Why would a screw chiller experience a three-phase power failure, and how can it be resolved?

There are four reasons for a screw chiller "three-phase power failure": the power is not connected, the fuse is blown, the power voltage is unstable or the phase sequence is incorrect, and the transformer is damaged. The troubleshooting methods and solutions are as follows:

Application scenarios of air-cooled and water-cooled screw chillers

Small and medium-sized building air conditioning: such as shopping malls, office buildings, hotels, etc., no need to build an additional cooling water system, easy installation (such as placing the unit directly on the roof).

How to maintain a chiller?

Maintaining and servicing chillers is crucial for ensuring their efficient operation and extending their lifespan. While different types of chillers (such as air-cooled and water-cooled) may have slightly different maintenance details, the core principles remain the same.

Cold water machine installation precautions

1. A stable base platform must be prepared before the unit is installed to ensure smooth operation. 2. Use the attachments specified by our company. The installation environment must ensure that the air is free of corrosive pollutants and has minimal oil and gas. 3. Before installation, be sure to refer to the machine nameplate power supply installation. Improper installation may cause electric shock, electric shock, and motor burnout. 4. Please install a ground fault circuit interrupter. 5. The main controller must use the same power supply system as the unit. The control data lines should be isolated from the power supply lines to prevent interference. 6. A grounding wire must be installed. Improper installation of the grounding wire may cause electric shock.

How to choose between air-cooled and water-cooled chillers?

Determine cooling capacity needs: The required cooling capacity must be calculated based on the heat generated in the actual application scenario, such as heat generated by equipment operation and ambient heat, to ensure that the cooling capacity of the selected chiller can meet the cooling needs.

How should a wind-cooled chiller be handled after load damage?

Handling methods for wind-cooled chiller load damage: First, confirm whether the compressor load is burned out or parts are worn. If so, the refrigerant system will inevitably be contaminated, such as residual refrigerant oil carbonization remaining in the pipeline, the dryer filter absorbing a large amount of water, etc.
