Precautions for chiller cooling system in low temperature operation test

There are certain differences in the use method, function, structure, etc. of different types of chiller cooling systems for low-temperature operation test.

The chiller of the industrial low-temperature operation test requires heat to be generated during operation. The cooling air should be circulated. There should be a certain space around the installation, and the generated heat should be dissipated upwards, so do not install it around equipment that is not heat-resistant. The chiller of the industrial low-temperature operation test cooling system should be installed directly on the horizontal surface. Do not install it upside down, diagonally or vertically.

The chiller cooling system for industrial low-temperature operation test cannot be installed in places where there are various fibers, paper (chips), metal fragments, etc. The water outlet of the chiller cooling system for industrial low-temperature operation test should be connected with the water inlet of your instrument, and the water outlet of the instrument should be connected with the water inlet of the cooling circulating water machine.

Check whether the air filter, heat exchanger coils and fins of the air-cooled low-temperature operation test cooling system chiller are too dusty. Is the air inlet and outlet dredged? Is the fan and fan blade working normally? Is the wind power normal? Is the water system normal?

Check if the chiller water system of the air-cooled low-temperature operation test cooling system is leaking. Is the water inlet and outlet dredged? Is the pump working normally? Listen to the power on and listen to the air-cooled low-temperature operation test cooling system chiller compressor working sound is normal, whether there is abnormal sound, whether the electric fan, water pump is noisy, whether the noise is too loud, etc. The chiller of the air-cooled low-temperature operation test cooling system is in operation, and under normal conditions, the oscillation is slight and the noise is small.

Check the air-cooled low-temperature operation test cooling system chiller refrigeration system for cracks, damage, frost and condensation and other conditions in the pipes. Whether there is friction between the chiller refrigeration pipes of the air-cooled low-temperature operation test cooling system, the pipes and the shell, etc., especially the welding place of the refrigerant pipe, and whether there is the connection of the chiller joint of the air-cooled low-temperature operation test cooling system Leakage, as long as there is a leak, there will be oil stains. You can also use a clean soft cloth or soft paper to scrub the welded joints and joints of the pipeline, and investigate whether there is any oil stains to determine whether there is a leak.

Check whether the electrical system fuse of the air-cooled low-temperature operation test cooling system chiller is blown, whether the insulation of the electrical wire is intact, whether the circuit board is cracked, whether the connection is loose, etc. Especially if the electrical connection is excellent in touch, the wiring screws and connectors are easy to loose and cause poor touch.
