through these underground pipes and depending on time of
year, they are either heated or cooled by the temperature of the
ground. This water then travels to an indoor unit, where a fan,
pump and compressor are used to deliver temperate air to other
parts of the house or building.
Although the HVAC sector is looking towards a greener
future, one aspect of its installation remains the same, the need
for system piping solutions. The downfall of many solutions is
the unplanned system efficiency primarily due to piping issues,
and particularly in the leaking of the HVAC units.
As an HVAC system is a closed loop, the fluid (refrigerant)
or water inside the system must flow effectively without
escaping. A properly functioning HVAC system relies heavily
on the availability of the fluid or refrigerant to ensure proper
operation.
In order to mitigate leaks, grooved mechanical couplings can
be used to join sections of piping, and provide an effective seal.
The couplings do not require skilled labour to install, and with
merely simple tools, the installer can fit the coupling with the use
of two integrated nuts and bolts.
Negating the need for skilled labour as well as its quick
installation properties results in reducing costs, empowering
installers with a solution that is beneficial to their businesses.
Victaulic grooved mechanical couplings also provide thermal
and seismic accommodation properties, as well as vibration-
dampening which are particularly evident in HVAC projects. RACA
