How to Have an Ice Bath Swimming Pool in Summer

Heat Pump

As summer temperatures climb, turning your swimming pool into a refreshing ice bath oasis might seem like a challenge—but not with Flamingo's innovative R290 Smart PV Direct-Driven Inverter Swimming Pool Heat Pump. Designed for ambient temperatures up to 60°C, this eco-friendly system leverages solar power to efficiently cool pool water to invigorating low temperatures, perfect for therapeutic ice baths. Whether you're seeking recovery benefits or a cool escape from the heat, here's how this advanced heat pump makes it possible, all while minimizing energy costs and environmental impact.

The Cooling Mechanism: Reversing Heat Pump Technology for Summer Chills

Flamingo's R290 Swimming Pool Heat Pump operates as a reversible air source heat pump, capable of both heating and cooling modes. In cooling mode, it extracts heat from the pool water and releases it into the ambient air, lowering water temperatures to as low as 5°C—ideal for ice baths that promote muscle recovery, reduce inflammation, and boost circulation.

The process involves key components:

  1. Evaporation and Heat Extraction: The system draws in warm pool water over the evaporator coil, where the R290 refrigerant—a low-GWP, ozone-friendly option—absorbs heat from the water, turning into gas. This step is enhanced by the patented efficient heat exchanger, which features a high interface between the shell and tubes for superior cooling flow.

  2. Compression and Heat Release: Powered by a Twin-rotary DC Inverter Compressor, the gaseous refrigerant is compressed and sent to the condenser, where heat is expelled via a hydrophilic-coated air exchanger with anti-corrosive fins for high efficiency.

  3. Expansion and Cycle Continuation: The refrigerant expands through the world-famous EEV (Electronic Expansion Valve) with PID control, accurately regulating volume to reduce energy consumption. The cycle repeats, maintaining stable low temperatures.

  4. Water Circulation: Built-in features like the spiral titanium tube in PVC condenser and advised water flow rates (3-4 to 8-10 m³/h depending on model) ensure even cooling throughout the pool.

This setup provides trouble-free operation with automatic setpoint control, short cooling times, and extended runtime for sufficient cold water supply.

Harnessing Solar Power: PV Direct-Driven for Sustainable Summer Cooling

In sunny summer conditions, the R290 Heat Pump shines with its photovoltaic (PV) direct-driven function, allowing solar panels to power the system directly without grid reliance. This not only cuts electricity bills but also aligns with green living.

  • Solar Panel Recommendations: Based on horsepower (HP), configurations ensure at least 95% of the pump's consumption is met by solar. For example, a 1 House power unit (230V) needs 4 panels in series (1800W total), while a  3House Power (230V) requires 8 panels (3600W). Panels are standard 450W/48V, connected in series for voltage boost or parallel for power increase.

  • Efficiency Boost: The DC inverter technology saves up to 75% energy compared to fixed-speed units, with COP values reaching 6.23 in heating mode and strong EER in cooling. In full sun, the system runs stably, cooling your pool to ice bath levels without electricity.

Additional features include a full DC inverter ultra-quiet fan motor, Wi-Fi for remote control, and a clear controller panel supporting multiple languages for easy on/off, temperature setting, and mode selection.

Why It's Perfect for Summer Ice Baths: High Performance and Eco-Benefits

Summer heat can make pools uncomfortably warm, but Flamingo's R290 series counters this with:

  • Eco-Friendly Design: R290 refrigerant offers lower emissions than R32 or R410A, with no ozone damage and a GWP of just 3—making it a sustainable choice.

  • Durability in Heat: Operates reliably from -5°C to 60°C ambient, with IPX4 waterproofing and strong counter-current design for patented C&S heat exchanger reliability.

  • Versatile Models: From 15-40 m³ pools (FLM-AH250Y/290) to 45-90 m³ (FLM-AH70Y/290), with power sources from 220V/1Phase to 380V/3Phase.

The system's detailed features, like PID control for precise refrigerant flow and hydrophilic coatings for efficient heat transfer, ensure consistent cooling even in ultra-high temperatures.
