  Like any critical piece of equipment in a commercial facility, chillers require regular maintenance to maintain efficient and effective operation. A poorly maintained chiller can add 10% or more to the cost of running the system, which is likely already one of the largest consumers of power in your facility.   Whether you use a traditional scheduled maintenance program or modern technology to monitor your chillers for on-demand maintenance needs,  regular chiller maintenance  makes sense from a performance and cost perspective. Here are nine tips you can use to enhance your chiller's regular maintenance and keep this vital piece of commercial equipment in the best and most economical condition.   Keep a daily log: A daily log of  chiller operation  will create a historical record that will give you an idea of equipment operating trends that may affect chiller maintenance needs. Record information such as operating temperature, liquid level, flow rate...

  Industrial processes generate a lot of heat, which must be dissipated to avoid damage to sensitive equipment and to protect the finished product. A proven method of monitoring and regulating temperatures to optimum levels involves the use of cooling systems that can be water or air cooled. This article will focus on the differences between  water cooled chillers  and air cooled chiller systems.   Air cooled chillers versus water cooled chillers Although both  air-cooled chillers  and water-cooled chillers remove unwanted heat from the manufacturing process, they differ in many ways. Deciding which chiller is best for your industrial application depends on several factors, such as   Chiller condenser mechanism Cost difference between water and air-cooled Chiller capacity range Environmental and location considerations   Air-cooled vs. water-cooled condensers There is a clear difference between air-cooled chillers and water-cooled chillers with co...

 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 c...

  There are two types of chillers:  portable chillers  and central chillers. Next, the  chiller supplier  will share with you. Portable chillers Portable chillers typically have smaller capacities (30-40 tons or less), simpler overall designs, and lower installation costs. Equipped with casters, they are easy to move, easy to connect (using flexible hoses) and easy to start. Portable chillers are often optimized to provide a fixed amount of heat transfer capacity (in tons). They are ideal when a piece of process equipment requires a cooling stream at a significantly different temperature than the rest of the equipment. Typically, portable refrigerators operate most efficiently when the cooling load is closely matched to the rated capacity of the refrigerator. DC series small chillers use a  DC power supply , using coolant as the heat transfer medium, transferring heat generated by other instruments or equipment that need to be cooled, and dissipating h...

  1. Increased energy consumption If the compressor is running at low pressure, the motor load will become smaller, and a  chiller  with a low-pressure failure will waste electricity under the same cooling conditions. 2. Smaller cooling capacity If the chiller suction pressure is low and the return air volume is reduced, the cooling capacity will not reach the target.   What are the causes of low chiller pressure? How to solve? 1. Insufficient refrigerant or leakage Insufficient refrigerant will lead to system pressure failure, resulting in lower suction pressure. The chiller will issue a low pressure alarm and the unit will stop. Solution:  The refrigerant leakage part can be diagnosed from the piping connection of compressor, condenser, filter, expansion valve, evaporator and other accessories. After troubleshooting, charging the right amount of refrigerant can solve the problem.  Water Cooled Screw Chiller   2. Low ambient temperature When the outsi...
