Hotel complex "Entourage" has always strived to provide its guests with a comfortable stay at any time of the year. Until recently, the main source of heat for guest houses and spa complexes was a solid fuel boiler, wood-burning. This heating method required significant costs - both financial, and physical. Regular harvesting, delivery and carrying of firewood required additional personnel and constant resources. Besides, this method was less efficient in terms of automation: it was necessary to constantly monitor the combustion process, add fuel, clean the ash pan and monitor the temperature.
With the increase in the flow of guests and the development of the complex’s infrastructure, the question arose of finding a more economical, environmentally friendly and convenient source of heat supply. The owners understood, that a large-scale complex needs a system, capable of working autonomously, stably and at the same time significantly reduce operating costs.
It was at this point that the decision was made to try a modern alternative - heat pumps Raymer, which have already proven themselves as efficient and durable equipment for heating and water heating.
Installation of heat pump Raymer RAY-32DS1-EVI for guest houses
The first stage of modernization of the heating system in the Entourage hotel complex was the installation of a heat pump Raymer RAY-32DS1-EVI. This powerful equipment is capable of providing stable and economical heating of guest houses with a total area to 400 м².
One heat pump Raymer RAY-32DS1-EVI is designed for four two-story houses each 100 m² each.
When designing the heating system, the features of the internal space and the comfort of guests were taken into account:
- First floor Each house is equipped with a heated floor system. This allows you to heat the room evenly, creating a comfortable microclimate without sudden temperature changes and drafts.
- Second floor heated with modern Raymer fan coil units. This solution provides rapid heating or cooling of air, and also makes it possible to adjust the temperature separately for each room.
Thanks to this combination - heated floors on the first floor and fan coil units on the second - the owners received the most flexible, efficient and comfortable climate control system. The Raymer RAY-32DS1-EVI heat pump operates stably even at low temperatures down to -30°C, providing optimal living conditions for guests throughout the year, since it can also work for cooling, and for heating. Thanks to this, the owner completely abandoned air conditioners.
Installation of the external unit of the heat pump Raymer Ray-32DS1-EVI
The outer block of the heat pump Raymer Ray-32DS1-EVI was installed on the side of one of the guest houses in the open space. For installation, a specially prepared platform was chosen, which guarantees the stability of the structure and protection against possible soil deformations.
The block is placed on durable racks with vibroopers, which minimize noise and vibration during equipment operation. This is especially important in a hotel complex, where the main task is to ensure the comfort of guests.
Additionally, the external unit was installed at a sufficient distance from the walls of the building, near the terrace. This approach ensures free access of air to the heat exchanger, which is critical for the effective operation of the system. Provided space for a fence, and for air release, thanks to which the equipment operates without overload.
The external unit is connected to the internal unit via a freon line, the length of which was previously calculated by engineers. The pipelines were insulated with a special insulating material, to prevent heat loss and condensation. Weather protection is also included, which extends the service life of the equipment.
As a result, the external heat pump unit Raymer RAY-32DS1-EVI integrated into the heating system of the houses as reliably as possible, in compliance with all technical requirements, which guarantees its long-term and stable operation.
Installation of the indoor unit of the heat pump Raymer RAY-32DS1-EVI
Indoor heat pump unit Raymer RAY-32DS1-EVI was installed in the technical room. Installation was carried out taking into account ease of maintenance and optimal arrangement of all system elements.
The unit is installed on the wall, which saves space and at the same time provides easy access to all connections. Inlet and outlet pipes are connected through high-quality thermal insulation: blue pipe for cold circuit and red for hot, which clearly separates the supply and return flow. This guarantees the correct circulation of the coolant between the heat pump and the heating system.
A buffer tank-drive is installed next to the inner block, which performs several functions at once: Stabilization of the work of thermal pump, heat accumulation, as well as protection against frequent inclusions and shutdown of equipment. Thanks to this, the system works more efficiently and durable.
The system is also integrated:
- circulation pump – responsible for the constant movement of the coolant along the circuit;
- expansion tank (red) – compensates for changes in water volume during heating and protects the system from water hammer;
- Controversial reinforcement – allows you to easily disconnect individual elements for service;
- Safety group with manometer and valve - provides pressure control in the system and prevents its excessive increase.
The entire system is mounted using high -quality insulated pipelines, which minimizes heat loss. The connection is made taking into account the requirements for reliability and energy efficiency, which makes it possible to fully provide heating through heated floors on the first floor and fan coils on the second floor of the houses.
Branching the system from the buffer tank
The buffer tank in this system acts as a central node, from which all heating circuits of guest houses diverge. It is through it that the heat is distributed evenly, produced by a heat pump Raymer RAY-32DS1-EVI.
There are two main directions coming out of the storage tank:
Fan coil circuit
- Supply lines are laid from the buffer tank to the fan coils, located on the second floor.
- Fan coil units work not only in heating mode, but also in cooling mode in summer, what makes the system universal.
- Thanks to this, residents receive a modern, comfortable climate at any time of the year..
Heated floor circuit
- The coolant supply is directed to the combs of the underfloor heating system.
- Thanks to smooth regulation, the temperature in the circuit is maintained at a comfortable level (usually 30–40 °C).
- Warm floors provide the main base heat on the ground floor of the houses, creating uniform heating of the room.
Each circuit is equipped with shut-off valves and circulation pumps, which allows you to precisely control the operation of individual zones and ensure optimal heat distribution.
Thus, The buffer capacity acts as a stabilizer and the “heart” of the system: it receives heat from the heat pump, accumulates it and distributes it evenly as in a warm floor, and in fan coils. Thanks to this scheme, maximum efficiency is achieved, flexibility and energy saving.
Heat pumps for SPA complex
To ensure stable comfort in the spa area of the hotel complex, Two heat pumps Raymer Ray-32DS2-EVI according to a cascading scheme. This approach allows you to effectively distribute the load and ensure uninterrupted operation of the entire system even during periods of peak energy consumption.
The advantages of the cascade scheme
The use of a cascading circuit for connecting thermal pumps in the sp-complex has a number of important advantages. Firstly, it allows you to evenly distribute the load between the two units. Thanks to this, each pump works in a more gentle mode, which not only reduces equipment wear, but also extends its service life.
Secondly, This scheme ensures reliable system reservation. When, If one of the heat pumps is disconnected for maintenance or repair, The second will continue to work. This is especially important for hotel and spas business, After all, the comfort of guests cannot depend on technical breaks.
AND, finally, The cascading scheme makes it possible to flexibly configure the operating modes. One heat pump can be involved exclusively for heating water in the pool, while the other will work for heating the premises of the complex. This approach makes the system as effective as possible, universal and economically profitable, After all, the equipment is used there, where there is the greatest need for heat.
Heating of the premises of the spa complex
To ensure comfortable conditions in all zones of the spa complex, one of the thermal pumps is involved exclusively for heating the building. The system is organized like this, that heat is evenly distributed through heated floors and fan coils. This allows you to maintain a comfortable temperature in the lounges, massage rooms, relaxation rooms and even technical rooms.
Thanks to inverter technology, the heat pump operates as efficiently as possible: it adapts its performance depending on the needs of the room and external weather conditions. This not only reduces energy consumption, but also provides a stable microclimate at any time of the year. This approach guarantees comfort for visitors to the complex and savings for its owners..
Heating the pool water
The second heat pump in the cascade system performs a separate task - heating the water in the pool. Its operation is organized through a titanium horizontal heat exchanger, where the coolant from the pump transfers energy directly to the water, maintaining a stable temperature level. This allows guests of the spa complex to always enjoy a comfortable bath, regardless of the season..
The use of a heat pump instead of traditional electric or gas heaters is much more profitable. Thanks to the high energy conversion efficiency, The pump consumes 3-4 times less electricity to ensure the same amount of heat. As a result, the owners receive not only savings, but also an environmentally friendly and safe solution for heating the pool.
The main elements and operation of the pool heating system with a thermal pump
The water heating system in the pool is built in this way, to combine the efficiency of a heat pump and the reliability of integrated water treatment.
The central unit is the heat exchanger in a stainless steel case. It is through it that heat is transferred from the heat pump coolant to the pool water. In this case, the hydraulic circuits remain completely separated: heat exchange is carried out only through metal plates, which guarantees the safety and durability of the equipment.
Two pipelines can be clearly distinguished in the system. Red pipes are responsible for the coolant contour, which comes from the heat pump. And gray pipes form the circulation system of the pool, which supplies and removes water through the heat exchanger and the filtration unit.
Water purification is carried out by the filtering system, Big Blue. Inside it is quartz sand or other filler, which delays sand, Leaves and other mechanical impurities. To maintain the chemical composition, a dosing station is used - sensors and dosing pumps are mounted on the wall, and below there are canisters with reagents. It automatically controls the pH level and disinfection, ensuring stable water quality.
An additional stage of disinfection is an ultraviolet disinfectant., metal cylinder, installed at the bottom of the system. It neutralizes bacteria and algae without the use of unnecessary chemicals, making the water more pleasant to relax in.
The locking reinforcement plays an important role - cranes with blue pens. They allow you to block individual sections of the circuit during the service and adjust the flow of water.
The operation of the system is as follows: pool water first goes through filtration, cleansing of mechanical impurities. Then it enters the heat exchanger, where he gets heat from the heat pump. After that passes through the ultraviolet block and chemical dosing, where the correct PH balance and disinfection are supported. Already purified and heated water is returned back to the pool.
In this scheme, the heat pump performs only the heating function, and the filtration and dosing system is fully responsible for the quality and safety of water. As a result, the owner receives a warm pool with clean water, suitable for daily use without any hassle.
Autonomous energy supply of a hotel complex
This hotel complex has a completely independent energy supply system based on a solar power plant.. Solar panels are located on the roof, which produce electricity from a renewable source - the sun.
This energy is fed to the Deye solar inverter, which converts direct current to alternating current, suitable for powering all hotel equipment. The inverter also serves as the “brain of the system” - it controls energy flows, distributes power between consumers, charges batteries and can release excess energy to the network.
Deye storage batteries play a special role in this system. They provide an energy reserve in case of lack of solar radiation (at night or in cloudy weather). Thanks to this, the hotel has a stable meal 24/7, Regardless of weather conditions or interruptions in the external power supply.
Thus, The whole complex works completely on its own energy supply. This not only guarantees reliability and comfort for guests, but also can significantly reduce operating expenses and position the hotel as a modern and environmentally responsible object.
Why is a thermal pump - the best solution for hotels?
A heat pump is not just a modern equipment for heating or water heating. For hotels, he becomes a real strategic solution, After all, it combines comfort for guests, Savings for the owner and reliability in daily work.
Firstly, This Energy efficiency. The heat pump is capable of 4-5 times more than thermal energy, What consumes electricity. For the hotel, where you need to constantly heat the premises, warm water in showers, pools or spa zones, This means a significant reduction in energy accounts.
Secondly, Reliability and continuity of work. The hotel works around the clock, and stopping the heating or hot water system is unacceptable. Raymer heat pumps are equipped with inverter compressors, capable of working even at -25 ... -30 ° C. And if necessary, the system can be supplemented with a backup electric boiler, To always have a spare option.
Third, This is the comfort of guests. Constant presence of warm water in the tap, stable temperature in the rooms and heating of the pool or jacuzzi - all this directly affects the customer’s experience of staying at the hotel. And here the heat pump wins over traditional boilers, because it works quietly, no odors, no combustion emissions.
Fourth aspect - environmental friendliness and image. Modern tourists increasingly value hotels, who implement green technologies. The use of heat pumps in combination with solar power plants highlights, What the hotel cares not only about comfort, but also about the environment. This is a powerful argument in advertising and for obtaining “eco-friendly” certificates..
And one more important point - gflexibility and integration. The heat pump can be connected to both a radiator heating system, as well as for heated floors, DHW boilers or swimming pool heating systems. This is a universal solution, which is suitable for any hotel complex - from small apart-hotels to large SPA centers.
As a result, the hotel receives a system, which simultaneously reduces costs, increases comfort levels and operates smoothly even in the harshest conditions. And guests receive the main thing - warmth, comfort and quality service.
