Project task:
The customer's main request was to reduce heating costs, because. Previously the house was heated by an electric boiler, who consumed 1 kW of heat while giving off the same 1 kW of heat. Due to the rapid increase in electricity, the issue of an alternative to this type of heating has become acute..
Answer:
Analyzing the climate of the area, customer capabilities and existing heating system, it was decided to install a new generation Raymer RAY-15DS2-EVI inverter heat pump, which has an improved fan and compressor, having reduced noise during operation, and work perfectly with underfloor heating systems.
This heat pump has high energy efficiency indicators COP 4,82, which means, what's on 1 kW of consumed energy the Raymer RAY-15DS2-EVI heat pump produces 4,82 kW of heat.
It was decided to leave the electric boiler, as a backup power source, when the heat pump is stopped for maintenance.
Scope of work completed
1. Installation of the indoor unit
Installing the heat pump indoor unit is a key step in the heating system installation process..
We placed the hydromodule in the boiler room next to the electric boiler, buffer tank and heated floor comb in maximum proximity to each other, so that the system operates with minimal heat loss.
Buffer tank was connected, which accumulates heat for underfloor heating.
Freon pipes are connected and insulated taking into account all parameters to maintain the integrity of the pipe.
2. Installation of the indoor unit
Outdoor unit, responsible for exchanging heat with the environment, Requires correct installation for optimal performance.
The outdoor unit is located outdoors, where there is free access to air. Important, ensure that the installation location provides sufficient ventilation and does not interfere with air movement through the heat exchanger.
The outdoor unit is installed on a stable base – metal frame. Important, so that the base is level and able to support the weight of the block. The block was also installed on anti-vibration supports, to reduce noise and vibration during operation.
3. Connection to buffer tank
Buffer tank provides heat storage, reduces the frequency of pump activation and helps maintain a stable temperature in the system.
Installed coolant supply from the heat pump to the buffer tank, while the return flow was left through the electric boiler to the heated floor comb.
4. Controller setup
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 set parameters. This includes water and air temperature control, as well as system pressure.
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.
Controller equipped with 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.
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 120 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.
