Project task

We faced the task of creating a modern and effective climate control system for office premises with an area 150 м². It was important for the customer to get not only reliable heating in the cold period, but also comfortable cooling in the summer, At the same time with the lowest operational costs. Besides, The space for the installation of the outer unit was limited by the narrow passage between the building and the fence, which required a non -standard technical solution.

Basic requirements:

• Energy efficient heating and cooling of the entire office space;
• Integration with an already mounted warm floor system;
• Organization of cooling with the help;
• Optimal placement of the outer unit with limited space;
• Reliability, Ease of maintenance and durability of the system.

Answer

A thermal pump was selected to implement the project Raymer RAY-15DS2-EVI на 15 kW - inverter model with active cooling function, which is perfect for residential, and for office premises of medium area.

• Heating is implemented through a warm floor system, which provides uniform heat distribution and a comfortable microclimate.
• Cooling is provided with fancoals, pod. This avoids the installation of individual air conditioners and reduce expenses.
• A special metal stand was made for the installation of the outer unit, which raises the unit to the required height for a free fence and air release. This approach made it possible to effectively use the affordable space between the fence and the wall of the office.

Thus, We implemented a complex, An energy -efficient and aesthetically integrated solution for maintaining a stable microclimate in the office throughout the year.

1. Outdoor unit installation

Installation of the external unit of the heat pump Raymer Ray-15DS2-EVI was carried out in conditions of limited space - in a narrow passage between the wall of the building and a wooden fence. Standard installation on a concrete base or directly to Earth In this case, it was impossible for several reasons:

• Limited distance for air circulation. Due to the close location of the fence, there was a risk, that the external unit will not be able to effectively capture and throw out air, What is critical for his stable work.
• The narrow passage did not allow to leave free access to the unit from below in the case of maintenance.
• Snow accumulation protection, dirt and moisture. The installation of a thermal pump at a level of land could lead to its clogging or icing in the winter period.

Given this, It was decided to make an individual metal structure, which allows you to raise an external unit to a height of more 2 meters from ground level. The platform is securely fixed to the facade of the building and has additional supports for weight distribution. This approach was provided:

• Free air flow on all sides of the block;
• Easy access to connections and maintenance;
• Equipment protection from external influences (mechanical, atmospheric);
• Aesthetic appearance, without unnecessary spacing.

The pipelines were reliably insulated and neatly mounted along the facade, which provides stable operation even at low temperatures and minimizes energy losses. Installation was performed taking into account all the technical requirements for the placement of inverter heat pumps.

2. Installation of a freon line with compensation loops.

Since the outer block of the heat pump was mounted on an increased metal structure, There was a need to properly organize the laying of a freon line. To compensate for the height difference between the outer and internal blocks, as well as in order to avoid a possible hydraulic jacket or excess pressure in the system, The pipes were mounted in the form of bends-pin (so -called "zigzags"). Such a configuration allows:

• partially absorb vibrations and thermal expansion of pipes during the operation of the system;
• Reduce the load on compounds and fittings;
• ensure the durability and tightness of the highway in conditions of changes in temperature and pressure.

Each bend was recorded and thermal -insulated with a special insulation to protect against heat loss and the influence of the external environment. This approach allows the system to work reliably as in heating mode, and cooling.

3. Installation of the hydraulic module

As part of the project in the boiler room, the Raymer wall hydraulic module was mounted, which has become a central element of control of the heat supply system. It was installed on the wall taking into account ergonomics of access for service and safe connection to all circuit circuits. The main task of the hydraulic engine is to transfer heat from the external unit of the heat pump to internal consumers, First of all – To the warm floor.

The heat -insulated pipelines were connected to the hydraulic engine, leading to buffer capacity. This assault tank acts as a thermal energy accumulator, Due to which the system is able to work more stably and effectively even with variable temperature loads. The accumulated heat from the tank is evenly distributed to the contours of the warm floor, which allows you to maintain a comfortable microclimate in rooms without sharp temperature fluctuations.

Separately, two circulation pumps were installed, which ensure the constant movement of the coolant between the hydraulic engine, buffer capacity and floor heating system. To stabilize pressure in the closed system, an expansion tank is mounted, and also implemented the filtration of the coolant to protect equipment from possible clogging. All elements of pipelines are neatly thermal insulated, And the layout of the system allows you to conveniently maintain its maintenance in the future.

4. The value of the buffer capacity in this system

In this heating system The buffer capacity plays a key role in ensuring effective, stable and reliable operation of the heat pump. It serves as an intermediate battery, which accumulates heat, produced by a heat pump, and gradually transfers it to the warm floor system.

The main function of the buffer capacity is to smooth out temperature fluctuations and prevent the frequent inclusion and off of the heat pump compressor compressor. This allows you to extend the life of the equipment, as well as optimize electricity consumption. The heat pump works in optimal mode, generating heat in large volumes per cycle, And the excess of this energy is stored in the tank and is used in moments, when the need for heat exceeds its instantaneous production.

Besides, The buffer container helps to ensure uniform distribution of heat in all circuits of the warm floor, excluding overheating or non -income of individual sections. Thanks to this, the system operates smoothly, and the temperature in the room remains stable and comfortable. As a result – Not only the energy efficiency of heating increases, but the overall reliability of the entire system improves.

5. Installation of fancoals to ensure cooling in the summer

Within the framework of the project, not only the heating of the room was provided using a warm floor, but also the organization of cooling in the summer. Fanchoils were mounted for this – Universal internal blocks, which can be heated, and cool the air depending on the temperature of the coolant supply.

The installation of fangeals was carried out taking into account the zoning of the room and the features of the internal space. Pipelines were laid using thermal insulation to prevent thermal losses and condensation in the summer. Thanks to the integration of fancoals into the heat pump system, The user receives a full -fledged climatic system: In winter – Comfortable heating, in summer – Effective cooling without the need to install additional air conditioners.

This approach allows you to optimize the space, reduce the costs of individual equipment and achieve a high level of energy efficiency. Besides, Such a system provides a more uniform microclimate in the rooms and rapid response to a change in temperature conditions.
