VRF (variable refrigerant flow) — called VRV by some manufacturers — is a commercial air conditioning system where one outdoor unit, or a bank of them, serves many indoor units through a shared refrigerant network.
Covering Purley and nearby
Purley sits within London's dense commercial fabric: shopfronts, offices above, studios and venues, where outdoor unit positions and access need careful planning.
That includes premises in CR8 and the surrounding districts. We also work in nearby Coulsdon, Wallington and Carshalton. We plan installations in Purley so the noisy work — core drilling, ceiling access, lifting plant — happens when it disturbs your business least.
What is included
- Two-pipe (heat pump) or three-pipe / two-pipe heat recovery system design
- Refrigerant pipework sizing, branch selectors and refrigerant charge calculation
- Leak detection where the refrigerant concentration limits require it
- Central controls, scheduling and BMS integration
- Phased installation, pressure testing, commissioning and full F-gas records

How it works in Purley
Survey and loads
We calculate loads zone by zone and check roof or plant space, risers and ceiling voids. For sites in Purley we confirm access and parking beforehand.
System design
Outdoor units, indoor units, branch boxes and pipe sizes are designed together, including the refrigerant charge and any leak detection.
Phased first fix
Pipework and controls cabling go in floor by floor, often out of hours in occupied buildings.
Pressure test and charge
The network is pressure tested, evacuated and charged with the calculated refrigerant quantity.
Commissioning
Each indoor unit is commissioned and the controls set up, with as-fitted drawings and F-gas records handed over.
Points to plan for in Purley
Leak checks
Larger VRF systems usually exceed 5 tonnes CO2 equivalent, so they need at least annual F-gas leak checks — more often at 50 tonnes and above.
Access and parking
Town-centre jobs in Purley often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
Refrigerant in occupied rooms
Because one network carries a large refrigerant charge, small rooms on the system are checked against the safety limits in BS EN 378 and may need leak detection.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Types of premises we cover in Purley
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
