  Industrial chillers  include air-cooled chillers, water-cooled chillers, and  screw chillers , which are widely used in the plastic industry, pharmaceutical industry, food processing industry, chicken hatching bases, etc. However, many customers do not know how to use the industrial chiller after purchasing it, and do not know whether the machine is working properly. Let's talk about the main signs of normal operation of the chiller. 1. Condenser: Water-cooled chiller cooling water system: The cooling water should be sufficient, the water pressure should reach more than 0.15MPa, and the temperature difference between the inlet and outlet water should not be too large, otherwise it indicates insufficient water flow. 2. Compressor: When the compressor is running, the optimal superheat is 4~8 degrees, the maximum suction superheat does not exceed 15℃, and the condensation phenomenon is limited to the compressor return air pipe, and there should be no frost in other parts. ...

  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...

  In the world of industrial equipment, pairing   low-temperature chillers   with pump skid units has become a recommendation many companies swear by. At H.Stars, we highly recommend this combination for several strategic reasons, which reflect our expertise and forward-thinking approach to industrial operations. ​ The Benefits of Using Pump Skid Units with Low-Temperature Chillers When it comes to industrial cooling systems, maintaining a stable and efficient water circulation system is critical for ensuring the consistent output of the chiller. Pump skid units, thanks to their integrated design, provide a highly effective solution to this challenge. Here’s why they make a perfect match for low-temperature chillers: 1. Optimized System Efficiency Pump skid units play a crucial role in stabilizing water flow parameters—speed, pressure, and volume—ensuring the chiller operates at peak efficiency. By maintaining steady water circulation, they prevent fluctuations in cooling...

  As global environmental concerns continue to rise, the refrigeration industry is undergoing a significant transformation. Water-cooled low-temperature units exported overseas are now increasingly adopting the eco-friendly refrigerant R404A, leading the way in the industry's green development. Here's a deeper look into this trend. Why Is R404A Becoming the Preferred Refrigerant for  Water-Cooled Low-Temperature Units ? R404A is a blend of refrigerants that stands out due to its environmentally friendly properties. It is free from Ozone Depleting Potential (ODP) and has a relatively low Global Warming Potential (GWP), making it an ideal substitute for traditional refrigerants. This balance between high-performance cooling and environmental friendliness has made R404A especially popular in regions with strict environmental regulations, such as Europe and North America. Water-cooled low-temperature units exported to these areas are now commonly equipped with R404A to meet local ...

  In the HVAC and refrigeration industry,   magnetic levitation flooded-type heat exchanger units  are emerging as a promising solution. One of the most important aspects of these units is their Coefficient of Performance (COP), a key indicator of energy efficiency. What Makes COP So Important? COP is a critical metric for measuring the energy utilization efficiency of heat exchange units. The higher the COP, the more effective the system is at converting electrical energy into cooling or heating output. In ideal operating conditions, magnetic levitation flooded type heat exchanger units can achieve COP values as high as 6 or even more. How Does Magnetic Levitation Technology Enhance COP? Magnetic levitation technology plays a pivotal role in achieving such high COP values. Unlike traditional compressors, magnetic levitation compressors operate without mechanical friction, significantly reducing energy losses. The flooded type evaporator further boosts heat exchange effic...

  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...

  Many businesses in the industrial refrigeration sector are concerned about efficient space utilization.  H.Stars  has introduced a  boxed industrial chiller  th at offers a new solution for space-saving in industrial cooling applications. Traditional industrial chillers tend to be bulky and occupy significant floor space within facilities. In contrast, H.Stars' boxed chillers feature clever design and engineering innovations that maximize space efficiency. By integrating numerous components into a compact boxed structure, these units can save up to 20% of the space compared to standard models. Importantly, this space-saving design does not compromise cooling performance. The boxed chillers employ advanced refrigeration technology, ensuring stable and efficient cooling for industrial equipment, even in limited spaces. This makes them an ideal choice for factories, workshops, and laboratories that require effective cooling but face spatial constraints. Additiona...
