Tasks the project:
The main task of the project was the optimization of the heating system in the house area 120 sq. m. Earlier for heating, electric boilers were used in combination with the underfloor system system. However, the constant increase in electricity costs made such a decision financially unprofitable. The owner began the search for alternative heat sources, which could provide the same effectiveness, but with less energy consumption.
Data analysis and solution:
After a detailed analysis of the parameters of the house, Including the level of insulation, The volume of the coolant in the underlying system and the climatic conditions of the region, The Raymer Ray-10DS2-EVI heat pump was selected 10 kW. This device is able to fully satisfy the need for heating the house, and also ensure hot water supply and, if necessary, Cooling in the hot season, subject to the installation of fanlycels. The calculations showed, that the heat pump will pay for itself 4-5 years, which will be four times more economical than using the electric boiler.
To ensure hot water supply, an indirect heating tank Raymer DHWP150 was additionally installed 150 liters. Its capacity is enough to meet the domestic needs of the family, ensuring the comfort and effectiveness of the system.
Stages of work
1. Outdoor unit installation
To install the outer block of the heat pump, the roof of the house was chosen. This solution made it possible to optimally use the space and provide unhindered access to air for effective heat transfer.
The main attention was paid to the structures of the installation site, which was arranged on the roof. A metal frame with corrosion protection provides a reliable support for the external unit and resistance to wind loads. Additionally, the frame was equipped with anti -vibration pillows, to reduce noise and vibration level, which could be transmitted to the design of the roof.
Given the high -rise difference between the outer and internal blocks, A thorough miscase of the length and diameter of pipelines was carried out to ensure the normal functioning of the system. The installation provided for the use of reinforced freon highways, capable of withstanding pressure drops at a significant height. To reduce heating pipes were additionally insulated.
To avoid potential difficulties in the winter period, For example, icing or freezing condensate, the block was equipped with a drainage system with heating. The design also provides easy access for maintenance, which is especially important for equipment, installed at height.
Installation of the outer block on the roof made it possible not only to effectively organize the operation of the heat pump, but also preserve the aesthetics of the yard, Leaving more free space around the house.
2. Installation of the indoor unit, integration with the existing system
The internal unit of the heat pump was installed in the technical room, to provide convenient access for maintenance and effectively organize connection to other system elements. Its installation is made on a solid base, which guarantees stability and reduces vibration during operation.
To ensure multifunctionality and flexible control of thermal flows, the internal unit is connected through a three-way valve to the accumulator. This tank carries out the function of accumulating the coolant, which is used in the warm floor system. Thanks to the three-way valve, the heat pump automatically redirects heat flows between the accumulator and other elements of the system depending on the needs.
Additionally, the system is connected to the indirect heating tank, which provides hot water supply. This tank works effectively in interacting with a heat pump, Using its thermal energy to heat water.
Considering, that the house has already installed a heating system with an electric boiler and a conventional boiler, The new system was integrated into the existing. Bypasses were installed for this, which allow you to block the flow of water to the electric boiler and boiler. This approach provides the possibility of using the old system as a reserve, keeping it in working condition, but without constant electricity consumption.
All connections are made taking into account the hydraulic balance, To prevent pressure changes or instability of the coolant circulation or instability. The pipes of the coolant and the DHW contour are insulated to reduce heat loss, as well as to maintain the efficiency of the entire system.
Such a connection scheme made it possible to optimize the use of the heat pump, Providing economical heating, hot water supply and the possibility of a backup transition to the old system if necessary.
3. Providing hot water supply
Indirect heating Raymer DHWP volume 150 liters was installed as a key element of the hot water supply system. Its design made of high -quality stainless steel provides durability and reliability, And the built -in heat exchanger (zmeevik) allows you to effectively use the energy of the thermal pump to heat water.
The tank was installed on a strong floor, as close as possible to the internal unit of the heat pump. This ensured the compactness of installation, Convenient access for maintenance and minimizing heat loss in the pipeline system.
The pipes of supply and return of the coolant were connected to the coil of the tank. Through the three -way valve, automatic redirecting of thermal energy between the contour of heating was organized (tank-drive and warm floor) and DIS tank, depending on the needs of the user.
To ensure a stable supply of hot water, the connection system turned on the recirculation circuit, which avoids significant temperature changes and provides instant access to hot water.
Considering, that a regular electric boiler has already been installed in the house, The indirect heating tank was connected to a common water supply, Having created a bypass to switch between sources of water heating.
Raymer DHWP tank has an integrated layer of thermal insulation, But to minimize, heat loss also insulated the pipelines of the hot water supply system.
Installation of an indirect heating tank Raymer DHWP 150 l allowed to effectively use the heat pump for heating water. Due to the optimal location and integration into the system, Stable hot water supply for household needs is ensured, as well as the possibility of saving electricity by refusing to use an electric boiler.
4. Installation of storage tank
Storage tank for 100 liters has become an important element in the heat pump system, optimizing the operation of the equipment and ensuring the stability of the heat carrier supply. Its main function is to accumulate the coolant for the effective operation of the heating system, In particular the warm floor.
The supply tank was installed at the minimum distance from the hydraulic engine. This arrangement made it possible to reduce the length of the pipelines and minimize heat loss. The tank mount was provided on the floor, Given the load and access for maintenance.
The tank was integrated into the coolant circuit between the heat pump and the heating system (warm floor).
The tank was integrated with the remnants of the old heating system, which used electric boiler. For this, bypasses were installed, which allow you to switch the flows of the coolant between new and old equipment, depending on the needs.
The supply tank has a factory insulation, But to increase energy efficiency, pipelines were also insulated.
Why is a warm floor system best integrated with a heat pump?
The combination of a warm floor with a heat pump is one of the most effective solutions for heating the house. The main advantage of this combination is low -temperature operation, which perfectly corresponds to the features of the heat pump. The effective functioning of the warm floor requires the temperature of the coolant about 30-40 ° C, Whereas radiators usually operate at 60-70 ° C. The heat pump optimally generates heat precisely in the low -temperature range, What makes it an ideal source for such a system.
Warm floor provides uniform heating of the room from the bottom up, Creating natural comfort. In combination with the heat pump, this can significantly reduce energy costs. The effectiveness of the heat pump, measured by coefficient Cop (Coefficient of Performance), significantly increases when working in low -temperature mode, which directly affects the reduction in electricity costs.
Besides, Warm floor in combination with a heat pump provides long -term and stable operation of the system. Due to the large volume of the coolant in the contours of the floor, The coolant circulates slower, Reducing the number of turning on and off the heat pump compressor. This extends the life of the equipment and reduces the risk of mechanical wear.
Another important aspect is comfort in the summer period. The heat pump in cooling mode can work through a warm floor system, providing coolness indoors. Although the cooling of the floor has some restrictions, It is an additional way to create a comfortable microclimate without the need to install additional devices, such as fanchoils or air conditioners.
All in all, Warm floor and thermal pump is a combination of energy efficiency, Comfort and economy. Such a system is not only beneficial for the wallet, but also environmentally friendly, After all, the thermal pump uses renewable energy from the environment, Reducing carbon dioxide emissions.
