What are the refrigeration equipment - condenser, the compressor sends out the high-pressure, high-temperature refrigerant vapor condensation into liquid. Commonly used condenser has three categories:
1 water-cooled. With water as the coolant, there are tube condenser, casing condenser and spiral plate condenser.
2 Spray type. At the same time to water and air as a coolant, there are spray condenser (air for natural convection) and evaporative condenser (air for forced convection).
3 Air-cooled. Air as a coolant, that is, air condenser.
What are the refrigeration equipment - evaporator, evaporator, also known as heat absorber, is through the boiling vaporization of liquid refrigerant to make the refrigerant or cooled objects cool down the heat transfer equipment. Evaporator can be divided into two categories: one is the cooling liquid type, used to cool the liquid refrigerant, shell and tube evaporator and a variety of submerged evaporator (such as riser, spiral tube, snake tube type). Immersed evaporator is the whole heat transfer surface immersed in the tank containing refrigerant, the tank is stirred to strengthen the heat transfer. Another type is the cooling air type, used to cool the air as the refrigerant carrier, and is divided into two kinds of tube row and chiller. Tube row consists of vertical tube, horizontal tube or coil, refrigerant boiling in the tube, the tube outside the air for natural convection, the chiller is composed of tube group and fan, so that the tube outside the air for forced convection.
What are the refrigeration equipment - refrigeration machine, refrigeration machine (refrigeration machine) will have a lower temperature of the object to be cooled by the transfer of heat to the environmental media so as to obtain the cold machine. The heat transferred from the lower temperature object is customarily referred to as cold. Refrigeration machine involved in the thermal process changes (energy conversion and heat transfer) of the material is called refrigerant. The temperature range of refrigeration is usually above 120K, and below 120K is the range of deep cryogenic technology. Refrigerators are widely used in industrial and agricultural production and daily life.
