Accompanying drawing explanation
Fig. 1 is the system construction drawing of the different poly-state heat utilization system of solar energy.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.As shown in Figure 1, the different poly-state heat utilization system of a kind of solar energy, comprising main evaporator 1, compressor 2 and the condenser 3 by connecting for the transmission pipeline 4 of the heat transfer medium that circulates, between the outlet and the import of main evaporator 1 of condenser 3, being provided with main restricting element 8.Main evaporator 1 is solar still.
Auxiliary restricting element 6 and the auxiliary evaporimeter 5 of series connection mutually is also parallel with at the two ends of main restricting element 8.Auxiliary evaporimeter 5 is air energy evaporimeter.Auxiliary restricting element 6 is located between the outlet of condenser 3 and the import of auxiliary evaporimeter 5; Main restricting element 8 adopts electric expansion valve, and auxiliary restricting element 6 adopts heating power expansion valve, and the circulation of main restricting element 8 and adjustable range are greater than circulation and the adjustable range of auxiliary restricting element 6.The transmission pipeline 4 in condenser 3 exit is provided with fluid reservoir 7, and the feed tube outlet of fluid reservoir 7 is positioned at the top of tank body, and drain pipe import is positioned at the bottom of tank body.
The embodiment course of work of the present utility model is as follows: the liquid state becoming high-temperature low-pressure after the gaseous heat-transfer medium of the HTHP of compressor 4 outflow enters condenser 3 heat release.The auxiliary restricting element 6 be connected with condenser 3 is in normally open, with the minimal circulation amount of heat transfer medium in guarantee system; The heat transfer medium that auxiliary restricting element 6 flows out enters the gas-liquid mixed state heat transfer medium becoming low-temp low-pressure after auxiliary evaporimeter 5 absorbs heat.The main restricting element be connected with condenser 3 regulates the flow of heat transfer medium according to the change of external environment is interior on a large scale: (heat-transfer medium temperature supposing to flow out main evaporator is T1, the heat-transfer medium temperature flowing into main evaporator is T2,) when ambient temperature is lower, the heat transfer medium amount needed reduces, and will cause T
1-T
2reduce, the aperture of main restricting element 8 reduces thereupon, to provide suitable heat transfer medium evaporating space and pressure, unnecessary heat transfer medium is temporarily stored in fluid reservoir 7, fluid reservoir adopts the structure of high in and low out, and feed tube is positioned at the top of tank body, and drain pipe is positioned at the bottom of tank body.When ambient temperature is higher, the heat transfer medium amount of needs increases, now T
1-T
