Secondly:Ethylene glycol low-temperature freezerIntroduction

1.A low-temperature freezer is a refrigeration equipment consisting of three main components: a refrigeration system, a water system, and an electrical system. The core of the freezer is the refrigeration system, which is composed of a compressor, evaporator, condenser, and expansion valve. The air-cooled box type chiller is a chiller that uses a finned condenser (radiator) to dissipate heat from the environment through one or more external rotor fans.

2.Core advantages of air-cooled system: It comes with a built-in refrigeration system, water pump, water tank, and control system. Customers can install it themselves upon arrival at the customer's site and use it in areas with scarce water sources and inconvenient cooling water sources.

3： Application Fields

With the development of modern science and technology and the diversified requirements of products, some processes and equipment cannot meet the requirements of room temperature water, such as pharmaceutical and chemical industries, food and beverage industries, and the production of special electronic materials. These high end industries often require low-temperature freezers to meet the process requirements. The Dawosi low-temperature freezer adopts foreign compressors and excellent process structure design. To meet some low temperature requirements-40Freezing requirements within the specified temperature range.

Design of refrigeration unit

1.The refrigeration unit is an integral structure with a built-in water tank and water pump. Users only need to connect the pipeline and power supply.

2.feature

Davosi-The air-cooled chiller unit adopts an international vortex compressor, matched with high-quality and high-efficiency fins to make the condenser, evaporator, and world control components, making the unit have the advantages of small size, low noise, high energy, long service life, and easy operation. Its beautiful and exquisite appearance design and reliable high-efficiency quality are among similar products!

：

Imported brand vortex compressor,High energy efficiency ratio,Reliable operation,Long lifespan;

Adopting a dedicated temperature controller for chiller units, it has high temperature control accuracy and stable performance.,Fully digital Han display,Through communication with external devices, remote users, and control roomsRS485Interface connection.Can achieve the following multiple control functions(optional)：

Multiple protection functions:Temperature protection for compressor exhaust overheating, motor overheating, cold water antifreeze, etc.: electrical protection for overcurrent, phase loss, and reverse phase; High and low pressure, oil level, water cut-off and other emergency state protection of refrigerant system

Necessary maintenance and management functions such as alarm, prompt, recording, and retrieval can be set for the above protection functions (optional)

Automatically achieve unmanned operation management according to the predetermined work plan through remote communication

Select international control components such as thermal expansion valves, solenoid valves, and one-way valves to ensure efficient and reliable operation of the unit over a wide range of operating conditions

Oil separator: By using a separator, the refrigeration oil in the exhaust is further separated, which improves the reliability and heat transfer efficiency of the equipment and enhances efficiency

3.Host structure:

Air-cooled condenser

The washable air-cooled condenser adopts reinforced heat exchange tubes, and the design of the subcooling section increases the heat dissipation area. The fluorine side design pressure is30 barEnsure the safety of the equipment.

evaporator

Adopting a dry water tank coil evaporator/Shell and tube evaporator/Plate evaporators are selected according to different types, and the design pressure on the water side is10 barThe design pressure on the fluorine side is25 barEvaporator outer packaging50mmThe thick soft closed cell rubber sponge insulation material effectively prevents heat transfer between the evaporator and the outside air of the machine room, reducing energy loss.

electric control system

The main components are all imported brand components to ensure the reliability of the unit operation. The unit control adopts a dedicated temperature control for the chiller, making the operation more convenient.

water pump-Structure: The product adopts an integrated structure of motor and pump body. The motor is a fully enclosed, air-cooled standard motor, and its dimensions comply with national design standards. The product pump body is equivalent to a section of pipeline, which is used during pump maintenance. The connection between the motor of the product pump head and the device of the pump, and the sealing element between it and the pump body adoptsOThe circular design solves the problem of system leakage. If the pumped liquid is non corrosive, non-standard customization is possible.
