How should the recirculating cooler be used?

Before installing or operating the LX -25°C ~ +30°C Recirculating Chillers, make sure you have read the user manual and understand the contents of the manual and some precautions listed in the manual.

Non-professional personnel are not allowed to repair the machine without permission.

The machine should be handled with care during handling, otherwise it is easy to cause looseness of internal parts of the machine and cause failure.

Please pay attention to all warning labels.

Do not remove the warning label.

Do not start the machine when there is no coolant in the water tank of the machine.

Before servicing or moving the machine, be sure to cut off the power supply of the power cord.

1. What is the working principle of the circulating cooler?

The low temperature and low pressure liquid refrigerant in the evaporator and the surrounding water carry out heat exchange. The heat absorbed by the evaporator evaporates into the low temperature and low pressure gaseous state.

The temperature of the refrigerant does not change during evaporation, so that the low temperature and low pressure gaseous refrigerant enters the compressor and becomes the high temperature and high pressure gaseous state after compression, and then enters the condenser for heat exchange with the indoor medium, and part of the heat is absorbed by the medium, Cause the medium temperature to become high.

The refrigerant releases heat from the condenser and becomes a high-temperature high-pressure liquid. The temperature does not change during this process, and then enters the expansion valve for throttling. Throttling can quickly reduce the temperature.

The refrigerant becomes a low-temperature low-pressure liquid, and then enters the evaporator again for heat exchange and evaporation. This is the total outflow of refrigeration. Note that the cycle is continuous, so the water can not stop cooling.

2. What are the preparatory tasks before starting the circulating cooler?

1) Confirm that the unit and controller are powered on.

2) Confirm that the cooling tower fan, cooling water pump and cold water pump are turned on.

3) Confirm that the end fan coil unit has been powered on.
