a liquid into a gas; Absorb heat or dehumidify
Device for drying and filtering	Absorb the residual water and acid in the refrigerant of the refrigeration system, filter out the solid impurity particles in the system, copper cutting, etc., protect the normal operation of the expansion valve and capillary, and avoid the occurrence of ice blockage and water blockage
Oil separator	The Emerson oil separator separates the refrigerant from the liquid that is ejected from the compressor to protect the compressor from the loss caused by the accumulation of refrigerant liquid (usually used in overlapping systems or large single systems).
Refrigeration system technology	The low-temperature connecting pipes are made of high-quality oxygen-free copper pipes, and the famous "Rosenberg" electric pipe bender is used for pipeline fabrication, nitrogen filling welding, and 48-hour high pressure and leakage prevention process to ensure the welding quality Pipeline welding: The high quality copper pipe nitrogen protection welding mode, so that the copper pipe inside smooth no oxidation, avoid the traditional welding mode caused by oxide impurities in the inner wall of the copper pipe into the refrigeration system to the compressor damage. Vibration reduction measures: the compressor is installed at the bottom of the vibration reduction spring and anti-vibration soft rubber pad combination vibration reduction; Anti-vibration hoses and C-shaped elbows are added to the pipes of the refrigeration system to avoid cracking of copper pipes caused by vibration and temperature changes, resulting in refrigerant leakage and affecting the overall performance of the system. Noise control: Low speed and high air volume condensing fan is used on the condenser to achieve low noise effect
