Task:
To the owner of the house 400 sq. m. the question arose of replacing the existing heating system, which previously operated on the basis of a solid fuel boiler, to a more efficient and economical, since preparing raw materials and bringing them to the solid fuel boiler caused inconvenience to the owner and required constant care during the heating process.
The choice first fell on an electric boiler, but after calculating productivity and energy consumption we came to the conclusion, that the cost will be even more expensive than servicing a solid fuel boiler for a given area of the house.
Answer:
Having weighed all the nuances of the existing system, house insulation, location of communications and elevation differences of the system, since the house is two storeys, it was recommended to install a heat pump Raymer RAY-32DS2-EVI, which has a super powerful compressor and fans, capable of providing heating over large areas, as well as hot water supply and cooling in summer if necessary.
So, Since the area of the house is quite large, it is necessary to additionally install a reservoir for accumulation and accumulation of coolant in the system, Therefore, it is additionally recommended to install a Raymer IMP storage tank 100 l, which is quite enough to store the coolant and supply it to the radiators.
Stages of completed work
To begin with, our specialists carefully examined the area near the house., to determine the location for installing the outdoor unit, after all, it should be a short distance from the boiler room, where will the hydraulic module be located?.
1. Outdoor unit installation
The outdoor unit had to be installed on a suspended structure between the house and the fence, because it is extremely important for the outdoor HP unit to provide access to air, so that the heat pump is guaranteed to work at full capacity.
A metal homemade structure was installed, able to withstand the weight of the block and additionally guaranteed its stability at a given height even in strong winds.
A freon line has been laid with a corresponding height difference, within the limits permitted by the manufacturer's technical specifications.
2. Installation of the indoor unit
The indoor unit is installed on a solid prepared surface in the boiler room using reliable fasteners, that would support the weight of the hydraulic module and connections.
The placement takes into account the manufacturer's specifications for clearances for ventilation and access to components for maintenance.
The hydraulic module is connected to the storage tank via a three-way valve, which distributes coolant flows, thus switching the operating modes of the heat pump.
The freon line is laid to the hydraulic module with reliable insulation, protecting pipes from damage and freon leakage.
4. Installation of storage tank
The storage tank was installed in a suspended position in maximum proximity to the hydraulic module, to reduce heat loss during coolant circulation.
Its main purpose – accumulate thermal energy, produced by a heat pump, and ensure uniform heat distribution throughout the house. The tank accumulates excess thermal energy, produced by a heat pump, when the heat demand in the house is less than the pump capacity. This ensures a stable heat level even during pauses in the heat pump operation..
5. Additional system components
The three-way valve plays an important role in the Raymer RAY-32DS1-EVI heat pump system, ensuring efficient operation of heating and hot water supply.
A three-way valve redirects the coolant between the heating circuit (radiators, warm floor) and a circuit for heating hot water in a boiler or indirect heating tank.
By controlling coolant flows, the three-way valve helps save energy, since the heat pump only works on one circuit at a time. This reduces the load on the system and increases its efficiency.
6. Controller setup
The controller receives data from various sensors, installed on the system. Sensors measure inlet and outlet water temperatures, return and exhaust gas temperature, ambient temperature, as well as the temperature of the evaporator and condenser coils. Pressure indicators are also monitored using high and low pressure sensors.
The controller analyzes the received data to determine the current state of the system. Based on this data, it regulates the operation of the heat pump components to achieve optimal efficiency and maintain set parameters. This includes water and air temperature control, as well as system pressure.
The system monitors the operation of the heat pump for possible emergency situations. If such situations arise, For example, overheating or exceeding permissible pressure, the controller can automatically turn off individual components to prevent damage.
Features of the Raymer RAY-32DS1 EVI heat pump:
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-32DS1-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-32DS1-EVI 380V 32 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.
Benefits of installing Raymer RAY-32DS1-EVI for the customer
Installing a heat pump brings a number of important benefits to the customer:
