SASO 2874: Large capacity air conditioners – performance requirement and methods
of testing of VRF systems,

The Kingdom’s energy-efficiency strategy, and how the community of VRF manufacturers and suppliers can substantially support and bolster countrywide decarbonisation efforts. Would key regulations and a system of incentivising best practices in design and installation prove to be a game-changer in increasing uptake?

That said, is this VRF’s time in the sun with government lifting subsidies, thus pushing energy efficiency to the forefront like never before?

The curious case of projects still being designed based on a chiller or split system, with VRF an afterthought. How much can early VRF-based design culture help, given the purported benefits of doing so, such as defining the cooling load calculation, connection ratio (combination ratio), determining the indoor unit type, outdoor location and pipe routing?

ASHRAE Guideline 41 on design, installation and commissioning of VRF systems: A review

Supporting the economy: How VRF manufacturers and suppliers can positively impact the measures being taken by owners of multi-profile buildings to lower the total cost of ownership

High-rises, high ambitions: Is there an effective strategy in Saudi Arabia to supply cooling to tall buildings, some with cooling demand exceeding 100 tonnes of refrigeration?

The progress made with connecting multiple apartments with one VRF condensing unit, in a bid to optimise costs

Mini-VRFs: Smaller footprint, flexible piping, advanced control solutions and low operating noise. Can it be argued that such typical characteristics make them a popular choices in citizen housing and general residential market in Saudi Arabia?

Are lower capacities and smaller 1.2kW size units for controlling individual area factors that matter for better acceptance of VRF technology?

Artificial Intelligence: Can it influence a regime of optimum operational conditions without compromising on comfort, leading to higher operational energy efficiency in VRF systems? Can Active AI pressure control system optimise performance by learning usage patterns?

The level of understanding about VRF systems among the architectural community, which is tasked with specifying equipment in some projects

The competency achieved over the years in proper design and installation of VRF systems, and the bulking up of an ecosystem of VRF technology-familiar technicians

The availability of – and easy access to – onsite measurable performance data. The evaluation of performance of VRF systems in New Construction and retrofit projects

VRF systems and indoor environmental quality (IEQ) – thermal comfort through zone-based cooling, and acoustical comfort (sound levels less than 58 dBA)

Solar-powered VRF systems in the context of the Kingdom’s determination to harness solar energy to the maximum as a broad strategy to enhancing energy security and addressing the need for reducing indirect emissions

The progress with refrigerants further to Kigali and the call for low-GWP (400 or less) solutions
