TM44 air conditioning inspection of individual split systems:
In split systems a single outdoor unit called condenser containing refrigeration and heat rejection equipment is connected to an individual indoor unit called evaporator delivering cooling or heating. These may also be called ‘split package units’.
A single indoor unit is connected by refrigerant pipework to a single outdoor unit. The indoor unit may be floor, wall or ceiling mounted. The unit may be reversible allowing operation as a heat pump.
These types of systems are categorised as Level 3 in TM 44 Legislation and simple air conditioning inspection generally considered suitable for split systems.
