Project task
The customer received a request to select equipment for the home at 110 sq.m., to reduce heating costs, but maintaining thermal performance even at low winter temperatures. In the face of constantly rising energy costs, it is simply necessary to look for alternative heating sources, That’s why the customer was interested in heat pumps, which have the ability to work for cooling, heating and hot water supply.
Answer
Analyzing the thermal insulation of the house, climatic features of the area, it was recommended to install the new generation Raymer RAY-10DS2-EVI, which has higher efficiency indicators in contrast to the previous version and gives 4,9 kW of heat per 1 kW of consumed electricity, that is, it saves up to 80% resources used compared to electricity- or solid fuel boilers.
Hot water supply will be provided using a Raymer G180/65 hybrid tank, which includes a buffer capacity, and a tank for heating water.
Heat pump control will be configured via Wi-Fi, which provides ease of use and the possibility of remote control.
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 thermal equipment and system connections was developed, freon line from the outdoor unit to the hydraulic module.
1. Outdoor unit installation
The outdoor unit of the heat pump was installed on a secure stand (factory) with anti-vibration mounts, which ensures the stability of the outdoor unit when the compressor and fan are operating.
The outdoor unit was installed adjacent to the wall with the boiler room, to simplify the circulation of coolant in the system.
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 laid underground and well insulated with rubber tape from external damage - this helps reduce heat loss during heat transfer.
2. Installation of the indoor unit (hydraulic module)
Installing a hydronic module for a heat pump is a key step in connecting the heating and hot water supply system. The hydraulic module is responsible for coolant circulation, regulating flows and maintaining a stable temperature in the system.
The freon pipe from the outdoor unit and the heating and hot water supply circulation pipes are connected.
Electricity fluctuations in the area are taken into account, as well as frequent power outages, therefore the hydraulic module was connected to voltage stabilizers, ensuring the stability of the system and the safety of equipment from damage.
3. Hot water connection
So, as a heat pump RAY-10DS2-EVI has the ability to connect and control DHW, it was decided to install a hybrid tank on 245 liters consisting of two parts, united in one building: buffer tank on 65 liters, located below, and a tank for heating hot water (DHW) на 180 liters with built-in coil area 3 square meters, placed on top.
Tank bodies are made of stainless steel. THEIR 304 — 1,2 mm, and the built-in coil is made of SUS brand stainless steel 316. The tank has high-quality insulation made of thick polyurethane. 55 mm, which allows the system to be used for heating, and for cooling.
5. Installing additional system components
This Raymer RAY-10DS2-EVI heat pump system is equipped with a three-way valve (which is necessary when providing simultaneous heating and hot water supply) and circulation pump, performing important functions for the efficient operation of the heating and hot water supply system:
Three-way valve distributes coolant flows between different circuits - between heating and hot water supply tank (DHW). Switches coolant between different zones. When, when heating of the DHW boiler is required, the valve redirects the flow from the heating circuit to the boiler, and after heating it returns to heating the premises.
Circulation pump ensures coolant circulation in the system, as for heating, as well as cooling. Constantly moves coolant through the heat pump heat exchanger and throughout the system. This allows heat to be evenly distributed throughout the rooms, and also ensures efficient heat transfer to the heated floor, radiators and hot water tank.
Together these components ensure efficient operation of the heating system, switching between modes and stable coolant circulation.
6. Connecting voltage stabilizers
To ensure safe and reliable operation of the heat pump, it was installed 3 voltage stabilizer AWO.
If the voltage is low or too high, motors and compressors may overheat, which leads to their malfunctions. The stabilizer prevents such situations, maintaining optimal equipment operation.
Without a stable power supply, the heating system may operate intermittently or not start at all.. Stabilizers avoid such problems and ensure uninterrupted operation even with significant voltage fluctuations.
When the system is running consistently at the correct voltage, electrical equipment operates more efficiently, which helps reduce energy consumption. This is especially important for heat pumps, which operate for a long time and require a constant supply of electricity.
Advantages of the new generation Raymer RAY-10DS2-EVI heat pump
The Raymer RAY-10DS2-EVI heat pump has the power 10 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-10DS2-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 color 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.
New, improved controller with advanced features
Controller CCHW004 for inverter heat pump Raymer RAY-10DS2-EVI Provides precise temperature control and efficient heat pump control, which allows you to achieve high efficiency and reliability of the heating and cooling system.
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.
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.
