What is the basic pressure regulation method for water recirculating chiller?
1、 Pressure regulation concept
The working principle of a LX -25°C ~ +30°C Recirculating Chillers is to use circulating refrigerant to flow through the evaporator under high pressure in the condenser to achieve cooling effect. Therefore, the high-pressure state of the condenser is one of the key factors to ensure the normal operation of the chiller. The high pressure of the condenser is mainly determined by the pressure during compressor operation. Therefore, we need to adjust the operating pressure of the compressor to ensure the normal operation of the chiller.
2、 Manual adjustment method
To manually adjust the pressure, you need to find the adjustment button or knob on the compressor control panel and gradually adjust the operating pressure of the compressor according to the actual situation on site. The specific steps are as follows:
1. Firstly, determine the environmental parameters on site, including ambient temperature and relative humidity.
2. Find the adjustment button on the compressor control board and adjust the operating pressure of the compressor according to the actual situation.
3. Gradually adjust according to the adjusted results to achieve the desired operating state.
3、 Automatic adjustment method
For some compressors that automatically adjust pressure, users only need to set the relevant parameters, and the compressor will automatically adjust. The specific steps are as follows:
1. According to the compressor manual or user manual, set the parameters for automatic pressure adjustment.
2. Turn on the power of the chiller and wait for the compressor to run.
3. The compressor automatically adjusts the pressure to ensure the normal operation of the chiller.
When adjusting the pressure, it is necessary to adjust it according to the on-site environment and actual needs. Do not adjust it too high or too low to avoid affecting the normal operation of the chiller.
When adjusting the pressure, it is necessary to pay attention to the safety of the operation to avoid unexpected situations.
When using the automatic adjustment method, it is necessary to make reasonable settings according to the compressor manual to ensure the stability and reliability of the chiller operation.
In summary, the pressure regulation of the water circulation cooler is an important link to ensure the normal operation of the chiller. Users can use manual or automatic adjustment methods to choose according to specific situations. During operation, it is necessary to comply with relevant regulations to ensure safety and reliability.
