Advanced heat pump technology—including inverter heat pump designs and EVI DC inverter models—efficiently extracts and transfers ambient heat in temperatures as low as –25 °C. Innovations like multi‑stage compression, optimized refrigerants (e.g., R32, R290), and smart defrost control maintain COPs above 2.5 in extreme cold. Both air‑source and ground‑source systems, standalone or hybrid, deliver reliable, low‑carbon heating with economical paybacks in harsh climates globally.

Heat pumps transfer ambient heat to higher‑temperature sinks via evaporation, compression, condensation, and expansion, achieving COPs of 3–6. Although installation cost is higher, high efficiency and low running expenses lower overall heat pump cost and air source heat pump cost. Renewable heat use, low emissions, and versatility make heat pump technology ideal across residential and commercial sectors.

St Andrew’s Church, an 18th‑century landmark in the UK, recently underwent a sensitive heating upgrade that preserves its historic character while delivering modern comfort. Faced with uneven warmth, slow heat‑up times and visual intrusion from the original radiator network, the project team specified an innovative heat pump system to replace traditional radiators. After an international tender, Airosd was chosen for its leading heat pump technology and experience in historic buildings. The proposed solution centers on a modular air source heat pump system, combining three high‑efficiency units with custom controls and renewable integration. Project Highlights Heritage‑Sensitive Installation – The new heat pump system fit discreetly into existing service voids, avoiding any disturbance to St Andrew’s stone walls or stained‑glass windows. – Concealed pipework connects to underfloor heating and fan‑coil terminals, replacing bulky radiators without altering the nave’s appearance. Advanced Heat Pump Technology – Each air source heat pump draws ambient air and upgrades it to usable heat via inverter‑driven compressors. – EVI jet‑injection and smart defrost algorithms ensure reliable operation even in sub‑zero conditions, extending the scope of geothermal heating alternatives. Smart Controls & Efficiency – A central controller monitors indoor and outdoor sensors, automatically modulating output for maximum efficiency. This heat pump system can adapt to varying attendance patterns—from quiet weekday services to full‑house Sunday worship. – Integrated BMS compatibility means the air source heat pump system links seamlessly with lighting and ventilation, further reducing energy demand. Renewable Energy Integration – To complement the air source heat pump, rooftop PV panels feed a battery bank. Surplus electricity powers pumps and circulation, minimizing grid reliance and cutting carbon emissions. – When sunlight is insufficient, the heat pump system draws only the necessary grid energy, optimizing life‑cycle costs. Performance & Comfort Since commissioning, St Andrew’s has seen a 40% reduction in heating energy consumption compared to the old radiator network. Thanks to underfloor circuits and fan coils, warmth is uniform and responsive—an outcome traditional geothermal heating retrofit approaches could not achieve without extensive excavation. Why Heat Pump Technology? – Sustainability: Zero on‑site combustion and up to 5.0 COP (Coefficient of Performance) yield dramatic CO₂ savings. – Versatility: Whether on frosty winter mornings or mild autumn days, the air source heat pump adapts output, maintaining a stable interior climate. – Heritage‑Friendly: Minimal visual impact and non‑invasive installation protect historic fabric. By choosing Airosd’s air source heat pump system, St Andrew’s Church now combines centuries‑old grandeur with 21st‑century efficiency, setting a benchmark for historic building retrofits across Europe.

AIROSD's air source heat pumps are transforming Anhui's aquaculture industry, empowering the leading "Golden Turtle Enterprise" in its sustainable growth. With a focus on eco-friendly and energy-efficient solutions, AIROSD supplied 18 ultra-low-temperature heat pumps for a large-scale turtle farming project covering 32,800㎡. The heat pumps maintain optimal water temperatures (28–32°C) crucial for the growth and reproduction of cold-blooded turtles, ensuring improved metabolic rates and efficient farming. The system’s advantages include corrosion resistance, stable heating even in extreme weather, and precise temperature control, reducing labor costs. The project has led to increased farming output, reduced energy consumption, and lower operational costs. Moreover, the heat pumps support green development, aligning with national sustainability goals by eliminating waste and emissions. This innovative solution demonstrates AIROSD’s commitment to modernizing aquaculture and promoting rural revitalization.
