First of all, before using the chiller, we must pay attention to the liquid medium in the tank. Then, the operation power supply should be determined according to the type of the chiller. The power supply should be greater than or equal to the total power of the instrument, and the power supply must be well grounded.In addition, the water chiller should be installed in a dry and ventilated place, and the water chiller should be 400 mm away from the obstacles. Finally, after using the water chiller, all switches should be turned off, the power plug should be connected, and the liquid in the tank should be sucked dry with suction ball and hose.Next, let's talk about the working principle and common system problems of chillers!
Chiller manufacturers talk about the operation principle of chillers:
Refrigeration working medium (i.e. refrigerant) absorbs the heat of the cooled substance and vaporizes into steam in the evaporator. The condensing machine continuously extracts the generated steam from the evaporator and compresses it. After being compressed, the high-temperature and high-pressure steam is sent to the condenser to release heat to the cooling medium (such as water, air, etc.) and condenses into high-pressure liquid. After being depressurized by the throttling organization, it enters the evaporator and condenses again vaporization.
Absorb the heat of the object to be cooled, so as to cycle. During heating, the refrigerant changes the flow direction of refrigerant through the four-way valve. The flow direction of refrigerant is just opposite to that of refrigeration. The refrigerant first passes through the evaporator, then returns to the condenser, and finally returns to the compressor.
The chiller can be used in matching vacuum equipment. Such chillers also meet the needs of high-quality vacuum equipment, such as molecular pump, small vacuum coater, etc.
The chiller is used in matching medical laser equipment. This kind of chiller has unique water quality treatment characteristics, which makes it an ideal choice for supporting medical laser equipment and supporting laboratory equipment. This series of chillers are also widely used in atomic absorption spectrometry analyzer, fermentation equipment, reactor, electrophoresis instrument, etc.
Water chiller manufacturers talk about common system problems
Ventilation system: check the air filter, heat exchanger coil and fin of air-cooled chiller to see if there is too much dust.Whether the air inlet and outlet are unblocked; whether the fan and fan blade work normally. Whether the wind force is normal, whether the water system is normal, etc.
Water system: check whether the water system of air-cooled chiller is leaking. Whether the water inlet and outlet are dredged; whether the water pump works normally. Listen to the power on, listen to the air-cooled chiller compressor working sound is normal, there is no abnormal sound, fan, water pump working noise, noise is not too big, etc. The air-cooled chiller has slight oscillation and low noise under normal working conditions.
Refrigeration system: check whether there are cracks, damages, frosting and condensation in the refrigeration system of the air-cooled chiller. Whether there is friction between the refrigeration pipes of the air-cooled chiller and between the pipe and the shell, especially whether there is leakage at the welding place of the refrigerant pipe and the joint of the air-cooled chiller. If there is any leakage, there will be oil stain. Clean soft cloth and paper can also be used to scrub the welding place and the joint of the pipe to investigate whether there is oil stain, so as to judge whether there is leakage.
Electrical system: check whether the fuse of the electrical system of the air-cooled chiller is fused, whether the insulation of the electrical wire is intact, whether the circuit board is cracked, whether the joint is loose, etc. Especially the electrical connection is not good touch, wiring screws, connectors are easy to loose, resulting in poor touch.
