What is the impact of excessively high exhaust temperature of a 50 ton chiller?
If the exhaust temperature of the compressor is found to be too high during the use of the LC -25°C ~ -5°C Low Temperature Chillers, it should be stopped immediately for a comprehensive inspection.
Otherwise, it will cause overheating of the dedicated refrigeration compressor for the 50 ton water chiller, leading to overload of the compressor, which can seriously lead to cracking of the compressor cylinder, causing a significant safety accident.
During the operation of a 50 ton water chiller, excessive compressor exhaust temperature of the 50 ton water chiller will directly reduce the gas transmission coefficient of the refrigeration system and increase shaft power.
Moreover, it can cause the viscosity of the lubricating oil in the refrigerant to decrease, which can cause abnormal wear of the compressor bearings, cylinders, and piston rings, and even cause accidents such as burning out the bearing shells and cylinder galling.
During the operation of a 50 ton water chiller, the operator should promptly check the overheating condition of the refrigeration compressor of the 50 ton water chiller.
If the compressor exhaust gas is excessively overheated, it can lead to excessive expansion of the compressor piston and seizure in the compressor cylinder, and also cause the burning of the built-in motor of the closed compressor.
In addition, if the compressor exhaust temperature in a 50 ton water chiller is too high, it will directly lead to the thermal decomposition of the compressor lubricating oil and refrigerant under the catalysis of high-temperature metal materials, and generate harmful acids, as well as free carbon and water.
If free carbon deposits on the exhaust valve, it not only damages its sealing performance, but also increases flow resistance.
If the stripped carbon slag is taken out of the compressor, it can block the capillary tube and dryer. Acids can corrode the components of the refrigeration system and electrical insulation materials in a 50 ton water chiller. Moisture in the compressor can block the capillary tube.
In addition, the excessive discharge temperature of the compressor in a 50 ton water chiller will directly affect the service life of the 50 ton water chiller, as the chemical reaction rate of the refrigerant in the compressor increases with the increase of the refrigerant temperature.
In general, if the temperature of electrical insulating materials increases by 10 ℃, its life will be reduced by half, and the life of electrical insulating materials is particularly important for fully enclosed compressors. Only by controlling the discharge temperature of the refrigeration compressor of the 50 ton water chiller can we better, more scientifically, and more rationally use the 50 ton water chiller.
Firstly, excessive exhaust temperature can lead to a decrease in the working efficiency of the condenser.
There are various reasons for high exhaust temperature. If the flow rate of cooling water is insufficient and the water temperature is too high for a long time, the exhaust temperature will be too high.
Once the exhaust temperature of the compressor is too high, there will be problems with the working efficiency. In addition, after the high-temperature gas is discharged to the condenser, the condenser cannot completely cool the refrigerant, which may result in liquid accumulation.
Over time, the working efficiency of the condenser will decrease, and accordingly, when the working efficiency of the condenser decreases, it will also affect the working efficiency of the compressor.
Secondly, the suction pressure is low and the suction heat is high.
When the exhaust temperature is too high, the suction temperature will correspondingly increase. Due to the high exhaust temperature of the compressor, it can be inferred that the compressor is relatively large, which is caused by the low suction pressure during the suction process.
