In a heat pump system, the buffer tank is an indispensable component. When the heat pump starts or stops, it effectively cushions the flow changes within the system, protecting the heat pump equipment. During heating or cooling processes, it stores excess heat or cold energy and releases it promptly when demand increases, thereby improving the system's response speed and energy efficiency.

In a heat pump system, fan coil units are important terminal equipment. The cold/hot water generated by the heat pump is conveyed through pipes to the fan coil unit. The fan sucks in the indoor air, exchanges heat with the cold/hot water in the coil, and then returns the regulated air back into the room to achieve cooling or heating.

European R32 Heat Pump: EVI Strong Heating Technology for Reliable Low-Temperature Performance

This European series R32 heat pump is engineered with DC Inverter EVI (Enhanced Vapor Injection) technology at its core, ensuring powerful and consistent heating performance even in extreme cold conditions. It delivers a complete climate solution—providing space heating, cooling, and domestic hot water year-round.

Introducing the HEMS Optimized R290 Smart Heat Pump—where intelligent energy management meets sustainable heating performance. Purpose-built for modern homes and forward-thinking professionals, this advanced unit seamlessly integrates with your house energy management system to intelligently shift operation during peak solar hours or off-peak tariff periods, maximizing savings and self-sufficiency.

The domestic water tank works in coordination with the heat pump. After the heat pump heats water, it is stored in a water tank. When there is a demand for hot water, such as for daily washing and kitchen use, it can be supplied stably and promptly. Even when the heat pump is not in operation, the hot water in the water tank can still meet the usage for a period of time, ensuring an uninterrupted supply of hot water for the household and enhancing the convenience and comfort of life.
