In this Schedule —“single‑phase non‑ducted room air‑conditioner” means an encased assembly or assemblies of one or more evaporators, compressors and condensers, designed to be used together as a permanently installed piece of equipment to provide conditioned air to any enclosed space, and —| (a) | includes a prime source of refrigeration for cooling and dehumidification; and | | (b) | may include other means for dehumidifying, circulating and cleaning the air in the enclosed space; |
|
“single‑phase variable refrigerant flow (VRF) air‑conditioner” means an encased assembly or assemblies of one or more evaporators, compressors and condensers, designed to be used together as a permanently installed piece of equipment to provide conditioned air to any enclosed space, that satisfies all of the following:| (a) | the equipment is of the variable refrigerant flow type; | | (b) | the equipment has one outdoor unit that services a network of indoor units; | | (c) | the outdoor unit of the equipment is connected to a single common refrigerant pipe, which in turn branches out to connect to each of the indoor units of the equipment; | | (d) | the number of indoor units is not limited by the number of connectors on the outdoor unit that may be connected to the common refrigerant pipe; | | (e) | the equipment uses a single‑phase power supply; |
|
| “split type (inverter) air‑conditioner”, in relation to a single‑phase non‑ducted room air‑conditioner, means such air‑conditioner having an assembly of components of a refrigeration system fixed on 2 or more mountings to form a matched functional unit that employs technologies that vary the output of the compressor, by means other than start‑stop operation; |
| “split type (non‑inverter) air‑conditioner”, in relation to a single‑phase non‑ducted room air‑conditioner, means such air‑conditioner having an assembly of components of a refrigeration system fixed on 2 or more mountings to form a matched functional unit that employs technologies that control the output of the compressor by start‑stop operation. |
