Causes and Treatment of Air Intake Failure of Industrial Chiller Refrigeration System
Water-cooled industrial chillers and air-cooled industrial chillers are generally used in long-term working conditions. If there is a little leakage in the refrigeration system, air will enter the refrigeration system of the industrial chiller for a long time. The low-temperature refrigerant in the refrigeration system will not condense into liquid with the heat dissipation of the air, which will affect the heat dissipation effect of the condenser and cause the condensing pressure to rise, causing the industrial chiller to fail to operate normally. Therefore, it is necessary to discharge the air in the industrial chiller to maintain the normal operation of the industrial chiller. 1. Operation steps of industrial chiller deflation in Freon system 1. Close the outlet valve of the accumulator or the outlet valve of the condenser; 2. Start the compressor and put the refrigerant in the low pressure section into the condenser or accumulator; 3. Stop the machine after the pressure of the low-pressure system drops to a stable vacuum state; 4. Loosen the screw plug of the bypass hole of the exhaust stop valve, turn it about half a turn, and the exhaust valve stem will make the valve into a three-way shape, so that the high-pressure gas can escape from the bypass hole. Block the exhaust air with the palm of your hand. When the hand feels cold and there are oil stains on the hand, it means that the air has basically been exhausted. Tighten the screw plug, reverse the exhaust valve stem, and close the bypass hole. 5. It should be noted that each deflation time should not be too long, and it can be carried out 2 to 3 times in a row to avoid wasting the refrigerant. If the top of the condenser or accumulator is equipped with a spare shut-off valve, the air can also be released directly from the valve. 2. Operation steps of industrial chiller deflation of refrigerant refrigeration system 1. When using the air separator to release air, put the return valve of the air separator in the normally open state to reduce the pressure of the air separator to the suction pressure, and other valves should be closed. 2. Properly open the mixed gas inlet valve, so that the mixed gas in the refrigeration system of the chiller enters the air separator. 3. Slightly open the liquid supply valve, so that the refrigerant is throttled into the air separator to vaporize and absorb heat, and cool the mixed gas. 4. Connect one end of the rubber hose to the air release valve interface into the water in the water container. When the refrigerant in the mixed gas is cooled into ammonia liquid, frost will form at the bottom of the air separator. At this time, the air valve can be slightly opened to discharge the air through the water container. If the bubbles are round in the process of rising in the water and there is no volume change, and the water is not turbid and the water temperature does not rise, then air is released. At this time, the opening of the air release valve should be appropriate. 5. The refrigerant in the mixed gas is gradually condensed into refrigerant liquid and accumulated at the bottom. The liquid level height can be seen from the frosting of the shell. When the liquid level reaches 12, close the liquid supply throttle valve and open the liquid return throttle valve. The bottom refrigerant liquid is returned to the air separator to cool the mixed gas. When the bottom frost layer is about to melt, close the liquid return throttle valve and open the liquid supply throttle valve. 6. When stopping the air release, first close the air release valve to prevent the refrigerant from leaking out, and then close the liquid supply throttle valve and the mixed gas intake valve. To prevent pressure build-up in the air vent, the return valve should not be closed. 3. Refueling method of rotary compressor of industrial chiller When adding refrigeration oil to the rotary compressor, first seal the low pressure pipe of the compressor (or close the low pressure valve), and pour the refrigeration oil into the oil cup. Connect the middle hose of the compound pressure gauge to the high-pressure exhaust pipe of the compressor, connect the high-pressure hose of the compound pressure gauge to the vacuum pump, and insert the low-pressure hose into the oil cup. First start the vacuum pump, after the inside of the compressor is evacuated, then close the high pressure valve of the compound pressure gauge. Then open the low pressure valve of the compound pressure gauge, so that the refrigeration oil in the oil cup is sucked into the compressor. When the oil suction reaches the specified amount, close the low pressure valve and stop refueling.

chiller manufacturing
Chillers are divided into air-cooled chillers and water-cooled chillers in the industry. The chillers are divided into low temperature chillers and normal temperature chillers in terms of temperature control. The normal temperature is generally controlled within the range of 0 degrees to 35 degrees. The temperature control of the low temperature machine is generally in the range of 0 degrees to minus 45 degrees. When the chiller refrigerant circulates in the system, the liquid refrigerant in the evaporator absorbs the heat in the water and starts to evaporate. A certain temperature difference is formed between the final refrigerant and the water, and the liquid refrigerant is also completely evaporated into a gaseous state and then sucked in by the compressor and evaporated. Compressed, the gaseous refrigerant releases heat through the condenser, condenses into a liquid, and after being throttled through the thermal expansion valve, becomes a low-temperature and low-pressure refrigerant and enters the evaporator to complete the refrigerant circulation process.

What is the working principle of the chiller
If you want to use, operate, or maintain a chiller, or work in the refrigeration industry, then you need to have a general understanding of water-cooled chillers first. Understanding chillers begins with the general workflow and important components, as detailed below. Approximate workflow of a chiller. First exclude the water-cooled chiller, air-cooled chiller does not say, this is only the condenser heat dissipation, cooling mode to classify, here the chiller workflow, whether it is air-cooled or water-cooled are the same. 1, from the start of the chiller said, the compressor will be inhaled from the refrigerant, from the suction pipe inhaled low temperature and low pressure refrigerator gas, and then compressed, compressed words will make the refrigerant heat and pressure will become higher, according to the compression ratio and all kinds of compressors, compression results are different. 2, after the completion of compression, the compressor will be discharged from the exhaust pipe has been compressed, has become a high temperature and high pressure of refrigerant gas. When the refrigerant into the condenser, the condenser began to play a role, the condenser will not actively work, it is only because the compressor discharged gas and passive work, is a machine rather than a component, the role of the condenser is to condense, that is, to cool the refrigerant, the condenser will be high temperature and high pressure gas refrigerant heat dissipation cooled to liquid. Its working method is to dissipate heat through the copper tube of the condenser itself, and spread the heat of the copper tube (actually the heat brought to the refrigerant by the compressor and the heat of the refrigerant itself) through water cooling or air cooling. According to the different of air-cooled and water-cooled chiller, the cooling medium of condenser can be water or air (air-cooled). 3, has been cooled refrigerant, will be through one of the important parts of the chiller throttle valve, after which the refrigerant will be throttled into low pressure and low temperature refrigerant liquid. 4, refrigerant liquid will enter the evaporator, the purpose of entering the evaporator is to absorb the heat of the target equipment, heat absorption will be vaporized, refrigerant from the liquid into a gas again, after the system recovery, again into the compressor, in order to recycle. Refrigeration process important components, basically is the evaporator, compressor, condenser, expansion valve that is the throttle valve. The role of the compressor is to compress the refrigerant gas, and the condenser is to be compressed by the high temperature and high pressure refrigerant cooling into a medium temperature and high pressure liquid refrigerant, refrigerant temperature is moderate but the pressure is still relatively high, through the expansion valve (throttle valve) can become a lower pressure, temperature is correspondingly lower refrigerant liquid, after entering the chiller evaporator to play the role of cooling target equipment or objects. Toyo's chillers are made of imported, high quality parts, which ensure the efficient and high quality operation of the chiller.

How do chillers work HVAC?
Q:how does chiller work A:A chiller works on the principle of vapor compression or vapor absorption. ... As the heat-transfer takes place, the refrigerant evaporates, changing from a low-pressure liquid into vapor, while the temperature of the process coolant reduces. The refrigerant then flows to a compressor, which performs multiple functions. Q:how to chiller work A:How Does a Chiller Work? A chiller works on the principle of vapor compression or vapor absorption. Chillers provide a continuous flow of coolant to the cold side of a process water system at a desired temperature of about 50°F (10°C). Q:where to buy chiller machine A:We have 30 years of experience in design, development and production. State-level high-tech enterprises, appearance, use of new-type patents.Air-cooled chillers are widely used in electronics, electroplating, food, machinery, chemical, laser, card making, medical and other industries. Because the source of its heat exchange is gas, it is equipped with a dedicated electric fan, so it is called "air cooling". The air-cooled chiller is mainly used for plastics. It can accurately control the temperature of plastic forming molds to shorten the molding cycle and accelerate product setting. This series uses the principle of cold and heat exchange for cooling, which can quickly cool down and stabilize the temperature control. It is not affected by environmental factors and is an indispensable configuration device in modern industry.

Low temperature water chiller maintenance and care
Low-temperature chillers are characterized by a lower refrigeration range compared to medium-temperature chilled water or ordinary chillers, which can be as low as minus tens of degrees Celsius or even below minus 100 degrees Celsius, the refrigeration efficiency of the compressor, the electrical resources required for refrigeration are higher than ordinary or Chinese chillers, in terms of maintenance, maintenance, low-temperature chillers to be more tricky. Take the explosion-proof low-temperature chiller of Lingtong Refrigeration as an example, it adopts the world famous brand compressor, and due to the characteristics of explosion-proof low-temperature chiller, the unit must be confirmed before leaving the factory, it can operate under the harsher environment without problems. The explosion-proof low-temperature chiller produced by Lingtong Refrigeration can be used in flammable and explosive special occasions, and customers can even choose different explosion-proof levels according to the actual needs, and the price of Lingtong Refrigeration's explosion-proof low-temperature chiller varies according to the different explosion-proof levels. As mentioned above, the maintenance of low-temperature chillers is not simple, but the low-temperature chillers produced by Lingtong Refrigeration Equipment Co., Ltd. have a relatively low failure rate due to the use of internationally renowned compressors and other components, and have various advantages such as energy saving and environmental protection, good performance, low noise, so maintenance is much simpler than other similar machines. The length of use of low-temperature chillers, according to the components, especially the main components of the length of use, but in addition to whether the components have high quality, the correctness of maintenance, frequency and other factors, is also a decisive factor in the stability of the operation of low-temperature chillers, the length of use. Most low-temperature chillers use R22 refrigerant, so in the refilling and maintenance of refrigerant, the same method as the ordinary R22 refrigerant industrial chillers. Low-temperature chiller refrigerant carrier according to the different needs of use, can be divided into a variety of different types, including the most common industrial chiller refrigerant carrier - water. When the low-temperature chiller makes a strange noise, noise rises, the cooling capacity drops, the temperature rises, should pay special attention, even if most manufacturers of low-temperature chillers are equipped with computer control systems, alarm systems, explosion-proof low-temperature chillers are also equipped with explosion-proof circuit systems, etc., but in the first time the problem is found, it should still be dealt with in a timely manner, so as not to turn small problems into big problems. Low-temperature chillers are characterized by more complex and higher environmental requirements than ordinary industrial chillers, want to save on maintenance, maintenance, you should compare more from the purchase and selection, choose low failure rate, simple installation and use, high safety factor of low-temperature chillers!

Some Industrial Air/Water cooled chiller FAQ,Solve your doubts.
Q : How to anti-freeze for a laser system water chiller? A : Three tips to guard your chiller through winter. "Working 24 hours" Run the chiller for 24 hours per day and make sure the water under recirculation status. "Empty the water" Empty the water inside the laser, laser head and chiller after done with using. "Add antifreeze" Add antifreeze into the water tank of chiller. S&A recommends the antifreeze which is exclusive used for automobile. Note: all kinds of antifreeze contain certain corrosive property, not to be used for long period. Please use clean pipes with deionized water or distilled water after winter, and refill deionized water or distilled water as the cooling water. Warm Note: because antifreeze contains certain corrosive property, please dilute it strictly according to usage note before adding into cooling water. Antifreeze Tips Antifreeze usually uses alcohols and water as base with high boiling point, freezing point, specific heat and conductivity for anti-corrosion, anti-incrustant and rust protection. Three important principles of chillers antifreeze need to aware during usage. 1. The lower concentration the better. As most antifreeze with corrosiveproperty,the concentration will be the lower the better under condition of antifreeze requirement meet. 2. The shorter usage period the better.Antifreeze will deteriorate after long time use, the corrosive will stronger and viscosity will change. So need to replaceregular, recommend to replacing after 12 months usage.Use pure water at summer, and replace new antifreeze at winter. 3. Don`t mix up. Better use the same brand antifreeze. Even the main components are the same for different brandsantifreeze, the additive formulas are different, so don`t suggest combine different brands antifreeze, in case chemistry reaction, sediment or air bubble happen. Q : Chiller turned on but unelectrified A : Failure Cause: A. Power cord is not plugged in place Approach: Check and ensure the power interface and the power plug is plugged in place and in good contact. B. Fuse burnt-out Approach: Replace the protective tube in the power socket on the back of chiller. Q : Flow Alarm (controller displays E6)use a water pipe directly connect to the water outlet and inlet but still without water flowing A : Failure Cause: Water level in the storage water tank is too low Approach: Check the water level gauge display, add water until the level shown in the green area; And check whether water circulation pipe leaks. Q : Flow Alarm occurs while running with other equipment (controller displays E6),but there is water flowing and no alarm whten use a water pipe directly connected to the chiller water outlet and inlet. A : Failure Cause: Water circulation pipes are blocked or a pipe bending deformation. Approach: Check water circulation pipe Q : Ultra-high temperature alarm A : Failure Cause: A. Blocked dust gauze, bad thermolysis Approach: Unpick and wash the dust gauze regularly B. Poor ventilation for air outlet and inlet Approach: To ensure a smooth ventilation for air outlet and inlet C.

How to Choose the Right Water Chiller
How should I choose a heat pump chiller? I think this is no longer an issue for users who have used chiller units, and sizing is no longer an issue. But for users who are going to buy a heat pump chiller for the first time, they are not familiar with this area and may not know what size chiller unit to use. So, how do we match the chiller unit that is most suitable for you? After reading the article below, you should know it! Heat pump chiller can be divided into air-cooled chiller and water-cooled chiller according to different heat dissipation methods, which can control the temperature between 5-35 degrees, while the low-temperature chiller can control the temperature between 0-40 degrees. For the selection of the chiller we need to correctly understand the chiller's inlet water temperature, how much water temperature, how much flow, how big the tank, etc., but also the chiller's working environment has a clearer understanding of the chiller, such as the amount of ambient temperature, the seasonal changes in ambient temperature, environmental space. Temperature, the return water temperature refers to the cooling water temperature, some heat dissipation requirements of more stringent requirements of the equipment will have cooling water supply temperature requirements; water pressure: some need to heat dissipation equipment due to the complex internal heat dissipation structure of the equipment, cooling water supply has certain pressure requirements, then need to consider whether the chiller's rated water pressure can meet the requirements. Pump head: If it is a single machine used one to one, the pump head should not be a problem. If multiple water-cooled chillers are connected in parallel to form a system for the application of multiple cooling equipment, the resistance of the piping system should be taken into account, from which it is estimated how large a pump head needs to be configured; control and regulation requirements: generally refers to pressure control and temperature control and regulation; chiller set safety protection function requirements: A. compressor delayed start protector B. high and low voltage protection function C. reverse phase protection D. compressor overload protection E. anti-freezing protection F. compressor overheating protection G. compressor frequent start protector and abnormal indicator and various protection switches.

Chiller system in the role of the filter and cleaning methods
The filter is very important in the chillers produced by the chiller plant, what is the specific role of the filter? In the chiller system, the filter plays the role of filtration, but it looks like a simple filtering job, but it's not simple at all. The filter can play a role in filtering impurities, its purpose is to reduce or eliminate the possibility of impurities in the chiller system, once the chiller system into the impurities or foreign matter, it will cause the chiller operating efficiency reduced, cooling capacity, temperature rise, compressor load becomes high, serious, but also trigger the chiller's protection device, causing the compressor shutdown or even system damage. Both air chillers and water chillers need filters. The filter, also known as a filter by the chiller plant technicians, is in most cases used to filter out impurities and foreign matter, and used along with the filter is a dryer, which ensures that moisture is avoided from entering the chiller system, and that the system does not suffer from ice blockage or other problems due to moisture entering the system. The main components of the filter are the cartridge and the dryer is the desiccant, and together they are used as a filter drier to filter out the magazines and the moisture that may enter the chiller system, that is, to protect the normal operation of the chiller system. Air-cooled chiller is relatively more dependent on the filter cartridge, because of the characteristics of air-cooling decision: air-cooled that is, the fan system, because of the air cooling method of heat exchange, so in the continuous operation of the fan process, the dust and foreign bodies in the surrounding environment will be continuously inhaled into the chiller, if there is no protection of the filter cartridge, these foreign bodies or dust will inevitably enter the air-cooled chiller system, causing damage to the machine, affecting normal production. Whether water-cooled, air-cooled, you should pay attention to the filter drier, aligned for regular replacement, if the maintenance cost is limited, you should clean the filter, blow dry desiccant. The installation position of the filter drier is mostly in the middle of the refrigerant storage tank and expansion valve (or capillary tube) of the chiller, which can filter the refrigerant as well as the magazine "given" to the refrigerant in the system and the moisture that may be brought into the refrigerant, so as to prevent ice blockage and prevent the water from entering the compressor with the system and causing various problems. As for how to clean the filter drier, the chiller plant recommends using a high-pressure air gun to blow it out, preferably replacing it directly.

The motor compressor unit includes an electric motor that drives a compressor and may be arranged in a semi-hermetic or hermetic encapsulation. In an hermetic encapsulation, the electric motor is located outside a suction gas stream flowing into the compressor and outside a discharge gas stream exiting from the compressor so that the electric motor is only exposed to an essentially static ammonia atmosphere. The motor-compressor unit and the semi-hermetic encapsulation are composed of materials stable or resistant to ammonia.
