Differences Between Air Conditioning And Climate Control Systems

by Josh Biggs in Tech on 22nd October 2020

The options for commercial air conditioning are increasingly varied and diverse, so we can adapt the equipment we want to install to the needs of the building. In this article, we will talk about the differences between three air conditioning and climate control options. 

We will start by defining what air conditioning is.

Air conditioning

The operating principle of air conditioning involves using refrigerant gases in a pipe circuit, to extract heat from the air in a room and, therefore, lower the temperature. This heat is expelled through the cooling circuit to the outside. In the commercial sphere, the most normal thing is to work with split units that work by zones, thus managing to refresh the air within the building.

Here is a review of some of the implications of installing a commercial air conditioning system.

Conventional split air conditioning system

  • This system works well in any environment, even with high temperatures and high humidity. This is an important advantage over the evaporative cooler, which is not efficient in climates where humidity is too high.
  • Can be used in an unventilated space, also works very well if the doors and windows are closed. The air conditioner adds humidity to the zone so it needs some ventilation to eliminate that excess humidity.
  • It allows good control of the temperature of the zone in which it is installed.
  • The appliances installed have filters for mites, dust, or bacteria. There is even split equipment options with antiviral ultraviolet filters.

Evaporative air conditioning

The evaporative air conditioner is a device that cools the air through evaporation. In evaporative coolers, water circulates from a reservoir to a moisture-wicking cooling pad. The outside air is then circulated through the wet pad by a fan. 

The evaporation that occurs in the pad releases heat by cooling the air that passes through it, ultimately cooling the air through evaporation. 

The most important thing for efficient evaporative cooling is that the system is well dimensioned. There are systems that require installation and also portable compact equipment that can cool an enclosed space.

  • The evaporative air conditioner ventilates and humidifies the environment that is too dry in the case that it is a system designed to take air from outside and not a compact indoor system.
  • It does not use refrigerant gases, so it can be considered more ecologically friendly.
  • It does not consume as much energy as a conventional air conditioning system.
  • The portability of some equipment allows it to be moved to other zones in the building.
  • It is cheaper than conventional air conditioning and its installation is very simple.
  • It does not work in environments with high humidity, since the environment is saturated and the equipment cannot evaporate enough and release heat.
  • They are louder than normal air conditioners.

Reversible heat pumps

As mentioned, an air conditioning system should provide cooling or heating when needed. Reversible heat pump systems already work with this type of technology, being able to cover the cooling and heating needs of the whole year. 

The heat pump is a system that takes advantage of the heat that the air stores at room temperature, and, through an efficient compressor, converts it into heat usable in the building. In the same way, thanks to its reversible system, in summer it will extract heat from the building and dissipate it outside.

Some features of reversible heat pumps:

  • Powered by electricity, and so efficient that they are already considered a type of renewable energy.
  • Require installation with an outdoor unit, and it is not always possible to install it on roofs.
  • Need a refrigerant circuit.
  • They allow hybrid energy supply systems, making it an even more sustainable technology.
  • Installations can be done with other systems that improve air quality, such as filters, or systems that improve energy efficiency such as air recirculation or heat recovery systems.

So these are three common commercial air conditioning systems that might meet your cooling and heating requirements. The best thing is always to consult with a specialist installer who will resolve any doubts and advise on the best system for your particular case.
