- the high temperature cooling water is used as condensed cycling water is obviously different from the general used vapor condenser. The reason will be discussed in the following.
- the condensed cycling water used in the device is a water of normal temperature, which has a great temperature difference with water injected into the condenser 13 , and thus the vapor entering into the condenser 13 can be condensed quickly.
- the operation efficiency is high.
- the temperature difference between the condensed cycling water and the vapor is smaller and smaller, the range for heat conduction is smaller and smaller. This is disadvantageous to the condensation of the vapor and thus it will affect the operation efficiency of this device.
- the rear end of the main condenser system 1 is installed with an auxiliary condensing system 2 having a plurality of auxiliary Laffer nozzles 22 and a plurality of auxiliary condensers 21 .
- the auxiliary Laffer nozzles 22 and the auxiliary condensers 21 are indirectly serially connected.

More and more latent heat of the condensing water passing through each auxiliary condenser 21 is removed so that the vapor passing through the condenser 13 and the auxiliary condensers 21 can be condensed quickly. As a result, the object of removing latent heat quickly and increasing pumping speed is achieved.
- the advantage of the serial connected auxiliary Laffer nozzles 22 and auxiliary condensers 21 is that since the work of the auxiliary Laffer nozzles 22 in operation, the condenser 13 has the effect of condensation, but for the auxiliary Laffer nozzles, since the evaporation effect, the removing of the latent heat of the condensing water passing through the condenser 13 can be incremented.
- the auxiliary condensers 21 have the effect of condensation, but due to the work of the auxiliary Laffer nozzles 22 , it has the effect of evaporation.
- the present invention uses cycling water of normal temperature for condensing the vapor passing through the condenser, the efficiency of condensing is only reduced slightly because of the serial connected auxiliary Laffer nozzles 22 and auxiliary condensers 21 . If required in some case, the air inlets and the injecting outlets of the auxiliary Laffer nozzles 22 and the condensers 21 can be serially connected to work by nozzles of multiple stages so as to increase the pumping speed. Thus the pump effect is increased further. Since the main requirement is an optimum balance point of the power consumption and work, the content will not be described further.
- the three phase control valve 34 behind the vapor cooler 33 in front of the vapor container 35 can be changed to have output end from the lower end (referring to FIG. 6) and the controls A in the vapor output control pipes are closed, but the control valve A 1 below the vapor cooler 33 is opened so that the vapor boiler 31 works continuously. Then, the vapor flows into the vapor coil pipe 512 of the cycling condensing water storage tank 51 by the pipes below the three phase control valve 34 . By the vapor coil pipe 512 , the traveling length of the vapor is increased so as to reduce the speed of the vapor for preventing the vapor to vent out.
- the vapor fills into the cycling condensing water storage tank 51 so as to increase the water in the cycling condensing water storage tank 51 to a preset value. Then the vapor is sent to the hot water adjusting tank 52 through the hot water supplying pump 521 . This operation way is used when only hot water is required. Since only the hot water supplying pump 521 is opened and other pump is stopped, and thereby, the power is saved.
- the auxiliary water system 6 of the present invention is installed with a filter 62 and an auxiliary water boost filtering pump 631 (referring to FIG. 5).
- the level detector H above the auxiliary water tank 61 emits signals to actuate the auxiliary water boost filtering pump 631 so that the water in the normal water tank 63 is boosted and then sent through the filter 62 and then enters into the auxiliary water tank 61 until the level in the auxiliary water tank 61 is achieved to a preset high level.
- the water supply of the normal water tank 63 is from a running water source W.
- a reverse flow pump 611 is formed between the auxiliary water tank 61 and the filter 62 . If the filter 62 is blocked so that the pressure of the water flowing therethrough is increased and thus the quality of water is deteriorated or the water flow is reduced. Then control valves A 2 and A 3 will be closed and the reverse flow pump 611 and the reverse flow outlet control valve A 4 is opened so that the dirty objects on the filter 62 can be removed to be drained to the waster water draining system W 2 . After the reverse flow process is completed. The reverse flow pump 611 and the control valve A 4 are closed. Then the control valves A 2 and A 3 in the auxiliary water system 6 are opened so that the filter 62 completes the whole standby process. This reverse flow process can be processed manually.

- Referring to FIG. 1, the flow diagram of the present invention is illustrated and further referring to other drawings of the present invention. It is known that the present invention is formed by a
main condenser system 1, anauxiliary condenser 2, anheat supply system 3, a icewater supply system 4, a hotwater supply system 5, and anauxiliary water system 6. Themain condenser system 1 is formed by anevaporator 12, acondenser 13, and a plurality ofLaffer nozzles 11 between theevaporator 12 and thecondenser 13. Thesuction end 111 of the nozzle is connected to the evaporator 12 (referring to FIG. 2). Theoutlet end 113 thereof is connected to be upon thecondenser 13. Themiddle throat 112 is smaller the gap between the two ends. The pipe of theevaporator 12 is installed with an pressure meter B and a pressure transducer C. Theauxiliary condensing system 2 is formed by a plurality ofauxiliary condensers 21, a plurality ofauxiliary Laffer nozzles 11, andmufflers 23. Theauxiliary Laffer nozzles 22 and theauxiliary condensers 21 are serially connected indirectly and a distal end thereof is connected to amuffler 23. Theheat supply system 3 is formed by a vapor boiler 31, anelectromagnetic valve 32, avapor cooler 33, a threephase control valve 34, and avapor container 35. Theelectromagnetic valve 32 serves to control the flowing of the vapor boiler 31. Thevapor cooler 33 serves to separate the condensing water from vapor and then guides the water to a condensing watercycling storage tank 51. The threephase control valve 34 serves for controlling the flow of vapor according to the use of the system (making ice and hot water at the same time or only making hot water). The icewater supply system 4 is formed by a refrigeratingwater storage tank 41, an ice water adjustingtank 42 and aheat exchanger 43. A temperature monitor D, a temperature signal transmitter E, and a level detecting controller F are installed in each of the ice water adjustingtank 42 and the refrigeratingwater storage tank 41. Thereby, the refrigeratingwater cycling pumps 411 between the refrigeratingwater storage tank 41 and theheat exchange 43 and the ice water heatexchange cycling pump 421 between the cooling water adjustingtank 42 and theheat exchanger 43 can be opened and closed automatically. There are two refrigeratingwater cycling pumps 411 which are arranged in parallel. One is used as a standby pump for updating as the other one is damaged. The refrigeratingwater cycling pump 411 is installed with a manometer G for measuring pressures. The hotwater supply system 5 is formed by a cycling condensingwater storage tank 51 and hot water adjustingtank 52. The cycling condensingwater storage tank 51 is installed with a temperature monitor D, a temperature signal transmitter E, a level detecting controller F, and avapor coil pipe 512. The hotwater adjusting tank 52 has a level control valve H. By above components, the hotwater supplying pump 521 between the condensingwater cycling pump 511 and the hotwater supplying pump 521 can open and close automatically. Each of the condensingwater cycling pump 511 and hotwater supplying pump 521 has two set which are arranged in parallel. One is used as a standby pump for updating as the other one is damaged. The condensingwater cycling pump 511 and hotwater supplying pump 521 are installed with a manometer G for measuring pressures. Theauxiliary water system 6 is formed by an auxiliary water tank, 61, awater storage tank 63 and afilter 62. Theauxiliary water tank 61 has a level detecting controller F. Thewater storage tank 63 is installed with a level control valve H. By above components, the system can acquire auxiliary water at any time for being used by detecting and control elements, such as the pressure meter B, pressure transducer C, temperature monitor D, temperature signal transmitter E, level detecting controller F, level control valve H, manometer G, control valves A, A1 to A4 and check valve N. - The vapor injecting ice and hot generating device may produce ice water and hot water at the same time. The whole system may be divided into an ice water manufacturing portion and a hot water manufacturing portion.
- For the ice water manufacturing portion, in the operation starts, water of normal temperature is filled into a refrigerating
water storage tank 41 of a icewater supply system 4 to a preset level. Then the refrigeratingwater cycling pump 411 is actuated. When the cooled water of normal temperature passes through theheat exchanger 43 and theevaporator 12 of themain condenser system 1 and then returns to the refrigeratingwater storage tank 41 so as to form a cycling water flow (referring to FIG. 3). Next, the vapor boiler 31 is actuated, so that the vapor boiler 31 of the water supply system WS may manufacture vapor until the vapor pressure in the vapor boiler 31 until 0.9 Mpa so as to actuate theelectromagnetic valve 32. Then vapor passes through thevapor cooler 33, threephase control valve 34,vapor container 35 and then enters into the pipes. The condensed water in this section is fed back to the system through thevapor cooler 33. Thereby, the efficiency of vapor can be sustained. Thereby, vapor passes through the each vapor pipes, thevapor container 35 and the control valve A and then enters into theLaffer nozzle 11 and theauxiliary Laffer nozzle 22. When vapor passes through thethroat 112 of the nozzle, since the diameter of the pipe reduced, the vapor is compressed. When the vapor passes through thethroat 112 of the nozzle, the pipe becomes larger abruptly. As a result, the vapor flow expands rapidly to be near sound speed. As a result, thesuction end 111 of theLaffer nozzle 11 has a negative pressure of about 100 Torr (about 13 Kpa). Thereby, theevaporator 12 connected to the air inlet channel of theLaffer nozzle 11 has the effect of sucking air. As a result, the latent heat of the refrigerating water cycling flow can be removed rapidly. Thus, the refrigerating water cycling flow is evaporated. Then the water temperature of the refrigerating water cycling flow is reduced continuously. This process continues so that the refrigerating water cycling flow achieves a temperature of about 5° C. or more lower temperature (the primary object is to manufacture ice water of 5° C. and hot water, and thus, the temperature monitor D and the temperature signal transmitter E of the icewater supply system 4 is adjusted to 5° C. which is a preset temperature of ice water). After the refrigerating water cycling flow has achieved the preset temperature, the ice waterheat exchange cycle 421 is actuated so that the water in the icewater adjusting tank 42 is transferred. The water passes through theheat exchange 43 to heat exchange with the refrigerating water cycling flow until the water in the icewater adjusting tank 42 is reduced to a preset temperature. If the water in the icewater adjusting tank 42 is consumed, the level detecting controller F will open or close the level control valve H so as to control the inlet flow of the water of theauxiliary water system 6. - In the whole ice water manufacturing system, monitors and controllers are used, and therefore, no operators are required. The process can be performed automatically. If the ice water in the down flow is not used. The temperature of the/refrigerating water cycling flow is reduced to a preset critical point, the vapor boiler31 will stop automatically, until the refrigerating water cycling flow increases to a preset value so that the boiler can be refueled for saving fuels. Moreover, if the ice water in the down stream ice water heat
exchange cycling pump 421 has stopped, the refrigeratingwater cycling pump 411 also stopped. However, a time period is required from starting up to the temperature of the refrigerating water cycling flow achieving to a preset value (a default temperature). Thereby, each cycling pump of the icewater supply system 4 or the vapor boiler 31 has a buffer actuating and stop times. Whether it is required to operate the vapor boiler 31 is determined by individual condition. - The manufacturing of hot water will be described hereinafter. Before actuating the hot
water supply system 5, cycling condensingwater storage tank 51 is filled with water of normal temperature. After system is actuated, the condensingwater cycling pump 511 actuates, the water of normal temperature in the cycling condensingwater storage tank 51 is sent to thecondenser 13 of themain condenser system 1 and eachauxiliary condensers 21 in the condenser system 2 (referring to FIG. 4). Thereby, vapor from theLaffer nozzle 11 to thecondenser 13 and theauxiliary condensers 21 from theauxiliary Laffer nozzles 22 are condensed. Since in the condensed water in the process of condensing recycled continuously, the temperature of condensed water cycling flow increased gradually due to the high temperature from the vapor to a value of 60° C. or a preset temperature (the temperature is controlled by the temperature monitor D and temperature signal transmitter E in the cycling condensing water storage tank 51). Then, the hot water is sent to the hotwater supplying pump 521 to the hotwater adjusting tank 52 for use until the level in the hotwater adjusting tank 52 achieves a preset value. If a large amount of hot water in the down stream is required due to evaporation and thus a large amount of hot water is sent out, the level of the cycling condensingwater storage tank 51 is reduced to a preset value, the level control valve H in the cycling condensingwater storage tank 51 is opened, and water of normal temperature is filled through theauxiliary water system 6. - The way for condensing the vapor injected into the
condenser 13 is to use the condensing cycling water, it is identical to general used vapor condenser, but the difference therebetween is that in the present invention, a rear end of themain condenser system 1 is installed with a plurality of parallelauxiliary Laffer nozzle 11, and a plurality of serial connectedauxiliary condensers 21, causing the system to sustain a high operation efficiency. The high temperature cooling water is used as condensed cycling water is obviously different from the general used vapor condenser. The reason will be discussed in the following. If in the present invention, only themain condenser system 1 is installed without theauxiliary condensers 21 andauxiliary Laffer nozzles 22, although initially, since the condensed cycling water used in the device is a water of normal temperature, which has a great temperature difference with water injected into thecondenser 13, and thus the vapor entering into thecondenser 13 can be condensed quickly. The operation efficiency is high. With the increasing of the condensed cycling water, the temperature difference between the condensed cycling water and the vapor is smaller and smaller, the range for heat conduction is smaller and smaller. This is disadvantageous to the condensation of the vapor and thus it will affect the operation efficiency of this device. - Therefore, the rear end of the
main condenser system 1 is installed with anauxiliary condensing system 2 having a plurality ofauxiliary Laffer nozzles 22 and a plurality ofauxiliary condensers 21. Theauxiliary Laffer nozzles 22 and theauxiliary condensers 21 are indirectly serially connected. In a continuous operation, since when vapor flows into themain condenser system 1, it is also transferred to theauxiliary condensing system 2. The suction end of theauxiliary condensing system 2 also pump the air in thecondenser 13 of themain condenser system 1. As a result, a large amount of latent heat of the condensed cycling water passes through thecondenser 13 of themain condenser system 1 is removed greatly. The latent heat enters into theauxiliary condensing system 2. By the transformation of the plurality ofauxiliary Laffer nozzles 22 and theauxiliary condensers 21, the latent heat is finally released to air by theauxiliary condensers 21 at the distal end. Moreover, since theauxiliary Laffer nozzles 22 and theauxiliary condensers 21 are arranged as a series connection, the speed of the vapor and water enters into theauxiliary Laffer nozzles 22 and theauxiliary condensers 21 are increased gradually. The pumping speed of eachauxiliary condenser 21 is also increased gradually to achieve 40 Torr. More and more latent heat of the condensing water passing through eachauxiliary condenser 21 is removed so that the vapor passing through thecondenser 13 and theauxiliary condensers 21 can be condensed quickly. As a result, the object of removing latent heat quickly and increasing pumping speed is achieved. - The advantage of the serial connected
auxiliary Laffer nozzles 22 andauxiliary condensers 21 is that since the work of theauxiliary Laffer nozzles 22 in operation, thecondenser 13 has the effect of condensation, but for the auxiliary Laffer nozzles, since the evaporation effect, the removing of the latent heat of the condensing water passing through thecondenser 13 can be incremented. Likely, theauxiliary condensers 21 have the effect of condensation, but due to the work of theauxiliary Laffer nozzles 22, it has the effect of evaporation. Although the present invention uses cycling water of normal temperature for condensing the vapor passing through the condenser, the efficiency of condensing is only reduced slightly because of the serial connectedauxiliary Laffer nozzles 22 andauxiliary condensers 21. If required in some case, the air inlets and the injecting outlets of theauxiliary Laffer nozzles 22 and thecondensers 21 can be serially connected to work by nozzles of multiple stages so as to increase the pumping speed. Thus the pump effect is increased further. Since the main requirement is an optimum balance point of the power consumption and work, the content will not be described further. - If in a long time period, only hot water is required, but no ice water is required, the three
phase control valve 34 behind thevapor cooler 33 in front of thevapor container 35 can be changed to have output end from the lower end (referring to FIG. 6) and the controls A in the vapor output control pipes are closed, but the control valve A1 below thevapor cooler 33 is opened so that the vapor boiler 31 works continuously. Then, the vapor flows into thevapor coil pipe 512 of the cycling condensingwater storage tank 51 by the pipes below the threephase control valve 34. By thevapor coil pipe 512, the traveling length of the vapor is increased so as to reduce the speed of the vapor for preventing the vapor to vent out. Then, the vapor fills into the cycling condensingwater storage tank 51 so as to increase the water in the cycling condensingwater storage tank 51 to a preset value. Then the vapor is sent to the hotwater adjusting tank 52 through the hotwater supplying pump 521. This operation way is used when only hot water is required. Since only the hotwater supplying pump 521 is opened and other pump is stopped, and thereby, the power is saved. - To avoid the interference of quality of water to some devices, the
auxiliary water system 6 of the present invention is installed with afilter 62 and an auxiliary water boost filtering pump 631 (referring to FIG. 5). In operation, when level of theauxiliary water tank 61 is descended to a preset point. The level detector H above theauxiliary water tank 61 emits signals to actuate the auxiliary waterboost filtering pump 631 so that the water in thenormal water tank 63 is boosted and then sent through thefilter 62 and then enters into theauxiliary water tank 61 until the level in theauxiliary water tank 61 is achieved to a preset high level. The water supply of thenormal water tank 63 is from a running water source W. - Since the water goes through the processes of deposition, filtering, and killing bacteria. Then the water is sent to each user for use. However, some undesired elements, such as dusts, are still in the water. In general, a filter is used to filter the water before it is drunk or the water is boiled. However, in above example, a
filter 62 is used, but it is possible that thefilter 62 will be blocked by undesired objects so that the quality of water is deteriorated or the water flow is reduced. - To avoid this effect, in the present invention, a
reverse flow pump 611 is formed between theauxiliary water tank 61 and thefilter 62. If thefilter 62 is blocked so that the pressure of the water flowing therethrough is increased and thus the quality of water is deteriorated or the water flow is reduced. Then control valves A2 and A3 will be closed and thereverse flow pump 611 and the reverse flow outlet control valve A4 is opened so that the dirty objects on thefilter 62 can be removed to be drained to the waster water draining system W2. After the reverse flow process is completed. Thereverse flow pump 611 and the control valve A4 are closed. Then the control valves A2 and A3 in theauxiliary water system 6 are opened so that thefilter 62 completes the whole standby process. This reverse flow process can be processed manually. - The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
