Direct Cooling Solutions

Our first event as Direct Cooling Solutions

Direct Cooling Solutions — 28/10/2024

We exhibited at Maintec this June with our sister company Direct Air and it was a huge success for both as we had the opportunity to connect with both existing and new customers!

We were thrilled to have the chance to showcase Direct Cooling alongside Direct Air at Maintec this June. It was a great opportunity to meet some new faces and familiarise those who aren’t familiar with our services about the industrial cooling solutions we can offer.

In addition to meeting potential new customers, we also had the chance to meet with some of our existing customers. It was great to hear their feedback and discuss how we can continue to meet their needs and expectations.

Lets take a look into how this year’s event went…

Our 3 hot topics from Maintec:

Parker products

As this year was Direct Cooling Solution’s first time on the stand, we were excited to talk about chiller and cooling solutions more than ever.

Direct Cooling are authorised distributors for Parker’s Hyperchill Plus (ICEP) and Hyperchill (ICE) range of chillers. The ICEP & ICE range of chillers are versatile and flexible to meeting your process cooling requirements, delivering cooling capacity from 1.7 to 760 kW.

Chillers

We can provide many chiller packages / options and work with you to find the best solution for your application.

Chillers are widely used throughout Industrial, Healthcare, Data Centre and HVAC (Heating, Ventilation and Air Conditioning) applications for a wide range of uses from cooling injection moulding machine tools to air handling units. They do this by providing chilled fluid generally anywhere between -10°C to +20°C to various items such as heat exchangers and cooling coils within the process or air conditioning equipment.

Ambient Cooling

The ambient cooling products that we can offer range from dry air coolers, adiabatic coolers, free coolers and cooling towers.

The main benefits of this type of product is that they are more energy efficient than products with refrigeration circuits such as a chiller that require compressors to compress the refrigerant as part of the refrigerant cycle and are simpler, with less mechanical and electrical components.

And not to mention our very own magician, Tom!

Overall, Maintec 2024 was a fantastic event for Direct Air and Direct Cooling. We are grateful to everyone who took the time to visit our stand, whether they were existing customers or new connections. The support and interest we received at Maintec was fantastic, and we are excited about the possibilities that lie ahead as a result of this event.

How do chillers work? Everything you need to know

Direct Cooling Solutions — 28/10/2024

A chiller is a machine designed to cool down water, or water / glycol solution to a precise temperature using a refrigeration circuit.

Chillers are commonly used in industries such as food processing, data centres and manufacturing to regulate temperatures effectively. They are essential to operations that require consistent and reliable temperature control to secure the quality and stability of products and processes.

Our chillers work on the principle of the vapour compression cycle. There are two types of chillers, either air cooled, or water cooled. Read our full blog to read more about these technology types as well as the vapour compression cycle.

Types of Chillers and Their Mechanisms

Air-Cooled Chillers: Air cooled chillers use air that is passed through the condenser by the use of fans to extract heat from the condenser.

Water-Cooled Chillers: Water cooled chillers use a secondary water circuit that is pumped through the condenser to remove heat from the condenser.

Now let’s look at the vapour compression cycle...

The chiller pumps water, or water / glycol solution to the process application where heat is extracted from the application into the cooling fluid that then returns to the chiller. The chiller has a refrigerant circuit that consists of four main components: evaporator, compressor, condenser, and thermostatic expansion valve (TEV).
The evaporator is a heat exchange device that absorbs the heat from the cooling fluid into the refrigerant and causes the refrigerant to evaporate and become superheated vapour.
This superheated vapour at low evaporating pressure is then compressed by the compressor into superheated vapour at a higher condensing pressure.
It then enters the condenser, rejects the heat at high pressure, whilst desuperheating and condensing into a high-pressure liquid. The condenser is another heat exchange device and the rejected heat from the refrigerant is absorbed by the air (air cooled chiller) or water (water cooled chiller) that passes through the condenser.
Expansion of the refrigerant then takes place at the thermostatic expansion valve and the high-pressure liquid lowers to an evaporating pressure liquid and enters the evaporator completing the cycle.
Through this process, the cooling fluid is continually cooled and returned to the process application at the required temperature set point due to the correct staging of the compressor and modulation of cooling across the condenser.

How Do Chillers Work?

Chillers operate using a refrigeration cycle, consisting of 4 key steps:

Compression: The compressor raises the refrigerant gas’s pressure and temperature, initiating the cooling process.
Condensation: The high-pressure gas moves to the condenser, where it releases heat through a heat transfer process and turns into a high-pressure liquid. During this phase, the refrigerant condensing temperature is a critical factor in determining the efficiency of the heat exchange.
Expansion: The liquid refrigerant then passes through the expansion valve, causing a drop in pressure and temperature.
Evaporation: This low-pressure liquid enters the evaporator, absorbing heat from the surroundings and converting back into a low-pressure gas. The cycle then repeats.

Key Components of Chillers

Compressor: The heart of the chiller, it compresses the refrigerant, increasing its pressure and temperature.

Condenser: This component allows the high-pressure gas to release heat and condense into a high-pressure liquid. The refrigerant condensing temperature is crucial here for efficient heat transfer.

Expansion Valve: It reduces the pressure of the liquid refrigerant, causing it to cool down.

Evaporator: Here, the refrigerant absorbs heat from the process water or air, cooling it down before returning to the compressor to repeat the cycle.

Benefits of Using Chillers

Energy Efficiency: Modern chillers are highly energy-efficient and can significantly reduce operational costs.

Consistency and Reliability: They provide consistent cooling, which is crucial for processes that require precise temperature control.

Flexibility: Chillers come in various sizes and configurations, making them adaptable to different needs and environments.

Longevity: With proper maintenance, chillers can have a long operational life, providing reliable cooling for many years.

Applications of Chillers in Industry

Industrial chillers are required in various industrial settings, providing effective cooling solutions for operations in manufacturing, pharmaceuticals, and chemical processing. By removing excess heat, an industrial chiller helps preserve product quality and enhance operational efficiency. They are critical for controlling the temperature of equipment and machinery in demanding environments. For instance, in plastic manufacturing, chillers cool the hot plastic that is injected, blown, extruded, or stamped.
