Overview of industrial cooling machine

Equipment used in refrigeration operations. Different refrigeration methods use different equipment. Currently, the most widely used one is vapor compression refrigeration. The main equipment includes compressors (fluid conveying machinery), condensers, evaporators and throttle valves.

Working principle of industrial cooling machine

The refrigeration principle of general refrigeration equipment is that the function of the compressor is to compress steam with lower pressure into steam with higher pressure, so that the volume of the steam is reduced and the pressure is increased. The compressor inhales the lower-pressure working fluid vapor from the evaporator, raises the pressure, and sends it to the condenser. It is condensed into a higher-pressure liquid in the condenser. After being throttled by the throttle valve, it becomes a higher-pressure liquid. After the low-pressure liquid is sent to the evaporator, it absorbs heat and evaporates in the evaporator to become steam with a lower pressure, and then is sent to the inlet of the compressor to complete the refrigeration cycle.

Application of industrial cooling machine

Refrigeration devices are designed and built to effectively use cold energy to refrigerate food or other items; to conduct product performance tests and scientific research tests at low temperatures; to implement certain cooling processes in industrial production, or to perform air conditioning. When items are cooled or frozen, a certain amount of heat is emitted, and a certain amount of heat is also introduced into the enclosure of the refrigeration device when in use. Therefore, in order to maintain low temperature conditions in the refrigeration device, a refrigerator must be installed to continuously remove the heat, or absorb the heat by melting ice or sublimating dry ice.

Classification of industrial cooling machines

1. The cooling methods of refrigeration equipment are divided into two types: direct cooling and indirect cooling.

① Direct cooling is to install the evaporator of the refrigerator in the box or building of the refrigeration device, use the evaporation of the refrigerant to directly cool the air in it, and rely on the cold air to cool the objects that need to be cooled. The advantages of this cooling method are fast cooling speed, small heat transfer temperature difference, and relatively simple system, so it is widely used.

②Indirect cooling relies on the evaporation of the refrigerant in the evaporator of the refrigerator to cool the secondary refrigerant (such as salt water), and then the secondary refrigerant is input into the box or building of the refrigeration device, and the air in it is cooled through the heat exchanger . This cooling method has a slow cooling speed, a large total heat transfer temperature difference, and a more complex system, so it is only used in fewer situations, such as salt water ice making and cold storage with constant temperature requirements.

2. According to the working principle, it can be divided into:

①Compression refrigeration machine. Relying on the action of the compressor to increase the pressure of the refrigerant to achieve the refrigeration cycle, according to the type of refrigerant, it can be divided into vapor compression refrigeration (based on hydraulic evaporative refrigeration, the refrigerant undergoes periodic gas-liquid phase changes) and There are two types of gas compression refrigerators (based on high-pressure gas expansion refrigeration, the refrigerant is always in a gas state).

②Absorption refrigeration machine. Relying on the action of the absorber-generator group (thermochemical compressor) to complete the refrigeration cycle, it can be divided into three types: ammonia water absorption type, lithium bromide absorption type and absorption diffusion type.

③Steam injection refrigeration machine. The refrigeration cycle is completed by the action of a steam ejector (jet compressor).

④Semiconductor refrigeration machine. Use the thermo-electric effect of semiconductors to produce cold energy.
