Task
We were faced with the task of replacing electric heating in a private house area 200 square meters for a more energy efficient solution. Prior to modernization, the system worked on the basis of an electric boiler, who consumed more and more electricity every year, which led to high accounts in the winter period. At the same time, the owner wanted not only to reduce expenses, but also get autonomous, reliable and modern system with hot water supply and recirculation functions.
Basic requirements of the client:
- Significant decrease in heating costs;
- Integration with the existing warm floor system and radiators;
- Ensuring hot water supply with the possibility of rapid supply of warm water;
- fully automated and quiet in the work system.
Answer
The optimal solution was the installation of the inverter heat pump Raymer Ray-15DS2-EVI, which is able to work effectively even at low external temperatures up to -30 ° C. Thanks to the high energy efficiency ratio, This model allows you to get before 4,5 KW of heat for every kilowatte of electricity consumed. This immediately reduced heating costs several times.
The system was implemented by the following principle:
Heating: тепловой насос обеспечивает нагрев воды для теплого пола и радиаторного контура, separated through a buffer container for stabilizing temperatures.
DHW: установлен бойлер косвенного нагрева, to which the heating contour from the heat pump is connected, which allows you to get hot water without additional electric heaters.
Circulation: The line of recirculation of hot water with the pump is implemented, thanks to which hot water is available almost instantly anywhere in the house.
Installation included thorough preparation: Laying of freon tracks, installation of an external unit on a special basis, Sealing insulated pipelines, Vacuuming using nitrogen, as well as a hydraulic connection of the internal unit, taking into account all hydraulic separators.
As a result, the customer received a fully automated heating system, which works effectively at any time of the year, Providing heat, Comfort and significant saving of funds.
1. Installation of the external unit of the heat pump Raymer Ray-15DS2-EVI
В рамках этого проекта внешний блок теплового насоса был установлен на бетонное основание у фасада дома. The installation site was selected taking into account several important factors: обеспечение свободного доступа воздуха со всех сторон, Minimization of noise level for residents, as well as the convenience of laying freon tracks to the inner block.
The external unit was installed on anti -vibration supports, которые существенно снижают передачу вибраций на конструкции дома и способствуют более тихой работе оборудования. The distance to the wall is designed in accordance with the technical recommendations of the manufacturer - for unhindered air circulation.
After fixing the block, freon highways were connected to it, Electric power cable and control line. Freon pipelines before installation were carefully thermal insulated and sealed, To avoid heat loss and condensation. To prevent corrosion - the entire copper track was wrapped in a special protective foil with polyethylene foam.
Particular attention was paid to the process of vacuuming the route with nitrogen blowing, which guarantees the purity of the internal cavity of the highways and avoids moisture, which negatively affects the operation of the compressor.
Generally, The external unit is established in compliance with all norms and requirements, which ensures its effective and reliable work even in difficult weather conditions.
2. Installation of a hydraulic engine near an electric car
In this project, the Raymer Ray-15DS2-EVI heat pump was installed in a technical room next to the existing electric boiler. This arrangement was chosen not by chance - this allowed to rationally use the existing strapping of the heating system, and also simplify the connection to the hydraulic contour.
The hydraulic engine is fixed on the wall in compliance with the requirements in distance to adjacent equipment - for free access during maintenance. The freon line connects the hydraulic module to the external unit, and the hydraulic connection is made directly to the supply system and the reverse course of the coolant. The input and output of water are isolated by heat -insulating material to minimize heat loss.
Connection was carried out through a buffer container, performing the function of the hydraulic separator, ensuring stable operation of the system at variable loads. Along with the hydraulic engine, the electric boiler is also preserved - it can be involved as a backup source, For example, In the case of peak loads or maintenance of the heat pump.
The overall arrangement of the equipment is the most compact, convenient for use and allows for the continuous operation of the heating system with a high level of energy efficiency.
3. Installation of a DHW tank and tank-drive
This project implements a well-thought-out and effective system based on the Raymer Ray-15DS2-EVI heat pump with connecting a buffer capacity and a hot water supply tank (DHW).
Raymer IMP buffer capacity 60, located on the right in the photo, performs the function of the hydraulic battery and stabilizer of the system. It is connected to the heat pump of the heat pump by pipelines of the supply and return, which provides heat accumulation and eliminates hydraulic tears between the pump and consumers. Thanks to this, the system works evenly even with a variable heat load (For example, when the warm floor works in low temperature mode).
DIS tank Raymer dwhp 150, buffer, is responsible for preparing hot water for household needs. Its connection is organized through a three -way valve, which controls the direction of the flow of the coolant: In moments, when there is a need for water heating for DHW, The valve switches the flow from the buffer container to the boiler heat exchanger. After reaching a given temperature or completing a GVS-cycle, The valve sends the coolant again to the buffer container.
This scheme allows you to flexibly manage the priority: First, the system satisfies the need for hot water, and then proceeds to maintain heating. Besides, Controversial reinforcement is installed on the pipelines, circulation pumps and temperature sensors, which allow you to accurately control the process and minimize energy losses.
Due to the competent zoning and clear breeding of pipelines, the installation looks compact and organized, which simplifies maintenance and further operation.
4. Installation of a hydraulic node
In this project, a hydraulic node plays an important role, который выполняет функцию связующего звена между тепловым насосом Raymer RAY-15DS2-EVI, buffer capacity, heating and hot water supply system. Its main task is to ensure a stable distribution of the coolant, maintaining the necessary pressure in the system, as well as protecting the elements of equipment from water drivers or pressure drops.
The hydraulic node consists of a special hydraulic separator (hydraulic shootings), which includes supplying and reverse pipelines from the heat pump, Boofer and Consumers of Heat (radiators, warm floor, DIS boiler). Several circulation pumps are connected to the node, which are responsible for the circulation of the coolant in various branches of the system. Riddlers are also installed, Controversial reinforcement, Security Group, Manometers and expansion tank, which help maintain pressure in the system at the optimal level and control its work.
The hydraulic node allows the heat pump to work in the most favorable conditions - without overload and temperature fluctuations. Thanks to him, the system works effectively, Reliable and harmonious, And all components are not subject to excessive load, which positively affects their resource and energy efficiency of the entire system as a whole.
Why is this system needed?
In large houses or houses with remote bathrooms, it happens like this, that hot water reaches the crane only 20-30 seconds after the opening. This is a loss of comfort, water and money. The installation of this circulation unit provides constant circulation of warm water in the system, Therefore, it is always in pipes next to consumption points.
How works?
- The pump retracts chilled water, which remained in pipes after the last use, back to the boiler.
- The boiler warms it back to a given temperature.
- At the time of opening the crane, hot water is already in the pipe, And you don't need to wait.
