Detailed description of the invention
In conjunction with a kind of directly-heated type Teat pump boiler shown in Fig. 1-6, including compressor 1.The outlet of compressor 1 is connected with the outer tube 4 of double-tube heat exchanger 2, outer tube 4 end of described double-tube heat exchanger 2 is connected with electric expansion valve 5, heat transferring medium flows in outer tube 4, described electric expansion valve 5 is connected with vaporizer 6, described vaporizer 6 is connected with gas-liquid separator 7, and described gas-liquid separator 7 is connected with the import of compressor 1.
The outer tube 4 of described double-tube heat exchanger 2 along the flow direction of heat transferring medium be divided into uniformly multistage, described heat transferring medium can be nitrogen, ammonia or other play the gas of phase same-action.The outlet of described compressor 1 is connected with each section of outer tube 4 respectively by flow divider 10, is respectively provided with check valve 8 between adjacent two sections of described outer tube 4, and check valve 8 avoids heat transferring medium backflow, it is ensured that the stability of heat exchange.The interior pipe 3 of described double-tube heat exchanger 2 is connected with tap water pipe network and storage tank 9 respectively, and cold water heat transferring medium in the process flowing through interior pipe 3 and in outer tube 4 carries out heat exchange.Hot water storage after heat exchange is in storage tank 9.
In the middle of the use procedure of the present invention, first heat transferring medium is compressed into high temperature and high pressure gas by compressor 1, now heat transferring medium respectively enters each section of outer tube 4 by flow divider 10 and pipeline, water from tap water pipe network flows through from interior pipe 3, by carrying out heat exchange with heat transferring medium in the process of interior pipe 3.Water after heat exchange flows in storage tank 9 stand-by through pipeline.After heat transferring medium and water heat exchange, temperature reduces, and the heat transferring medium after temperature reduction becomes liquid under the continuous action of pressure.After electric expansion valve 5, heat transferring medium enters vaporizer 6, in this process, heat transferring medium gasification heat absorption, then enter back in compressor 1 and again go into circulation.Due to the fact that outer tube 4 is divided into multistage, and the heat transferring medium of high temperature carries out heat exchange respectively with each section, the heat transferring medium entering each section of outer tube 4 is all the high-temperature gas just discharged from compressor 1, and therefore the water temperature difference in heat transferring medium and interior pipe 3 is bigger.And traditional heat exchange mode, due in the process that heat transferring medium flows in outer tube 4 along with thermal loss, therefore temperature is more and more lower, and the temperature difference at the rear of outer tube 4, heat transferring medium and water will be greatly reduced.Due to rate of heat transfer=driving force of heat transfer (temperature difference)/heat transfer resistance, temperature difference is more high also more fast with regard to rate of heat transfer.So the heat exchange mode of the present invention is compared with traditional heat exchange mode, faster more efficient.Described outer tube 4 can be divided into two sections, three sections, four sections even more, certain outer tube 4 hop count heat transfer rate more at most is more fast, is divided into three sections just can reach better effects under normal circumstances.
Better way is, the heat transferring medium in described outer tube 4 flows to contrary with the current direction in interior pipe 3, say, that the port of export of outer tube 4 is the entrance point of interior pipe 3.So, in this way it is ensured that in the process of heat exchange, heat transferring medium remains at more stable temperature difference with the water in interior pipe 3, thus further increasing the stability of the present invention.
