Exercise
The facility is located in the city of Kiliya, Odessa region, with total area 120 м². The client claimed a reduction in heating costs, since the house was previously heated with a solid fuel boiler, an electric boiler was subsequently installed.
So, how preparing raw materials and bringing them to a solid fuel boiler caused inconvenience to the owner, it was decided to install an electric boiler, but an increase in the price of electricity forced the customer to look for more economical ways to heat their home, so the choice fell on a heat pump, since it uses air energy and produces several times more kW of energy per 1 kW consumption, whereas the electric boiler gives 1 kW of heat per 1 kW consumption.
Additionally, the heat pump includes more than just heating, but also the possibility of cooling in hot months.
Answer
Taking into account the features of the house (insulation and local climate), client needs, it was decided to install a Raymer RAY-15DS1-EVI inverter heat pump (220V).
This pump features high performance and stable operation even down to -25°C, and inverter technology allows you to adapt pump operating modes depending on external temperatures.
Scope of work completed
After analyzing the house design, its ergonomic properties, location of all communications (water, electricity, sewage) a thorough plan for the installation of heating equipment was developed and a location was selected for the boiler room with the appropriate requirements for the proper operation of the heat pump and all auxiliary components of the system.
1. Outdoor unit installation
The outdoor unit of the heat pump was installed on a secure stand (made by yourself), which ensures the stability of the structure. Additionally, the outdoor unit is always installed on anti-vibration supports, to reduce vibrations from compressor and fan operation.
The location of the outdoor unit has been taken into account to ensure optimal performance and ease of maintenance.
Because, The heat pump has a good external coating, corrosion protected, and the internal electronics are well insulated, there was no need to install additional protective structures to protect against adverse weather conditions.
The freon line was well insulated with rubber and foil tape to reduce heat loss.
2. Installation of the indoor unit
The indoor unit of the Raymer RAY-15DS1-EVI heat pump was installed in the boiler room, where the solid fuel and electric boiler is already located, with the most comfortable access for maintenance.
Freon pipes from the external unit were connected with good insulation to avoid condensation during operation.
Connected and configured touch controller for heating control, cooling and domestic hot water.
A modem has been configured to control the VT remotely from a phone or any gadget, which supports Wi-Fi.
The buffer tank was not connected, since the underfloor heating system already contains 200 l water, which provides sufficient volume for heating.
3. Connecting voltage stabilizers
To ensure safe and reliable operation of the heat pump, voltage stabilizers were installed on 10 kW. This device protects the system from power surges and other possible power supply problems..
In case of possible blackouts during certain periods of the year, a voltage stabilizer is required in heating systems, powered by electricity.
Features of the heat pump Raymer RAY-15DS1-EVI (220V):
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 Raymer RAY-15DS1-EVI heat pump 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-15DS1-EVI (220V) 15 kW 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.
What does the home owner get?, installing a heat pump?
Home owner, installing a heat pump, receives a number of important advantages:
Saving on energy consumption: The heat pump uses energy from the environment, which allows you to significantly reduce heating costs, compared to traditional energy sources, such as gas or electric boilers.
Environmental friendliness: Heat pumps run on renewable energy sources, do not produce harmful emissions into the atmosphere, therefore they are environmentally friendly.
Versatility: A heat pump can be used for more than just heating, but also for cooling the room in summer, subject to installation of fan coil units, performing the function and radiators, and air conditioners.
Automation and ease of management: Modern heat pumps are equipped with automatic control systems and can be integrated with a smart home or remotely controlled via mobile applications, which increases the comfort of use.
Independence from gas and other fuels: The heat pump runs on electricity and uses energy from the environment, which makes the owner less dependent on fluctuations in gas or solid fuel prices.
Long service life and low maintenance costs: High-quality heat pumps have a long service life (20-25 years) and require minimal maintenance, which reduces overall operating costs.
Thus, the home owner receives economical, environmentally friendly and user-friendly heating and cooling system, which also increases the comfort and value of his property.
