Air Conditioning My Florida Home Energy. Credit This resource is a revised version of the fact sheet UFIFAS Energy Efficient Homes Air Conditioning EDIS FCS3. Wendell A. Porter, Craig Miller, and Hyun Jeong Lee2. Quick Facts. Heating, ventilation, and air conditioning can account for more than 4. For every degree setting below 7. F, you can spend up to 8 more in cooling costs. The average cost of electricity in Florida is 1. Wh EIA, 2. 01. 5. Upgrading from a 1. SEER to a 1. 4 SEER system can reduce your air conditioning costs by over 2. Terms to Help Get You Started. Air handler The indoor unit that moves the air through the heatingcooling system. BTU k. Wh British Thermal Unit kilowatt hours. Cooling load Load calculation Measurements that calculate what size system is appropriate for a particular structure given its square footage, ductwork analysis, insulation, windows, etc. Condenser The outdoor unit that keeps the refrigerant cool. Heat Pump An air conditioner equipped with a valve that lets it switch between cooling mode and heating modeHVAC Heating, Ventilation, and Air Conditioning equipment. SEER A measure of efficiency for air conditioning units the higher the SEER number, the more energy efficient the unit is in cooling the air. SHR A measure of efficiency for the ability of air conditioning systems to remove moisture or humidity the higher the SHR number, the less capable the system is in removing humidity. Supply Return Supply registers and ducts bring conditioned air in return registers and ducts draw air out to be reconditioned. Ton A measurement of size used to determine cooling capacity. Ventilation The natural or mechanical process of supplying conditioned or unconditioned air to, or removing such air from, any space. Why should I be concerned about the efficiency of my air conditioning system The largest consumer of energy in the typical Florida home is the heating, ventilation and air conditioning HVAC system, which can account for more than 4. Download Emergency 4 Portuguese Model more. A heat pump is an air conditioner in which the refrigeration cycle can be reversed, producing heating instead of cooling in the indoor environment.

Energy use by your HVAC system is affected by many factors such as insulation levels, system efficiency, shading on the home, quality and sealing of the windows and doors, design and integrity of the duct system, and, of course, how the system is used. Because of the heat and humidity, most Florida residents today rely on air conditioning systems to maintain not only reasonable comfort levels, but lower humidity levels as well. The size, efficiency, and placement of an air conditioning system, therefore, are all important. Equally critical is the air conditioning contractor selected, particularly because the operating efficiency of a system relies on proper installation to achieve its performance rating. A skilled air conditioning contractors keys to obtaining the designed efficiency of a system in the field include proper sizing of the system for the specific cooling load of the home selection and proper installation of thermostats or controls proper installation and commissioning of the system and, if required, a duct system designed to deliver the correct amount of conditioned air to each space within the building and sealing and insulating all ductwork.

How Does Air Conditioner Work Pdf' title='How Does Air Conditioner Work Pdf' />Sizing the air conditioner close to the actual load cooling requirement provides better humidity control and typically results in energy savings when compared to an oversized air conditioner with the same performance characteristics. Better humidity control results from a higher percentage of run time during which the coil is operating at its coldest temperature allowing more condensate to form and flow out of the system, while energy savings result from less start and stop operation and higher comfort levels due to better humidity control. Reducing the number of cycles may also result in longer equipment life. However, close sizing also comes with requirements. Since there should not be large excess capacity on the hottest days, the system must be properly maintainedmost importantly, keep it clean. Also, energy efficient features of the house that reduce air conditioning load such as proper sealing of ductwork, windows, insulation and sealing against infiltration must actually be done and done correctly.

Sizing is important. How Does Acupuncture Work For Weight Loss Dr Dre Detoxification 2009 How Does Acupuncture Work For Weight Loss Juice Detox Recipes Dr Oz Detox Water With Lemons And. To assure proper sizing, the load must be calculatednot just estimated based on square feet. Load calculations are based on the exact area, orientation, insulation levels, type of construction for each component of the building envelope, as well as the heat given off by the lights, people, and equipment inside the building, etc. The standard for residential air conditioning sizing is ACCA Manual J or a method based upon Manual J. ACCA stands for Air Conditioning Contractors of America. China Mobile Samsung Galaxy S3 Apps Free Download on this page. Make sure your contractor conducts comprehensive load calculations before accepting a bid. Central air conditioner and heat pump capacity is generally referred to in terms of tons. A ton of air conditioning is equal to 1. British Thermal Units BTUs per hour. What exactly is SEER The cooling efficiency of a heat pump or an air conditioning system is rated by the Seasonal Energy Efficiency Ratio SEER. The SEER is defined as a ratio of the average amount of cooling per unit of electricity used. The amended Federal Standard on residential air conditioners specifies that central air conditioners and central air conditioning heat pumps manufactured after January 1, 2. SEER for split system heat pumps. Efficiencies of some systems can be as high as SEER 2. It is important to understand that even though the SEER may be high, if the system is inefficient for example, leaky ductwork or oversized, you will not receive the full value of the efficiency as the air distribution system is not used to determine the SEER rating. So a high SEER system will also take care of the humidity in my house, right Not necessarily. You also need to consider the Sensible Heat Ratio SHR, which describes the moisture removal capability of air conditioning systems. A SHR on HVAC equipment of 0. It is critical that the HVAC contractor accurately estimate the humidity load also referred to as latent load. Outdoor air, coming in through poorly sealed windows and doors, open fireplace dampers, and bath and kitchen vents, causes most of the moisture load in your home. Even the simple act of opening and closing exterior doors adds humidity to your home. In addition, plants, bathing, cooking, cleaning, combustion, standing water in commodes and drains, and even breathing add to indoor humidity. A proper Manual J load calculation yields both the latent moisture load and the temperature based or sensible load. Typical dehumidification is performed by systems that use the same basic mechanics as air conditioners, and often air conditioners alone dehumidify the space. To keep humidity within comfort ranges, the buildings thermostats should have humidity sensors. If they do not, you can specify separate systems that can control humidity separately from the HVAC system. However, both comfort and energy efficiency will be better when humidity control is integrated with temperature control. Mechanical dehumidification is not the most energy effective means of dehumidifying, but it is the most common because it uses standard technologies. Mechanical dehumidifiers over cool incoming air below the dew point the point where it can no longer hold all the water vapor that was in solution. As a result, the water condenses on the cooling coils.
