In terms of general characteristics, air-cooled chillers are less efficient than water-cooled chillers. However, in some cases, cool air chillers are preferred.

Now the question arises that when choosing and buying a cool air chiller, what points should be considered ?!

Criteria to consider when choosing a cool air chiller!

1- Minimum chiller capacity

When choosing a cool air chiller, the characteristics of the area used and the capacity of the device used are taken into account. Where the area used is very cold and the temperature difference between day and night is very large, cool air chillers are preferred. However, in such cases, it should be considered whether to use devices with a minimum capacity or not. If there are low capacity appliances, it makes sense to prefer air-cooled chillers.

2- The effect of height on the performance of the cool air chiller

The height factor is the next thing you should pay attention to when buying a cool air chiller. In cool air devices, the capacity decreases with increasing altitude. So you have to consider this factor thoroughly.

3- Chiller control type

If you are going to choose a cool air chiller, you should also consider how to control the chiller. Because devices that are easily controlled promise more efficient work and performance.

4- Resistance to air temperature

In cold air devices, the remaining capacity of the device is reduced by 1% per 1 ° C. This is an important point that will greatly affect your choice. At the same time, this change also affects the compressor and increases the power drawn by the compressor by 1%.

5- Selecting a cool air chiller based on the pressure applied to the device

It is necessary to protect the devices as much as possible against high pressure, whether the air is cool or the water is cold. For this purpose, the amount of condenser air flow must be high. At the same time, low and medium pressure refrigerants should be preferred.

6- Low evaporator pressure drop

Again, in the group of air-cooled chillers, the values ​​of evaporator pressure drop should not exceed 60 kPa as much as possible, and in the group that prefers the lowest steam pressure drop as much as possible.

7- Physical size of the chiller

The size of the chiller plays an important role at this stage. If you have a small business, keep in mind that chillers are often smaller in size than cold water chillers. In such cases, cool air chillers are generally preferred because they take up little space.

8- The amount of noise caused by the activity of the device

The issue of cool air chiller noise should also be considered. In places where noise is important, groups whose sound pressure does not exceed 75dBA at a distance of 5 meters in open space should be selected, and groups with low noise levels should be preferred.

9- Special permits for cool air chillers to choose from in special places

Sheet metal parts and pieces Groups that are installed on the beach and exposed to the atmosphere of salinity and corrosion must have the relevant certificates to protect the external and internal components of the chiller. For example, if possible, a copper tube or copper fin should be selected.

10- Number of compressors

The number of compressors of the selected chiller group and the number of refrigerant circuits must be written in the specifications.

When you consider the points to consider when buying a cool air chiller, you get cool air chiller systems that you can use for years with the same functionality and get maximum performance.

Choosing the right air-cooled chiller is crucial for ensuring optimal performance and energy efficiency in various applications, from industrial processes to HVAC systems. In this guide, we will explore the key factors to consider when selecting an air-cooled chiller, answer common questions, and provide practical tips for making an informed decision.

Understanding Air-Cooled Chillers

Air-cooled chillers are refrigeration systems that use air to dissipate heat from the refrigerant. Unlike water-cooled chillers, they do not require a cooling tower, making them easier to install and maintain. These chillers are ideal for applications where water resources are limited or where water usage needs to be minimized.

3. Ambient Temperature: Consider the ambient temperature conditions where the chiller will be installed. Air-cooled chillers need to dissipate heat into the surrounding air, so their performance can be affected by high ambient temperatures. Ensure the chiller is rated for the maximum ambient temperature it will encounter.

4. Noise Levels: Evaluate the noise levels of the chiller, especially if it will be installed in or near occupied spaces. Look for models with noise reduction features or sound enclosures to minimize disruption.

5. Footprint and Space Requirements: Assess the available space for the chiller installation. Air-cooled chillers come in various sizes, so ensure the unit fits within the designated area and allows for proper airflow and maintenance access.

6. Reliability and Maintenance: Choose a chiller from a reputable manufacturer known for reliability and durability. Consider the ease of maintenance and availability of spare parts to ensure the chiller operates smoothly over its lifespan.

7. Environmental Impact: Look for chillers that use environmentally friendly refrigerants with low Global Warming Potential (GWP) and Ozone Depletion Potential (ODP). This helps minimize the environmental impact and ensures compliance with regulations.
