Shenzhen Dongyuejin Chiller Factory analyzes four situations that cause the condenser surface temperature to rise: This is a Water-cooled condenser. It is mainly used in water-cooled chillers. Its role is to discharge the high-temperature refrigeration discharged by the compressor. The agent vapor condenser is a liquid refrigerant, and is an important equipment for the central heating of the refrigeration system. It is one of the four components of the chiller, and its quality directly affects the cooling capacity and the cooling efficiency.

In the working process of the water-cooled chiller refrigeration system, the outer surface temperature of the condenser is generally close to the normal temperature, and it does not feel hot when touched. Once the surface temperature is found to be too high, the cause should be identified and measures taken to eliminate it. Under normal circumstances, the cause of the rise in the temperature of the condenser is mainly the problem of cooling water. There are usually four situations:
1, the cooling water inlet pipe and outlet pipe installed wrong. The normal installation position is generally low inlet pipe, high outlet pipe, and "low in and out". If the inlet pipe is in a high position, the cooling water may not be fully contained in the condenser, and the heat transfer area will become smaller. The agent vapor is not effectively condensed, causing the condenser surface temperature to rise.
2. The poor quality of the cooling water leads to fouling on the inner wall of the cooling water pipe in the condenser, which increases the thermal resistance, affects the heat exchange between the refrigerant and the cooling water, and reduces the heat transfer effect. This type of failure often occurs in chillers that are used for long periods of time and are not regularly cleaned. The solution is to remove scale.
3, lack of cooling water, water pressure is not enough. The water-cooled condenser is the latent heat released by the cooling water to take away the refrigerant vapor condenser, so the cooling water pressure is not enough, the flow rate does not meet the rated requirements, the cooling capacity will be limited, and eventually cause the condenser surface temperature to rise .
4, the cooling water temperature is too high, higher than the rated operating temperature (usually 32 °C). The higher the cooling water temperature, the smaller the refrigerant cooling temperature difference, and the smaller the heat transfer amount, the refrigerant will not be effectively cooled, and the condenser surface temperature will increase.

A customer of a keyboard and mouse at Dongyuejin Chiller Factory was a 20p water-cooled chiller bought in 2011. At that time, Dongyue entered the installation. The cooling effect was always good, but in the middle of this month, they reflected that the chiller was not cooled ( For details, please refer to "The reason why the temperature of the water-cooled chiller does not fall down.") After arranging after-sales service personnel, you can't see it. You can't help but see that because the water quality is too bad, not only is the cooling water pipe inside the condenser. Scale, the pipeline of the entire refrigeration system has scale, the cooling water basin also has algae.

Therefore, Dongyuejin Refrigeration is here to remind new and old customers that we are not installing the chillers so that they can be refrigerated. In the process of use, we must also do a good job of cleaning and maintenance. This will not only stabilize the cooling effect of the unit, but also improve Refrigeration efficiency, make your chillers more durable!
