DEG C when, gas fired-boiler start.
Air source heat pump COP is 2.4 to use the environment temperature of floor heating pattern for -10 DEG C, when outdoor environment temperature is more than
- 10 DEG C of the critical-temperature calculated, air source heat pump start；Outdoor environment temperature is less than the critical-temperature -10 calculated
DEG C when, gas fired-boiler start.
As a kind of transformation embodiment of the present embodiment, automatically and manually operational mode is may also set up, in automatic mode
Under, by above-mentioned setting and computational methods automatic running；In a manual mode, user independently switches Gas Boiler Heating and air-source
Heat pump heating.
As another mapping mode of the present embodiment, it can be combined with the other factors such as outdoor environment humidity and pass through experiment
The heating energy efficiency ratio of air source heat pump is determined, in this way, by the heating system scope of application of gas fired-boiler and air source heat pump is made more
Extensively, energy-saving effect is more obvious.
From the foregoing description of structures and principles it should be understood by those skilled in the art that, the present invention not office
It is limited to above-mentioned specific implementation mode, uses the improvement of techniques well known and replacement to all fall within this hair on the basis of the present invention
Bright protection domain, protection scope of the present invention should limit it by each claim and its equivalent.In specific implementation mode
The part not illustrated is the prior art or common knowledge.
