Air Conditioning (Architecture)

Thinking Space is a series of short position papers on key terms and concepts for literary geography. Cumulatively, these accessible and wide-ranging pieces will explore the scope, parameters, and critical vocabulary of the field, clarifying important issues and stimulating discussion and debate.

Over the coming two decades Asia will be the main driver of a 40% increase in global energy consumption. Ambitions for a more sustainable future in the region are severely compromised by the widespread and rapid take-up of energy-intensive methods for cooling the built environment. For the majority of Asia’s countries buildings account for more than 50% of all national greenhouse gas emissions. With around half that energy consumption typically associated with cooling or heating interior spaces, national carbon footprints have increased dramatically in recent decades through the introduction of electronic airconditioning.
This paper argues such trends are unsustainable and low-carbon alternatives for environmental comfort are required urgently. It traces shifts in how air has been ‘materially imagined’ over the last century or so in Asia and how this bears upon the future of sustainable urbanism. Air-conditioning is seen as pivotal to transformations in urban design and living, such that two phases of modernity are identified: preconditioned and conditioned. By foregrounding the need for low-carbon alternatives, the paper advocates for an alternative, low-carbon regime of thermal governance.

Now days, global warming is one of the serious concern for environment to get protected from it every one is taking help of technology by the means of different types of refrigeration system for comfort food process, medicines, blood storage, humidity control, etc. use of refrigeration system not totally green or ineffective environment, if we can use proper eco-friendly refrigerant in refrigeration system and make number of refrigeration system less. Then it is not long way to be resolve global warming issue. In India middle class and poor families cannot afford all types of Refrigeration system like as AC, Refrigerator, Air cooler, etc. Generally they purchase only Air cooler. To solve this we can integrate Refrigeration system of AC, refrigerator and Air cooler in one product. So, that it cans multiplication and can we say as multifunctional Refrigeration system. This type’s product various components are used like as compressor, condenser, capillary tube, evaporator, motor, fan, etc

Craving for higher comfort and rise in living standards in various societies have led to higher demand for air conditioning. Energy consumption is related with climate change. Desiccant based air dehumidification systems can run with waste heat or renewable source of energy. Liquid desiccant (LD) based air conditioning systems are many times conceived as complicated and costly. A novel but simple internally cooled LDAD system is developed, integrated and tested in this work. Outdoor air was passed through the coil, thus making it essentially a study of fresh air enthalpy removal. Temperature range of 14 to 22oC was used for cooling water, which can be catered by a single stage vapour absorption refrigeration system on lower side or cooling tower on the higher side. The cooling capacity of the system increased up to 54%, compared to conventional chilled water coil. Latent heat fraction removed was also higher, showing usefulness of the system for higher latent load applications. Higher air velocity was found to give higher cooling capacity, while moisture removal per kg of air and effectiveness were higher at lower air velocities.
