Control method and the heat pump machine of the source pump proposed according to embodiments of the present invention are described with reference to the accompanying drawings
Group.
Fig. 1 is the flow chart of the control method of source pump according to embodiments of the present invention, and Fig. 2 is according to the present invention one
The structural representation of the source pump of embodiment.
As in figure 2 it is shown, source pump can include compressor, floor heating, radiator, the first water pump and the second water pump, the first water
The outlet of pump is connected with the water inlet of radiator and the water inlet of the second water pump respectively, the outlet of the second water pump and floor heating
Water inlet is connected, and radiator and floor heating provide respectively to N number of room, and wherein, N is positive integer.
As it is shown in figure 1, the control method of source pump can comprise the following steps that
S1, obtains current outdoor ambient temperature, and the duty of the radiator that warms up with obtaining.
S2, according to current outdoor ambient temperature, the radiator that warms up duty obtain source pump water outlet set
Temperature.
S3, according to the water outlet design temperature of source pump, the duty of the radiator that warms up to compressor, the first water pump
It is controlled with the second water pump.
Specifically, when source pump warms up radiator with including simultaneously, due to ground warm up radiator need refrigeration
Or the water temperature difference heated, such as, when heating, when reaching identical temperature, warm corresponding leaving water temperature of only turning up the soil
It is 35 DEG C, and only opening leaving water temperature corresponding to radiator is 55 DEG C, if being set to identical leaving water temperature 55 DEG C, then may make
Become the wasting of resources.Meanwhile, at a temperature of varying environment, ground warms up the refrigeration needed for radiator or the water temperature that heats also is different,
Such as, when heating, outdoor environment temperature is the lowest, no matter is floor heating or radiator, and corresponding leaving water temperature all can phase
Should raise.Therefore, it can according to current outdoor ambient temperature, the duty of the radiator that warms up obtain going out of source pump
Water design temperature, and according to water outlet design temperature, the duty of the radiator that warms up to compressor, the first water pump and the second water
Pump is controlled, thus reaches energy-conservation effect.
According to one embodiment of present invention, according to current outdoor ambient temperature, the radiator that warms up duty lead to
Crossing the water outlet design temperature of the water outlet temperature setting curve acquisition source pump preset, wherein, water outlet temperature setting curve includes
Heat low temperature setting curve, heat high temperature setting curve, refrigeration low-temperature setting curve and refrigeration high temperature setting curve.
Specifically, in source pump, the ground radiator that warms up may each comprise heating mode and refrigeration mode, in difference
Mode of operation and outdoor environment temperature under, the warm up water outlet design temperature of source pump corresponding to radiator of ground is different, because of
This, can be divided into 4 kinds according to mode of operation and outdoor environment temperature by water outlet temperature setting curve.Such as, heating shown in table 1
Low temperature setting curve, heats high temperature setting curve shown in table 2, the refrigeration low-temperature setting curve shown in table 3, and shown in table 4
Refrigeration high temperature setting curve.
