One important constraint during the design of the CHP system was to control the final temperature of this exhaust gas. This meant utilizing as much heat as required from the exhaust gas and subsequently bringing down the exit temperature. After running different iterations on temperature calculations, it was decided to divert 35% of the exhaust air to the heat exchanger while the remaining 65% is directed to go up the stack. This is achieved by using a diverter damper. In addition, diverting 35% of the gas relieves the problem of back pressure buildup at the end of the turbine. A diverter valve can also used at the inlet side of the heat exchanger which would direct the exhaust gas either to the heat exchanger or out of the bypass stack. This takes care of variable loads requirement. Inside the heat exchanger, exhaust gas enter the shell side 大 連海洋大學(xué) 2021 屆畢業(yè)設(shè)計(jì) 外文翻譯（英文） and heats up water running in the tubes which then goes to the absorption chiller. These chillers run on either steam or hot water. The absorption chiller donated to the University runs on hot water and supplies chilled water. A continuous water circuit is made to run through the chiller to take away heat from the heat input source and also from the chilled water. The chilled water from the absorption chiller is then transferred to the existing University chilling system unit or for another use. Thermally Activated Devices Thermally activated technologies (TATs) are devices that transform heat energy for useful purposed such as heating, cooling, humidity control etc. The monly used TATs in CHP systems are absorption chillers and desiccant dehumidifiers. Absorption chiller is a highly efficient technology that uses less energy than conventional chilling equipment, and also cools buildings without the use of ozonedepleting chlorofluorocarbons (CFCs). These chillers can be powered by natural gas, steam, or waste heat. Desiccant dehumidifiers are used in space conditioning by removing humidity. By dehumidifying the air, the chilling load on the AC equipment is reduced and the atmosphere bees much more fortable. Hot air ing from an airtoair heat exchanger removes water from the desiccant wheel thereby regenerating it for further dehumidification. This makes them useful in CHP systems as they utilize the waste heat. An absorption chiller is mechanical equipment that provides cooling to buildings through chilled water. The main underlying principle behind the working of an absorption chiller is that it uses heat energy as input, instead of mechanical energy. Though the idea of using heat energy to obtain chilled water seems to be highly paradoxical, the absorption chiller is a highly efficient technology and cost effective in facilities which have significant heating loads. Moreover, unlike electrical chillers, absorption chillers cool buildings without using ozonedepleting chlorofluorocarbons (CFCs). These chillers can be powered by natural gas, steam or waste heat. Absorption chiller systems are classified in the following two ways: 1. By the number of generators. i) Single effect chiller – this type of chiller, as the name suggests, uses one generator and the heat released during the absorption of the refrigerant back into the solution is rejected to the environment. ii) Double effect chiller – this chiller uses two generators paired with a single condenser, evaporator and absorber. Some of the heat released during the absorption process is used to generate more refrigerant vapor thereby increasing the chiller’s efficiency as more vapor is generated per unit heat or fuel input. A double effect chiller requires a higher temperature heat input to operate and therefore its use in CHP 大 連海洋大學(xué) 2021 屆畢業(yè)設(shè)計(jì) 外文翻譯（英文） systems is limited by the type of electrical generation equipment it can be used with. iii) Triple effect chiller – this has three generators and even higher efficiency than a double effect chiller. As they require even higher heat input temperatures, the material choice and the absorbent/refrigerant bination is limited. 2. By type of input: i) Indirectfired absorption chillers – they use steam, hot water, or hot gases from a boiler, turbine, engine generator or fuel cell as a primary power input. Indirectfired absorption chillers fit well into the CHP schemes where they increase the efficiency by utilizing the otherwise waste heat and producing chilled water from it. ii) Directfired absorption chillers – they contain burners which use fuel such as natural gas.
