What should be paid attention to in the use of small water chiller?

Replace the drying filter regularly

Refrigerant and water are mutually insoluble. If the system contains water, it will greatly affect the operation efficiency of the chiller. Therefore, it is very important to keep the system dry.

Regularly inspect the safety valve

The condenser and evaporator on the LC -25°C ~ -5°C 저온 냉각기 are pressure vessels, and the safety valve can automatically relieve pressure to prevent possible harm to human body caused by high pressure.

Replace lubricating oil regularly

After long-term use, there will be impurities and moisture in the lubricating oil. Regularly observe and check the oil quality, and replace it regularly to meet the requirements.

Check the compressor regularly

The compressor is the main component of the unit, and its quality directly affects the stability of the unit in use. If the compressor breaks down, the cost is relatively high.

1. How to use small chillers in summer?

The refrigeration unit of the industrial water chiller is used for a long time, and the compressor is kept in working condition for a long time, which is easy to produce impurities to make the compressor lock up and damage the refrigeration system. Generally, the maintenance of the refrigeration unit is formulated according to the working hours of the engine. Generally, the maintenance of the refrigeration unit is conducted once every 500-700 hours.

In addition, there are many cases of continuous work during the peak construction period in summer, so it is not recommended to constantly observe the operating state of the compressor and check its exhaust temperature. During the seasonal operation, special attention should be paid to the operating state of the system, and the liquid supply and condensation temperature of the system should be adjusted in time.

2. What are the characteristics of small chillers?

During installation, the unit shall be compact in structure, which will save ground space and be light and easy to handle. Safe operation balance, small vibration, no need for complex foundation, and simple installation. Generally, various performance tests and wiring have been completed before delivery, reducing installation time and cost.

Well controlled PLC programmable controller and fully automatic computer regulation control make the group control more accurate, reliable and automatic monitoring of cold water outlet temperature. Through PLC automatic control of slide valve unloading, the compressor is automatically adjusted within a very small temperature range to reduce energy consumption.

When the unit starts, it has the self diagnosis function. When some parameters are close to the limit value, certain protective measures shall be taken and an alarm shall be given to prevent the unit from being damaged. And reduce unplanned downtime. Automatically record and save the alarm conditions and occurrence time of the last ten unit failures, and send out troubleshooting tips.
