Air-source heat pump central heating system

　　Product Name

　　II. Performance Advantages

　　Energy efficiency: Implementing a centralized hot-water supply system powered by air-source heat pump water heaters can reduce operating costs for users’ hot-water systems.

　　Absorbing heat from the ambient air makes this a energy-saving product, significantly reducing electricity consumption compared with electric boilers.

　　Safety: The air-source heat pump water-heating unit’s centralized heating system features an advanced design, utilizes a high-efficiency refrigerant, and is safe and reliable, with no

　　Hazards such as pollution, explosiveness, and toxicity.

　　No limitations: Compared with solar energy, air-source central hot-water units are unaffected by ambient weather conditions and can operate effectively even on cloudy or rainy days.

　　Operate normally and ensure the supply of hot water.

　　Small footprint: Heat pump units feature a compact design and require minimal installation space—typically only a few square meters—making them ideal for installation.

　　There are no strict requirements for the installation location; it can be installed at any designated location without the need for a dedicated equipment room, and it features intelligent management.

　　The entire system can operate automatically, eliminating the need for dedicated on-site personnel.

　　Practical and reliable operation: The heat pump unit is controlled by an intelligent, user-friendly computer board, enabling fully automatic operation once the settings are configured.

　　Moreover, the host unit features no direct control of high-current or high-voltage circuits, ensuring safe and reliable operation with a low failure rate, and no Requires dedicated maintenance.

　　III. Scope of Application

　　It can be used for domestic hot water in hotels, inns, schools, hospitals, industrial and mining facilities, saunas, beauty salons, swimming pools, greenhouses, residential communities, villas, and other applications. It can be operated as a standalone system or integrated into a centralized heating network, with various product series and installation designs available to meet different heat supply requirements.

　　IV. Value Delivered to Customers

　　1. Reduce operating costs

　　Compared with other conventional heating methods, the initial investment can be recouped in a short period of time.

　　2. Stable operation and long service life of the unit

　　The compressor boasts a long service life, thanks to a refrigerant piping system design that leverages the heat pump principle in combination with an advanced water circuit design. This ensures that the unit’s operating pressure remains consistently close to its design pressure with minimal fluctuations, thereby guaranteeing stable system operation; it also effectively reduces high-pressure levels, keeping the compressor running under stable load conditions and extending its service life.

　　3. Green and environmentally friendly

　　Air-source heat pump water-heating units produce hot water by absorbing heat from the surrounding environment. Compared with conventional water-heating methods that rely on the combustion of coal, oil, or gas, they produce no combustion exhaust emissions, cause no pollution to the atmosphere or the environment, and consume extremely low amounts of energy. As such, they are environmentally friendly products that align with China’s current energy and environmental protection policies.

　　4. Unattended operation is achievable.

　　A powerful, fully automated intelligent control system ensures that the unit requires no dedicated on-site supervision, enabling unattended operation. It provides continuous hot water supply around the clock, and in extremely cold winters, the unit automatically defrosts. Its modular design facilitates easy installation.

　　V. Conditions of Use

　　The extreme minimum outdoor temperature is above -10°C.

　　VI. System Equipment Composition

　　Air-source heat pump units, circulating water units, insulated water tanks, piping and valves, and control systems.

　　VII. Operating Principle

　　An air-source heat pump operates via a compressor-based system to raise the temperature of cold water to a set level. The heated water is then stored in an insulated storage tank, while a recirculation and pressurization system maintains continuous circulation between the user outlets and the storage tank. The storage tank is equipped with temperature and water-level control devices: when the water temperature drops, the air-source heat pump’s circulating unit is activated, establishing a closed-loop circulation between the tank and the heat pump to maintain thermal equilibrium within the tank. A sophisticated control system continuously adjusts the operating parameters of the unit—such as tank water level, ambient temperature, and inlet water temperature—to optimize performance and ensure efficient operation.
