120kw chiller

Types of 120kw chillers

A chiller is a piece of machinery used to cool something, typically a liquid. Basically, chillers are heat-extraction devices that are used to remove heat from a liquid through a vapor-compression or absorption refrigeration cycle. 120kw chillers are industrial cooling machines used to remove heat from a process. These types of chillers usually come in two main categories: air-cooled 120kw chillers and water-cooled 120kw chillers.

• Air-cooled 120kw chiller

  Using ambient air as the cooling medium, the heat generated during the refrigeration cycle is expelled into the air. 120kw air-cooled chillers come in various forms and may use axial or radial fans, and they are usually placed outside of buildings.

• Water-cooled 120kw chiller

  A water-cooled chiller uses water as the medium that absorbs heat. Usually, a secondary or evaporative water system is employed. 120kw water-cooled chillers are usually installed indoors, however, they require a separate cooling tower or water heat sink.

Specifications and maintenance of a 120kw chiller

The following are key specs for business owners to pay attention to when purchasing a large-scale chiller.

• Cooling capacity: This capacity ranges from 10pw to 250kw. It indicates how much heat the chiller can remove from the surrounding air or liquid per unit of time.
• Compressor type: Factors such as the refrigerant gas used and the required maintenance may influence the choice of the compressor type. Common compressor types are scroll, screw, reciprocating, and centrifugal compressors.
• Refrigerant type: The performance and environmental impact of a chiller can be affected by the kind of refrigerant used. Common refrigerants are R-22, R-134A, R-410A, and ammonia (R-717).
• Operating voltage: This is the voltage at which the chiller operates. It is usually in the range of 200 to 600 volts. Some manufacturers may offer it up to 1,000volts.
• Energy efficiency ratio (EER): The EER compares the cooling output with the electrical input. A higher EER rating shows better energy efficiency on the part of the chiller.
• Noise level: The noise level is measured in decibels (dB). It indicates how noisy the chiller may be during operation. Installing a very noisy chiller can lead to complaints from nearby residents and customers.
• Dimensions and weight: This is important for determining the installation needs of the chiller. These may include the number of required pipes, valves, and electrical connections.

Maintenance tips

Business owners should consider regular service and maintenance. This is important for the optimal performance, reliability, and longevity of the large-scale chiller. Here are some tips for 120kw chiller maintenance:

• Check the air filter monthly and replace it if it is dirty or clogged.
• Inspect the condensate drain for clogs or blockages.
• Check for any visible refrigerant leaks.
• Check the settings of the thermostat to ensure they are accurate.
• Ensure that all fan blades are free from debris and dust.

Usage scenarios of 120kw chillers

These large capacity chillers can be used in the following industries and applications:

• Food and beverage industry: 120kw chillers provide consistent low-temperature cooling for food production, processing, preservation, and beverage bottling, ensuring food safety and quality.
• Pharmaceutical and chemical industry: These chillers control reaction temperatures, cool down products, and maintain the stability of raw materials in chemical production, ensuring product quality and meeting regulatory standards.
• Facility management: They offer precise temperature and humidity control for commercial buildings, data centers, and cleanroom facilities, creating comfortable and safe working environments.
• Process engineering: 120kw chillers support various engineering processes such as laser cutting, supercritical extraction, and molecular distillation by providing stable and efficient cooling, enhancing production efficiency and product quality.
• Plastic and rubber industry: They swiftly cool down plastic and rubber products during the molding and extrusion processes to improve production efficiency and product quality.
• HVAC industry: 120kw water chillers are a key component in central air conditioning systems, providing comfortable cooling for large indoor spaces.

How to Choose 120kw chillers

There are several things to note before purchasing an industrial chiller. This includes the working environment and business parameters. Let's discuss these factors in detail:

• Cooling Load Requirement

  /Size of the business: It is important to evaluate the level at which heat is generated within the building or facility. This includes the impact of weather changes, insulation, the number of people in the building, and other factors that affect the occurrence of cooling needs and the amount of cooling needed. Understanding these things will help determine the appropriate chiller capacity, like a 120kw water chiller.

• Chiller System Types

  There are various types of chillers, including air-cooled and water-cooled, reciprocating, screw, absorption, centrifugal chillers, etc. Each has distinct features, working principles, advantages, and shortcomings. For example, a water-cooled chiller works better in a high-heat situation because it can dissipate heat quickly. On the other hand, water-cooled chillers require a cooling tower and water for heat rejection. This makes them unsuitable for areas with limited water resources. An in-depth understanding of these systems will help to pick the right chiller that will satisfy the requirements of an application.

• Energy Efficiency

  Because industrial chillers consume a lot of energy, it's important to select a chiller system with an effective energy use ratio (EER) or coefficient of performance (COP). These two parameters indicate a chiller's cooling output per watt of energy used. A chiller with a high EER/COP is energy-efficient and will help reduce electricity bills.

• Environmental Impact

  Since industrial chillers contribute significantly to a business's energy usage, choosing a chiller with a low global warming potential (GWP) refrigerant is essential. Refrigerants with a high GWP can significantly impact climate change when they leak into the atmosphere.

• Installation, Operation, Maintenance, and Service Support

  Operating and maintaining a chiller will cost a business more than the initial investment. Therefore, it is important to consider the costs of these two factors. Choose chillers that are easy to maintain, operate, and install, and settle for a manufacturer that provides excellent after-sales support.

FAQ

Q1: How is the performance of a 120kw chiller measured?

A1: The performance of a 120kw chiller is typically measured by its cooling capacity, which is the amount of heat it can remove from a space or process per unit of time. Cooling capacity is usually expressed in kilowatts (kW) or tons.

Q2: What are some environmental considerations associated with 120kw chillers?

A2: When selecting a chiller for use, both the refrigerant it uses and the chiller's energy efficiency need to be evaluated thoroughly. This is because they directly affect the environment. It is preferable to choose a chiller that uses a refrigerant with a low global warming potential (GWP) and to opt for highly energy-efficient chillers to minimize greenhouse gas emissions resulting from energy production.

Q3: What are the differences between air-cooled and water-cooled 120kw chillers?

A3: In general, an air-cooled chiller is more suitable for small to medium-sized applications or when the installation site has limited space. Conversely, a water-cooled chiller is more suitable for large-scale facilities or applications that require high cooling capacities.
