Introduction. The modern day definition of air conditioning was created in the early 2. Hermann Rietschel, Alfred Wolff, Stuart Cramer, and Willis Carrier. Cramer, a textile engineer in North Carolina, is credited with coining the phrase air conditioning in 1. In 1. 90. 8, G. B. Wilson developed the first holistic definition of what air conditioning encompasses. The Original Definition of Air Conditioning. To maintain a suitable degree of humidity in all seasons and in all parts of a building. To free the air from excessive humidity during certain seasons. To supply a constant and adequate supply of ventilation. Super Sonic Mugen Download. To efficiently wash and free the air from all micro organisms, effluvias, dust, soot, and other foreign bodies. To efficiently cool the air of the rooms during certain seasons. To either heat the rooms in winter or to help heat them. To combine all the above desiderata in an apparatus that will not be commercially prohibitive in first cost or cost of maintenanceSource Nagengast, B., 1. Early Twentieth Century Air Conditioning Engineering, ASHRAE Journal, March p. Though he did not actually invent air conditioning nor did he take the first documented scientific approach to applying it, Willis Carrier is credited with integrating the scientific method, engineering, and business of this developing technology and creating the industry we know today as air conditioning. Description. Todays HVAC R engineer, or mechanical engineer of record MER, continues to be a steward of the basic discipline issues identified by Mr. Wilson nearly 1. 00 years ago. Roles have expanded, though, to address more modern quality of life issues. ASHRAE offers the current vision of the MERs stewardship responsibilities to improve the quality of life by helping keep indoor environments comfortable and productive by helping to deliver healthy food to consumers and by helping to preserve the outdoor environment. As part of a holistic controlled environment design solution, the MER is responsible for addressing seven major processes. Mollier diagram Pro air treatment calculations.

Dehumidifyingthe removal of water vapor to maintain space or process moisture content. Cleaningthe process of removing particulate and bio contaminants from the conditioned space. Ventilatingthe process of providing suitable quantities of fresh outside air for maintaining air quality and building pressurization. Effectivenessthe process of achieving the desired thermal energy transfer, humidity control, filtration, and delivery of ventilation air to the breathing zone of the occupied space in accordance with required needs. It is important for the MER to be involved early in the project, even as early as the programming stage, so that mechanical system space issues and facility energy budgets can be evaluated and integrated into the design process before building construction elements, configurations, and orientations are finalized see also WBDG High Performance HVAC. A few critical issues that need to be considered early are Financial Focus Will the project be a code minimum type facility or will total ownership cost perspectives be considered that balance capital first costs against long term ownership and operating costsHVAC Peak Load Calculation Methods History and Comparisons by Bill Smith, president of Elite Software Copyright 2011 This article discusses both commercial and.

Carrier Hvac Calculation Software' title='Carrier Hvac Calculation Software' />Owner Sophistication The MER needs to understand the abilities of the owner and keep these in mind as mechanical system architecture issues are considered. The best of design solutions arent much good if operators do not understand how to correctly operate or control the equipment. Operations and Maintenance No matter what level of system complexity is applied, it is imperative that suitable space be made available for equipment without compromising performance or maintenance access. A good MER will understand the requirements published in equipment installation manuals and focus on providing prescribed minimum service and operating considerations in the planning of a facility layout. Before any equipment selections can be finalized, the MER will need to perform a thermal load calculation for the developing facility based on internal and external influencing factors. In many cases, this activity will be expanded to include analysis of comprehensive energy models. These models will foster dynamic integration opportunities whereby the design team and owner can evaluate the impacts of trade offs between facility construction elements, mechanical system alternatives, and available operating efficiencies. Load calculations can be utilized for any or all of the following design activities Defining the basic load dynamics. Evaluating solution alternatives via life cycle analysis. Optimizing system performance. Selecting final HVAC equipment. Establishing energy budgets for owners. Verification of proposed equipment performance. Commissioning Design Intent for seasonal comparison. The MER will be responsible for securingdeveloping the following fundamental information from the Owner and design team members Basic Load Calculations Establish summerwinter design weather conditions paying particularly close attention to regional weather issues and impact on humidificationdehumidification considerations. All elements of the building envelope must be identified so that thermal energy lossgain can be determined. Reference should be made to ASHRAE Standard 9. Orientation of walls and roofs need to be defined so that sun angle impacts can be evaluated. The composite construction of all walls, roofs, and floors needs to be defined so that thermal transfer calculations can be performed. This information will also be useful when a dew point analysis is performed on the envelope. Thermal mass and color of walls and roofs need to be defined so that thermal time lags and radiation absorption can be evaluated. Carrier Hvac Calculation Software' title='Carrier Hvac Calculation Software' />Fenestration U values and solar heat gain coefficients need to be defined. Externalinternal shading provisions need to be defined that may impact fenestration heat gain. Lighting. Lighting densities and ballast loss factors need to be mapped per individual space. Maximum densities are identified for individual space types in ASHRAE Standard 9. Opportunities to capture natural light Daylighting and apply occupancy sensing techniques to reduce light heat gain need to be explored. Basic internal sensible heat gain allowances for receptacle loads need to be established. Miscellaneous sensible and latent heat gain values need to be identified for special circumstances. People contributions. The total number of people and the occupancy usage profiles need to be established. The activity levels of people need to be identified. Ventilation. For a given space, the area factor and people factor ventilation rate components need to be calculated per ASHRAE Standard 6. Depending on HVAC system architecture employed, critical space calculations may need to be performed to adjust ventilation quantities to ensure adequate outside air is being provided to occupied spaces during all system fluctuations. Calculate all building exhaust requirements and compare to minimum required outside air ventilation rates. Elite Software Rhvac.

Powered by ACCA Manual D Ductwork Design Rhvac can help you in several ways on sizing ductwork. For those who do not want to enter complete details about a duct system, Rhvac Desktop can still suggest the number of registers needed for each room, the runout duct size leading to each register, and the initial size of the main trunk duct. Washington Tuition Reciprocity Program on this page. For example, if a family room is calculated to require 2. CFM, Rhvac will suggest two registers to deliver 1. CFM each. And if flex duct was specified, Rhvac will spin the ductulator for you and calculate using the equal friction method that each duct should be 6 in diameter. And if the project needed 1. CFM total, Rhvac knows that the first part of the main trunk has to carry that much air and it will calculate the main trunk size. Automatically, for every project, Rhvac Desktop will tell you runout duct sizes and the initial main trunk size. All you have to do is say what materials steel, ductboard, or flex duct are being used for trunk and runout ducts. You get lots of duct info with minimal input required.
