  Central air conditioning can be classified into three main types: electric refrigeration air conditioning, lithium bromide refrigeration air conditioning, and other energy source air conditioning. Among them, electric refrigeration air conditioning is the most commonly used form of air conditioning. Let's discuss the classification of electric refrigeration air conditioning in detail. I. Classification by Cooling Method Air-cooled: The condenser uses forced air convection for heat exchange. This type is commonly used in residential air conditioners. Air-cooled air conditioners can be categorized into single cooling type and heat pump type. The single cooling type is only used for cooling in summer, while the heat pump type can provide both cooling in summer and heating in winter. Water-cooled: Heat dissipated by the condenser is cooled using water flow. In order to save water, the cooling water discharged from the condenser is pumped to the cooling water tower, where it undergoes...

  More dust and poor water quality in  the chiller environment will affect the normal operation of the equipment, and even lead to downtime. In order to increase the operating power of the chiller, it is necessary to create high-quality conditions for use and effectively maintain the operating power of the  air-cooled chiller . ​ When using the chiller, if there is a lot of dust and other problems in the environment during the operation of the equipment, the normal operation of the equipment will be affected after the equipment enters the water-cooled chiller. In order to prevent the chiller equipment from being affected by dust in the environment and a large amount of scale due to long-term lack of maintenance, companies need to conduct professional inspections on chillers on a regular basis. A layer of solid or ooze builds up, called fouling, which adds additional fouling thermal and flow resistance, increasing required heat transfer area, power consumption and maintena...

  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 chille...
