  Since the   water-cooled chiller   needs the help of the cooling tower during its operation, after purchasing the water-cooled chiller, it is necessary to complete the normal operation of the water-cooled chiller according to the relevant experience introduced by the   chiller factory   to ensure the water-cooled chiller unit has high performance. How to choose to buy a cooling tower? In the actual use environment, there are different types of cooling water towers. Simply distinguished from the shape, domestic cooling water towers are divided into two types: rectangular and circular. As for specific functions, rectangular and circular cooling towers have similar functions, and there is no According to the introduction of the  water-cooled chiller supplier , the circular cooling tower can adapt to more used environments and achieve the purpose of improving the working efficiency of water-cooled chillers. Determine the model and specific specifications of t...

  The   heat pump water heater   is a high-efficiency heat energy promotion and transfer device based on the reversed Carnot cycle. It uses a small amount of electric energy as power and refrigerant as a carrier to continuously absorb low-taste heat energy in the air and convert it into Using the high-grade heat energy, the high-grade heat energy is released into the water that needs to be heated to produce domestic hot water, which is then delivered to the user through the hot water pipeline. It can transfer heat from low-temperature heat sources (such as air, soil, seawater, groundwater, etc.) to the water that needs to be heated to achieve the function of heating the water. How to choose a heat pump water heater? 1. Choose a brand. Heat pump water heaters (heaters) are generally used as durable consumer goods. When a failure occurs during use, consumers need the manufacturer to provide after-sales service to inspect, repair, or replace parts. A product manufacturer wit...

  The basic principle of refrigeration system: After the liquid refrigerant absorbs the heat of the object being cooled in the evaporator, it vaporizes into low-temperature and low-pressure vapor, is inhaled by the compressor, compressed into high-pressure and high-temperature vapor, and then discharged into the condenser, exothermic to the cooling medium (water or air) in the condenser, condenses into high-pressure liquid and then throttles down into low-pressure and low-temperature refrigerant through the throttle valve, enters into the evaporator again to absorb heat and vaporize, so as to achieve the cycle of refrigeration. purpose. In this way, the refrigerant in the system completes a refrigeration cycle through four basic processes: evaporation, compression, condensation, and throttling. The   water-cooled chiller   is mainly composed of a closed scroll compressor, condenser, evaporator, expansion valve, and electric control system. 1.Compressor The compressor is t...

  Condenser and cooler are one of the important parts of the heat exchange process, and the utilization rate is very high. But everyone does not know the difference between the condenser and the cooler in the design, and how to prevent damage to the water-cooled chiller? Today the   water-cooled chiller supplier   will talk about this aspect. There are three main differences between the condenser and the cooler in the design. The first is whether there is a phase change, the second is the difference in heat transfer coefficient, and the third is the series heat exchanger. Let's talk about these three points in turn. 1. With or without phase change The condenser will condense the gas phase and transform it into a liquid phase. The cooling water of the cooler only cools, there is no phase change, just a pure temperature change; in addition, the cooling medium they use is also different. The purpose is also different. The cooler is used to cool the material without phas...

  Heat pump water heater, as the name suggests, is a device that uses the principle of heat pump to generate hot water. In principle, all heat pump water heaters adopt a thermodynamic reverse cycle. The refrigerant is driven by the compressor to absorb the heat of the external environment from the evaporator, and the condenser and the equivalent heat of the compression work are put into the heating unit. In the water. Today, the   heat pump water heater exporter   will introduce you to how to install a heat pump water heater. 1. The positioning of the unit and the location of the unit is determined mainly by considering the load-bearing capacity of the floor and the influence of the unit's air intake and output. 2. The foundation can be made of cement or channel steel, and the foundation must be on the load-bearing beam on the floor. 3. Placement adjustment to ensure stable placement of the unit, and a shock-absorbing rubber pad between the unit and the foundation. 4. The...

  Heat pump technology is a new energy technology that has attracted much attention all over the world in recent years. With the arrival of the new climax of industrial construction, heat pump technology has begun to be introduced into China. Factors such as rapid urbanization in coastal areas and per capita GDP growth have promoted the application of heat pumps in China. In this context, heat pump water heaters began to appear in our vision, bringing greater convenience to our lives. The   heat pump water heater  has the advantages of energy-saving, environmental protection, and safety of solar water heaters. It also solves the problems of solar water heaters relying on sunlight to collect heat and inconvenient installation. Combining these advantages, heat pump water heaters are the best solution for large, medium, and small hot water centralized supply systems in school dormitories, hotels, bathing centers, and other places. Of course, there are also safety issues that...

  High voltage alarm is one of the frequent faults of the chiller. There are many reasons, but the biggest reason is the reason for the cooling water system. The following is an analysis of the specific reasons and provides a simple solution. If your water  chiller  is air-cooled, please refer to the following for troubleshooting: The  air-cooled   chiller  condenser is used for cooling by the fan. The causes of high-pressure failure are as follows 1. Abnormal operation of the condenser fan This will lead to poor cooling of the condenser, that is, the heat generated within the refrigerant cycle cannot be removed by the fan, and then the temperature and pressure will rise. Just like when we blow the fan in hot weather, if the fan does not turn, we will continue to perspire, which is abnormal in heat and the high-pressure alarm will not occur. Solution: Check and repair the fan, remove dust and debris around the fan hood, after stopping, clean with compressed...
