When I started my HVAC career in 1997, our DX compressor options in packaged rooftop units were limited. On/off compressors, two-stage, and hot gas bypass, if my memory serves. None of these worked well to control temperature and humidity over all load conditions, especially for high-content OA applications. Today, we are lucky to have digital compressors and variable-speed compressors. The common question is, which compressor should I use and why? Well, this informative guide by AAON answers those questions and more. This compressor technologies guide gives an overview of the benefits and costs of different compressor configurations and the efficiencies possible with varying configurations of rooftop units. AAON recognizes many reasons for choosing a specific compressor technology and offers many options to meet the needs of a particular application. This PDF guide has helped me understand the different options, and I hope you find it useful, too! #rooftopunits #hvac #aaon

5 Major VRF Installation Problems with troubleshooting 👇 #vrf #troubleshooting #hvac #hvacinstallation #hvacmaintenance

Testing & Commissioning of VAV Testing and commissioning (T&C) of Variable Air Volume (VAV) systems are crucial steps in ensuring that the HVAC system operates efficiently and meets design specifications. VAV systems regulate the airflow to different zones or spaces based on the current demand, providing energy savings and improving occupant comfort. Proper T&C ensures the system performs as intended. #vav #hvac #mep #bms #damper #actuator Daikin Comfort

No matter the season, Heat Recovery Heat Pump VRF simultaneously cools and heats different zones within a building. To accomplish this energy-saving operation, the same indoor unit that had low pressure refrigerant running through it for cooling will now have high pressure refrigerant for heating through the direction of the distributor box. The same can be said for the entire system. Executing proper pressure testing when commissioning or after major replacements, is crucial for VRF system performance. Most manufacturers recommend pressure testing the whole system up to 550 psi (Mitsubishi Electric Trane US recommends 600 psi) with a minimum of a 24-hour hold. Encore Mechanical ensures that our technicians stay on-top of the technical requirements of VRF manufacturers so that your occupants remain comfortable.  #vrf #vrfhvac #commercialhvac #vrfsystems #vrfexperts #vrfinsights #VariableRefrigerantFlow #buildingperformance
