Description
Technical field
The invention belongs to technical field of solar, relate in particular to solar heat pump collecting system.
Background technology
Because energy-conservation and environmental protection, heliotechnics is widely applied in daily life.For example heliotechnics is applied in and in field of water heaters, has just formed solar water heater.
Common solar water heater comprises heat collector and water tank, in heat collector, collecting plate receives solar energy, temperature raises, and the working media that circulates in collecting plate of heating, working media after temperature raises flows through water tank by pipeline, carries out heat exchange, with the water in water tank in the process of heat exchange, the temperature of the water in water tank raises, and the temperature of working media reduces; Working media after temperature reduces is flowed back in heat collector and is continued to be heated by pipeline again; Circulate with this.
But the precondition that solar water heater of the prior art can normally be worked is above: the temperature of collecting plate exceeds to a certain degree than the temperature of water in indoor water tank.If the temperature of water is similar in the temperature of collecting plate and indoor water tank, or the temperature of more serious collecting plate is lower than the temperature of water in indoor water tank, above-described solar water heater cannot normally be worked, because the working media in collecting plate can not can be transferred to the water in water tank again by the interior of collecting plate absorption.And this situation is not often to occur the particularly preferred period at illumination condition conventionally, for example, when dusk or cloudy day, and this time, collecting plate still absorbed solar energy conventionally, but but cannot will in this part, can pass to the water in water tank, the solar energy utilization ratio that causes whole solar water heater is not very high.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of solar heat pump collecting system, can improve the utilization ratio of solar energy.
For achieving the above object, one embodiment of the present of invention provide a kind of solar heat pump collecting system, comprise water tank and heat collector, described heat collector comprises a collecting plate, is provided with the first working media circulation passage and the second working media circulation passage in described collecting plate;
In described water tank, be provided with condenser and the first working media heat exchanger;
Also comprise the compressor that is arranged on water tank outside, described compressor communicates with the second working media circulation passage in condenser and collecting plate in water tank by pipeline, composition heat pump cycle loop;
Also comprise the water pump that is arranged on water tank outside, described water pump is connected with the first working media circulation passage in the first working media heat exchanger and collecting plate plate in water tank by pipeline, composition solar heat exchange cycles loop.
Together with the solar heat pump collecting system that the embodiment of the present invention provides has been incorporated into two kinds of modes that the water in water tank is heated of solar energy and heat pump, in collecting plate, be provided with again the circulation passage of two kinds of working medias for the mode of these two kinds of thermal cycles simultaneously simultaneously.But but illumination condition is not very good collecting plate still can absorb solar energy time, although the temperature of collecting plate is not too high with respect to the temperature of Water in Water Tanks, but can be by the forced circulation of hot plate, in on collecting plate, can force to be carried in water tank, and then the utilization ratio of the solar energy of raising collecting plate absorption, therefore in the present invention, the thermal cycle of heat pump and the thermal cycle of solar energy have reached organic cooperation.

Detailed description of the invention
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is the cutaway view of solar heat pump collecting system provided by the invention, as shown in Figure 1, comprises water tank 2 and heat collector 1 in this overall system.Heat collector 1 comprises collecting plate, is provided with the first working media circulation passage and the second working media circulation passage in collecting plate.
In water tank 2, be provided with condenser 6 and the first working media heat exchanger 5.
At water tank 2 outer setting compressors 3, this compressor 3 is identical with the second working media circulation passage arranging in condenser 6 in water tank 2 and collecting plate with 46 by pipeline 41,44,45, composition heat pump cycle loop.This heat pump cycle loop, for by the mode of heat pump, is carried to the heat of outside collecting plate in water tank 2.
In water tank outside, water pump 9 is also set, water pump is connected with the first working media circulation passage in the first working media heat exchanger 5 and collecting plate in water tank by pipeline 47,42 and 43, composition solar heat exchange cycles loop.The solar energy energy transform into heat energy of this solar heat exchange cycles loop for collecting plate is absorbed, and be carried in water tank 2.
In the present invention, the second working media can be freon, and the first working media can be heat exchange circulation medium conventional in solar water heater.
As can be seen here, together with the solar heat pump collecting system that the embodiment of the present invention provides has been incorporated into two kinds of modes that the water in water tank is heated of solar energy and heat pump, the circulation that simultaneously mode for these two kinds of thermal cycles is provided with two kinds of working medias simultaneously again in collecting plate all.But but illumination condition is not very good collecting plate still can absorb solar energy time, although the temperature of collecting plate is not too high with respect to the temperature of Water in Water Tanks, but can be by the forced circulation of hot plate, in on collecting plate, can force to be carried in water tank, and then the utilization ratio of the solar energy of raising collecting plate absorption, therefore in the present invention, the thermal cycle of heat pump and the thermal cycle of solar energy have reached organic cooperation.
Below concrete structure of the present invention is elaborated.
