Compressor Selection of Intelligent Manufacturing | Hstarschiller.com

 From the perspective of design to talk about the special "intelligent" creation of H.Stars Group,which is related to compressor type selection.

According to the conventional thinking, the choice of compressor type is not much difficult , small unit with scroll compressor, medium unit with screw compressor, large unit with centrifugal compressor.


Why mention the compressor type choice again?
Let's do a simulation selection. Suppose we need a 300KW water-cooled chiller
Screw Type，40STD-280WS4，Cooling Capacity:284kW，Price is 15200USD

Scroll Type，20STB-100WFO4，Cooling Capacity:300kW，Price is 13500USD


From the data, the cooling capacity of the scroll type chiller is 6% larger than the screw type chiller, and the price of the scroll type chiller is 13% lower than the screw type chiller.


We believe you have a clear idea of which product is more competitive.

It is also applied to Air cooled chiller.The following introduces the scroll type chiller and screw type chiller cooling overlap area.


scroll type chiller


According to the H.Stars Group Catalog A31 " H.Stars Modular Scroll Water cooled/ Air cooled Chiller", it can be seen that the cooling capacity of a single scroll chiller can achieve 300KW.
The minimum cooling capacity for a single screw chiller is 90KW.

It can be seen from here that the cooling capacity range of one chiller is 90KW ~ 300KW, which is the overlap area of scroll type and screw type.



screw type chiller


In the future, when the cooling capacity of one chiller is between 90KW and 300KW, it can choose a flexible scheme between the scroll and the screw, which will have a more competitive advantage in the market.

Avoid Downtime, Cut Costs: Smart Maintenance for Smarter Chillers

  Screw water-cooled chillers   typically operate around 3,000 hours per year, depending on China's climate and geographical conditions. Regular and scientific maintenance is crucial to ensure long-term, reliable operation, extend the lifespan, and reduce operating costs. Maintenance and Upkeep Preventive maintenance during operation and inspection involves creating annual and monthly maintenance plans based on actual operating conditions. Shutdown Procedures In winter, clean and dry the unit. Open the drain valve to empty the  shell-and-tube heat exchanger  to avoid freezing. The shutdown sequence is: chiller off - cooling tower fan off - cooling water pump off - chilled water pump off. Special attention to anti-freezing: 1. Drain the evaporator and condenser if the unit is outdoors below 0°C during standby. 2. Interlock the water flow switch with the unit to prevent freezing when the chilled water flow switch malfunctions. 3. Ensure water in the evaporator is flowi...

What Are the Key Requirements for Flooded-Type Heat Exchangers in Air Suspension Chillers

  Air suspension chillers   are crucial in many industrial and commercial applications, and the flooded-type heat exchanger is one of the most important components of these systems. Understanding the requirements of the heat exchanger is essential to ensuring the air suspension units operate efficiently and remain stable. A flooded-type heat exchanger works by transferring heat between two fluids with different temperatures. In air suspension chillers, it helps regulate temperature, optimize energy use, and improve overall performance. For instance, it can transfer heat from high-temperature gases to low-temperature liquids, or vice versa. 1. Material Requirements 1.1 Corrosion Resistance In many industrial environments, fluids can be corrosive. For example, they may come into contact with acidic or alkaline substances. To withstand these conditions, the heat exchanger’s tubes and casing need to be made from corrosion-resistant materials, such as stainless steel. Stainless ste...

Hotels Go Green: Heat Recovery Chillers Cut Costs and Carbon Footprints

  In the operation of hotels, energy costs are a significant factor that cannot be overlooked. The advent of   heat recovery chillers   offers an efficient and energy-saving solution for hotels. ​ A heat recovery chiller, in simple terms, not only performs cooling tasks but also effectively recovers heat. For hotels, this is a highly practical feature. Traditional chillers only accomplish cooling, wasting the heat generated. However, heat recovery chillers are different; they can convert the otherwise wasted heat into usable hot water. In principle, during the cooling cycle of a chiller, the refrigerant releases heat. Heat recovery chillers use special devices to collect this heat, and through a series of heat exchange processes, they can produce hot water. This hot water can be used in various scenarios within the hotel. For example, it can supply water for guest rooms' washing and brushing, provide hot water for the hotel's restaurant kitchen, and even be used for heati...
