Today, both condensers and coolers are very important heat exchange components in commercial or industrial refrigeration equipment and are widely used in many applications. Many customers are curious about the difference between a condenser and a cooler.  There are four 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. Fourthly whether there is a liquid level control port. Today the  chiller supplier  will talk about this aspect. 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 phase change. The condenser is used ...

A chiller is a machine that removes heat from a liquid coolant via a vapor-compression, adsorption refrigeration, or absorption refrigeration cycles. This liquid can then be circulated through a heat exchanger to cool equipment, or another process stream (such as air or process water). As a necessary by-product, refrigeration creates waste heat that must be exhausted to ambience, or for greater efficiency, recovered for heating purposes. Chilled water is used to cool and dehumidify air in mid- to large-size commercial, industrial, and institutional facilities. Water cooled chillers can be liquid-cooled (through cooling towers), air-cooled, or evaporatively cooled. Water or liquid-cooled systems can provide efficiency and environmental impact advantages over air-cooled systems. Flooded Type Screw Type Chiller Chillers are widely used as portable cooling systems in commercial and industrial facilities. In simple terms, industrial chillers can be thought of as cooling systems that c...

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 connection of ...

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. Portable Chiller 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 heat to the outside of ...

There are kinds of chillers, such as Air Cooled Scroll Chiller, auto water cooled Chiller and others. But whatever the chiller is, there are some factors affecting the cooling capacity of chillers. Air Cooled Scroll Chiller A chiller is an energy-saving machine that achieves refrigeration by steam compression or absorption cycles. What are the factors that affect the cooling capacity of the chiller? Let us introduce it to you. Factors affecting the cooling capacity of the chiller: 1. Compressor power: The higher the power, the higher the cooling capacity. According to the size of the model, the compressors of different types are selected. For example, the small chiller is piston type, the medium type is equipped with scroll type, and the large type is screw type. , centrifugal and so on. 2. Water temperature (evaporation temperature is different, cooling capacity is different): The higher the water temperature, the larger the cooling capacity, and the lower the water temperature, the ...

Commercial chiller  repair can be an expensive and time-consuming process if you don't know what you're doing. However, with this guide, you will learn how to properly diagnose and repair your industrial chiller to get it working at full capacity again.   Commercial Chiller Repair and Maintenance Tips Commercial chiller repair is an important part of any chiller owner's job. There are many reasons why industrial chillers fail, but they can be prevented with a few simple steps.   Perform routine maintenance on a quarterly basis. Your  chiller manufacturer  should provide you with a chiller checklist as a guide. If optional, you should join your customer's preventive maintenance program. Always use a licensed HVAC company for maintenance and repairs, and keep maintenance and repair records for future reference.   Inspect the heat transfer fluid to ensure it is free of debris and properly rated for ambient conditions and process fluid temperature. Then, check ...

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, making ...
