9 parameters and 6 selection factors for the operation of chiller units

Water chillers, especially those used in industrial manufacturing, usually have advantages such as intelligence, energy conservation, and wide applications. By understanding and mastering the normal operation signs and cooling capacity adjustment methods of the managed water chillers, it is the foundation for mastering the use of the unit. It is also the basis for adjusting the operating parameters and cooling capacity of different models and models of water chiller units. When operating the chiller, the following points should be noted:

The inlet and outlet volume, temperature, and pressure of chilled water in the evaporator;
Temperature and pressure at the inlet and outlet of capacitor cooling water;
The pressure and temperature of refrigerant in the evaporator;
The pressure and temperature of refrigerant in the condenser;
Host current and voltage;
Lubrication pressure and temperature;
The unit operates smoothly without any abnormal noises;
Whether there is leakage in each valve of the unit;
Whether the connections of each pipeline are tight.

Improper selection of chiller units can result in unsatisfactory cooling performance, energy waste, and other issues. Therefore, understanding the basic selection knowledge of chillers is very necessary for enterprise producers. Enterprise technical personnel should choose a suitable chiller solution based on the current production situation of the enterprise.
1. What is the temperature difference you are requesting?
How many materials should be cooled and how long should they be cooled to what degree? An important reference for the selection of chillers.

2. Consider the solution that minimizes energy consumption.
Pay attention to energy consumption and choose chillers that comprehensively utilize electricity, heat, and cold, such as water-cooled screw heat recovery units, which can recover the previously discarded condensation heat and achieve dual functions such as refrigeration and heating. This can achieve both energy-saving and emission reduction goals.

3. Do chillers need to work together?
It requires multiple chillers, such as a cold storage, to achieve stable and continuous cooling. If a chiller malfunctions, alternative work from other chillers is required.

4. Are there any environmental requirements?
When the cooling water machine is in operation, it can also generate some environmental problems, such as whether the refrigerant is toxic and the operating noise is not loud, which can affect the surrounding environment of the enterprise.

5. Cooling water quality requirements.
The water quality of cold water can affect the cleanliness of pipelines, especially evaporators. Poor cooling water quality can accelerate pipeline scaling and corrosion, causing evaporator blockage and damage.

6. Other special requirements such as explosion-proof and vibration.
The working environment of cooling water equipment is harsh and often comes into contact with special substances such as flammable dust and explosive gases. Therefore, the enterprise will have higher requirements for its explosion-proof and vibration prevention. At this time, it is necessary to consult the relevant technical personnel of the enterprise to determine whether the working environment of the chiller is a special substance such as flammable dust and explosive gases. The enterprise will also have higher requirements for its explosion-proof and vibration prevention. At this time, it is necessary to consult the relevant technical personnel of the enterprise to determine whether the working environment of the chiller is a flammable and explosive environment that matches the explosion-proof requirements of the chiller manufacturer.
