Your Guide to Different Types of Cooling Systems and How They Work

If you’re new to the world of cooling systems, it can be hard to know which one to choose. There are a variety of options and different solutions are more suited to certain businesses or locations. When choosing which system you want for your business it is useful to know what options are out there, and just how they work. This way you can be sure you are full informed before making any decisions. During the warmer months, ensuring your employees are comfortable in their workspace is important as the hot weather can be detrimental to productivity. In the hopes of helping you decide what is best for your business, we’ve put together this handy guide to the different types of cooling systems and how they work.

Before you move on to deciding which cooling system is best for you, it is important you consider the cooling duty you require from the solution you choose. The required cooling distance of any space is worked out based on a number of factors, including; the size of the space, the number of people in it and the number of heated appliances present such as laptops and printers.

Evaporative Coolers

Evaporative coolers differ from standard air conditioning units as they don’t require ventilation to work. They are therefore a great option for any offices, buildings, factories or warehouses which do not have open windows. They come in a variety of different sizes to suit different cooling duty requirements and workspace environments. Evaporative Coolers are especially popular in hot and dry climates such as certain places in the United States and Australia.

How They Work

Evaporative coolers work by using the process of evaporation to cool the air rather than a refrigeration process. They have a fan in the unit which pushes hot air across a cooling media; as this occurs evaporation begins, and this process starts a heat transfer which cools the air and moves it back into the environment.

Air Conditioning Units

Air conditioning units are generally the first choice for cooling in an office setting, and other working environments where ventilation is present. There are two main types of air conditioning units; exhaust tube air conditioning and split type air conditioning. Unlike evaporative coolers they do rely on the process of refrigeration.

How They Work

Exhaust tube units are considered to be very practical and cost effective, making them a common choice for most businesses. They work by pulling hot air in through grills on the exterior of the unit, this air is then moved through the unit and through a refrigeration cycle where heat transfer cools it and then it is pumped out of the front of the machine into the environment which needs cooling. Alternatively, there are split type air conditioning units, they work in a similar way but are made up of two components – one of which is placed inside and the other outside. This means inside there is little to no noise disruption from the unit. Split type units are generally more efficient but tend to be more expensive, they are more flexible as they tend to have longer connectors to their outside components.

Cooling Fans

There are a variety of sizes in cooling fans, from smaller fans which are great for offices to larger industrial fans which can be put to use in warehouses and factories.

How They Work

Cooling fans provide high performance cooling in commercial and industrial settings. In addition to cooling the air, they can also be used to moved around steam and dust in factories and warehouses which can be very beneficial. They are portable and therefore easier to move around as you please.

Chiller Hire Services

Chillers are a good choice for any larger industrial, commercial and institutional facilities. They are available in a variety of cooling duties ranging from 5kW to 750kW. These large chillers can serve a number of purposes from large scale air conditioning to cooling drinking water and maintaining the temperature of machinery. They are often used in food, drink and chemical industries to keep products cool or serve as back-ups for permanent chillers. In addition to being a great option for large offices and factories they can also be used for temporary events.

How They Work

They comprise of the compressor, condenser, expansion valve and evaporator and are referred to as vapour compression refrigeration systems. The purpose of a chiller is to remove heat from somewhere it is not wanted, to do this it pulls in the heat using a refrigerant which then carries this heat to a condenser where it is sent into the atmosphere by means of an air, evaporation, or water cooled heat exchanger. After the refrigerant has left the condenser it is compressed which in turn lowers the temperature and then it is sent back to begin the process again.
