Inspections of VRF systems

TM44 air conditioning inspection of VRF, VRV and Multi Split Systems:

 

In Multi-split systems one or more ‘outdoor units’ containing refrigeration and heat rejection equipment are each connected to a number of ‘indoor units’ delivering cooling. These may also be called multi-split package units, and include variable refrigerant flow (VRF-VRV) systems.

In Variable Refrigerant Flow (VRF) systems number of indoor units is connected to a common outdoor unit by refrigerant pipework .The indoor units may be floor, wall or ceiling or mounted. Each indoor unit may operate to provide either cooling or heating, allowing heat transfer between zones that require cooling and those that require heating, with the outdoor unit operating in heat rejection or heat pump mode as necessary.

These types of systems are categorised generally as Level 4 in TM 44 Legislation and a full air conditioning inspection that would be appropriate usually where systems are centralised and make use of plantroom and more complex controls.
