How does an industrial chiller work, a chilled industrial chiller?

The form of the interface is to access the management computer through a 485 bus. Of course, before connecting to the computer, you must first connect to a multi-serial card (similar to a discrete graphics card, which must be installed on the computer case). This is the form of wiring.

Make sure you want to be a gateway and open the protocol.

Industrial chillers can generally control the water temperature at 5-35, but the specific setting of water temperature depends on the needs of the equipment, such as the water temperature requirements of fiber lasers will be stricter than the water temperature requirements of spindle engraving machines, which requires more accurate temperature control. Set the water temperature at 20-30 degrees and the cooling effect will be better.

The applications of industrial chillers cover many industries such as laser cutting, laser welding, engraving, UV printing, laboratory and medical. The chiller manufacturers on the market are also uneven, how should we screen the chiller manufacturers?

5. After-sales service.

Industrial chiller is a kind of loose fiber equipment used for refrigeration, and its main function is to cool water or other liquid substances, so as to be used in industrial manufacturing, building air conditioning and other fields.

Specifically, the functions of industrial chillers include:

Cooling the process: Industrial chillers can improve productivity and quality by reversing the surface of the processed material or equipment for cooling, which is necessary in many industrial manufacturing processes. For example, it is used in plastic screen printing machines, injection molding machines, electronic chip cooling, etc.

Provide cold water for air conditioning system: Industrial chillers are the main components of air conditioning and air conditioning systems in large commercial and office spaces, they transmit the cooling effect through air or water, so that the air temperature is lowered, so as to provide cold air to the building and keep the indoor temperature comfortable.

Provide cooling for mechanical equipment: In some mechanical equipment that needs to be cooled, such as heaters, electrical control cabinets, frequency converters, electric motors, etc., they need to be cooled by cooling water. Industrial chillers can provide cooling water for these devices and keep the temperature of the equipment stable.

Help control humidity: Some specific applications require controlling the humidity of the air, such as in the printing and textile industries, where chillers can control indoor humidity by providing cold water.

You can understand the industrial chiller with temperature control in Zhongneng and the quality is guaranteed!

Hello, Huang Gong of the technical department of the source manufacturer of the Kaideli chiller will answer for you, 1. Air conditioning engineering, the power of household air conditioning is very small, so for large shopping malls, office buildings, and factories, if you use small air conditioners, it is not possible to use our first air conditioning system, and the main unit used in the air conditioning system is the chiller.

2. Petrochemical industry, organic synthesis, organic synthesis, separation, crystallization, concentration, liquefaction, and control of reaction temperature in basic chemical industry are all inseparable from refrigeration.

3. Machinery and metallurgical industry, coating machine, injection molding machine, laser equipment, wire cutting machine, etc.

4. Food workers guess the sock process, food is perishable, seasonal, cold storage is used to store food, and the main host group of cold storage uses chillers.

5. Construction and water conservancy, in the construction industry, especially for large-scale Suichang concrete components, the exothermic heat in the solidification process is easy to crack, so the chiller is required to provide low-temperature chilled water to cool down and promote rapid solidification, which can be searched to get more relevant information.

The refrigeration working fluid absorbs the heat of the cooled object in the evaporator and vaporizes it into steam, the compressor continuously extracts the generated steam from the evaporator and compresses it, and the compressed high-temperature and high-pressure steam is sent to the condenser and then released to the cooling medium (such as water, air, etc.) and condensed into a high-pressure liquid.

After being depressurized by the throttling mechanism, it enters the evaporator, vaporizes again, absorbs the heat of the cooled object, and so on. During heating, the refrigerant changes the direction of refrigerant flow through the four-way valve, and the direction of refrigerant flow is just opposite to that of refrigeration, and the refrigerant passes through the evaporator first, then back to the condenser, and finally back to the compressor.

Three questions about industrial chillers, Ou Neng Machinery will answer for you!

Basic knowledge of industrial chillersFirst question: What is an industrial chiller?

Industrial chiller is a kind of water cooling equipment, and industrial chiller is a kind of cooling water equipment that can provide constant temperature, constant flow and constant pressure.

Second question: What is the structure of the industrial chiller?

The structure of the industrial chiller is the operation of the industrial chiller system through three interconnected systems: the refrigerant circulation system, the water circulation system, and the electrical automatic control system.

Q3: How does the cold circulation system of industrial chiller work?

1. Refrigerant circulation system: the liquid refrigerant in the evaporator absorbs the heat in the water and begins to evaporate, and finally a certain temperature difference is formed between the refrigerant and the water, and the liquid refrigerant is also completely evaporated into a liquid state and then sucked in and compressed by the compressor, and the gaseous refrigerant absorbs heat through the condenser, condenses into a liquid, and becomes a low-temperature and low-pressure refrigerant into the evaporator after throttling through the thermodynamic expansion valve, so as to complete the refrigerant cycle process.

2. Thermostatic expansion valve: The thermostatic expansion valve is not only the flow control valve in the chiller cooling system, but also the throttle valve in the refrigeration equipment, which is installed between the filter drier and the evaporator in the refrigeration equipment, and his temperature sensing bag is wrapped at the outlet of the evaporator. Its main function is to make the refrigerant liquid at high pressure and room temperature throttle and depressurize when flowing through the thermodynamic expansion valve, and turn into low temperature and low pressure refrigerant wet steam into the evaporator, and gasify and absorb heat in the evaporator, so as to achieve the purpose of refrigeration and cooling.

3. Water circulation system: the water pump is responsible for pumping the water from the water tank to the equipment that the user needs to cool, and the temperature rises after the chilled water takes away the heat, and then returns to the chilled water tank.

The chiller uses electricity as the power source, the freon refrigerant evaporates in the evaporator to absorb the heat of the refrigerant water for refrigeration, and the freon wet steam after evaporation and heat absorption is compressed into a high-temperature and high-pressure gas by the compressor, which becomes a liquid after condensation by the water-cooled condenser, and throttles into the evaporator for recirculation through the expansion valve. So as to produce 7 -12 chilled water for air conditioning at the end of the air conditioner.

Take a single-screw refrigeration compressor as an example:

Compression is generated by the meshing of an active rotor and two starwheels. Its three continuous processes of suction, compression and exhaust are achieved by periodic volume changes when the rotor and starwheel rotate.

The number of rotor teeth is six, and the star wheel is eleven.

The main components are a rotor, two starwheels, a body, a main bearing, and an energy regulating device.

The capacity can be adjusted from 10% to 100% steplessly and in three or four stages.

Compression principle: Suction process: The gas enters the rotor cogging through the suction port. With the rotation of the rotor, the starwheel enters the state of meshing with the rotor cogging in turn, and the gas enters the confined space formed by the sub-cogging surface, the inner cavity of the casing and the starwheel tooth surface).

Compression process: As the rotor rotates, the volume of the compression chamber decreases, and the gas is compressed until the front of the compression chamber is transferred to the exhaust port.

Exhaust process: After the front of the compression chamber is turned to the exhaust port, the exhaust starts to complete a working cycle. Due to the symmetrical arrangement of the starwheels, the cycle compresses twice for each rotation, and the exhaust volume is correspondingly twice as high as the exhaust volume of the previous week.

The above is the schematic diagram of an air-cooled industrial chiller.

The above is the schematic diagram of the water-cooled industrial chiller for reference!

The industrial chiller is mainly composed of compressor, refrigerant, condenser, evaporator, throttle valve, water pump, water tank, and temperature control unit. Its working principle: 1) Refrigerant working circuit:

After the refrigerant is exchanged with water through the evaporator, it is vaporized into steam; The compressor compresses the vapor into high-temperature and high-pressure steam; It enters the condenser and is cooled with cooling water or air and condensed into a high-pressure liquid; After the throttle valve is depressurized, it becomes vaporized into the evaporator again, absorbs the heat of water, and has the effect of cooling and cooling. 2) Chilled water working circuit: the water pump pumps the water in the water tank, and enters the user side after the evaporator and refrigerant heat exchange and cooling, and the user end discharges the water and then returns to the water tank, and the cycle is reciprocated.

3) Temperature control: The water tank is equipped with a temperature sensor to monitor the temperature of the chilled water in real time, and the temperature control unit controls the start and stop of the compressor to achieve constant temperature control. Typically, chillers have a temperature control accuracy of 1.

How to use ultraviolet laser chiller: (take the CS-RMC-4U01 series of Kuling era as an example).

1. Open the lid of the water tank of the UV laser chiller and add water to the water tank. When adding water, it needs to be added above the lowest liquid level. Also, during the process of adding water, be careful to add it slowly to prevent a large amount of spillage.

2. Connect the pipe, and check the tightness of the interface to confirm that it has been connected.

3. Plug in the power supply to ensure that the working voltage of the ultraviolet laser chiller in the Kuling era is stable, the power supply frequency is matched, and the rated voltage of the machine is 220-240V, and the frequency is 50Hz.

4. After the ultraviolet laser chiller is powered on, the display screen is bright, and we can set the temperature through the touch screen.

1) Press and hold the "ON off" button for 2 seconds to complete a power switch.

2) Press and hold the "set" button for 2 seconds to enter the setting interface, at this time, the set temperature area on the display screen will display "set f0", and then each time you click the "set" button, the area will display "set" in a loop

F0, Set F1, and Set F2. "set f0" indicates that the target temperature can be set at this time; "set f1" indicates that the high temperature alarm value can be set at this time; “set f2”

It means that the low temperature alarm value can be set at this time. In "set f0", "set f1", "set

F2", press and hold for 2 seconds to return the display to its normal display state. If you stay on the settings screen for more than 10 seconds without any button operation, the display will also return to its normal display state.

3) The "up" button is valid when setting the interface. In the "set

F0" interface, click this button, set the temperature to increase, press and hold for more than 2 seconds, the set temperature continues to increase, the maximum value is 35; In the "set

F1" interface, click this button, the high temperature alarm temperature difference value increases, press and hold for more than 2 seconds, the high temperature alarm temperature difference value increases continuously, the maximum value is 10. In the "set

F2" interface, click this button, the low temperature alarm temperature difference value increases, press and hold for more than 2 seconds, the low temperature alarm temperature difference value increases continuously, and the maximum value is 10.

4) The "down" button is valid when setting the interface. In the "set

F0" interface, click this button, set the temperature to decrease, press and hold for more than 2 seconds, the set temperature decreases continuously, the minimum value is 10; In the "set

F1" interface, click this button, the high temperature alarm temperature value decreases, press and hold for more than 2 seconds, the high temperature alarm temperature difference value decreases continuously, the minimum value is 0. In the "set

F2" interface, click this button, the low temperature alarm temperature difference value decreases, press and hold for more than 2 seconds, the low temperature alarm temperature value decreases continuously, the minimum value is 0.

5. After the ultraviolet laser chiller is used, it can be drained only after it is turned off. After draining, you need to first connect the lid of the water tank to the drain outlet, and confirm that the pipe has been connected, and then directly drain the water in the water tank.

General Procedure:

1 First turn the power on position.

2. Turn on the cooling switch, please note that the cooling water inlet and outlet valves must be opened; (Injection air-cooled without water tower).

3. Turn on the chilled water pump switch again, please note that the valve at the inlet and outlet of the chilled water must be opened, and the compressor will run automatically after the delay switch, please check and adjust the required temperature.

4 When powering off, please operate the shutdown in reverse order.

Chiller Matters that should be paid attention to when operating an industrial chiller.

1. The chilled water pump should not run without water in the water tank;

2. Please do your best to avoid continuous switching of the operation switch;

3. When the temperature of the frozen water reaches the set temperature, the compressor will automatically stop running, which is a normal phenomenon;

4. The temperature switch should be avoided below 5 to prevent the evaporator from freezing; (Except for cryogenic freezers).

5 To ensure that the chiller is cooled and kept in the best condition, clean the condenser, evaporator and water filter regularly.
