Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
In order to make of the present inventionly to realize technological means, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, efficient terrestrial heat pump, comprise: air compression plant 18, condensation channel pipe 16, steam raising plant 15, pedestal 17, between described air compression plant 18 and pedestal, by slide rail, be connected, described air compression plant 18, condensation channel pipe number is two, described steam raising plant is helical structure, described steam raising plant both sides are provided with column evaporator, column evaporator is communicated in the various piece of steam raising plant 15, described air compression plant, condensation channel pipe, steam raising plant 15 is arranged on pedestal 17, condensation channel pipe 16 is arranged between air compression plant and steam raising plant 15, air compression plant 18 1 sides are provided with communicating valve 14, blast pipe 12, communicating valve 14 is connected by blast pipe 1 with air compression plant 18, condensation channel pipe 16 is connected in communicating valve 14 by isocon 2, communicating valve is connected in one end of steam raising plant 15 by condenser tube 3, the other end of steam raising plant 15 is provided with the first valve 5, the second valve 6, the upper end of steam raising plant 15 is connected in air compression plant 18 by the first evaporation tube 7, the middle part of steam raising plant 15 is connected in communicating valve 14 by the second evaporation tube 8, between steam raising plant 15 each assemblies, by the 3rd evaporation tube 9, connect, between condensation channel pipe 16 and communicating valve 14, be provided with wireway 10, isocon 11, between communicating valve 14 and each pipeline, by 360 ° of joints 13, be connected.
Operation principle of the present invention is: cryogenic gaseous cold-producing medium by compressor air suction valve through air compression plant, become high-temperature high-pressure refrigerant gas, then enter condensation channel pipe and transfer heat to cooling water generation heating hot water, refrigerant gas is condensed into normal temperature high voltage liquid refrigerant.From condenser liquid refrigerant drying filter out, remove moisture and impurity, the magnetic valve of flowing through becomes low-temp low-pressure liquid refrigerant and enters steam raising plant after expansion valve reducing pressure by regulating flow.In steam raising plant, the heat of low-temp low-pressure liquid refrigerant absorption cycle cold water constantly evaporates, and all becomes the overheated dry flue gas of low-temp low-pressure while arriving steam raising plant outlet, returns compressor air suction valve.Cold water after cooling reaches instructions for use, by steam raising plant cooling water outlet, is discharged.So iterative cycles, reaches heat supply or refrigeration object.
When the present invention works, compressor sucks refrigerant vapour from steam raising plant, by after refrigerant vapor compression, being pooled to same pipeline flow to oil eliminator and carries out Oil-gas Separation, the lubricating oil that separation obtains enters into oil strainer by oil pump later through oil cooler heat exchange, then flow to compressor and compressor through oil return pipe.In another loop, the pressure refrigerant vapour of discharging from oil eliminator enters condensation channel pipe, in condensation channel pipe, cold-producing medium is that cold water source carries out heat exchange with the oil cooler water pipeline coming heat exchange cooling medium once, cold-producing medium is condensed into the refrigerant liquid with certain pressure, and become thermal water source by condensation channel pipe water source heat exchange pipeline water source absorption heat out, flows out.
Above-mentioned refrigerant liquid enters after overexpansion valve, the refrigerant liquid that decrease temperature and pressure forms low-temp low-pressure enters evaporimeter, in steam raising plant, the cold-producing medium of low-temp low-pressure and refrigerating medium carry out heat exchange, cold-producing medium is boiling evaporated into refrigerant vapour after absorbing heat, refrigerating medium is emitted heat and temperature reduction, and refrigerant vapour cooled compressor suction after gas-liquid separator carries out gas-liquid separation again, enters next kind of refrigeration cycle.
In the present invention, condensation channel pipe and steam raising plant are the heat exchanger of plank frame, and its heat transfer coefficient is high, floor space is little, applying flexible, only need increase and decrease plate to change heat exchange area and can tackle different heat-exchanging states.Owing to adopting model, be two helical-lobe compressors that energy level is identical, share same oil piping system, be assemblied on same base and form helical-lobe compressor unit, its compact conformation, floor space is little, and investment and installation cost are low.The present invention also has the feature of operation flexible configuration, and two helical-lobe compressors can be standby each other, also can move simultaneously, if wherein a helical-lobe compressor breaks down, and on-line maintenance separately.In addition, the present invention is under sub-load, and by the energy level of the controller automatic equalization compressor in switch board, energy-saving effect highly significant, further reduces operating cost low.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Claimed scope of the present invention is defined by appending claims and equivalent thereof.
