HVAC
Conception and execution of acclimatisation instalments, with the following systems:
- VRC: the VRC system combines electronic technology with control systems through microprocessors, connected to a combination of multiple internal units, in a single refrigerated cycle. Powergol normally has this type of solution especially in large dwellings and commercial buildings and in medium to large offices.
- Split System: Refrigerating system used in air conditioning equipments that are divided in two modules, internal units (evaporator) and external units (condenser). A very common solution in Angola, due to market proposal reasons, facilitates the maintenance by effortless trade/supply of equipments.
- Chillers (Refrigerators): Removes the heat from a liquid through a refrigerating cycle by compressing steam or absorption. This liquid can be distributed through a heat exchanger in order to cool the air as a required tool. Although Powergol has qualified technicians to install these systems, it is not a common system in Angola due to its technical complexity.
- UTA's (Air treatment unit): a device used to condition and circulate air as part of a heating, ventilation and air conditioning system (AVAC). A UTA normally consists of a metal structure that contains a mechanical ventilator, heating and cooling elements, filters, noise controllers and admission and exit grids.
- RTU (Roof top Units): air treatment units that include their own independent air heating or cooling device and that are designed to be placed on the roof of a building. We have these type of devices installed in restaurants, libraries, canteens, gymnasiums and auditoriums, being the best solution for these types of buildings.
- Conception and execution of ventilation and smoke vent installations;
- Integration of all of the systems.
