As part of an approved building modernization project, the use of a heat pump system has been planned as the primary source of heating. The selected system is an air-to-water type with low-temperature units capable of operating up to 55°C, making it an efficient and environmentally friendly alternative to traditional heating solutions.
Technical Characteristics of the System
- Heating Capacity:
- Each heat pump unit has a capacity of 16.5 kW, sufficient to meet the heating demands of large spaces.
- System Type:
- The system is a split-type air-to-water system with indoor hydrobox units. This design allows for easy integration into the boiler room interior and ensures reliable operation.
- Indoor Units:
- Each indoor unit is equipped with a built-in circulation pump and a hydraulic module, including an expansion vessel and a heat exchanger. The indoor units are installed on the boiler room walls according to a pre-approved layout.
Outdoor Units and Installation
The outdoor units (condensers) of the heat pump system are mounted on standard stationary frames directly behind the boiler room. This arrangement provides a direct connection between the indoor and outdoor units via insulated copper piping. Pipes with a diameter of 15.88 mm are used for the gas line, and 9.52 mm pipes are used for the liquid line.
For additional reliability under extremely low outdoor temperatures, the condensers are equipped with auxiliary electric heaters with a capacity of 6 kW, ensuring efficient system operation even in adverse weather conditions.
Domestic Hot Water (DHW) Supply
In addition to providing space heating, the indoor units are connected to a 500-liter hot water storage tank, designed to supply domestic hot water (DHW). This solution significantly improves the building’s energy efficiency and reduces water heating costs.
Heat pump installations are not merely a modern technology but an integral part of the future of energy efficiency and sustainable development. Their potential to reduce carbon emissions and conserve energy resources makes them a leading technology in the transition toward greener energy solutions. With increasing government incentives and ongoing technological innovations, heat pumps are expected to become more accessible and widely adopted in the near future.
