Installation of the heat pump Raymer Ray-18DS2-EVI for the house area 200 м²
Modern heating technologies allow significantly reducing energy costs and make the house more comfortable and autonomous. In this project, our team was faced with the task of converting the old heating system, which worked exclusively on an electric boiler, on a more economical and effective.
Initial conditions
House with a total area 200 M² was heated by an electric boiler. This option had significant drawbacks: High energy consumption and dependence on electricity tariffs. The owners were looking for a solution, which will reduce costs and provide stable heat even in severe frosts.
The chosen decision
For this object, the Raymer Ray-18DS2-EVI heat pump was selected, Type split system. Power in 18 kW perfectly corresponds to the needs of the house of such an area, Providing reliable heating in the winter and the ability to work in the cooling mode in the summer.
System equipment
Since the system should work not only for heating, but also for hot water supply, It was additionally installed:
- Raymer DHWP hydroelectric power plant 200 L - The best option for the family, which ensures the constant presence of hot water.
- Raymer IMP cumulative tank 60 L - used to stabilize the operation of the system and maintain the necessary energy supply.
Stages of installation
1. Installation of the outer heat pump unit
Внешний блок теплового насоса Raymer RAY-18DS2-EVI был installed on a strong metal stand near the entrance to the garage. This location was chosen taking into account the convenience of maintenance and the minimum influence on the comfort of the residents. Since the equipment works quietly, even when located close to living rooms, it does not create noise discomfort.
All technical requirements were taken into account during installation:
- Vibration isolation – special vibration-absorbing supports are installed under the external unit, which minimize the transmission of vibrations to the metal stand and ground.
- Distance to walls and obstacles – the recommended clearances on the sides and rear of the block are observed to ensure free air circulation. This guarantees efficient operation even during peak load conditions.
- Drainage organization - Condensate removal is provided, to avoid icing and accumulation of water under equipment in the winter.
- Freon route - About a length of about 10 meters, laid on the ceiling of the garage. All connections were made in compliance with technology, using high -quality thermal insulation to maintain the energy efficiency of the system.
Thus, The outer block was mounted as competently as possible - taking into account reliability, durability and ease of operation. This allows the owners to get stable operation of the heat pump in any season without risk of losing efficiency.
2. Installation of heat pump indoor unit and hydraulic components
Raymer RAY-18DS2-EVI heat pump indoor unit was placed in the garage on the back wall, where buffer tanks and a hot water tank are also installed. Это решение было принято с учетом ограниченного пространства в существующей котельной, where previously there was only an electric boiler.
Since the boiler room has a very small area, размещение всех необходимых компонентов системы именно там привело бы к усложнению обслуживания оборудования в будущем. Therefore, the best option was to move the main components to the garage.
This provides:
- Ease of access – теперь к каждому элементу (hydraulic module, buffer tanks, Baku DHW, pump groups) there is a simple and safe approach for maintenance.
- Efficient use of space – гараж позволил разместить оборудование в логичном порядке, which simplifies the routing of pipelines and cables.
- Safety and accuracy – оборудование установлено вдоль стены, all connections are made in protective boxes and insulation.
Installation in the garage allowed to integrate all the hydraulic elements of the system at once:
- Buffer capacity on 60 liters для стабилизации работы теплового насоса.
- DIS tank on 200 liters для приготовления горячей воды.
- Hydraulic wiring, which connect the system to heating the house.
This location not only made the system more affordable for maintenance, but also guarantees its stable work for many years.
3. Installation of the Raymer heat pump hydraulic pump
The Raymer Ray-18DS2-EVI heat pump was mounted directly in the garage next to buffer containers and DIS tank. This location allows you to conveniently integrate it into the hydraulic scheme of the system and provide simple access for service.
The hydraulic engine performs a key function - it is responsible for the circulation of the coolant between the external unit, buffer containers and a heating system of a house. Для этого было выполнено:
- Connection to the external unit через фреоновую трассу длиной около 10 m, which passes the ceiling of the garage.
- Hydraulic connection to the buffer container on 60 liters, which stabilizes the operation of the heat pump and protects the system from frequent launches.
- Connection of the DHW tank volume 200 liters through a three -way valve. This allows you to automatically switch the system between heating and heating hot water.
Integration of the expansion tank, which protects the system from pressure drops and ensures the stability of the work.
Electric connection with a cable for the possibility of direct heating of the hydraulicular tank from the network if necessary.
The hydraulic module is mounted at a convenient height for maintenance, All connections are made using thermal insulation and protective materials. This allows you to maintain the energy efficiency of the system and ensures its durability.
4. Connection of tanks in the system
The system used two main tank - this is a hot water boiler with volume 200 liters and buffer container on 60 liters.
The boiler is connected to a hydromodulus through a three -way valve, which automatically switches the operation of the heat pump between the contours of heating and heating water. The boiler is brought to the boiler for supplying cold water and the selection of hot, and also provides for the possibility of connecting an additional electric heater.
The buffer capacity acts as a stabilizer, aligns the operation of the heat pump and reduces the number of its inclusions and offs. Именно через нее проходит теплоноситель перед подачей в систему отопления. A safety group is installed on the buffer - a pressure gauge, automatic air vent and safety valve.
Two expansion tanks are mounted separately, mounted on the wall. One of them is responsible for compensating for thermal expansion in the heating circuit, the second is in the hot water circuit. Thanks to this, stable pressure is maintained in the system and reliable protection of equipment from water hammer and overload is provided.
5. Integration into an existing heating system
Установленная система теплового насоса органично интегрирована в уже существующую схему отопления дома. Previously, heating was based on electric and solid fuel boilers, and they were left as backup heat sources. The heat pump is connected like this:, to maintain flexibility and ensure the entire system operates as efficiently as possible.
The circulation pump of the electric boiler remains in operation, which supplies coolant to the second floor. Он работает через выключенный электрический котел, что позволяет избежать перестройки трубопроводов. For the first floor, the heating system is based on underfloor heating, therefore, the new heat pump simultaneously supplies coolant to two branches - the radiator circuit for the second floor and the heated floor circuit for the first.
Thanks to this integration, the heat pump has become the main heat source, whereas electric and solid fuel boilers can be connected to operation in case of increased loads, emergency situations or at the request of the owners. This creates a multi-level heating system with high reliability, flexibility and cost-effectiveness.
Advantages of an integrated heating system for the customer
For the customer, such a system has several important advantages..
First of all - efficiency: тепловой насос потребляет значительно меньше электроэнергии по сравнению с электрокотлом, at the same time provides stable and comfortable heating. Thanks to integration with existing heat sources, the owner receives a universal and reliable system: in case of severe frosts or an accident, you can always connect a solid fuel or electric boiler.
Another important advantage is comfort and flexibility.. Система распределяет тепло на две ветки: heated floors on the first floor and radiators on the second. This allows you to maintain an individual microclimate in each zone of the house without additional modifications..
The owner also receives energy independence and protection from rising tariffs: if desired, the system can be easily integrated with solar panels, which will further reduce costs.
And finally, important advantage - durability and reliability. Тепловой насос работает в автоматическом режиме, does not require constant control, and backup heat sources give confidence, that the house will always be warm, regardless of conditions.
