HYZOE Refrigeration Analysis of the Advantages, Disadvantages and Effects of Using Coolants in Indus
During installation and use, HYZOE refrigeration should choose the refrigerant or refrigerant carrier according to the actual use. Refrigerants, also called refrigerants, are substances that transfer heat in an indirect cooling system. After the refrigerant is cooled in the evaporator, the refrigerant is sent to a cooling object or a cooling device to absorb the heat of the cooling object, and then returns to the industrial chiller evaporator to transfer the absorbed heat to the refrigerant. The refrigerant is cooled again so that the cycle cannot be stopped, thereby achieving the purpose of continuous cooling.
It can be seen that the refrigerant in the indirect refrigeration system connects the refrigeration system with the cooling system and plays a role in the transfer of cooling capacity. Refrigerants are usually liquids and have no phase change during heat transfer. The advantages and disadvantages of refrigerants are as follows:
HYZOE refrigeration analysis advantages of using refrigerants in industrial chillers:
1. Centralize various equipment of chiller for easy operation and management.
2. The cooling capacity can be sent away from the cooling system to facilitate the distribution and control of the cooling capacity.
3. Reduce the total volume of the refrigerant piping system, thereby reducing refrigerant charging and leakage during operation.
4. The heat capacity of the refrigerant is generally large, so the refrigerated material temperature of the industrial chiller is easy to maintain stability.
Disadvantages of using refrigerants in industrial water coolers:
1. The entire chiller system is complicated, and the refrigeration system is added on the basis of the refrigeration system.
2. The temperature difference between the primary heat transfer between the cooling substance and the refrigerant increases, and the loss of cooling capacity increases.
In order to achieve more energy-saving purposes, direct cooling systems should be used as much as possible to avoid refrigerant carrier systems. However, in some cases, a refrigerant system must also be used. The functions of the refrigerant system are as follows:
1. As a refrigerant delivery, storage and distribution system, refrigerants can be used to provide cooling for remote and dispersed users.
2. It can make the suction pipe of industrial chiller short and straight, simple in shape, low in resistance, and improved the cooling coefficient (COP).
3. Increasing the heat capacity of the refrigeration system can reduce the temperature fluctuations of the system, making it easier for industrial chillers to meet the needs of users who strictly limit temperature fluctuations.
4. Some materials coolers cannot be made into pressure vessels (or because the diameter of the vessel is too large, the pressure is too thick and the wall is too thick and uneconomical). The first test was to use an open refrigeration system to avoid putting pressure on the container. This is even more important for low-temperature industrial chiller cooling systems.
5. The use of refrigerant cooling technology has fewer problems than the direct evaporation cooling technology, because the direct evaporation circuit is a two-phase flow, and sometimes the refrigerant distribution is difficult to uniform, which not only reduces the efficiency of the evaporator, but also makes the temperature distribution uneven, and uses The refrigerant can easily meet the requirements. 2.png
6. Some industrial chiller refrigeration systems, such as high and low temperature laboratories, are subjected to excessive pressure in high temperature experiments, and the use of refrigerant carriers can solve the problem of excessive pressure.
In short, in many cases, the application of industrial chiller will be more flexible, stable and effective after adding refrigerant loading system. Therefore, the refrigerant carrier system has been widely used in practical engineering
