What types of air source heat pump heating systems are there?

(1) Air source heat pump + radiator (radiator); the water supply temperature is generally around 55°C. Advantages: The replacement is simple and can directly replace the original boiler heat source; compared with the direct electric heating method, the energy saving effect is significant; compared with the electric boiler heating method, it saves the cost of increasing the power capacity. Disadvantages: high-temperature heating, slow indoor heating, poor thermal comfort, and occupying a certain amount of space.

(2) Air source heat pump + fan coil unit; the water supply temperature is generally around 45°C. Advantages: The room heats up quickly; the fan coil unit in each room is independently controlled, which is conducive to energy saving; the water supply temperature is lower than that of the radiator, the air source heat pump has a high energy efficiency ratio and saves operating costs; the system is simple, flexible and convenient to install; the system It can be used for two purposes, heating in winter and cooling in summer. For users with cooling needs in summer, the comprehensive initial investment cost is lower. Disadvantages: Slightly less comfortable, slightly noisy, and will lose some power.

(3) Air source heat pump + ground radiant heating; the water supply temperature is generally around 35°C. Advantages: energy saving, low operating costs; high comfort; the system has a certain heat storage function and good thermal stability, which can effectively offset the heating power fluctuations of the air source heat pump in extreme weather, making the system operation more stable and reliable. Disadvantages: Renovation of existing buildings will destroy the original ground; for building construction, it will also reduce the height of the room; if there are construction quality problems, maintenance will be difficult.

(4) Air source heat pump direct condensing heating (including hot air blower, waterless floor heating, etc.). Advantages: simple system, easy installation and maintenance, low failure rate; high energy saving. Disadvantages: poor comfort; slight noise.
