  In  flooded chiller systems , it’s common for the condenser to have a higher heat transfer capacity than the evaporator. This difference stems from the physical characteristics of the refrigeration cycle. The condenser is essential for transforming refrigerant from a gas to a liquid state, releasing both the heat absorbed by the evaporator and the additional heat generated during the compression process. Key Reasons Behind Higher Condenser Heat Transfer 1. Handling Additional Heat from Compression After the refrigerant absorbs heat from its surroundings in the evaporator, it flows into the compressor, where it's compressed into a high-temperature, high-pressure gas. This compression step adds extra heat to the refrigerant, which the condenser must release. Therefore, the condenser not only dissipates the heat absorbed by the evaporator but also manages the additional heat from compression, resulting in a higher heat transfer demand. 2. Enhanced Heat Transfer Area and Design ...

  In the food processing industry, the choice of equipment material directly impacts the safety of products and the hygiene standards of production processes.   Stainless steel heat exchangers , known for their excellent corrosion resistance, easy-to-clean surfaces, and sanitary properties, have become indispensable in food factories. But is it really necessary for food factories to use all-stainless steel heat exchangers? Why Stainless Steel Heat Exchangers Are Essential in Food Processing 1. Ensuring Food Safety: Food safety is paramount in food processing. Stainless steel heat exchangers have smooth surfaces that resist the buildup of bacteria and contaminants, effectively preventing food contamination. Their corrosion-resistant nature ensures that they do not react with acidic or alkaline substances, preserving the quality of the food. Additionally, stainless steel’s high-temperature resistance allows the heat exchanger to endure high-temperature sterilization processes, e...

  High-temperature heat pump units   have become essential to modern energy utilization technologies, finding widespread applications across various industries such as industrial, agricultural, and commercial sectors. These units' unique performance and advantages are key in driving energy transitions and achieving energy conservation and emission reductions. This blog will explore the working principles, application areas, technical features, and future trends of high-temperature heat pump units. How Do High-Temperature Heat Pump Units Work? High-temperature heat pump units operate based on the principle of the reverse Carnot cycle. They use a small amount of electrical or thermal energy to absorb heat from a low-temperature source and transfer it to a high-temperature source. The process involves four key stages: evaporation, compression, condensation, and expansion. During evaporation, the refrigerant absorbs heat from the low-temperature source and turns into a low-pressur...
