HEAT PUMPS INSTALLED INDOORS
The air/water heat pump installed indoors takes in air from the environment via a grille in the façade, thus using the same energy source as a heat pump for outdoor installation. This requires air ducts to direct the outside air to the heat pump and back outside again.
Air ducts made of EPP are usually designed as half-shells or rings locked together by means of a tongue-and-groove connection.
Such systems stand out for their good thermal insulation, low weight and reliable seal. Even 90-degree elbows can be added without flow resistance, and take up very little space.
It is of advantage that the technical equipment is installed inside the building and can be directly coupled with a ventilation unit.
The result is a modular energy supply concept whose chassis is itself a highly functionalised system.
All components are installed tightly and securely into the multi-part EPP chassis, which holds them in place.
This is based on the successful NOVAplex® design concept. The basic idea is simple: use slots rather than screws for the components. This not only saves time during assembly and maintenance, but also costs for fastening elements.
HEAT PUMPS INSTALLED OUTDOORS
The outdoor unit of a heat pump combines all important technical components of the heat recovery process in a compact manner. Inside the casing, moulded parts made of expanded polypropylene (EPP) from RUCH NOVAPLAST ensure that the individual components are held securely in place.
Tolerance optimisation
Depending on the extent of integration, one particular challenge is to manufacture all individual parts such that they are perfectly matched to each other and there is no misalignment. The mould part tolerances are kept correspondingly tight.
Sound insulation
Outdoor heat pumps and air conditioning units often cause a noise level that can be experienced as irritating. The remedy here is an EPP sound insulation hood.
On the one hand, sound insulation is achieved by the sound-reducing effect of the material EPP, often as a composite solution in combination with other materials. On the other hand, the design of the sound insulation hood ensures the optimum reduction of noise by cleverly redirecting the airflow.
The surface-finished casing also offers protection against vandalism as well as weather influences such as hail, snow drifts or solar radiation.
It is also possible to mount outdoor heat pumps directly on the façade of the building. Façade mounting elements from RUCH NOVAPLAST are useful here.
