  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 connectio

  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 need our atte

  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 air or water gun. 2.   Conde

  Condensers of   screw chillers   are extremely easy to foul and reduce heat exchange efficiency, so it is very important to clean the condenser of screw chillers. First, reasons for the cleaning of the condenser of the screw chiller: The condenser of the screw chiller is very easy to scale. Normally, daily water treatment should be done during the cooling period in the summer. Otherwise, if it is operated in a high hardness water environment, the inorganic salt dissolved in the water in the circulating water system will rise with the temperature. High crystal precipitation, scale formation on the tube wall of the condenser heat exchange surface, resulting in reduced heat exchange efficiency. At the same time, if the hard scale increases, the energy consumption will increase. When the hard scale is 1mm thick, it will increase by 6%-8%. In addition, due to the dirt, silt, and humus in the water, the biological slime formed by bacteria, algae, and other microorganisms and their secretio

  In large-scale ice water chillers such as   industrial water chillers , explosion-proof screw water chillers, low-temperature water chillers (adjustable from -40°C to -5°C), special water chillers for the electroplating industry (acid and alkali resistant), and other products have been doing the following tests and provide personnel to the site to guide the installation. The connection method of the refrigerant pipe. Before connecting the chiller to the pipe of the system, we must first release the nitrogen stored in the chiller (the pressure is about 0.5bar). The requirement for the refrigerant system is that it must maintain a high degree of cleanliness, so the inside of the chiller must be dry and clean, with no deposits, and no oxygen. During soldering, dry nitrogen, use low-melting silver-copper alloy solder, and control its melting degree to reduce the generation of dirt in the pipeline. There are two other situations that can cause fouling. 1. The refrigerant remaining in the
