Using the scroll compressor chiller as a foundation, other types of chillers can be created, such as the following:
Scroll Water Chiller:
The water-cooled scroll chiller uses the compressor to cool the water. Then, it transfers the water's cooling effect to heat. The condensation process happens through a refrigerant cycle. The condensate can absorb heat from the water. Thus, the scroll water chiller is produced. The machine is suitable for central air conditioning systems. And it is often applied to large commercial buildings and industrial factories.
Scroll Air Chiller:
The working principle of the air-cooled scroll chiller is the same as that of the water-cooled scroll chiller. The only difference lies in the cooling medium and heat exchange method. An air chiller typically uses an evaporator exchanged with ambient air. It is a popular choice of cooling solutions for companies, factories, and laboratories that need to reduce the temperature of certain areas or equipment.
Photovoltaic Scroll Compressor Chiller:
The scroll photovoltaic chiller is a cooling device powered by photovoltaic cells. A photovoltaic cell is a semiconductor device that converts solar energy directly into electric energy. The refrigeration process of these chillers are similar to traditional scroll compressors. However, their driving power source is change from grid electricity to solar electricity. This change makes them fit for use in areas lacking a stable power supply or where solar energy can be utilized. Scroll photovoltaic compressors offer independent and sustainable cooling solutions powered by solar energy in such places.
Cooling Capacity:
Typically, it is expressed in kilowatts (kW) or tons. It should be ensured that the scroll chiller's cooling capacity can meet the requirements of the specific application or environment.
Power Consumption:
It should be ensured that the power consumption of the scroll chiller is in line with the budget and energy management goals, thus reducing operating costs.
Operating Temperature Range:
The refrigerant temperature range of the scroll chiller should be suitable for the specific application to ensure optimal performance and efficiency.
Refrigerant Type:
It should be ensured that the type of refrigerant used complies with environmental and regulatory requirements to avoid potential environmental risks.
Compressor Type:
It should be ensured that the choice can meet the specific application requirements, such as variable frequency compression for applications that need to adjust the refrigerating capacity dynamically.
Control System:
It should be ensured that the control system can realize the automatic control and monitoring of the scroll chiller and possesses functions such as remote monitoring and data logging.
Dimensions and Weight:
It should be ensured that the size and weight of the scroll chiller are suitable for installation and space constraints to facilitate system integration and installation.
It is important to remember that the scroll chiller needs to be properly maintained by a specialized technician to ensure its reliable operation, energy efficiency, and longevity. The following are some common maintenance tasks:
Regular inspection:
Regularly check the appearance and parts of the scroll chiller, ensuring that there are no deformation, looseness, leakage, etc. of the refrigerant pipes, electrical components, and other parts, to avoid potential safety hazards.
Comprehensive maintenance services:
For key parts of the scroll chiller. For example, cleaning the condenser, evaporator, and other heat exchangers, thus ensuring proper heat exchange efficiency.
Replacement of vulnerable parts:
For example, cleaning or replacing the filter of the scroll chiller, which ensures keeping the refrigerating system clean and preventing clogging and pollution.
Lubrication maintenance:
Regularly check the oil level and oil quality of the compressor's lubricating oil, and replenish or replace it as required to ensure proper lubrication and operation of the bearings and sealing system.
Electrical system maintenance:
Cleaning and maintenance of the electrical system of the scroll chiller, for instance, check for loose or damaged connections, check whether the circuit is working properly to ensure electrical safety and reliable operation.
Routine Maintenance Record:
Operating parameters and maintenance records, etc., in order to track the performance and maintenance history of the scroll chiller, thus facilitating future maintenance and troubleshooting.
Industrial cooling:
Scroll chillers are widely used in the manufacturing industry for process cooling. They can provide precise temperature control to help increase productivity, reduce product defects, and improve overall process efficiency. Some applications include machining centers, plastic injection molding machines, rubber vulcanization boxes, electronic baking ovens, chemical reaction tanks, etc.
Food and beverage processing:
Food and beverage processing requires strict temperature control to preserve product quality, but some may need rapid freezing. Scroll chillers can provide the refrigeration needed to meet these requirements. They can be used in areas like meat and dairy processing, beverage production, cold chain logistics, and food freezing and refrigeration.
Cold storage and refrigeration:
Centrifugal chillers are the backbone of cold storage and refrigeration systems. Whether it's a walk-in refrigerator, blast freezer, or cold storage warehouse, they can provide the refrigeration required for proper temperature control and preservation.
HVAC systems:
Scroll chillers play a central role in a wide variety of HVAC systems. Whether it's central air conditioning, commercial refrigeration, or district heating and cooling, they can provide the temperature control and comfort required.
Medical and pharmaceutical applications:
Medical and pharmaceutical applications require strict temperature control to preserve product quality and protect equipment. Scroll compressors can provide the refrigeration required to meet these requirements. Some use areas include hospitals, laboratories, clean rooms, pharmacies, etc.
Wholesale scroll compressor chillers can be chosen based on the needs of the target market.
Determining Airflow and Temperature
Find out the optimal temperature for processes and the transmission of chilled air. Doing a process analysis will help determine what temperature the refrigerant needs to achieve. Also, find out how much chilled air is needed to carry/transfer heat. The amount of airflow needed may be in CFM (cubic feet per minute) or some other unit. The optimal temperature and airflow needed will determine the scroll compressor chiller's capacity and operating parameters.
Considering System Design
Whether the scroll compressor chiller will be used in an air conditioning system or for process cooling will affect the type of system design it will be a part of. Some systems may have multiple chillers working together, while others may use a different method of heat transfer and removal. Understanding the overall system will help in choosing the right scroll compressor chiller that will work well with the rest of the components.
Evaluating Energy Efficiency
Factors like part load performance, integrated part load performance, full load performance, heat recovery potential, and auxiliary load must be considered. Ideally, a scroll compressor chiller with a high energy efficiency ratio (EER) or coefficient of performance (COP) should be chosen. If possible, choose models with variable speed drives that can adjust their power output according to the specific cooling needs.
Considering Physical Characteristics
Some applications may need to have a compact or light-weight scroll compressor chiller due to space constraints or weight limitations. Durability may also be a concern for some customers, especially if the machine will be used in a remote location where regular maintenance is not possible. Wholesalers should consider whether a durable machine with a robust build will better meet the customer's needs.
