Refrigeration equipment is a combination of refrigerator and facilities that use cold energy. The design and construction of refrigeration equipment is to effectively use cold energy to refrigerate food or other items; Conduct product performance test and scientific research test at low temperature; Some cooling processes are realized in industrial production or air conditioning. Articles will release a certain amount of heat when they are cooled or frozen, and the enclosure structure of refrigeration device will also introduce a certain amount of heat when it is used. Therefore, in order to maintain the low temperature condition in the refrigeration device, it is necessary to install a refrigerator to continuously remove this heat, or to absorb this heat through sublimation of melted ice or dry ice.
What are the refrigeration equipments-condensers?
It condenses the high-pressure and high-temperature refrigerant vapor sent by the compressor into liquid. There are three commonly used condensers: ① Water-cooled. With water as coolant, there are tube condenser, sleeve condenser and spiral plate condenser. ② Spray type. At the same time, water and air are used as coolants, including spray condenser (air is natural convection) and evaporative condenser (air is forced convection). ③ air cooling type. Air is used as a coolant, that is, an air condenser.
What refrigeration equipment are there-evaporators?
Evaporator, also known as heat absorber, is a heat transfer device that evaporates liquid refrigerant by boiling to cool the refrigerant or the cooled object. Evaporators are divided into two types: one is coolant type, which is used to cool liquid coolant, and there are shell-and-tube evaporators and various submerged evaporators (such as vertical tubes, spiral tubes and snake tubes). Immersed evaporator is to immerse the whole heat exchange surface in a tank filled with cooling liquid and stir it in the tank to strengthen heat exchange. The other is the cooling air type, which is used to cool the air as a coolant, and is divided into two types: tube row type and air cooler type. The tube bundle consists of vertical tubes, horizontal tubes or coils. The refrigerant boils in the tube, and the air outside the tube naturally convects. The air cooler is composed of tube bundle and fan, which makes the air outside the tube produce forced convection.
What refrigeration equipment are there-refrigerators?
Refrigerator is a machine that transfers the heat of the low-temperature cooled object to the environmental medium to obtain refrigeration capacity. The heat transmitted from a lower temperature object is customarily called cooling capacity. The working medium that participates in the change of thermodynamic process (energy conversion and heat transfer) in refrigerator is called refrigerant. The temperature range of refrigeration is usually above 120K, and 120K belongs to cryogenic technology. Refrigerators are widely used in industrial and agricultural production and daily life.
Refrigeration equipment includes evaporator, refrigerator, condenser, etc. Although all these devices have refrigeration function, their refrigeration methods and effects are different. If you need to buy refrigeration equipment, I suggest you first know what the advantages of refrigeration equipment are so as to choose the most suitable one.
