| basic diagram of air conditioning system: Modeling and Control in Air-conditioning Systems Ye Yao, Yuebin Yu, 2016-10-01 This book investigates the latest modeling and control technologies in the context of air-conditioning systems. Firstly, it introduces the state-space method for developing dynamic models of all components in a central air-conditioning system. The models are primarily nonlinear and based on the fundamental principle of energy and mass conservation, and are transformed into state-space form through linearization. The book goes on to describe and discuss the state-space models with the help of graph theory and the structure-matrix theory. Subsequently, virtual sensor calibration and virtual sensing methods (which are very useful for real system control) are illustrated together with a case study. Model-based predictive control and state-space feedback control are applied to air-conditioning systems to yield better local control, while the air-side synergic control scheme and a global optimization strategy based on the decomposition-coordination method are developed so as to achieve energy conservation in the central air-conditioning system. Lastly, control strategies for VAV systems including total air volume control and trim & response static pressure control are investigated in practice. |

| basic diagram of air conditioning system: Concepts of HVAC Shivendra Nandan, Prakash Sharma, Inside an air conditioning system is a chemical refrigerant which is a chemical compound that easily changes states from liquid to vapor and back again. A common trade name for refrigerant which you may be familiar with is Freon.In addition to refrigerant, an air conditioning system requires a minimum of four components, the compressor, condenser, metering device, and evaporator.1) The CompressorThe compressor is the heart of the system. Just like your heart pumps blood through your body at a specific flow rate and pressure, the compressor pumps the refrigerant through the air conditioning system at a designed flow rate and pressure.When the refrigerant enters the compressor it is in a vapor state. It enters the compressor because it is literally being sucked into it. That is why the side of the compressor where refrigerant enters is called the suction side or low pressure side. As its’ name suggests the compressor compresses the vapor as it is being pumped through it. When a vapor is compressed both the pressure and temperature of that vapor increases. The vapor leaving the compressor is very hot. You will get burnt if you were to touch the copper refrigerant lines coming off of the compressor. In the above diagram the high pressure vapor refrigerant is represented by red dots.2) The CondenserThe high temperature refrigerant passes into a condenser coil. As the vapor refrigerant travels through the coil, air from a fan passes over the coil to cool the vapor refrigerant. As the vapor cools it condenses and becomes a liquid, this is referred to as a “change of state”. This “change of state” from vapor to liquid is essential. You may be somewhat familiar with a typical home system where the condensing unit sits outside. When operating you can place your hand over this unit and feel the warm air being blown out. Inside this condensing unit high temperature vapor refrigerant is entering into it, as the heat energy in the vapor is removed by blowing air across the condenser coil, the vapor changes to a liquid. You will soon see that the heat being blown from the condensing unit is the heat that used to be in your home. In the above diagram the liquid is represented by solid red.3) The Metering DeviceThe metering device controls the flow of the liquid refrigerant to the next component which is the evaporator. This is a dividing point between the high pressure and low pressure sides of the system. As this high pressure liquid is passing through the metering device and into the evaporator the pressure drops.4) The EvaporatorAfter leaving the metering device the refrigerant immediately enters a coil called the evaporator. This coil or evaporator has a fan blowing across it. As the refrigerant enters the coil at a lower pressure it begins to bubble and boil and “change state” back to a vapor. During this process of changing state, energy in the form of heat is being removed from the air passing over the coil and is being absorbed by the refrigerant. The heat that was in the air is transferred into the refrigerant. Since heat was removed from the air blowing over the evaporator coil, the air leaving the evaporator coil is cold. You see that an air conditioner makes cold air by having the heat that is in the air absorbed into the refrigerant.Now that heat from your computer room, office area etc. is in the refrigerant what do we do with it? The heated refrigerant is sucked into the compressor and pumped back to the condenser coil. Here in the condenser the heat that was earlier absorbed by the refrigerant in the evaporator section from the space we are cooling is released and removed. The process of the refrigerant “changing states” from vapor to liquid (releasing heat through the condenser) and from vapor to liquid (absorbing heat in the evaporator) is how an air conditioner works. |
