The industry which produces air conditioning and cooling equipment is developing at fast paces. The units which are manufactured feature greater efficiency and more effective design. But it is not enough to rely on cutting edge technology only. There are a lot of efforts which are dedicated to the improvement of air conditioning systems control and their safety, by means of new technologies, to increase operating efficiency of these systems in commercial buildings.
For the purpose, companies are evaluating the total of the mixture of components, as well as the knowledge on the application, and also the service that is needed to help commercial owners to meet the needs for air conditioning in their premises and buildings and achieve cost effectiveness.
The effectiveness of commercial air conditioning units is expressed in the quietness and energy efficiency as they prove their performance in periods of seamless service in the modern tough climatic conditions which would not be endured without the efficiency of modern conditioning systems. These systems are developed to suit the needs of large scale buildings such as shopping centres, hotels, motels, and a number of other commercial sites. Modern systems feature options such as two pipe technology units which can simultaneously perform the functions of heating and cooling. Systems which comprise inverter as well as non inverter models are cost effective solutions which are increasingly common.
Seasonal efficiency is increasingly more important when considering the efficiency of commercial systems for air conditioning. It is a new way which can help to measure the energy efficiency of such systems, and it has the advantage of providing more realistic estimates and indications of the overall efficiency of a given system and what environmental impact it has. There are minimum eco design requirements which are abided by on part of manufacturers, so that they can feature systems which are environment friendly as well as efficient.
The terms used with respect to efficiency include nominal efficiency and seasonal efficiency. Nominal efficiency indicates the efficiency of commercial air conditioners when they operate at full loading and in nominal conditions, but that is not often achieved by such systems. The second indication, that of seasonal efficiency, has been developed to enable the obtaining of better measurements of the real energy efficiency of systems for air conditioning in commercial buildings. The seasonal efficiency is estimated as the efficiency of a system for air conditioning when it operates for the whole season, whether used for cooling or for heating purposes.
With the introduction of seasonal efficiency, there is the new demand for a novel rating system which has to be used by manufacturers of heating and cooling equipment. The new rating system includes the SEER, or Seasonal Energy Efficiency Ratio, with respect to cooling, and SCOP, or Seasonal Coefficient of Performance, with respect to heating.
The seasonal energy efficiency ratio is achieved by considering a number of factors which are examined as a combination to help gain more realistic indications of the efficiency of systems in real life conditions, including the following: the energy performance of the system in different climatic zones, the efficiency which is established at partial loading and at full loading, the energy consumption in both auxiliary mode and in standby mode, and the different requirements for loading in the course of the seasons.
