chiller 5 kw – Precision Chiller

 

The 5 kw chiller adopts non-start-stop refrigeration technology, combined with PID temperature control, fast cooling, and is a high-precision and high-stability cooling equipment. It provides options such as temperature, pressure, flow rate, conductivity, etc.; standard stainless steel interface, can be equipped with various specifications of joints and hoses; models with different cooling capacity, used in various laboratories and industrial production fields, to meet different requirements Cooling constant temperature requirements. What is the composition and structure of a 5 kw chiller?

1. Compressor: The compressor is the core component of the entire refrigeration system and the source of power for refrigerant compression. Its function is to convert the input electrical energy into mechanical energy and compress the refrigerant.

2. Condenser: In the refrigeration process, the condenser plays the role of outputting heat energy and condensing the refrigerant. After the high-pressure superheated steam discharged from the refrigeration compressor enters the condenser, it transfers all the heat absorbed in the working process, including the heat absorbed from the evaporator and refrigeration compressor and in the pipeline, to the surrounding medium (water or Air) is taken away; the high-pressure superheated vapor of the refrigerant recondenses into a liquid. (According to different cooling media and cooling methods, condensers can be divided into three types: water-cooled condensers, air-cooled condensers, and evaporative condensers.) Liquid receiver: The liquid receiver is installed after the condenser, and it is connected with the condenser The discharge pipe of the device is directly connected. The refrigerant liquid in the condenser should flow into the liquid receiver unimpeded, so that the cooling area of the condenser can be fully utilized. On the other hand, when the heat load of the evaporator changes, the demand for refrigerant liquid also changes accordingly, and at that time, the liquid receiver plays the role of adjusting and storing the refrigerant. For small-scale refrigeration systems, liquid receivers are often not installed, but condensers are used to adjust and store refrigerants.

3. Dry filter: In the refrigeration cycle, moisture and dirt (oil, iron filings, copper filings) must be prevented from entering. The source of moisture is mainly the trace moisture contained in the newly added refrigerant and lubricating oil, or due to Moisture from air ingress during system servicing. If the moisture in the system is not removed, when the refrigerant passes through the throttling valve (thermal expansion valve or capillary tube), the moisture will sometimes freeze into ice due to the drop in pressure and temperature, blocking the passage and affecting the normal operation of the refrigeration device. Therefore, a dry filter must be installed in the refrigeration system.

4. Thermal expansion valve: The thermal expansion valve is not only a flow regulating valve in the refrigeration system, but also a throttle valve in the refrigeration equipment. It is installed between the dry filter and the evaporator in the refrigeration equipment. Its temperature sensing package It is wrapped around the outlet of the evaporator. Its main function is to make the high-pressure and normal-temperature refrigerant liquid throttling and reducing pressure when it flows through the thermal expansion valve, turning into low-temperature and low-pressure refrigerant wet vapor (mostly liquid, a small part is steam) into the evaporator and vaporized in the evaporator absorb heat, and achieve the purpose of cooling and cooling.

5. Evaporator: The evaporator is a heat exchange device that relies on the evaporation (actually boiling) of the refrigerant liquid to absorb the heat of the cooled medium. Its function in the refrigeration system is to absorb heat (or output cooling). In order to ensure that the evaporation process can be carried out stably and permanently, the evaporated gas must be continuously pumped away by a refrigeration compressor to maintain a certain evaporation pressure.

6. Refrigerant: Most of the 5 kw chillers used in modern industry use R22 or R12 as the refrigerant. Due to the gradual prohibition of Freon refrigerants, energy-saving and environmentally friendly R410A and pure natural hydrocarbon refrigerants will be gradually adopted . Refrigeration is the flowing working medium in the refrigerant refrigeration system. Its main function is to carry heat and realize heat absorption and heat release when the state changes.

7. Water circulation system: The water circulation system is a water pump that sends water from the water tank to the equipment that the user needs to cool. After the chilled water takes away the heat, the temperature rises, and then returns to the chilled water tank.

8. Electrical automatic control system: The electrical automatic control system includes a power supply part and an automatic control part. The power supply part supplies power to compressors, fans, water pumps, etc. through contactors. The automatic control part includes thermostat, pressure protection, delayer, relay, overload protection, etc., which are combined to achieve automatic start and stop according to water temperature, protection and other functions.
