The air-cooled screw chiller (heat pump) unit is a highly efficient and energy-saving central air-conditioning system that integrates cooling and heating functions. It occupies an important position in the HVAC market with its unique design and performance. It is suitable for a variety of occasions.
Working Principle：
The air-cooled screw chiller (heat pump) unit utilizes the heat from the air to provide heating and cooling regulation for buildings. In the cooling mode, the unit absorbs the heat from the interior and releases it to the outdoor air through the refrigeration cycle. In the heating mode, the process is reversed, drawing heat from the outdoor air to warm the indoor air.
Core component 1: Screw compressor
The screw compressor is the core component of the refrigeration system, which compresses the refrigerant vapor through its rotational movement, thereby increasing its temperature and pressure, and is crucial for heat transfer. Ruidong Group's air-cooled screw units use well-known brand compressors such as Hanbell and Bitzer, ensuring the high performance and stability of the equipment. At the same time, it provides customized services to meet the personalized needs of customers.
Core component 2: Shell and tube heat exchangers
In the refrigeration process, the shell and tube heat exchanger acts as a condenser, cooling the high-temperature, high-pressure gas discharged from the compressor into a liquid state; in the heating process, it serves as an evaporator, absorbing heat from the air. The shell and tube heat exchangers used by Ruidong Group are integrated with their own brand and quality assurance, strictly controlling the product quality, deeply understanding the usage requirements, flexibly meeting the design requirements, and achieving personalized customization services.
Core component 3: Electronic Control System
The system employs an advanced electronic control system from Siemens, enabling intelligent control and optimized operation of the unit, ensuring the system runs efficiently and stably. Electrical components are selected from the French Schneider brand, extending the service life of the unit and reducing the maintenance costs for the clients.
Core component 4: High-Efficiency Fans
Designed to optimize air flow, enhance heat exchange efficiency, while reducing noise and energy consumption.
The air-cooled screw chiller heat pump unit has multiple advantages, making it an ideal choice for many commercial and industrial applications.
High Energy Efficiency Ratio (EER): The air-cooled screw chiller (heat pump) unit adopts a high-efficiency screw compressor, which consumes less energy while providing the same cooling or heating capacity.
Intelligent Control: The unit is equipped with an intelligent control system that can automatically adjust the operating state according to the actual load demand, thereby reducing energy waste. At the same time, Ruidong’s unit has an RS485 interface, which can achieve remote control and improve management efficiency.
Multiple Anti-Freeze Technologies: In the winter heating mode, Ruidong’s unit utilizes multiple intelligent anti-freeze functions to effectively prevent the increase in energy consumption and equipment damage caused by low temperatures, ensuring the stable operation of the system.
Electronic Expansion Valve Control: Utilizing electronic expansion valve control technology, the precision of our electronic expansion valve adjustments can reach up to 2600 steps, allowing for accurate control of the refrigerant flow, thereby further enhancing the energy-saving effect.It is especially capable of meeting the precise temperature control requirements in various industrial production processes, ensuring production efficiency and product quality.
High-Efficiency Heat Exchanger Design: The shell and tube heat exchanger produced by Ruidong Group features high-efficiency internal thread copper tubes, which increase the heat transfer area and reduce energy loss.
Use of Eco-friendly Refrigerants: The use of environmentally friendly refrigerants such as R407C and R134a, which have an ozone depletion potential (ODP) of 0, complies with current environmental protection requirements.
Low Noise Design: By optimizing the design of fan blades and using high-efficiency, low-noise fans, the noise during the operation of the unit is reduced, minimizing noise pollution to the surrounding environment.
Intelligent Defrosting Technology: The adoption of intelligent defrosting technology reduces heat loss in heating mode, avoiding energy waste and environmental impact caused by frequent defrosting.
Wide Application Range: The air-cooled screw chiller can operate stably in ambient temperatures ranging from -35°C to 50°C, suitable for various climatic conditions.
Environmental Adaptability: Industrial areas may face the problem of water resource scarcity. The air-cooled screw chiller does not require cooling towers, saving water resources and demonstrating strong adaptability.
Space Utilization: As there is no need for cooling towers or machine rooms, the air-cooled screw chiller can be directly installed outdoors, saving valuable building space, especially suitable for commercial areas with limited space.
Easy Maintenance: The simple structure and convenient maintenance reduce maintenance costs and time, meeting the high operational efficiency requirements of commercial buildings.
Air-cooled screw chiller（heat pump）unit, with their high efficiency and eco-friendly features, are an ideal choice for modern buildings as a reliable source of cooling and heating. They ensure a comfortable indoor environment suitable for commercial spaces like shopping malls, offices, and hotels, as well as industrial applications requiring process cooling or heating in sectors such as electronics, pharmaceuticals, and food processing.
In practical applications, the selection and design of air-cooled screw chillers should be tailored to specific needs, environmental conditions, and targeted energy efficiency to ensure optimal performance and economic benefits.
