Efficient air conditioning systems, in conjunction with other technologies as well, can improve local and regional air quality, particularly in large cities, contributing to improved public health (e.g., increased life expectancy, reduced emergency room visits, reduced asthma attacks, fewer lost working days) and avoidance of structural damage to buildings and public works (IPCC 2007). Every third commercial building in India has a Blue Star product installed inside. The following are the most common types of cooling applications: 1. It also adds or removes moisture to and from the air as needed. 3.Air from the home's ductwork is blown over the heat exchanger, warming the air. Year-round air-conditioning… Packaged air conditioners are similar to window air conditioners since all the components are housed in one single unit. That is, they consist of a ‘hot’ side, or the condensing unit—including the condensing coil, the compressor and the fan—which is situated outside your home, and a ‘cold’ side that is located inside your home. AIR CONDITIONING SYSTEM (HEATING AND COOLING PROCESS) Author: Muhammad Sohaib Alam Contents Page number Abstract 1 Objective 1 Theory 1 Apparatus 5 Procedure 5 Results 6 The experiment also enabled us to determine the heating and cooling power of the respective coils as well. For low and average cooling demands, it runs on low to save energy. Programmable thermostat – With a programmable thermostat, you can set your air conditioner and furnace to automatically run at previously selected energy saving temperatures when you’re away from home or in bed. Split or Packaged: Which is right for Your Home? January 1, 2015: The Montreal Protocol requires the U.S. to reduce its consumption of HCFCs by 90% below the U.S. baseline. To keep the central air conditioner working properly, regular maintenance is required. This cooled air becomes warmer as it circulates through the home; then it flows back to the central air conditioner through return ducts and registers. central air conditioning system includes both the cooling and heating of air and cleans the air as well as controls the moisture level. Consumers should be aware that dealers of systems that use substitute refrigerants should be schooled in installation and service techniques required for use of that substitute refrigerant. Air-cooled – These condensers are cooled by the surrounding air. This video describes the working principle of an Air Conditioner. This type of cooling system is used to cool the entire home, versus a window air conditioner that is used to cool a specific area or room of your home. In addition, R-22 is a greenhouse gas and the manufacture of R-22 results in a by-product (HFC-23) that contributes significantly to global warming. According to the purpose. The most common type of central air conditioning is the split system, which features a large, boxy condenser outside the home and a fan-and-coil system … Turning on the Air Conditioner, when the gas is a liquid, can cause the liquid to slug the compressor.”, (Think of throwing a bird into a jet engine), What you should know about Refrigerants when purchasing or repairing a Residential A/C System, http://www.epa.gov/ozone/title6/phaseout/22phaseout.html. They also can control humidity, air quality and airflow within your home. The outdoor unit contains the condenser coil, compressor, electrical components and a fan. Summer air conditioning system c.Year-Round Air Conditioning System 4. The high pressure and high temperature refrigerant then go to the condenser. It is the default choice for large commercial properties and most new homes are outfitted with this type of air conditioner as well. Installing a packaged system requires only outdoor work with no need to connect different pieces of equipment. a. Space requirements – If the open areas (attic and/or basement) in your home are limited to conveniently accommodate an A/C indoor unit, a packaged system (mini split) may be a better option. SEER is a ratio of a system’s total cooling capacity throughout the cooling season over the amount of electricity it uses in that time. For the next 10 years or more, R-22 should continue to be available for all systems that require R-22 for servicing. http://msdssearch.dow.com/PublishedLiteratureDOWCOM/dh_040b/0901b8038040bc62.pdf?filepath=styrofoam/pdfs/noreg/179-07590.pdf&fromPage=GetDoc, alternatives to R-22 for household and light commercial air conditioning, Home Inspection Red Flags That Will Need…, Evaporator coils that change refrigerant from liquid to gas, A compressor that pressurizes refrigerant gas, Condenser coils that turn refrigerant gas into a liquid, Refrigerant lines that carry refrigerant between the coils, An expansion device that regulates refrigerant flowing to the evaporator. The refrigeration cycle continues again, providing a consistent method to keep you cool. 6. Quick Reference Guide for 2009 IECC Residential Energy Efficiency, Climate Zone 5 http://msdssearch.dow.com/PublishedLiteratureDOWCOM/dh_040b/0901b8038040bc62.pdf?filepath=styrofoam/pdfs/noreg/179-07590.pdf&fromPage=GetDoc. Hot, low-pressure refrigerant gas moves to the compressor, which increases the pressure and temperature of the gas.
