高温および低温の液体循環式冷凍機の運転において、氷詰まりは比較的よく見られる故障です。関連メーカーの経験に基づき、氷詰まりに対処するためのヒントを特別にまとめました。配管内の...

In the pipeline of the high and low temperature liquid circulating chiller, if ice blockage occurs, it is recommended to replace the damaged pipe section and repair the missing spot welding first, and redo and tighten the loose threaded joint. In order to ensure that there is no leakage in the high-pressure test of the high and low temperature liquid circulating water chiller pipeline. The high and low temperature liquid cycle chiller refrigeration cycle system pipeline is divided into high pressure section and low pressure section, flushed with four-recording carbon, and purged with nitrogen to seal for later use.

At the same time, the high and low temperature liquid circulating chiller compressor unit must be strictly processed in accordance with the steps, replacing the new filter of the high and low temperature liquid circulating water chiller, and then blown and sealed for use. The high and low temperature liquid circulating chiller refrigeration cycle system pipeline is unsealed and the compressor unit is quickly assembled After that, perform quantitative charging of the refrigerant, and wait for five minutes (waiting for the static equilibrium of the pressure in the high-pressure zone and low-pressure zone in the refrigeration cycle system pipeline) to power on and test the machine.

When the user usually faces the operation of high and low temperature liquid circulating chillers, they need to pay attention to moisture prevention and seal or seal the parts of the high and low temperature liquid circulating water coolers that are not being repaired. Maintenance is carried out in rainy weather.

However, there is always a case in case. For high and low temperature liquid circulating chillers with slight ice blockage after maintenance, the refrigerant can be recovered, replaced with new filters, or connected in series with a large cubic freezer filter at the high-pressure exhaust end, or even Refill the refrigerant quantitatively.

There are one or two ways to face the phenomenon of ice blockage in high and low temperature liquid circulating chillers. If the user does not know how to solve it, do not solve it blindly by himself. It is recommended to find a professional maintenance person to solve it.
