Project task
Resident of the village of Ryasne Russkoe, Lviv region, asked to select equipment for heating his house with an area of 110 sq. m. Radiators are installed in the house, the task was to provide hot water supply for a family from 4 Human.
Answer
Weighing all the customer’s options, ergonomics at home, insulation, it was decided to install a Raymer RAY-10DS1-EVI inverter heat pump with a capacity 10 kW, which is highly efficient and significantly reduces energy costs.
Thanks to the high energy efficiency ratio 3,6 this heat pump is almost 4 reduces utility bills by a factor.
Scope of work completed
The process of installing a Raymer RAY-10DS1-EVI heat pump in a private house with an area of 110 sq. m, consisted of several stages, each of which was thought out in detail and carefully executed.
1. Calculation of equipment based on the thermal capabilities of the house.
The customer's house is insulated from the outside with thick foam plastic 50 mm, which creates good heat-saving capabilities. Considering, that winter temperatures in western regions can drop to -20°C, the decision was made to install an inverter heat pump, which easily adapts to sudden temperature changes without losing heat transfer.
2. Outdoor unit installation
The outdoor unit of the heat pump was installed on concrete pillars, which ensure the stability of the block structure, as well as anti-vibration feet to reduce vibrations from the ground surface during compressor and fan operation.
The location of the outdoor unit has been taken into account to ensure optimal performance and ease of maintenance, as well as uninterrupted access to air for reliable fan operation.
The heat pump line was installed in compliance with all necessary technical standards and manufacturer’s recommendations.
3. Installation of the indoor unit
Despite the limited space in the boiler room, the indoor unit was able to be compactly laid out together with the hot water tank and other auxiliary components of the system (expansion tanks and stabilizer).
The hydraulic module is installed on a prepared surface on strong brackets to ensure stability of the structure and other connections.
A hybrid tank was connected to the block, which accumulates coolant for the heating system and hot water supply for domestic needs.
4. Connecting a hybrid DHW tank
Connecting the Raymer hybrid tank is an important step in integrating the heating and hot water system with the heat pump. Hybrid tank provides storage and efficient distribution of thermal energy, using a heat pump as an energy source, so and, if necessary, additional electric heater.
The inlet and outlet pipes are connected to the heat exchanger of the heat pump, which circulates coolant in the water heating system.
A three-way valve is installed to switch the coolant between the heating system and the tank, when priority is given to water heating.
The outlet from the tank is connected to the home's hot water system to supply heated water to taps or other points of use.
The hybrid tank has an electric heater, which is activated in cases, when the heat pump is not enough to achieve the desired water temperature.
It can work automatically, turning on when the temperature in the tank drops below a preset level.
5. Connecting a voltage stabilizer
It is also possible to install a voltage stabilization system during blackouts. This is especially important to protect the heat pump, since possible fluctuations in electricity can lead to premature wear or even failure of equipment.
Despite, that the heat pump is now working without problems, installing a stabilizer will provide an additional level of safety and avoid the risk of system damage.
Thus, Voltage stabilization will be an important investment for long-term and trouble-free operation as a heat pump, and the entire heating system, reducing the likelihood of emergencies and repairs.
6. Testing and setting up the system
After completion of installation, a thorough check of the entire system was carried out. Experts tested the operation of the heat pump in various modes, configured settings for optimal performance and ensured all components are connected and functioning correctly.
7. Instruct the client
After completing all the work, the specialists provided detailed instructions to the client on the use and maintenance of the heat pump. The client received all the necessary knowledge to effectively use the new heating system and save on energy costs.
Features of the heat pump Raymer RAY-10DS1-EVI:
Energy Saving
A heat pump is an energy-saving heating solution. Heat pump heating systems can save up to 80% electricity compared to traditional methods. This occurs by using heat from the environment for heating instead of directly producing heat.
Comparative analysis shows, that even in cold conditions the heat pump is able to operate efficiently, providing warmth in the house while reducing energy consumption.
Ecological cleanliness
Particular attention should be paid to the environmental friendliness of the heat pump. The use of R410a freon makes it an environmentally friendly option. Reduced CO2 emissions help combat climate change and make the pump more resilient to environmental challenges.
Quiet operation and comfort:
Raymer heat pump has silent operation, which allows its use in various residential premises, without disturbing comfort.
The built-in cooling function in the standard version of the pump ensures a pleasant indoor microclimate even in the hot season.
Inverter technology
Inverter technology in the heat pump allows the pump power to be adjusted depending on actual needs. It means, that it operates at maximum efficiency, adapting to changes in external conditions.
The advantages of such a system are more stable and comfortable heating, as well as additional energy savings.
EVI technology
EVI technology (Enhanced Vapor Injection) in the heat pump Raymer RAY-10DS1-EVI – this is an advanced feature, which increases the efficiency and performance of the heat pump, especially in low temperature conditions. EVI technology works by injecting additional steam into the compression process, allowing the heat pump to maintain higher levels of efficiency even when operating in colder climates.
In a standard heat pump, when the outside air temperature decreases, COP, usually, is decreasing. However, with EVI technology, the heat pump can optimize its performance by regulating the refrigerant flow and injecting additional steam. The result is increased thermal output and efficiency, which makes the heat pump more suitable for operation in winter conditions.
Remote access via Wi-Fi
The pumps are equipped with a remote access function via Wi-Fi. It means, that you can control the pump and monitor its operation using a smartphone or computer from anywhere, Where can I get access to the Internet.
Reliability and durability
Heat pump Raymer RAY-10DS1-EVI split system, is characterized by high reliability and durability. Modern technologies and high-quality materials ensure long service life of the equipment.
The experience of using the pump is confirmed by positive user reviews, who note the stability of work and level of comfort, provided by this equipment.
