What Is an Air Cooled Screw Chiller

System Overview

An air cooled screw chiller helps keep things cool. It uses screw compressors and has two compressors. This design gives steady cooling all day. The chiller takes heat from water or air. Fans push the heat outside. You do not need a cooling tower. This saves space and makes it easy to set up.

You can look at the table to see how air-cooled chillers and water-cooled chillers are different:

You can put an air cooled screw chiller outside. This makes it a good pick if you want simple cooling.

Key Features

Air-cooled chillers have many helpful features. Two compressors let you use full or part power. This saves energy and keeps things working well. Cooling power can be from 10 to 200 tons. Some models can cool even more, from 20 to 850 tons.

You can set the temperature with a smart PLC system. This helps you pick the cooling you need. The chiller uses safe refrigerants that help the planet. Strong materials stop rust and make the chiller last longer. Many chillers have safety features like alarms and overload protection. These help stop problems and keep your system safe.

Tip: If you want a cooling system that is easy to set up, saves water, and gives you flexible cooling, an air cooled screw chiller is a smart pick.

Main Components of Air Cooled Screw Chiller

Screw Compressor Technology

You get strong cooling power from the screw compressor. This part uses a special rotor tooth profile that boosts performance. The 5:6 asymmetric rotor design helps the compressor run smoothly and quietly. You see less vibration and noise. The compressor uses a built-in hydraulic system. This system keeps the oil clean and the parts moving well. You do not need an extra oil pump. The compressor lasts longer because it has strong bearings and a balance drum. These features help your chiller work for many years.

Dual Compressor Design

You can count on steady cooling with the dual compressor setup. The chiller switches between full and partial load modes. This means you use only the energy you need. If your building needs less cooling, one compressor can rest while the other works. This saves power and keeps your system running without stops. The dual design also gives backup. If one compressor needs service, the other keeps the air cooled screw chiller working. You get reliable performance every day.

Air Cooled Condenser and Fans

You do not need a cooling tower with this chiller. The condenser and fans push heat into the air outside. This design makes installation simple. The fans move air over the condenser coils. The coils use corrosion-resistant materials. This helps the chiller last longer, even in tough weather. You can choose low-noise fans if you want a quieter system. The condenser and fans work together to keep your chiller’s performance high.

Evaporator and Expansion Valve

The evaporator and expansion valve help your chiller absorb heat and cool your process fluid. Their design affects how well your system works.

• The evaporator pulls heat from the fluid. Good design means better heat absorption and higher performance.

• You can pick from shell-and-tube or plate-and-frame evaporators. Each type fits different needs and boosts efficiency.

• The expansion valve controls how much refrigerant enters the evaporator. This keeps the cooling steady and helps your chiller run at its best.

Tip: Smart controls and flexible refrigerant options let you adjust your chiller for different jobs. You get the right performance every time.

How Air Cooled Chillers Work

Refrigeration Cycle Steps

Air cooled chillers use a simple process. The refrigeration cycle has four main parts. Each part helps move heat and keeps things cool.

• The compressor makes the refrigerant have more pressure.

• The condenser takes heat out of the refrigerant vapor.

• The expansion device lowers the pressure fast.

• The evaporator grabs heat from the air or water.

The compressor pushes the refrigerant through the system. Fans in the condenser blow air over coils. This sends heat outside. The expansion device cools the refrigerant quickly. The evaporator takes heat from inside your building. The cycle keeps going to keep the temperature right.

Note: You do not need a cooling tower for air cooled chillers. This makes it easier to install and saves time.

Heat Absorption and Release

You can see how air cooled chillers work by watching heat move. The evaporator takes heat from water or air. The refrigerant inside the evaporator grabs this heat. The compressor sends the hot refrigerant to the condenser. The condenser and fans push heat into the outside air. This step cools your building.

The process repeats again and again. The expansion device drops the pressure of the refrigerant. This makes the refrigerant cold again. The cold refrigerant goes back to the evaporator. You get steady cooling because the cycle does not stop.

Tip: You can use air cooled chillers where water is hard to get. The system does not waste water.

Air Cooling Mechanism

You learn about air cooled chillers by looking at the air cooling part. The fans are important. They blow air over the condenser coils. This air takes heat away from the refrigerant. You do not need water for this step. The design lets you put the chiller outside.

The air cooling part helps you save money on repairs. You do not have to clean or change cooling towers. The fans and coils use strong materials that do not rust. You get good cooling for many years.

If you want a system that is easy to set up and take care of, air cooled chillers are a smart pick.

Now you know how air cooled chillers work. The refrigeration cycle, heat absorption and release, and air cooling all work together. You get good cooling without extra water or hard equipment.

Efficiency and Benefits

Energy Savings and Partial Load Operation

An air cooled screw chiller helps you save energy every day. It has two compressors. You can use both or just one. If your building does not need much cooling, the chiller uses less power. Smart controls let you pick the right temperature fast. Your electricity bills go down because the chiller does not waste energy. The chiller switches between compressors to give the cooling you need. This keeps your system working well and steady.

Tip: You can use up to 30% less power than chillers with only one compressor.

Reliability and Longevity

Air cooled chillers give you cooling you can count on for years. They are made with strong materials that do not rust or break easily. The compressor has a special rotor and strong bearings. These parts help the chiller last more than 15 years. You do not need a cooling tower, so you have fewer repairs. The smart PLC system checks for problems and sends alerts. You can trust air cooled chillers to work even in hard places.
