Domestic screw chiller (low temperature)

The refrigeration cycle of domestically produced screw chillers (low temperature) mainly includes four processes: the gaseous refrigerant from the evaporator is adiabatically compressed into high-temperature and high-pressure gas by the compressor, cooled and condensed into a liquid state under constant pressure in the condenser, expanded to low pressure through the throttle valve to become a gas-liquid mixture, and the low-temperature and low-pressure liquid refrigerant absorbs the heat of the cooled substance in the evaporator to become a gaseous state, entering the compressor again to start a new cycle.

1、 Core features of the product

1. Core components ensure efficient and stable operation

　　Domestic screw chiller (low temperature)Equipped with a semi enclosed twin-screw compressor, this design utilizes excellent screw tooth technology and precision manufacturing processes to achieve efficient compression through rotor meshing. Compared to traditional compressors, its energy efficiency can be improved by up to 20% -30%. Not only does it have outstanding refrigeration and heating efficiency, but the noise generated during operation is also much lower than industry standards, creating a quiet usage environment for users. At the same time, the compressor operates with minimal vibration, coupled with optimized base damping design, ensuring long-term stable operation of the unit and reducing component losses caused by vibration.

In terms of key component selection, it is equipped with high-quality bearings and has undergone rigorous durability testing, with a service life of at least 40000 hours. Even under high-intensity and long-term operating conditions, stable performance can still be maintained, significantly reducing maintenance frequency and costs. In addition, the built-in oil separator adopts an efficient separation structure. Compared with traditional external separators, the volume is reduced by about 30%, but the separation efficiency is significantly improved. It can effectively separate lubricating oil from refrigerant, ensure the efficient operation of the refrigeration system, and extend the service life of the compressor.

2. Intelligent energy regulation to achieve energy conservation

The unit supports multi-level energy control, which can achieve staged or infinite energy regulation within a wide range of 0% -100%. When the external environmental temperature changes or the user side load decreases, the unit can automatically adjust the operating status and cooling output of the compressor. For example, during nighttime or low load periods, the unit can reduce its operating power to 30% or even lower, accurately matching actual needs. Compared to equipment operating at fixed power, it can save 30% -50% of electricity consumption, effectively reducing users' long-term operating costs.

3. Innovative heat exchange design to enhance refrigeration efficiency

As the core component of the refrigeration system, the evaporator is used in domestic screw chillers, which adopt high-efficiency shell and tube heat exchangers and are equipped with built-in high-efficiency heat exchange toothed tubes. This special design significantly increases the heat transfer area, coupled with optimized fluid channel layout, making the heat exchange between refrigerant and refrigerant (such as water or ethylene glycol solution) more complete, and improving the heat transfer efficiency by about 20%. In addition, users can also choose stainless steel plate heat exchangers according to their actual needs, which have the characteristics of small size, higher heat transfer efficiency, and convenient cleaning and maintenance, especially suitable for applications with poor water quality or strict space requirements.

4. Intelligent control system, convenient operation and management

　　Domestic screw chiller (low temperature)Equipped with a powerful control system, covering multiple functions such as startup control program, energy regulation program, shutdown control program, fault diagnosis, etc. The system has intelligent fault diagnosis capability. Once an abnormality is detected (such as high pressure, abnormal temperature, current overload, etc.), the fault point can be quickly located within 3 seconds, and displayed on the controller interface through code or text prompts. At the same time, an alarm is triggered to help maintenance personnel quickly troubleshoot the problem. In addition, the system also supports functions such as running time statistics, historical data queries, and real-time display of operating status, making it convenient for users to comprehensively grasp the operation status of the unit.

On the operating interface, equipped with a high-definition computer LCD touch screen controller, adopting a graphical interactive design, the interface is simple and intuitive. Users can easily complete parameter settings, mode switching, status monitoring and other operations through the touch screen, without the need for complex training to get started. At the same time, the unit does not need to be equipped with cooling towers and related cooling water circulation systems, greatly simplifying the installation process, reducing the footprint and initial investment costs.

2、 Diversified application areas

1. Electronic factory: Guardian of precision environment

The manufacturing of electronic components and chips has almost strict requirements for environmental temperature and humidity, and even small fluctuations in temperature and humidity can affect product yield. With precise temperature control of ± 0.5 ℃ and humidity adjustment capability of ± 5%, it creates a stable production environment for places such as dust-free workshops and semiconductor production lines, effectively avoiding product defects caused by abnormal temperature and humidity, and ensuring the high-precision requirements of electronic manufacturing.

2. Food processing plant: Quality preservation expert

It plays a crucial role in food processing and storage. In the meat processing workshop, the ambient temperature can be stably controlled below 10 ℃ to inhibit microbial growth; In the cold storage, precise temperature control ranging from -30 ℃ to 5 ℃ is provided according to different food storage needs. Whether it is the preservation of fresh fruits and vegetables or the freezing of frozen foods, it can ensure the quality and safety of food and extend the shelf life.

3. Pharmaceutical factories: strictly adhere to the lifeline of drug quality

Drug production follows strict GMP standards, providing a clean environment with constant temperature and humidity for pharmaceutical workshops, raw material warehouses, and finished product warehouses. In the vaccine storage process, the temperature can be precisely controlled between 2 ℃ and 8 ℃ to ensure the activity of biological products; In the solid preparation workshop, stable temperature and humidity can prevent drugs from getting damp and deteriorating, providing reliable assurance for drug quality.

4. Data center: the backing for stable operation of equipment

The servers in the data center operate continuously 24 hours a day, generating a large amount of heat, which requires certain stability and cooling efficiency of the refrigeration system. With its fast response cooling capacity and precise temperature control, it can maintain the temperature of the data center at 22 ℃± 1 ℃, effectively preventing server overheating and downtime. At the same time, its intelligent energy-saving features can also reduce the energy consumption cost of data centers and help build green data centers.
