What is Refnet in AC?
Refnet, also refer as Y branch copper fittings is use in connecting VRV/VRF system. Over here we refer to the first VRV system inventor for the types of REFNET and how they connect the system. Make sure each branch comes with an insulator. Each branching kit comes as a set of 2.
How does a VRF air conditioner work?
VRF systems use heat pumps or heat recovery systems to provide powerful heating and cooling for all indoor and outdoor units without the use of air ducts. With a VRF system, your building will have multiple indoor units utilized by a single outdoor condensing unit, either with a heat pump or heat recovery system.
Which refrigerant is used in VRF system?
R-410A refrigerant
VRF systems use R-410A refrigerant as the heat-transfer fluid and the working fluid, achieving a very high energy efficiency ratio (EER) of 15 to 20 and integrated energy efficiency ratio (IEER) of 17 to 25.
Can a Refnet be installed vertically?
BTW, they can be installed vertically as well, as long as the refrigerant flow is vertical (there are limitations, check the leaflet in the box they comes in), like for example in a riser.
What is a VRV system?
VRV is a technology that alternates the refrigerant volume in a system to match a building’s precise requirements. Only a minimum amount of energy is required for a system to maintain set temperatures, and ensure that it automatically shuts off when no occupants are detected in a room.
What is a 3 pipe VRF system?
Heat Recovery VRF – 3 Pipe System Each outdoor air-cooled condenser is connected via 3 pipes to an indoor heat recovery unit; a high pressure gas refrigerant line (for heating), a high pressure liquid refrigerant line (for cooling), and a low pressure gas suction line (for return to the outdoor unit).
What is VRS air conditioning?
VRV (Multi-Split Type Air Conditioners) | A multi-split type air conditioner for commercial buildings to provide customers with the individual zone control ability in each room and floor of a building.
