An evaporative cooler is technically a very simple machine with few working parts, comprising of a water tank, pump system, cooling pads, and fan system. It uses very little electricity and is considered environmentally friendly.
Air conditioners are the most popular and well-known air-cooling machines that control the temperature in a room through the process of refrigeration. The operating principle of an air conditioner is far more complicated than that of evaporative coolers as they use refrigerant gas. An air conditioner, regardless of the size, is comprised of an indoor unit and an outdoor unit, (unless it is portable) and both work together to maintain a desirable temperature. Some air conditioners can also heat a space.
Evaporative coolers and air conditioners have their advantages and disadvantages. Evaporative coolers are affordable, very easy to setup, relatively inexpensive to run, ensure steady supply of fresh air, and help filter the air. Some are also portable, and they can work efficiently in large, open spaces. The only major disadvantage of air coolers is that they do not work efficiently in humid climates.
Air conditioners are known for their efficiency in all weather conditions. They also have highly effective filtration systems. There are several disadvantages associated with the use of air conditioners, including being relatively expensive, having high running costs, and being more harmful to the environment. Air conditioners also work efficiently only in closed and confined spaces.
Depending on the climatic condition of your workplace, an evaporative cooler may be the best solution. Unless you work in a highly humid environment, evaporative coolers can efficiently keep your workplace cool without running up your utility bill. In addition to the economic benefits, they offer peace of mind since they are healthier for humans and the environment.
