Project goal:
The main task of installing a heat pump is to replace the existing heating system based on a solid fuel boiler, since lifting raw materials and harvesting has certain difficulties and requires constant supervision. The option of replacing it with an electric boiler or heat pump was considered.
Answer:
Comparing the energy consumption costs of an electric boiler and a heat pump, as well as its additional features, such as cooling and hot water supply, the client decided in favor of a heat pump, which in 4 times more efficient than an electric body – meaning, what's on 1 kW of consumed electricity the heat pump produces 4,82 kW thermal energy, whereas the productivity of the electric boiler is 1:1.
Weighing all the client’s indicators, energy efficiency of the house, it was decided to install an inverter heat pump Raymer RAY-15DS2-EVI, which is capable of operating at ultra-low temperatures down to -30°C.
Scope of work completed
After analyzing the house design, location of adjacent communications (water, electricity, sewage) a thorough installation plan for the heating equipment has been developed and a location has been selected with the appropriate requirements for the proper operation of the heat pump and all auxiliary system components.
1. Outdoor unit installation
The outdoor unit of the heat pump is responsible for efficient heat exchange with the environment, therefore, its correct installation is key for stable and productive operation of the entire system.
The block was placed in an open space, which provides unobstructed access to air. When choosing a location for installation, take into account adequate ventilation, which is important for stable heat transfer, and also eliminated potential obstacles to the free movement of air through the heat exchanger, which can negatively affect the efficiency of the system.
The unit is mounted on a durable metal frame, which provides a reliable foundation for all equipment. Additionally ensures a uniform base, capable of supporting the weight of the unit, which is important to prevent distortions and damage to the system. To reduce noise and vibration during operation, the unit was mounted on special anti-vibration supports, which not only increases comfort during operation, but also extends the life of the equipment, reducing the load on the compressor and fan.
This placement and a set of protective measures ensure reliable and quiet operation of the outdoor unit, maintaining a stable indoor microclimate.
2. Installation of the indoor unit
Installing a heat pump indoor unit is a key step in creating an efficient heating system, hot water supply and air conditioning.
Hydraulic module, installed in a corridor niche on the adjacent wall with the outdoor unit. This arrangement minimizes heat loss, reducing heating costs and ensuring stable operation of the heating circuit.
A buffer tank is connected to accumulate and store heat, which is used by the system. This capacity allows for uniform heat distribution and effective temperature control in all rooms.
Freon pipelines, connecting the indoor unit to the outdoor, connected in accordance with all technical requirements.
High-quality connection of all elements contributes to the efficient and reliable operation of the internal unit of the heat pump, ensuring comfort and energy efficiency of the system.
3. Installing a circulation pump
Circulation pump is a mandatory element of a house heating system 150 sq. m, since it is responsible for moving coolant throughout the entire system even in the most remote corners of the house.
Pump allows you to maintain a stable flow, which reduces the load on the heat pump and increases its efficiency, reducing energy costs. Thanks to circulation, the coolant transfers thermal energy from the heat pump to all parts of the system, ensuring uniform heating of the premises. This is important to maintain a stable outlet temperature from the heat pump., allowing the system to operate at peak performance.
The circulation pump is configured in accordance with the system parameters, which allows you to maintain stable pressure and flow, ensuring reliable and uninterrupted operation of the entire heating and hot water supply system.
4. 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.
Based on the data he regulates the operation of heat pump components to achieve optimal efficiency and maintain specified parameters. This includes water and air temperature control, as well as system pressure.
System controls the work 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.
The controller is equipped with a memory function, which allows you to save settings and parameters even in the event of a power outage. Besides, it supports network connection via Tuya WIFI, which allows remote control and monitoring of the system.
The controller controls the operation of the water pump, fan, electric heaters and valves. Depending on operating mode (heating, cooling or hot water preparation), it automatically turns these components on or off, ensuring optimal system performance.
Advantages of the new generation Raymer RAY-15DS2-EVI heat pump
The Raymer RAY-15DS2-EVI heat pump has the power 15 kW, making it ideal for efficiently heating rooms up to 150 sq.m. It provides significant energy savings of up to 80% compared to traditional heating systems, which reduces heating costs.
Using green energy, this heat pump helps reduce CO2 emissions and has a positive impact on the environment.
Inverter compressor and Enhanced Vapor Injection technology (EVI)
Inverter technology allows you to adjust the pump power depending on demand, providing stable and efficient heating of the room. Thanks Enhanced Vapor Injection technology (EVI), The heat pump can operate at low temperatures down to -30 °C, which expands the possibilities of use in different climatic conditions.
New black design for better heat absorption
New design in black, as a result of the latest developments and research in the field of heating equipment for better absorption of heat from the environment, makes the Raymer RAY-15DS2-EVI heat pump the best choice among other heating systems.
Black surfaces are less susceptible to visible dirt, dust and scratches compared to white or light-colored surfaces. This reduces the need for frequent cleaning and maintenance of the device, which is user friendly.
Black has better heat absorption ability, which can be useful for outdoor units of heat pumps in the cold season. This helps prevent icing and improves operating efficiency..
Remote control
Built-in Wi-Fi module allows you to control the heat pump from a distance. Wherever you are, you can turn on/off the heat pump, and also track its performance with access to the Internet.
The convenience of this function is that, that even being on a trip, you can turn on and set the heating or cooling operation in advance, and enjoy a comfortable temperature in the house upon arrival, without waiting for the system to work at full capacity.
