What are the adverse effects of excessive exhaust temperature of air-cooled low-temperature chillers?

High exhaust temperature is a common disease of air-cooled low-temperature chillers, and it will also bring many adverse consequences, which is unfavorable to the operation of industrial chillers
.

So what are the adverse effects of excessive exhaust temperature on industrial chillers? In fact, it is mainly reflected in the following two aspects
.

1.
High exhaust temperature will lead to a decrease in
condenser efficiency.

There are many
reasons for the high exhaust temperature.

If the cooling water flow is insufficient, the water temperature is too high for a long time, which will cause the exhaust temperature to be too high
.

Once the exhaust temperature of the compressor is too high, the work efficiency will be a problem
.

In addition, after the high-temperature gas is discharged into the condenser, the condenser cannot completely cool the refrigerant, which may cause a fluid
accumulation.

Over time, the efficiency of the condenser will decrease, and correspondingly, when the efficiency of the condenser decreases, the efficiency
of the compressor will also be affected.

2.
Low suction pressure and high
suction heat.

When the exhaust temperature is too high, the intake air temperature will increase
accordingly.

Due to the high exhaust temperature of the compressor, it can be inferred that the compressor compressor is relatively large
.

This is because the inlet pressure must be low
during the inlet.

What should I pay attention to when operating the air-cooled low temperature chiller? 1.
Can the chilled water pump run without water in the water tank? (7.
5HP or above models, the water tank is equipped with water level protection, when the water level is too low or there is no water in the tank, the pump will automatically stop running, and display the water level fault code and alarm number
.

2.
When operating the switch, please try to avoid continuous switching
.

3.
When the temperature of the frozen water reaches the set temperature, the compressor will automatically stop running
.

4.
The temperature switch shall not be set below 5 °C to prevent the evaporator from freezing, except for
the low temperature refrigerator.

5.
In order to ensure the refrigeration effect and maintain the best state, please clean the condenser, evaporator and water filter regularly
.

Note: If the air-cooled low-temperature chiller has a fault alarm, please shut down the system immediately and then turn it on after troubleshooting
.

Or notify the maintenance personnel in time to deal with it
