What are the market prospects and energy saving methods of chillers? Chillers are mainly used in electronic industry, chemical industry, building materials industry, biopharmaceutical industry, food industry and other industries. They are not easy to be unemployed and can be used in many places. For example, if there is no chiller for chemical reaction kettle, the temperature can not be controlled, which leads to the heat released by the reaction can not be taken away and the product quality can not be achieved. The application and working principle of water chiller are not affected by the season, but are related to the cold and heat degree of the industry. Basically, it has no effect.
Energy saving method of chiller:
Prevent and reduce pipe scaling to improve the heat exchange efficiency of condenser and evaporator. If the water treatment is not good, calcium bicarbonate and magnesium bicarbonate generated by heating will deposit on the pipe.It makes the heat conduction performance decline, affects the heat exchange efficiency of the condenser and evaporator, and makes the operating electricity cost of the equipment increase greatly. At this time, in addition to the use of water treatment technology, the pipeline can also be cleaned by regular automatic cleaning equipment.
The pressure of the refrigerant which regulates the low pressure of the compressor speed increases after passing through the compressor by using the refrigerator device. The higher the compressor speed is, the higher the pressure is. In the actual operation, most of the equipment is in non full load operation, automatic adjustment of compressor speed, energy saving space is relatively large.
To reduce the condensation temperature, the evaporation temperature should be increased and the condensation temperature should be decreased as much as possible on the premise of meeting the equipment safety and production requirements. Therefore, the transformation of cooling tower is increased to ensure the cooling water efficiency.
Under the condition of ensuring the safe operation of the equipment, the power consumption per unit cooling capacity is smaller when the chiller runs at 70% - 80% load than at 100% load. The operation of water pump and cooling tower should be considered in this way.
Maintenance of chiller:
Change the lubricating oil:After long-term use of the refrigeration unit, the oil quality of the lubricating oil becomes worse, and the impurities and moisture in the oil increase, so it is necessary to observe and check the oil quality regularly. Once the problem is found, it should be replaced in time, and the brand of the replaced lubricating oil must conform to the technical data
Change the drying filter:
The drying filter is an important part to ensure the normal circulation of refrigerant. Since water and refrigerant are not mutually soluble, if there is water in the system, the operation efficiency of the unit will be greatly affected. Therefore, it is very important to keep the system dry, and the filter element inside the drying filter must be replaced regularly
Verification of safety valve:
The condenser and evaporator on the chiller are pressure vessels. According to the regulations, the safety valve should be installed on the high-pressure end of the chiller, that is, the condenser body. Once the chiller is in an abnormal working environment, the safety valve can automatically relieve the pressure, so as to prevent the possible harm to human body caused by high pressure. Therefore, the periodic calibration of safety valve is very important for the safety of the whole unit.
Refrigerant charging:
If there is no other special reason, the general unit will not produce a lot of leakage. If a certain amount of refrigerant leaks due to improper use or after maintenance, it is necessary to add refrigerant again. Pay attention to the brand of refrigerant used in the unit when charging refrigerant.
Cleaning of condenser and evaporator:
Since the cooling water of water-cooled condenser is an open circulating circuit, the tap water is generally recycled through the cooling tower. When the content of calcium salt and magnesium salt in water is large, it is easy to decompose and deposit on the cooling water pipe to form scale, which affects the heat transfer.
If the scale is too thick, the flow section of cooling water will be reduced, the amount of water will be reduced, and the condensation pressure will rise. Therefore, when the quality of the cooling water used is poor, the cooling water pipe should be cleaned at least once a year to remove the scale and other dirt in the pipe. There are usually two ways to clean the condenser water pipe: using a special pigging gun to clean the pipe. Use special cleaning agent to wash circularly, or fill it in cooling water, and change the solution after 24h until it is washed.
