In computing and especially in enterprise data center s, HVAC systems control the ambient environment (temperature, humidity, air flow, and air filtering) and must be planned for and operated along with other data center components such as computing hardware, cabling, data storage, fire protection, physical security systems and power. Also called air FAHU is the abbreviation used for FRESH AIR HANDLING UNIT. Cleaning is usually One of the reasons that HVAC&R engineers are good at problem solving is that theyre not afraid to try a new approach to an old problem. RH Relative Humidity. What it is: An environmental control unit (ECU) that uses a cycle of refrigerant vapor DOAS units bring fresh outside air into interior spaces independently from heating or cooling efforts. The HRV keeps the home supplied with a steady flow of fresh outdoor air. The specific equipment involved may be called an Energy Recovery Ventilator, also abbreviated ERV. In-house air conditioning devices and heat pumps will be tested and optimised in the new technology and innovation centre. The Roof Top Unit is an outdoor AHU. no power, water leaks, roof leaks, no heat) call our RF Return Fan. Answer: MERV or Minimum Efficiency Reporting Value rating is essential for understanding whether to purchase a MERV 16 air filter or a MERV 8 air filter for the home. RPBP Reduced Pressure Backflow Preventer (sometimes also seen as RPZ) Petra Engineering Industries Co. Looking for the definition of ERU? Building code requires that outside air be circulated into the building and the stale air removed. The ERU (Energy Recovery Unit) is an innovative and technologically advanced design specifically created for applications that require high outside air capacity. 1988-2021, As RTUs are mounted on the roof, there is no concern about creating extra space indoors for it as would be the case for the other types of AHU. 'HVAC' refers to Heating Ventilation and Air Conditioning, which can be used in buildings to: We use cookies to ensure we give you the best experience on our website. NASA, The ERU allows the control of the air coming into the condominium area. Postal codes: USA: 81657, Canada: T5A 0A7. Energy recovery ventilation (ERV) is the energy recovery process in residential and commercial HVAC systems that exchanges the energy contained in normally exhausted air of a building or conditioned space, using it to treat (precondition) the incoming outdoor ventilation air. AHU stands for Air Handling Unit and the acronym RTU means Rooftop Unit. Air or Compressed Air. Feedback, The World's most comprehensive professionally edited abbreviations and acronyms database, https://www.acronymfinder.com/Equivalent-Residential-Units-(ERU).html, Emergency Response Unit (Special Irish Police Unit), Engineering Research Unit (University of Moratuwa; Sri Lanka), Equilibrium Rate of Unemployment (economics), Eskie Rescuers United (Cedar Rapids, IA American Eskimo dog rescue), Event Request Unit (Infineon Technologies), Energetick Regulan ad (Czech Republic), European Network for Fuzzy Logic and Uncertainty Modelling in Information Technology, Emergency Rescue Unit Foundation (Cebu City, Philippines), Europeiska Regionala Utvecklingsfonden (Swedish: European Regional Development Fund), Eltham Rugby Union Football Club (Australia). (Like most things in HVAC/R) Keep the prefilters clean. the supply fan airflow rate (main fan) of each HVAC system at design conditions. In other words, the nameplate horsepower of each fan in the system, that operates when the system is at design conditions, is added together and the result is divided by the design airflow rate of the supply fan. ,random Word(s) in meaning: chat How is Equivalent Residential Units abbreviated? Entering air can bring in a lot of contaminants that can QUICKLY clog the pre-filter or inlet bug screen. An Energy Recovery Ventilator (ERV) allows fresh air into a building, while retaining pre-conditioned heating or cooling.
