Now customize the name of a clipboard to store your clips. For this reason, all air conditioners use the same cycle of compression, condensation, expansion, and evaporation in a closed circuit. The winter air conditioning uses a heat pump (refrigeration system operated in the reverse direction) and a humidifier. A difference is made between absolute humidity and relative humidity. Air conditioning   Air conditioning is the science which deals with the supply and maintaining desirable internal atmospheric condition irrespective of external condition. For an air conditioning system to operate with economy, the refrigerant must be used repeatedly. Solar Air Conditioning - Here, at Solar Green, we pride ourselves to be the renowned & the most trusted partner of green energy, providing a huge range of Solar powered products, for commercial as well as residential use. As with all air conditioning systems the principle remains the same whereby the heat is removed from one area and replaced with chilled dry air and the hot air is expelled, normally to the outside atmosphere. There have been four main refrigerants used in air conditioners over the years. Gases give off heat when changed from gas to liquid. Air conditioning also plays an important role in industry, agriculture and research. We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads. The book begins by developing the fundamental principles of air conditioning, followed by a description of equipment and systems. Comfort air conditioning deals with the air conditioning of residential … For air conditioning the relative humidity is more impor-tant. When this refrigerant is compressed, it becomes quite cold. … See our Privacy Policy and User Agreement for details.

Introduction and Basic Concepts of Refrigeration and Air Conditioning: First, let's understand a few things. See our User Agreement and Privacy Policy. Basic Concepts of Air Conditioning Prepared exclusively for COACH LEATHERWARE. The basic concept behind air conditioning is said to have been applied in ancient Egypt, where reeds were hung in windows and were moistened with trickling water. … The chiller is the section of the system where an exchange of heat occurred between the water that goes to the building and the evaporator. Heat is a form of energy. See our Privacy Policy and User Agreement for details. When you work around the refrigeration system - or any part of the HVAC system - remember these principles: • You are dealing with electricity, heat, pressures, and possibly toxic gases. As the compressor takes the most power in any air conditioning system, the change in the compressor technology has enabled better and more efficient air conditioner or heatpump to be deployed.  Air conditioning may be defined as simultaneous control of temperature, humidity, motion of air and purity of air within the enclosed space. The evaporation of water cooled the air blowing through the window. First of all understand basic geometry. Air conditioning theory. 1. Search Search. This process also made the air more humid, which can be beneficial in a dry desert climate. Learn more about Scribd Membership.
