Background technology

Solar energy is inexhaustible, the nexhaustible energy.Directly utilize solar energy to collect, store, utilize again and reach refrigeration, heating effect, not only can save a large amount of electric energy or chemical energy that adopt usually, have important environment protection significance simultaneously again.

Summary of the invention

The utility model provides a kind of novel solar refrigeration heating combined equipment.The solar energy of collecting can be passed through carrier---cold-producing medium directly freezes, heats, and need not to change by electric energy.

The utlity model has thermal energy storage device, in order to the insufficient time of sunlight, as overcast and rainy, night equal time discharge utilization automatically.

Principle of the present utility model can be applicable to air-conditioner, bathing, refrigerator, freezer and other refrigeration, heating.

The utility model is made of jointly thermal-arrest, energy storage, releasing device and circulating line.Wherein, heat collector is used to receive solar radiation, is made of the copper tube that is installed in the glass tube with vacuum.Be filled with cold-producing medium in the copper tube, under solar irradiation, the copper tube temperature raises, its inner refrigerant heats boiling, volumetric expansion, temperature, pressure all increase, and are diffused in the radiator coil tube of the energy storage device that is connected with heat collector, energy storage liquid distribute heat in energy storage device rises the energy storage liquid temp and puts aside heat.Heat collector also can adopt in the known solar energy equipment flat plate collector commonly used, except that structure slightly the difference its principle and above-mentioned vacuum glass tube heat collector basic identical, need not give unnecessary details.Energy storage device is the container with heat-insulating property, is full of energy storage liquid, and the liquid lower as set points such as grease, alcohols is provided with radiator coil tube in the energy storage device, and the one end links to each other with the copper tube of heat collector, and the other end then is connected with releasing device.Disconnected thermal phenomenon in order to prevent that long-time sunlight deficiency from may cause also can be provided with electric heater in the energy storage device, and available electrical energy is replenished in case of necessity.Releasing device is used for the heat from radiating tube is applied in refrigeration, the heating equipment.Comprising two pipelines, article one, pipeline will carry in the cold-producing medium importing heating equipment of heat, another pipeline is by device for drying and filtering, capillary, make the warm refrigerant drying that flows through in the energy storage device filter back spray evaporation cooling rapidly from capillary, again with refrigeration form refrigerant conveying in refrigeration plant.Article two, pipeline is equipped with reversal valve or stop valve, is used for control refrigeration or heating capacity.Circulating line is a series of pipelines that check valve is housed, and it will lead back heat collector at the cold-producing medium after refrigeration, the heating equipment acting makes it enter new round circulation.

In view of the above, the utility model is the energy with the solar radiation, has realized the purpose of using solar energy to freeze, heat.

Below in conjunction with two kinds of embodiment shown in the drawings, describe structure of the present utility model in detail.

The specific embodiment

According to Fig. 1, a kind of embodiment of the present utility model is made of jointly heat collector 1, energy storage device 2, releasing device 3 and circulating line 4.Wherein, heat collector 1 is used to receive solar radiation, is made of the thermal-arrest copper tube 12 (representing with solid black lines among the figure) of series installation in glass tube with vacuum 11.Be filled with cold-producing medium in the copper tube 12, under solar irradiation, the copper tube temperature raises, its inner refrigerant heats boiling, volumetric expansion, temperature, pressure all increase, and are diffused in the radiator coil tube 26 of the energy storage device 2 that is connected with heat collector 1, energy storage liquid 23 distribute heats in energy storage device 2 rise energy storage liquid 23 temperature that are made of grease or alcohols material and put aside heat.Shell 21 and inner bag 22 that energy storage device 2 is made by metal or macromolecular material constitute, and are evacuated or filled heat insulating material between shell 21 and the inner bag 22, as polyurethane.One end of radiator coil tube 26 links to each other with the copper tube 12 of heat collector 1, and the other end then is connected with releasing device 3.Disconnected thermal phenomenon in order to prevent that long-time sunlight deficiency from may cause also can be provided with electric heater 25 in the energy storage device 2, and available electrical energy is replenished in case of necessity.Releasing device 3 is used for the heat from radiating tube is applied in refrigeration, the heating equipment.It has shell 31, radiating tube enters and wherein is divided into two, be cut off valve 32 controls respectively by blocking, wherein a pipeline drying device 33 enters capillary evaporation pipe 34, send low-temperature refrigerant to

outlet

36,35 in another pipeline is directly sent high temperature refrigerant to outlet 36, and two pipelines can be respectively applied for refrigeration or heating equipment (not shown).Cold-producing medium after refrigeration or heating equipment acting refluxes by the circulating line 4 (representing with hollow lines among the figure) that check valve 41 is housed, and leads back heat collector 1 and makes it enter new round circulation.
