 According to the Department of Energy (DOE), chillers consume around 20% of the country's total electricity production. What's more, they can add up to 30% of a building's additional energy use due to operational inefficiencies. This costs companies and building facilities billions of dollars every year. Today, commercial buildings are fitted with highly efficient HVAC systems designed to improve the sustainability and performance of the building. This brings us to  water-cooled chillers , which are an essential HVAC component for a variety of commercial facilities. Read on to find out more about water-cooled chillers and whether it's right for your facility. Features of a water-cooled chiller Water-cooled chillers are the chillers of choice for power plants and other large facilities with a steady water supply.        Flooded Type Screw Type Chiller In particular, chillers help to transfer heat from the internal environment to the external environment, ma...

  Chiller performance  varies greatly with operating conditions. Full-load performance is not a good indicator of overall performance because chillers rarely operate at full load. Instead, part-load performance is critical to good overall chiller performance. Refer to ASHRAE Standard 90.1-2001, which lists minimum chiller efficiency requirements. There are several variables that can affect the efficiency of a chiller.   1. Controlling the flow rate The flow rate must be closely regulated, as too low a flow rate can reduce the efficiency of the chiller, resulting in laminar flow. The minimum flow rate is usually about 3 feet per second. However, excessive flow rates can cause vibration, noise and pipe corrosion. The recommended maximum flow rate is usually about 12 feet per second.   2. Keeping the Refrigerant Charged The amount of cooling any cooler can provide depends on the amount of refrigerant it passes through the compressor per unit time. It is important to mai...

  A chiller or   chilled water system   is a type of refrigeration system that uses water as a secondary refrigerant. They are used in larger and more complex heating, ventilation, air conditioning and refrigeration (HVACR) applications. Typical applications for chillers are listed below.   ㆍ District cooling ㆍ Central air conditioning ㆍ Hydroponics ㆍ Food and beverage processing ㆍ Pharmaceutical and medical ㆍ Cold Storage ㆍ Thermal Energy Storage (TES) systems ㆍ Machining, waterjet cutting, laser cutting, welding, etc. ㆍ Plastic processing    Water Cooled Screw Chiller As opposed to chillers, direct expansion (DX) refrigeration systems cool air directly from the room or enclosed space without the use of secondary refrigerants. The DX type is more suitable for smaller applications, such as residential space cooling and small freezers and refrigeration units.   Principle of operation Chiller systems  consist of two main loops or circuits. These are...

  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...
