Description
Technical field
The utility model relates to heat pump, is specifically related to the heat pump that a kind of photovoltaic and mains supply are seamless and connect.
Background technology
Solar energy is a kind of inexhaustible, nexhaustible clean energy resource.In global environmental pollution and energy crisis serious day by day today, the utilization of research solar energy to alleviating energy crisis, preserve the ecological environment and guarantee that economic sustainable development is significant.At present, because China's photovoltaic technology compares with advanced country in the world and still have many gaps, and it is higher to set up large-scale independent photovoltaic power station operating cost, and therefore, the exploitation family seems very urgent with photovoltaic parallel in system.
As shown in Figure 1; The electric weight that small-sized solar power generation system produced of prior art generally is stored in the storage battery earlier; Use as accessory power supply, rather than directly supply power for operating equipment, this just greatly limitations the range of application and the service efficiency of small-sized solar power generation system.
The utility model content
The technical problem that the utility model will solve provides the heat pump that a kind of photovoltaic and mains supply are seamless and connect, and enlarges the range of application of small-sized solar power generation system, improves the service efficiency of small-sized solar power generation system.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
The heat pump that a kind of photovoltaic and mains supply are seamless and connect; Comprise solar power system, monitoring module, commutator transformer, AC-DC conversion module and direct current heat pump; Said monitoring module links to each other with said solar power system, utility grid, said commutator transformer and said AC-DC conversion module respectively, and said direct current heat pump links to each other with said AC-DC conversion module with said commutator transformer respectively.
The heat pump that described photovoltaic and mains supply are seamless and connect, wherein said solar power system comprise photovoltaic battery panel, MPPT control module, and the output of said photovoltaic battery panel links to each other with the MPPT control module.
The heat pump that described photovoltaic and mains supply are seamless and connect, wherein said direct current heat pump comprises direct current compressor, variable-speed controller, said direct current compressor links to each other with said variable-speed controller.
The beneficial effect of the utility model: the utility model through monitoring module to the fusion of being incorporated into the power networks of solar power system and utility grid; Make heat pump preferentially use the electric energy of solar power system; In case monitoring the power of solar power system drops to when being not enough to drive the heat pump operation; Promptly power up, deficit power is carried out dynamic compensation through switch activated utility grid.The supply power mode of this " instant getting "; Be different from traditional batteries to store energy mode, saved intermediate links such as storage battery, realized seamless link with electrical network; Saved application cost greatly; Reduce the use threshold of solar energy, therefore enlarged the range of application of small-sized solar power generation system, improved the service efficiency of small-sized solar power generation system.
Description of drawings
The utility model comprises following accompanying drawing:
Fig. 1 uses pattern diagram for the prior art solar power system;
Fig. 2 is the utility model sketch map;
Fig. 3 is the utility model solar power system sketch map;

Embodiment
According to accompanying drawing and embodiment the utility model is done further explain below:
As shown in Figure 2; The utility model comprises solar power system, monitoring module, commutator transformer, AC-DC conversion module and direct current heat pump; Monitoring module links to each other with solar power system, utility grid, commutator transformer and AC-DC conversion module respectively, and the direct current heat pump links to each other with the AC-DC conversion module with commutator transformer respectively.System is set to preferentially use the solar power system power supply; And monitoring module is monitored the power of solar power system; If the power of solar power system drops to when being not enough to drive the operation of direct current heat pump; Promptly power up, deficit power is carried out dynamic compensation through switch activated utility grid.When using the solar power system power supply; Commutator transformer boosts to the output dc voltage of solar power system; To satisfy the direct voltage requirement that drives direct current compressor; When using the utility grid power supply, the AC-DC conversion module converts the alternating current of utility grid into direct current, to satisfy the direct voltage requirement that drives direct current compressor.
As shown in Figure 3, the front end of photovoltaic battery panel is provided with MPPT (Maximum Power Point Tracking, MPPT maximum power point tracking) control module, makes photovoltaic cell always work in maximum power point, to satisfy the power requirement of direct current heat pump.
As shown in Figure 4, the direct current heat pump is provided with variable-speed controller, and variable-speed controller detects the surrounding environment parameter of direct current compressor, then adjusts the motor speed of direct current compressor, further reduces the power consumption of direct current compressor.
Those skilled in the art do not break away from the essence and the spirit of the utility model; Can there be the various deformation scheme to realize the utility model; The above is merely the preferable feasible embodiment of the utility model; The interest field that is not so limits to the utility model, the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, and all is contained within the interest field of the utility model.
