Several Common Faults of Chiller Compressor

If the voltage is normal, check the static resistance. Whether the static resistance voltage is balanced and stable. If the resistance is unbalanced, see if the motor unit is short-circuited. Is there a problem with the winding. If the resistance is stable, see if the temperature of the compressor is also stable. If the temperature is too high, it should be cooled for a period of time. 2-3 hours to try again.

Adjustment of expansion valve of chiller

Whether it is an air-cooled chiller or a water-cooled chiller, the adjustment of the thermal expansion valve is to adjust the pressure of the spring by adjusting the adjusting rod, that is, to adjust the static assembly superheat of the expansion valve. The adjusting rod is rotated inward to compress the spring; The adjusting rod is rotated out to relax the spring. Clockwise rotation of the adjusting lever is to rotate in, counterclockwise rotation adjustment is to rotate out.

Explanation of high pressure fault of cold water machine

Chiller high pressure fault explanation: condenser fouling or blockage. Condensate water is generally tap water, which is easy to scale when it is above 30 ℃, and because the cooling tower is open and directly exposed to the air, dust and foreign matter can easily enter the cooling water system, causing the condenser to be dirty and blocked, the heat exchange area is small, The efficiency is low, and it also affects the water flow. The performance is that the pressure difference between the inlet and outlet water of the unit, the temperature difference becomes larger, the upper and lower temperatures of the condenser are very high when touched by hand, and the copper pipe of the condenser is hot.

Inspection and Maintenance of Auxiliary Fittings of Industrial Chiller

Although the failure rate of the core parts of the cold water machine is very low, the stable operation of the cold water machine is inseparable from various auxiliary accessories. Due to the auxiliary accessories have a service life, in order to ensure that the industrial cold water machine is in a long-term and efficient operation state, want enterprises to pay attention to the regular inspection and maintenance of various auxiliary accessories. If the auxiliary parts are faulty, you want to replace them in time to avoid the safe and stable operation of the entire cold water machine due to minor faults.

Advantages of single loop variable flow air-cooled chiller system with controlled operation

At present, the design of variable water air-cooled chiller system generally adopts the 1. secondary double-loop mode. The use of two water pumps to increase equipment investment; The mixing of water supply and return of air-cooled chillers affects the efficiency of the chiller at part load. When the actual high-load air conditioning demand conditions do not match the * * * design working conditions, the full load capacity of the chiller cannot be fully utilized and other adverse consequences. The above problems can be avoided by designing a single-loop air-conditioning air-cooled chiller system. The strengths and possible problems of the single-loop variable flow system are discussed, and a safe, stable and reliable control strategy for the chiller is provided over the entire operating range.
