Solution to Thermal Shock Test chamber Refrigeration System Blocking
Thermal shock test chamber is generally composed of compressor, air conditioning evaporator, cooler and pipe system software. Refrigeration system blockage generally has two kinds of dirty blockage and ice blockage, and oil blockage is relatively rare.
1. Dirty and blocked
When the compressor of thermal shock test chamber is damaged, and there is waste in the refrigeration system, this waste is very easy to block in the capillary or filter device, which is called dirty plugging. Dirty blockage is because there is residue in the refrigeration system (oxygenated skin, copper chips, welding through), when it is circulated with the refrigerant system, it causes blockage at the capillary or filter device.
Dirty blockage removal method: remove the capillary tube, filter device, cooler, air conditioning evaporator with gas cutting, disassemble the carbon molecular sieve in the capillary tube and filter device, clean the cooler and air conditioning evaporator, carry out dry, vacuum packaging, welding, and fill with refrigerant.
2. Ice jam
Ice blockage is caused by water entering the refrigeration system of thermal shock test chamber. Due to its own with a certain amount of moisture, coupled with the maintenance or refrigerant in the whole process of taking time processing regulations are not tight, so that water and gas into the system software. Under the ultra-high pressure effect of the compressor, the refrigerant is changed from a liquid to a vapor state, so that the water is passed into the narrow and long capillary tubes with the refrigerant circulation system. When the moisture content of each kilogram of refrigerant exceeds 20mg, the filter device is saturated with water, and the water can not be filtered out. When the temperature of the capillary inlet and outlet is 0 ° C, the water is converted from the refrigerant and becomes ice, resulting in ice blocking.
Dirty blocking and ice blocking are divided into full and half blocked, the common fault condition is that the air conditioning evaporator is not frosting or frosting is not full, the temperature behind the cooler is high, and the hand drying filter or capillary entrance feels that the temperature is basically the same as the indoor temperature, sometimes less than the indoor temperature, and a lot of steam is sprayed out of the cutting process pipe. After the ice jam occurs, the friction resistance of the compressor exhaust pipe increases, resulting in the compressor overtemperature, the overload protector is working, and the compressor stops running. After about 25 minutes, a part of the ice jam melts, the compressor temperature decreases, the contact point of the temperature controller and the overload protector is closed, and the compressor starts the refrigerator. Therefore, the ice blockage has regularity, and the air conditioning evaporator can see regular frosting and defrosting conditions.

Cleaning Method of Condenser in Rapid Temperature Change Test Chamber
Rapid temperature change test chamber is a kind of high-precision and high-stability experimental equipment, which can carry out temperature changes in a short time to test the performance changes of materials and products at different temperatures. It is mainly used to detect the performance of products under rapid temperature changes and limit temperature conditions, and is widely used in semiconductor chips, scientific research institutions, quality inspection, new energy, optoelectronic communications, aerospace military industry, automotive industry, LCD display, medical and other science and technology industries.
After handing over the machine to the customer, in addition to instructing the precautions of equipment operation, it will also emphasize the daily maintenance of the equipment. After a long period of operation, Rapid temperature change test chamber should pay special attention to the maintenance of the refrigeration system, because the refrigeration system is not only a complex manufacturing process but also the core of the equipment refrigeration, and the next will focus on understanding the cleaning method of the condenser in the refrigeration unit.
1, Chemical pickling and scaling
For vertical and horizontal shell and tube condensers, the chemical pickling method can be used, and the weakly acidic detergent can be prepared in the pickling tank. After the pickling pump is turned on and run for 24 hours, the pickling pump is turned off, and the circular steel brush is used to brush the tube wall of the condenser back and forth, and the water is washed until all the dirt or rust stains and the scaling solution remain in the tube are clean.
2, Mechanical scaling
First, the refrigerant in the vertical shell and tube condenser is extracted, and all the valves connected to the condenser are closed, and then cooling water is normally supplied to the condenser. Use the bevel gear connected with the flexible shaft pipe washer (the diameter of the hob should be selected to be smaller than the inner diameter of the cooling pipe to scratch the inner wall) in the condenser from the top down rotary rolling mode to remove scale, because the circulating cooling water and the friction of the pipe wall generate heat, can help dirt and rust and other dirt directly washed out of the pool. After the end of descaling, drain the water in the condensate pool, clean up the dirt, and refill the water.
3, Electronic magnetic water scaling
At normal temperature, the electron magnetic water can dissolve calcium, magnesium and other salts in the cooling water of the condenser as positive and negative ions in the water. Electron magnetic water can change its crystallization conditions, can loosen the structure, reduce the tensile and compressive capacity, so that it can not form a hard scale with strong bonding force, and is converted into loose mud with the flow of cooling water and discharged.
The above is the scientific method of cleaning the condenser dirt of rapid temperature change test chamber.
