Cooling Facts and Statistics

Below are some air conditioning facts, trends, and statistics you should know.

First Air Conditioner

Willis Haviland Carrier invented the first electrical air conditioning system in 1902.  Carrier’s invention aimed to control humidity in a printing plant to enhance the quality of the paper.

Following Carrier’s invention, air conditioning found applications in various industries, such as textile mills, food processing plants, and manufacturing facilities. Today, air conditioners are a common sight in homes, offices, and vehicles worldwide.

Global Air Conditioner Market

The global air conditioner market is expected to generate a revenue of US$67.32 billion in 2024. This market is projected to experience an annual growth rate of 6.42% CAGR between 2024 and 2028. The Air Conditioners market volume is expected to grow by 5% in 2025 and reach 142.3 million units by 2028.

The air conditioning (AC) sector is expected to grow substantially due to increasing global temperatures and humidity levels. The soaring temperatures are especially driving air conditioning demand in the UAE. Additionally, more people are perceiving air conditioners as essential utility items rather than luxury products.

Electricity Consumption

Air conditioning units account for a significant portion of energy consumption, contributing to 10% of global electricity use. Using more energy-efficient air conditioners can help you reduce cooling energy demand by 45%.
Manufacturers can use this as an opportunity to produce more energy-efficient air conditioners, while suppliers could make more sales by investing in energy-efficient cooling solutions.

Chiller Market

The worldwide chiller market is anticipated to register a CAGR of 4.2% between 2022 and 2027. The construction of new commercial buildings, urbanization, and the modernization of healthcare infrastructure are driving this market growth.

Furthermore, the rising number of chemical plants, a significant consumer of chiller systems, is expected to contribute to the increased demand for chiller systems throughout the forecast period. As the chiller market grows, it presents opportunities for chiller manufacturers and suppliers to produce, distribute, and sell more units.

Commercial Refrigeration Market

In 2023, the global commercial refrigeration equipment market size reached USD 40.82 billion. It is projected to grow at a compound annual growth rate (CAGR) of 5.2% from 2023 to 2030. The main drivers fueling this growth are technological advancements and the increasing demand for cold storage.

The rapid growth of the hospitality and tourism industry, coupled with the increasing inclination of end-consumers towards takeaway meals, is also anticipated to propel market expansion throughout the forecast period.

The rising demand for cold storage in hospitality and tourism presents an opportunity for both manufacturers and suppliers to produce and sell specialized cold storage equipment tailored to specific industry requirements.


Let’s look at some interesting heating statistics that could impact you.

Heat Exchanger Market

The heat exchanger market size was estimated at 17.73 billion in 2022 and is projected to grow at a CAGR of 11.1% to reach 24.76 billion in 2029. Industrialization is the major driving factor behind this market growth.

The increasing demand for heat transfer equipment for process cooling, condensation, and heat recovery is another fueling factor behind this market growth. This market growth provides an opportunity for manufacturers and suppliers to develop and distribute more heat exchangers that cater to industrial needs.


Ventilation is integral to maintaining indoor air quality and ensuring a healthy and comfortable living or working environment. Here are some ventilation statistics that emphasize its importance and impact on your overall well-being.

Commercial Ventilation Market Size

The global commercial ventilation systems market has been experiencing steady growth due to increasing awareness of indoor air quality and energy efficiency.

According to a recent report, the global ventilation and air quality control systems market is projected to reach USD 17.6 billion by 2025, with a CAGR of 5.5% during the forecast period (2020-2025).

The primary drivers of the market include heightened consumer awareness, stringent air quality control regulations, and an increasing awareness among the general public to mitigate health risks.

The UAE, in particular has been a hub for construction and infrastructure development, contributing to the growth of the commercial ventilation systems market. The UAE government has been actively promoting sustainable construction practices.

Green building standards, such as the Estidama Pearl Rating System in Abu Dhabi and LEED (Leadership in Energy and Environmental Design), have influenced the adoption of energy-efficient ventilation systems in commercial buildings.
