HVAC Variable Refrigerant Flow Systems
Variable refrigerant flow systems with heat recovery (VRF-HR) capability can operate simultaneously in heating and/or cooling mode, enabling heat to be used rather than rejected as it would be in traditional heat pump systems. VRF-HR systems are equipped with enhanced features like inverter drives, pulse modulating electronic expansion

HVAC Variable Refrigerant Flow Systems
www.seedengr.comVRV/VRF systems can be used for cooling only, heat pumping or heat recovery. On heat pump models there are two basic types of VRF system: heat pump systems and energy-recovery. VRF heat pump systems VRF heat pump systems permit heating or cooling in all of the indoor units but NOT simultaneous heating and cooling.
Methods of Calculating Minimum Fresh Air Requirements
www.seedengr.comIf the occupancy of the building is known to be higher than the number calculated per floor area, then this number must be used to determine the minimum rate. Example: If five people were known to be using the computer room on a regular basis, the ventilation rate would be: Quantity of air (L/s) = Known occupancy rate x Rate/person (L/s) Solution:

www.pentair.comCirculation systems operate under high pressure. When any part of the circulating system (i.e. locking ring, pump, filter, valves, etc.) is serviced, air can enter the system and become pressurized. Pressurized air can cause the pump housing cover, filter lid, and valves to violently separate which can result in severe personal injury or death.
