VRV　system　is　a　more　effective　and　energy-saving　central　air-conditioning　system　in　office　buildings　due　to　its　variable　load　modes　and　flexibility　in　adjusting　refrigerant,　compared　with　all-air　air-conditioning　system　and　air-water　air-conditioning　system.　Nevertheless,　VRV　system　is　less　applied　to　office　buildings　than　the　other　systems　because　the　system　is　lack　of　fresh　air　supplying,　united　control　system　and　data　collection.　This　paper　summarizes　the　advantages　of　VRV　system　in　office　buildings　and　presents　current　VRV　system　and　central　air-conditioning　control　methods.　In　the　end,　the　paper　puts　forward　three　ways　to　improve　VRV　system　application　in　office　buildings　by　adding　ceiling　fan　system,　transplanting　intelligent　algorithm　and　adopting　practical　office　building　for　testing　and　performance　assessment.
