A chiller can be regarded a cooling system that cools materials down by removing heat from a liquid via a vapor-compression or absorption refrigeration cycle. The liquid gets circulated through a heat exchanger to cool equipment. In a chiller system, there is always a liquid working as a refrigerant going through the heat exchanger in order to transfer the heat energy. When the heat gets absorbed by the liquid, materials get chilled.
Chiller Plant Safety You Need to Notice
During the working process of a chiller, there are some tips you need to pay attention to:
- Do not apply water to the equipment to avoid the risk ofdisconnection and electric shock.
- If installation ground wire is not grounded, there is a danger of electric shock.
- Do not use in a hot, humid, corrosive environment.
Why does a Chiller Trip?
Some users wonder why a chiller just suddenly trips during the operating. It is because the workload of the chiller is too much because of the huge changes of the process or the ambient temperature. Therefore, a blown circuit breaker or fuse can be a protection for it.
How do You Maintain a Chiller Plant?
The maintenance and care is crucial for a chiller’s operation. Good maintenance can make a chiller’s life longer. There are some tips that can help to maintain a chiller plant:
- Prevent inefficiencies caused by non-condensables.
- Keep tubes clean for efficient heat transfer.
- Maintain adequate refrigerant charge.
What is Chiller Plant Approach?
In terms of temperature control, it is divided into low-temperature industrial chiller and normal-temperature chiller. The temperature of the normal temperature unit is generally controlled within the range of 0-35 degrees. Low temperature unit temperature control is generally between 0 degrees and -100 degrees.
What is Chiller Plant Safety?
Safety is an important issue in a chiller’s usage. We all know that the pump needs ventilation to prevent the body from overheating. Therefore, the location where the pump is installed must ensure adequate ventilation and prevent the risk of fire. This means that all pump types except submersible pumps must be installed at least three feet away from walls and other equipment. In addition, the exhaust gas discharged from the water pump contains carbon monoxide, which is a toxic and odorless gas, a by-product of incomplete chemical reactions.
How do You Start a Chiller Plant?
The dilution of antifreeze must be controlled. The higher the concentration, the damage to the pump shaft seal may occur. In addition, the antifreeze cannot be used for a long time. When the weather warms up, the water will not freeze. The water in the original water tank must be drained and replaced with pure water.
