VRV Multi-Split Type Air Conditioners. The Daikin VRV system is a multi-split type air conditioner for commercial buildings that uses variable refrigerant flow control developed by Daikin to provide customers with the ability to maintain individual zone control in each room and floor of a building.hen Daikin launched the VRV air conditioning system in 1982, it introduced the worldâs first use of variable refrigerant flow control. This technology circulates only the minimum amount of refrigerant needed at any one time and enables individual climate control of air conditioning zones.
    PCV is an acronym for Positive Crankcase Ventilation. This valve is needed to relieve the pressure built up in the crankcase that is created by the heating of the air inside the engine. If this valve were not present and the pressure went unchecked, it would blow out the seals and gaskets inside your engine.    PCV stands for Positive Crankcase Ventilation.This replaceable valve replaced the vent pipe on the engine, this got rid of the fumes and or pressure that builds up in the crankcase, nowadays the crankcase does not vent into the environment. Answer   A PCV valve is a valve (or fixed orifice metering device) which adjusts airflow through the PCV system to allow PCV operation without adversely affection â¦ fuel metering. The PCV system moves air from the air cleaner through the crankcase, then into the engine intake.
