​Defense measures and solutions for ultra-high temperature alarms in chillers

In high temperature weather, the high-pressure alarm of the chiller caused the production to fail, mainly because the high temperature of the radiator (cooling water) caused the high-pressure alarm of the chiller. When the water temperature of the chiller is too high, it means that the water in the water tank exceeds the set value during the operation of the chiller, and the water tank continues to rise. And the ultra-high temperature alarm of the chiller can generally be divided into high pressure alarm and water temperature ultra-high temperature alarm.

The following are the defense measures for the high-pressure alarm of the chiller in high temperature weather:

1. The dust-proof net is blocked and the heat dissipation is poor, so the dust-proof net can be removed and cleaned regularly;

2. Too much refrigerant needs to be vented.

3. The air outlet or air inlet is poorly ventilated, and it is necessary to ensure that the air outlet and air inlet are smooth;

Then check the pressure gauge, check the valve, check the pressure relief device, decompression operation, check the fault and other reasons. If the high pressure alarm still exists, you need to check whether the equipment is faulty. If the pipeline leaks, etc., repair or replace it according to the specific situation. damaged parts. Or stop using the machine and seek professional help.

When a high temperature alarm occurs, the following solutions can be taken:

1. Stop heating: When the water temperature exceeds the set high temperature threshold, stop the heater or water heater immediately to avoid further raising the water temperature.

2. Lower the water temperature: add cold water to the hot water to lower the water temperature; it can be realized by adjusting the mixing valve or opening the valve to supply cold water. If the chiller is switched on and off frequently, it is necessary to ensure that the chiller has sufficient cooling time (more than five minutes);

3. Check the equipment: Check the working status of the heating equipment and the setting of the thermostat to ensure the normal operation of the equipment.

4.Check the sensor: check the accuracy and connection status of the temperature sensor, if there is a problem, you can replace or reconnect the sensor.

5. If the heat load exceeds the standard, it is necessary to reduce the heat load, or choose a model with a larger cooling capacity

6. Cleaning equipment: Regularly clean the heating equipment to prevent the accumulation of scale from affecting the heat dissipation performance of the equipment.

7. Replacement of equipment: If the ultra-high temperature alarm occurs repeatedly, it may be that the equipment is aging or malfunctioning. It is recommended to replace the new equipment or seek professional maintenance.

If none of the above methods can solve the problem of the high temperature alarm of the chiller, it is recommended to contact the manufacturer or professional maintenance personnel for inspection and maintenance. Do not disassemble or repair the device without permission to avoid further damage or safety risks.
