What are the standards of industrial freezer manufacturers for the water environment?

Industrial refrigerator is an energy-saving machine and equipment that can achieve refrigeration effect through steam compression or absorption water circulation system. So what are the water environment standards of Changzhou industrial refrigerator manufacturers? Let's take a look with the editors below!

Industrial refrigerators are all called cooling water cycle machines, also called refrigerators, chillers, freezers, chillers, ice water machines, small chillers, industrial chillers, freezers, low temperature chillers, and laser chillers. It is widely used in various manufacturing industries, so it varies according to the manufacturing industry, and its name is also countless.

Interpretation of industrial refrigerator water environmental standards

The softening of water is also a crucial issue in the process of applying industrial refrigerators. The pH value of water must also be constantly monitored. The preferred pH value should be equivalent to 7, a low-temperature constant temperature bath, which is greater than 7. The ph value will cause terrible corrosion problems. If no effective measures are taken, it will cause scale in the evaporator and mold, and it will have the effect of heat insulation. In severe cases, its energy conversion will be reduced by 30%. It is clear that this standard considers softening of hard water.

Specific method, an electronic hard water softener can be selected in the system. The softener is designed and manufactured based on the principle of exchange. According to the different flow rates, there are optional softeners with different specifications, which can be connected to the circulating water pipeline at any time. The cost of the optional water treatment softener is not too high, and it can also be used in the water circulation system for a fixed period of time. To the appropriate scale.

The root cause and treatment method of odor in the chiller operation process

1. The root cause of itself

a. Refrigerant problems, poor quality refrigerants; root cause of water environment, poor water environment, stinky water, dirt water, etc.

b. Is the line protection damaged and the line protection skin corroded or melted?

c. The compressor is damaged

d. Welding interface burned out

2. External root causes

a. Are there any items stuck in the condenser or evaporator of the unit? When the unit is activated, the temperature is high, which causes the inside contents to melt and have an odor.

b. Is the unit in a well-ventilated place?

3.Solutions for odor

a. Check the compressor, check whether it is damaged, repair \ replace

b. Application of water

c. Cleaning the condenser and evaporator

d. Clean up various foreign objects on the unit and keep the unit ventilated

Industrial freezer products are widely used in plastics, rubber and plastics, electronics, electroplating, chemicals, hardware, food, printing, papermaking, wire and cable, radiation, air conditioning, etc.

After the winter season, frost has appeared in some areas, especially in the north. When the air temperature does not reach 0 ° C, customers must pay special attention to antifreeze when the chiller is used or not. To reduce unnecessary property damage.

1: There is a drain valve at the bottom of the tube of the evaporator and condenser in the chiller. When the unit is not running, the drain valve must be opened to drain the solution or water inside the system. If the unit must be operated when the ambient temperature does not reach 0 ° C, ethylene glycol antifreeze must be added to the water.

2: When the unit is stopped and not running, the water pump or acid pump for circulating water must also open the drain valve at the bottom to drain the water clean. After the water freezes, the expansion pressure will exceed the pressure of the pump several times, which will cause the pump body and the pipeline to freeze and crack.

3: When the cooling water tower is not used in winter or in the daytime and not at night, the medium in the tower must be discharged to prevent the outside temperature in winter from being too low, which will cause the coil to freeze.

4: The water in the pipes connected to the unit must also be drained, otherwise the temperature in the pipes and fittings will freeze due to low temperature. Frozen or cracked piping may occur. Customers who have problems recommend wrapping thermal insulation on the outside of the pipe to prevent frostbite.
