An Essential Insight Into Chiller Systems


Heaters and coolers are commonly used for various applications. This includes air conditioning systems as well as industrial cooling units for the storage of food & dairy products. Chillers are an essential component of an HVAC system as well as cooling units to store food products. They are used in many types of commercial facilities like hotels, restaurants, hospitals, sporting arenas, dairy farms, and more. It also happens to be the device that consumes a large amount of electrical energy and is the reason for high electricity bills. It is essentially the heart of any cooling unit. This article goes on to provide an essential insight into the air cooled chiller system.

Types of chiller systems

There are mainly two different cooling mediums: air and water that facilitate the transfer of the heat dispensed by the refrigerant as it converts vapour to liquid. A chiller can thus be water-cooled or air-cooled. An air-cooled condenser resembles a radiator while water-cooled which requires a two-step process for heat transfer is different.

How does it work?

The main concept of a chiller is that it provides a continuous flow of coolant to maintain the temperature at a low 10 degrees C. This coolant is pumped to extract the heat and allow it to flow back to return to the system. It uses a vapour compression mechanical refrigeration system. This connects to the water system via the vaporator. The refrigerant circulates through the evaporator, compressor, condenser, and expansion sections. The heat exchange takes place in the evaporator where the refrigerant evaporates changing from low-pressure liquid to vapour. This allows the main system to cool down in the process.

The water-cooled chillers will implement a water-cooled condenser with a cooling tower. On the other hand, an air-cooled chiller is cooled using the environmental air. Air-cooled systems will usually be the smaller systems while the water-cooled systems are meant for the bigger systems. Water-cooled chillers tend to offer a more constant performance and range from small size to those of high capacity ones. In the case of larger installations, water-cooled chillers would be the only option.

Common applications of a chiller 

There are various applications of this type of system. It is extensively used at restaurants since they tend to have high cooling requirements for food items. Shopping malls need to maintain a comfortable temperature at all times for the sake of their customers, chillers are often implemented to keep the temperature low. Several industries tend to generate a high amount of heat; chillers are essential to keep the temperature low. Some of the other applications of this type of system include that in dairy farms, viticulture, aquaculture, brewery, manufacturing industries, domestic air conditioning, commercial air conditioning, cool rooms and many more. 

Benefits of investing in an air Cooled Chiller system for your business 

Investing in a chiller is highly beneficial for many types of businesses since it can reduce operating costs by a big margin. Such systems are easy to maintain. They are vital for the proper functioning of many industries, for example, they keep our medicine in good condition and ensure the milk remains cool. In fact, it is vital for use in the pharmaceutical industry, brewery industry as well as meat and poultry. It has a long life span, has low operating sound, and is also energy efficient. They are safe to use, occupy less indoor space and do not make use of any toxic chemicals. It is advisable to purchase an air-cooled chiller system after performing proper research and from firms that are highly experienced and offer a guarantee of service. Some of the other factors to look out for include availability of service and affordability.
