Commercial small water chiller

Types of commercial small water chillers

A commercial small water chiller refers to a refrigeration device designed to lower the temperature of water and therefore provide cooling. It plays an essential role in various commercial and industrial applications.

Water chillers can be classified into two main categories: air-cooled and water-cooled chillers.

• Air-cooled chillers:

  An air-cooled chiller uses the ambient air to dissipate heat through the condensation process. The machine is equipped with integral or external fans and heat exchangers, which let the air pass through and cool the refrigerant. Then, the heat is removed from the water. The air-cooled chiller works especially well in smaller commercial spaces where there is limited access to large amounts of water. It's worth mentioning that an air-cooled chiller uses less water and energy compared to its water-cooled counterparts. Additionally, it doesn't require complex maintenance tasks or water treatments to function optimally.

• Water-cooled chillers:

  As the name suggests, water-cooled chillers use water to remove heat from the refrigerant during the condensation process. Generally, chilled water is sent to heat exchangers or cooling coils, where heat from different equipment or spaces is absorbed. To do so, the water-cooled chiller is required to be set up with a cooling tower or a large water reservoir. Because of this, the water-cooled chiller has a higher cooling capacity, making it suitable for large commercial and industrial buildings. Water-cooled chillers are usually found in air conditioning systems for big buildings.

Water chillers can also be categorized according to their cooling capacities and ways of processing water.

• Screw chillers:

  Screw chillers utilize twin-screw compression technology to cool water. They are specifically designed to handle high volumes of water and heat.

• Scroll chillers:

  Scroll chillers utilize scroll compressor technology to cool water, which offers a smooth and continuous compression process. The benefits are precise temperature control and minimal noise.

• Air-water chiller combo units:

  It is a combo unit that integrates both air cooling and water cooling into one system. While it's not that common, it can be used for certain occasions and offers a flexible cooling solution for people to choose from.

• Portable/dehumidifying water chillers:

  A portable water chiller is a compact chiller that can be moved from one place to another with ease. Usually, wheels or casters are installed on the bottom of the machine to help with the mobility. Moreover, portable water chillers offer instantaneous cooling solutions without the need for complex installations. Dehumidifying water chillers are designed to not only cool water but also extract excess moisture from the air. It helps reduce humidity levels and improve precision control over processes and comfort in space indoor.

Specification and Maintenance

To ensure business owners select the right commercial small water chiller for their specific applications, it is crucial to understand its essential features.

• Cooling Capacity

  The ability of the chiller to remove heat is described in terms of its cooling capacity. It is often stated in kilowatts (kW) or BTUs per hour. Different industries require chillers with distinct cooling capabilities.

• Temperature Range

  Chill water should maintain a specific temperature range to do its work effectively. Most commercial small chillers can regulate temperatures between -5°C and 10°C.

• Compressor Type

  A small commercial water chiller uses different compressor types to manage refrigerant gases and facilitate heat exchange. Scroll compressors are commonly used in small chillers due to their efficiency and reliability. Some scroll compressors feature variable-speed technology to match the cooling capacity to the changing load demands. Other types include reciprocating compressors and screw compressors.

• Condenser Type

  A condenser removes heat from the refrigerant as it circulates through the system. Air-cooled and water-cooled condensers are the most common types found in commercial water chillers. A water-cooled condenser is more efficient than an air-cooled one, which is more compact.

• Power Consumption

  This specifies the chiller’s energy usage in kilowatts (kW). Selecting an efficient chiller helps to lower operational expenses.

• Modularity

  Some chillers have modular designs, allowing businesses to easily add more chillers to meet increasing demands.

Maintenance

A commercial water chiller requires regular maintenance to operate optimally and extend its service life. Here are some important water chiller maintenance tips.

• Routine Inspection

  Schedule frequent inspections by certified technicians. Regular inspections prevent unexpected system failures and reduce downtime.

• Clean Condenser Coils

  Dirt and debris accumulate on the condenser coils over time and block heat transfer. This can cause the system to overheat and breakdown. Cleaning the coils regularly prevents this.

• System Controls

  Allow a qualified expert to monitor the chiller control system at least once every three months. The technician should examine the refrigerant pressure, temperature settings, and system alarms. Promptly adjust the settings or address any alarms to enhance the system’s performance and efficiency.

• Replace Filters

  The water chiller's filters prevent dirt and debris from entering the system. Clogged filters restrict airflow. Replace them to maintain proper system airflow and cooling.
