How is the capacity of chiller required by different industries and places determined?
When choosing a chiller is one of the factors that determine its capacity. This means that the buyer must choose the appropriate chiller or capacity according to his needs and purpose. Factors affecting the required chiller capacity are:
Climate and geographical conditions
For example, hot and humid climates with hot and dry climates with temperate climates each require a chiller with a different capacity and not all of them can be served with the same chiller.
Air circulation
This factor can actually be considered a disruptor or enhancer. This means that opening and closing the door or the presence of vents and windows can weaken or help a percentage of the chiller effort.
The intensity of sunlight
As the environment becomes sunnier, the need for higher capacity will increase.
The amount of traffic and traffic in the building space
Which acts almost similar to air circulation but in its negative aspect. This means that the more traffic in an environment, the more cooling the air needs and therefore the more capacity the chiller has.
Population density at the site
The number of people presents in the environment simultaneously in a certain interval, which is directly related to the capacity of the chiller.
Project scale and size
The intensity and scope of industrial refrigeration projects, which is clearly directly related to the capacity of the chiller
The height of the environment also affects the capacity of the chiller you need!
The height of the ceiling and the area of the environment, which, by increasing, leads to an increase in the volume of the desired space for cooling.
And of course the presence of other air conditioners and heating or cooling devices, which act as a contributing factor or attenuation of the chiller.
Impact of final cost on determining the capacity of required chillers
It is not possible to say exactly which chiller is the most expensive and which one is cheaper than the others. This is because in addition to the components of the chiller, how to install and maintain it is also calculated at the cost of purchase. A chiller made of simpler, less expensive components may be more expensive to install.
For example, air-cooled chillers have low installation and maintenance costs because they are simple to build and do not require a cooling tower, unlike water-cooled chillers, but their own air-cooled condenser is expensive, so the initial cost of choosing the right chiller Raises. Or as another example, absorption chillers have a higher purchase price and a higher initial cost than compression chillers, but at the same time, they can be equivalent to their other competitors, the compression chillers. Because this chiller does not have a high cost of maintenance and supply of raw materials, but compression chillers are more expensive for their owners both in terms of maintenance and service and in terms of providing electronic energy.
Also, depending on the geographical conditions of the region, one place can consider fossil energy as cheap fuel and another place can rely on a large water source to use water to cool its chiller condenser on the agenda.
What are the costs of chiller maintenance and repairs?
The best way to repair and maintain a chiller is to reduce its service costs and, of course, reduce the risks and hazards of malfunctioning chiller and disrupt work by preparing a daily maintenance checklist. Daily maintenance of the chiller includes different items and varies depending on the size of the facility, capacity, number of chillers and of course the use of the building. For example, industrial or modular and industrial chillers require more daily care and service than home chillers. Also, home chillers are installed for the residents of an apartment or house who may have little knowledge of the device. Therefore, they should seek the help of a specialist to repair and service the chiller. Examples of determining criteria for the cost of chiller repair can be:
- Number of compressors
- Number of cycles (there are two cycles by default inside the chiller: one between the evaporator and the cooling space, the other between the evaporator and the expansion valve; which is considered the key cycle of the chiller)
- Number of cooling towers (for cold water chillers)

In addition, as mentioned, your type of chiller can be cost-effective to maintain. For example, since a cold water chiller requires a cooling tower, tower maintenance should also be on the agenda. It should also not be overlooked that the higher the capacity of the required chiller, the higher the maintenance cost.
Finally, it should be noted that in addition to all this, there are things that are done to maintain the health of the chiller and reduce the risk of sudden failure of the chiller. In this way, there is no need to bear the heavy costs of maintaining or replacing the chiller. Chiller maintenance items are as follows:
- Use a water purifier to prevent fouling
- Staining and paying attention to the smallest stains and leaks
- Cleaning of internal pipes for efficient heat transfer between pipes
- Regular control of the amount of oil and refrigerant in the system
