The global market for these chillers was $1.5 billion in 2024. It will probably grow fast. More industries want better cooling.

Key Takeaways

Low temperature chillers help keep things cool in many places, like hospitals, food factories, and computer rooms. These chillers use refrigerant gas to take away heat. This helps control the temperature exactly and keeps important items safe. Picking the best chiller means you need to think about how much you want to store, what temperature you need, and how good the insulation is. This helps the chiller work well. You need to take care of chillers often to keep them working right. You should change filters and clean coils so problems do not happen. Using eco-friendly refrigerants like R290 can help the planet and still keep things cool.

Low Temperature Chiller Basics

How They Work

A low temperature chiller moves heat away from things. It uses a special refrigerant gas inside the system. The gas gets squeezed and then let go. When squeezed, the gas gets hot. When it is let go, it cools down. Then it takes heat from water, air, or equipment. This keeps your items or machines at the right temperature.

Did you know? The best place to separate liquid in the condenser tube is about one-third from the inlet. This helps the chiller work better and keeps cooling steady.

Here is a table that shows how pressure changes and performance get better in a low temperature chiller:

Key Findings	Description
Optimal Liquid Separation Point	About one-third the length of the condenser tube from the inlet.
Pressure Changes	64 kPa lower condensation pressure and 148 kPa higher evaporation pressure.
Performance Improvements	Heating capacity rises by 14.3% and COP increases by 12.6% as water temperature goes up.

Key Components

Low temperature chillers have many important parts. Each part has a job to help cool things down.

Compressor: This part squeezes the refrigerant gas. It makes the gas hotter and raises the pressure.
Evaporator: Here, the refrigerant spreads out and cools down. It takes heat from the water or air you want to chill.
Condenser: The refrigerant lets go of heat here. The condenser helps the gas turn back into a liquid.
Expansion Valve: This valve controls how much refrigerant goes into the evaporator. It helps keep the temperature steady.

Some chillers use new technology today. For example, Trane’s Computer Room Air-Handler helps cool data centers with better control. The Tracer®SC+ system controller makes it easier to manage the chiller. Johnson Controls’ YORK® YVAM Air-Cooled Magnetic Bearing Chiller uses less power and no water. This helps save energy and protect the environment.

Types of Chillers

There are different types of low temperature chillers. Each type works in its own way and fits different needs.

Centrifugal Chillers: These chillers use spinning wheels to move refrigerant. They work well for big spaces and large cooling jobs.
Absorption Chillers: These chillers use heat or steam instead of electricity. They help save energy, especially if you have extra heat from other machines.
Air-Cooled Chillers: These chillers use air to cool the refrigerant. They are easy to set up and work well where water is hard to get.
Water-Cooled Chillers: These chillers use water to take away heat. They work best in big buildings or factories.

You should think about the environment when picking a chiller. Many low temperature chillers use R290 (propane) as a refrigerant. R290 has a very low global warming potential, so it is better for the planet. Chillers with DC inverter micro-compressors can save about 3,000 kWh of electricity each year. R290 is mildly flammable, so you need good safety systems and regular checks.

Tip: If you want a chiller for a small space, look for compact models that use R290. These chillers work well for commercial refrigeration and save energy.
