GREE - The Heart of Your Pool

Why is this solution better for you?

• Liquidity, not "Jumps" (Scope 20 to 100%): The Gree compressor acts as a gas pedal in a modern car – smoothly adjusts the power to the current water temperature. Once the pool is heated, the pump slows down, using only a fraction of the energy needed to maintain the heat.
• High Lifespan: By avoiding constant starting and stopping, components wear out much slower. It is a technology for years that offers reliability even under intensive use in the season.
• The compressor is two-rotation, the movements of both pistons balance each other. Thanks to this, the device works much quieter, and vibrations are smaller. Thanks to the better balance of mas, the compressor loses less energy for friction and mechanical resistance. Two rotary compressors can operate very stably at minimum rotational speed.

It must be taken into account that the pump power is given at a temperature of 27C degrees of air and 26C of water. As a rule, such an air temperature will last for a while, and most customers expect more than 26C of water temperature. Therefore, it is worth choosing a stronger pump so that it has a supply of energy so that it can go down to lower revolutions, and thus be more economical. She could have worked quieter. And do not walk all the time 100% but exploit less.

Latest 9 kW-C Series

When you buy from us, you get a pump from the latest distribution batch. What distinguishes the 9kWc model is that the Gree compressor design is a dual rotary type. This eliminates vibrations and makes the pump quieter. Additionally, the fan is inverter-driven. This makes the control more precise and energy-efficient than with a standard on/off fan and compressor.

What is the Real Power of the 9kWc Pump?

During the day, with an air temperature of 27°C, the pump has a power of 9kWc. In the evening, when the temperature is 15°C, the maximum power of the pump is 6.5kW.

When the air temperature drops to 10°C, the pump reaches a maximum power of 5.9 kW, and its COP drops from 3.6 to 5. At this temperature, don't be surprised if the difference between the inlet and outlet is about 1°C.

Therefore, if you want to extend the swimming season, it's worth choosing a more powerful pump:

1. It will work more quietly because it will have a power reserve to run at lower speeds.
2. At lower speeds, it will wear less because it won't be running at 100% power all the time, which will extend its lifespan.
3. When the pump is not working at 100% but at lower speeds, the COP will increase because it will be working at lower speeds, so the energy bill will be lower. And at lower air temperatures in the evening, its power won't be so weak, and we'll have a pleasant temperature in the morning. Considering that the price difference is small, it's worth investing in a larger pump so you don't have to wait long for the pool to heat up and don't have to worry about whether the summer will be cold this year.

FUNCTIONAL CONTROLLER WITH BLUETOOTH

Functional, easy-to-use controller with touch screen, heating/cooling temperature setting and operating times. With the mWiFi module, it is possible to control and preview work using a mobile application. The pumps we have come from the latest delivery, they have a built-in Bluetooth module

CONTROL OF THE FILTER PUMP

The heat pump controller also allows you to program two time intervals, operating regardless of the settings of the heat pump, in which it is possible to filter the pool.

With the mWiFi module, it is possible to control and preview work using the Aqua Temp smartphone application is a remote control over the pool installation.

The mWiFi PCWB module allows you to perform functions such as m.in.:

• turning the heat pump on and off
• setting of heat pump operating times
• choice of heat pump operating mode: heating/cooling/automatically
• setting the required water temperature in the pool
• Monthly statistics of changes in water temperature in the pool

• Current weather and weather forecast for 3 days
• setting the pump operating time
• notification of critical errors in the operation of the device
• temperature chart of the last 7 days

We offer the latest pumps that have been equipped with a Bluetooth module!

Comfort among the sounds of nature

The biggest advantage of the Gree inverter is the work culture. At lower loads, the compressor operates almost silently. Thanks to this, relaxation in the pool or rest on the terrace takes place in absolute peace, without the cumbersome hum known from older devices.

Pool heat pumps PCWBi-C thanks to the use of an inverter compressor, work with previously unattainable minimum volume level. The level of 38 dB(A) at a distance of 1 meter, achieved with the smoothly reduced efficiency of the heat pump means that when relaxing in the garden, we will primarily hear louder birdsong. So for the highest demands, when the house is in an extremely quiet area, the choice of the PCWBi-C heat pump will have additional justification.

• Sound pressure level (1m): is 38 ~ 48 dB(A).
• Acoustic power level: is 51,8 ~ 61,8 dB(A).

For comparison (view scale):

• 31 dB(A): Very quiet street without traffic, whisper up close.
• 51 dB(A): Office noise, normal conversation, moderate rain.
• For comparison (view scale):

Installation of PCWBi heat pumps is a relatively easy and quick operation. The internal system is completely hermetic and does not require interference with installation work. They are run outside the building, usually by the pool itself. The controller itself does not need complicated configuration. To connect the pool water circuit, it will be best to use a bypass. It consists of piping and 3 valves to cut off the flow of water through the heat pump, as well as its regulation. The device can also be quickly disassembled and stored for the winter in a closed room.

Connection of pool hoses

The kit makes it easy to connect hoses if you have a pool for 32mm or 38mm clamps (white reductions in the photo) Just between the filter pump and the pool overload the pool hose and insert the heat pump in this place. The closer we put the heat pump, the lower the temperature losses on the hoses. We can also mount on bypass hose on nuts, the so-called nipples that can be seen applied to the bypass on the right side, this is a very common solution and at the same time the simplest if we want to keep nuts. Although, when we cut a 32mm or 38 hose, we can buy fittings so that we can reconnect the average hose.

Special Solutions in the Construction of the PCWBi Heat Pump

The PCWB heat pump is specifically adapted for heating swimming pool water. It uses modern, quiet rotary compressors. The shell-and-tube heat exchanger built into the heat pump has a special design, where the refrigerant transfers heat directly to the flowing pool water. The built-in SIKA flow sensor protects the heat pump from a possible loss of water flow.

TITANIUM STEEL HEAT EXCHANGER

The special design of the heat exchanger and condenser, made of titanium steel, ensures resistance to pool water.

The design of the titanium heat exchanger significantly increases efficiency and provides sufficient heating power; the heat exchanger is made of high-quality titanium steel and PVC material, resistant to the chemistry used for water treatment in swimming pools

The shell-tube exchanger is also a heat pump condenser, which ensures high heat transfer efficiency. Pool water is located in the mantle part with low flow resistance, and the refrigerant flows through a coil with a developed heat dissipation surface. The coil is reinforced with handles for protection against vibrations and turbulence of flowing pool water. The resistance of the exchanger to the chemical impact of pool water is ensured by the materials used in the construction of the exchanger - titanium steel and PVC material.

Installation diagram with heat pump type PCWBi

In most cases, the use of a PCWBi heat pump requires minimal interference in the pool water circuit. The materials used and the design of the heat exchanger (condenser) allows direct flow of water through the heat pump. Low condenser flow resistance in most cases allows you to use the existing circulation pump. The heat pump is incorporated into the pool water circuit behind the filtration devices and in front of the chemical dispenser.

PROTECTION OF THE HEAT PUMP AGAINST FREEZING

The people on the evaporator cause disruption and decrease air flow, which in turn results in less free heat consumption and more compressor operation. Defrosting depends on the indications of the temperature sensor placed on the evaporator.

• AUTOMATIC DEFROSTING
• EVAPORATOR DEFROSTING MODE
• FUNCTION OF PROTECTING THE HEAT PUMP FROM FREEZING

The pump has a water cooling function in the pool if necessary.

First degree of antifreeze protection:

The protection will be activated when the water outlet temperature from the heat pump reaches between 2 and 4°C and the ambient temperature will be lower than 0°C. The E19 code will be displayed on the screen. At this point, a filter pump will be started, which will work until the water temperature reaches a minimum of 8°C or until the ambient temperature rises above 1°C. The device will then return to standby mode.

Second degree of antifreeze protection:

The protection will be activated when the water outlet temperature from the heat pump is lower than 2 °C and the ambient temperature is lower than 0°C. The E29 code will be displayed on the screen. At this point, the heat pump will be started in heating mode. The device in heating mode will work until it reaches a water temperature of at least 15°C or until the ambient temperature rises above 1°C. The device will then return to standby mode.

What is COP?

COP (Coefficient of Performance) is a performance factor that determines the relationship between free energy given into the pool and paid electricity taken from the grid.

• Principle of operation: If the pump has COP = 5, then with 1 kWh of current generates 5 kWh of heat.
• Main advantage: The higher the ratio, the lower the water heating bills.
• Variability: COP is not constant – it increases when it is warmer outside, and when the pump (inverter) is running at lower speeds.

Practical example for PCWBi 9,0kW-C:

Imagine that your pump is operating in ideal summer conditions and reaches COP = 10. Theoretically, because the air temperature of 27C happens sporadically, but we assume that the pool has already heated up, and the heat pump only maintains the temperature and the pump works at 20%

• You only use 1 kWh of pay electricity from the grid.
• The pump “pulls” additional 9 kWh of free energy from the air.
• As a result, a total of 10 kWh of heat goes into your pool.

COP variability in Polish conditions:

It is worth remembering that COP is not constant and depends on the weather and pump load:

1. Peak performance (COP 10,0): Achieved in very warm air (27∘C) when the pool is already heated and the inverter compressor has slowed down to approx. 20% of its power just to keep the temperature up. in Poland such ideal conditions are rare.
2. Standard operation (COP 4,1 – 6,0): This is the real range in which the pump operates for most of the season (at air approx. 15∘C). Even on those colder days, the 9,0 kW provides 4 to 6 times more energy than it consumes.
3. Start of the season (COP approx. 3,6): When there is only 10∘C outside, the pump must operate at full power to heat cold water. Then the efficiency is the lowest, but still cost-effective compared to electric heaters (which always have COP = 1).

The choice of PCWBi pump is the absence of hidden operating costs:

• No paid inspections: The current generation of Hewalex pumps does not require mandatory, paid service inspections, which distinguishes it from many competitive solutions.
• Ecological refrigerant R32: The use of modern refrigerant R32 (0,46 kg) provides higher energy efficiency with less environmental impact (GWP only 675).

Call me to get a pump for the pool.

Temperature Regulation: The maximum outlet water temperature is typically less than 40°C. The fact that you can set 40°C on the display does not necessarily mean it will be reached, as it depends on the insulation and capacity of the pool. The high pool volume stated by the manufacturer applies to low water heating temperatures, only in warm weather. In other words, a 13kW pump is not recommended for 50m3 of water; a minimum of 17.5 kW-B is needed. Customers buy 13.2kWc pumps for pools of 20m3 and smaller. Because frame pools are cooled by wind and low temperatures in the evening, they do not have the thermal insulation of indoor pools. The use of a solar cover is required.

• Operating at the highest speeds shortens the life of the compressor and causes more noise. By oversizing the pump, the compressor runs quieter and at lower speeds, consuming less electricity. So, if you're wondering whether to oversize the pump, the answer is yes, it's worth it. For example, in winter, for covered pools or indoors, it is recommended to oversize the pump by 3x, and even then, the pool is additionally supported by a heater or heat exchanger.

What to Consider

Heat pumps from the manufacturer are not factory-equipped with a power cord; you need to purchase a 3×2.5 mm2 cable.

CHOOSING THE INSTALLATION LOCATION to ensure the heat pump operates with the highest efficiency and declared heating power

Do not install the unit in places with limited air access, where exhaust air recirculation would occur.

Do not install near plants that could block airflow. Cold air can harm plants.

The location must continuously ensure free access to fresh and clean air and the flow of pool water. A pump in a closed room will frost up and turn it into a cold room.

Do not place the pump where there is a draft, as it will not effectively collect heat from the air.
