For swimming pool operators and homeowners, balancing comfort, energy efficiency, and environmental responsibility is a constant challenge. COLDNOT has reimagined pool temperature control by combining its professional air-source swimming pool heat pumps with cutting-edge CO₂ heat pump technology. This integration not only delivers stable, precise constant temperatures for villas, hotels, hot springs, and water parks but also elevates sustainability—addressing both the practical needs of pool management and the global demand for low-carbon solutions.
Residential & Commercial Pools: Compact designs fit villa yards or hotel basements, while high heating capacity caters to water parks and large outdoor pools.
Specialty Pools: Hot spring and SPA pools require resistance to mineral-rich water—COLDNOT’s units use corrosion-resistant materials to avoid scaling and damage, ensuring long-term stability.
Rapid & Precise Heating: The system quickly raises pool water to 26–28°C (the optimal range for swimming) and maintains it with ±1°C precision, eliminating uncomfortable temperature fluctuations.
tion: Air-source technology draws heat from the air, operating unaffected by night, rain, or cloudy weather—critical for commercial pools that serve guests around the clock.
Comprehensive Safety Protections: 11 built-in safeguards, including earth leakage protection, compressor overcurrent protection, and anti-freezing measures, prevent accidents and minimize downtime.
Compression Stage: The compressor draws in low-temperature, low-pressure gaseous CO₂ from the evaporator and compresses it into a high-temperature, high-pressure supercritical fluid. Unlike synthetic refrigerants, CO₂ reaches a supercritical state (neither fully gas nor liquid) at moderate pressures, enabling efficient heat transfer.
Heat Release Stage: The supercritical CO₂ flows into a gas cooler, where it transfers heat to the pool water. This stage is highly efficient—CO₂ releases large amounts of heat even at high temperatures, making it ideal for heating pool water to 26–28°C (or higher for specialty needs).
Throttling & Evaporation Stage: After heat release, the high-pressure CO₂ is throttled and depressurized by an expansion valve. It then enters the evaporator, where it absorbs low-temperature heat from the ambient air (even in cool conditions around 0–10°C) and evaporates back into a gaseous state.
Cycle Repeat: The gaseous CO₂ is drawn back into the compressor, and the cycle restarts—creating a closed-loop system that minimizes energy waste.
Superior Environmental Performance: CO₂ has an Ozone Depletion Potential (ODP) of 0 and a Global Warming Potential (GWP) of 1, far lower than synthetic refrigerants. This aligns with eco-friendly pool management goals, reducing carbon footprints.
Low-Temperature Efficiency: Unlike traditional air-source heat pumps that lose efficiency in cold weather, CO₂ systems maintain stable heating even at 0–5°C. This is a game-changer for outdoor pools in temperate or cool regions, ensuring consistent performance year-round.
Energy Savings: The supercritical cycle of CO₂ enables a higher Coefficient of Performance (COP) — up to 4.5 in standard conditions. When integrated with COLDNOT’s pool heat pumps, this reduces energy consumption by an additional 20–30% compared to conventional air-source-only systems.
Smart Remote Control: Users can monitor water temperature, adjust heating modes, and receive fault alerts via mobile APP. For commercial pools (e.g., hotels), managers can check multiple pools’ statuses remotely, saving on-site inspection time.
Automatic Defrosting & Temperature Regulation: The system detects frost on the evaporator and activates defrosting only when needed—avoiding unnecessary energy use. It also adjusts heating intensity based on real-time pool usage (e.g., increasing output during peak swimming hours).
Data-Driven Optimization: Built-in sensors track energy consumption and temperature trends, providing insights to optimize settings. For example, it may lower heating slightly during nighttime when the pool is unused, further reducing costs.
