Invention: [Technical field of invention] Shi ^ Ming is about the pressure difference control of the bypass pipe to control the energy-saving ice water system 'special ϊ ΐΐ ΐΐ ΐΐ 冰 冰 冰 冰 冰 — — — — — — — — — — — 次 次 次 次 次Two 主机 host and pump operation efficiency 'to make ice water system - secondary and secondary side, _ = and water supply _ _ ice water temperature does not interfere with each other, improve energy (', its rate, reduce carbon monoxide and heat emissions The environmental damage of the bypass pipe pressure difference control energy-saving ice water system. [Prior Art], see the secondary bypass pipe ice water system, as shown in the first figure, it will be back to the water The higher temperature ice water on the side passes through the control valve 2 „ into the ice water main unit 1 hair strip 1 Q, and the high temperature ice water absorbs the cold energy generated by the evaporator 1 to become low temperature ice water, and then passes through the balance valve* a flows into the secondary circulation pump 7, and then pumps the ice water through the proportional control device 5, π into the equipment load 6 after the cold energy of the supply device load 6, and then returns to the balance valve 4 b Circulating pump 3 to form a device duty cycle 13; however, the above two In the secondary ice water system, when the flow rate and pressure of one cycle 11 are greater than ^ cycle i 2 , excess high-pressure low-temperature ice water that has not flowed into the secondary side of the equipment load cycle 13 flows to the return water side of the ice water system via the bypass pipe 8; When the flow rate and pressure of the secondary cycle 12 are greater than the primary cycle 丄 '1, the excess high-pressure high-temperature ice water that has not flowed into the equipment load cycle 13 - the secondary side flows to the water supply side of the ice water system via the bypass pipe 8; 8 The high-pressure side ice water is bypassed to the low-pressure side, so that the pressure of one cycle 11 and the second cycle is compatible. However, in the above-mentioned secondary ice water system, when the flow rate and pressure of one cycle are greater than the second cycle At 12 o'clock, no inflow into the equipment load cycle 1 3 secondary side excess high pressure low temperature ice water flows to the backwater side of the ice water system via the bypass pipe 8, and the high temperature ice water is cooled by the high temperature ice water of the return water side, causing the high temperature ice water to cool down, resulting in Ice 200912224 f Circulating pump 3 idling and a large amount of energy consumption; when the pressure of the secondary circulation cycle 1 is greater than one cycle 11 , the water supply side of the water supply side of the equipment load system does not flow into the high temperature ice water flowing through the bypass pipe 8 to the ice water , after mixing with low temperature ice water The water supply side low temperature ice water temperature rise·f 6 and the secondary circulation pump 7 increase the operating power, causing huge sighs and idling and electricity expenses. The second bypass pipe ice water system that Mingren sees has the above shortcomings. , issued [Faday Hai some shortcomings research and improvement, finally have this month generated. Ο, ηί! 明 ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ , Benbu, also has the purpose of ample energy supply. Ice water Ming ί: The provision of a kind of bypass pipe pressure difference control energy saving hunting - the pressure difference between the secondary and the second cycle is equal to i When J sets the force setting value, the two cycles of ice water temperature do not dry each other. If the difference between the two forces is not equal to (greater than or less than) the reaction force of the differential control device, the two cycles are compatible with each other. The invention achieves the above-mentioned purpose and effect 'the technical hand that adopts it:--the ice water host' contains an evaporator inside, which can be used for the high-temperature ice and water production to generate the warm ice when operating with the Wei (four) ice water host. Water '·- equipment training, test the second: domain county Puzhi ice water ^ ^ low can absorb the cold energy of the evaporator ice water flowing through the ice water host, to obtain, cold source; once a cycle pump 'It can be ice water, it can be passed through the electric 卞β water main unit, the evaporator in the ice water main unit, the balance 阙, the bypass tube and the difference control device, and the E7-secondary circulation pump is formed—the second cycle”^ ring pumping, The ice water can be moved backwards to form a secondary circulation through the aforementioned proportional control shield device load, balance room, bypass pipe, and money differential control after the flow pump is formed; - the bypass pipe can be bypassed once. [-People cycle, the higher pressure side of the ice water flows to the lower pressure side, so that one cycle J - 200912224 factory ^ cycle pressure compatible; one or several constant pressure difference control devices, control - times ^ sorrow and two times The ring pressure difference is equal to the set value of the constant difference control device; the balance valve is disposed at the effluent host and the load outflow end of the device, Adjusting the flow of each J-manifold '·-Electrical switch, set in the flow or outflow end of the ice water to start or shut down the ice water pipe with the ice water host; a proportional control ΐΓΐίΪ贞 current carrying person or outflow end 'cooperate Let (4) load capacity be adjusted in plural ratio ~ into the equipment load ice water; once cycle, once German production i: S ice 衡 衡 3 its J over electric valve, ice water host, ice water host ^ Ο Ο ^^ Sub-July Ring; -Secondary Cycle, Secondary Cycle "Water" makes it pass the aforementioned proportional control device, equipment load device, and the secondary circulation pump can enter the ice water and cold ice water respectively through the balance:: The control device, the equipment load, and the balance valve flow back to the % pump to form a device load cycle. As for the detailed structure, application principle, and function of the present invention, the following detailed description can be used to make a complete solution, :, Embodiments: main two = lost; work (2) tube ice water system, the second picture is shown in the embodiment of the invention 谧 not (four) ί 2 (4) the application of the main changes include: ice water host system sorrow 5, 5 and Backup load 6, secondary circulation gather sewing control device 9, evaporator i Q, - pepper m Wei 12, miscellaneous load cycle 13, 13 and so on, when the cycle = 200912224 i fixed, :: shield: 1: 2 pressure difference is equal to the constant pressure difference control device 9 pressure Gils touch pump 3 can pass ice water through The electric width is 2°, that is, the 纟f', and the hair f 1 〇, so as to absorb the cold ice water which is used for the operation of the chilled water host 1 can be respectively passed through the balancing valve 4 a and then the second and second 〇 That is, the proportional control of the person is set to 5, the load of the equipment is 6, the balance valve 4 is formed by the ring pump 3, and the surface of the ring is 1 3; the weaving is known, the middle of the cycle is 1 1 and the second cycle is 1 2 #不ί !^ is greater than or less than the pressure Γ set by the constant pressure difference control device 9 and the U' 丨疋 differential pressure control device 9 is turned on at a plurality of ratios, which have the following different modes in actual operation: /i Ϋί? Ring 11 pressure is greater than the second cycle 12, one cycle ii ? Part of the ice water through the electric valve 2 who is the ice water host 1 steam ^ 1 〇, in order to absorb the cold energy generated by the ice water host i operation The cold ice water can be circulated through the balancing valve 4 a, and then in the second cycle of the Lipu Bu, ie, the proportional control skirt 5, the equipment load 6, and the balancing valve 43 Pu 3 formation - equipment load cycle 丄 3; this one cycle is not, the excess high pressure low temperature ice water on the secondary side of the equipment load cycle 13 via the balancing valve 4a, the bypass pipe 8, the constant pressure difference control device opened at a plurality of ratios After flowing back to the primary circulation pump 3, after the electric valve 2, which into the ice water host 1 evaporation 1 § 1 0 formation - the secondary cycle 1 1. When the pressure of the secondary cycle 12 is greater than the pressure of the primary cycle 11, the secondary circulation pump 7 can pump most of the ice water into the equipment load 6 and the balance valve 4b via the proportional control device 5, and then flow back to the primary circulation pump 3, and then The ice water is transferred to the evaporator 10 of the ice water main unit 1 via the electric valve 211 in one cycle, so as to absorb the cold energy generated by the operation of the ice water host 1 = the cold ice water can be further passed The balancing valve 4 a flows back to the secondary circulation pump 7 to form an equipment load cycle 13; the secondary circulation does not flow into the equipment load cycle 丄 3 - the secondary side of the excess high-pressure high-temperature ice water to the secondary circulation pump 7 through the ratio The control split 5π is input into a load controller 6, the balance valve 4b, the bypass pipe 8, and the constant pressure difference control device 9 opened at a ratio of 200912224, and then flows back to the secondary circulation pump 7 to form a secondary cycle 12. It can be seen from the above that the bypass pressure difference control energy-saving ice water system of the present invention has the compatibility of the primary and secondary side pressures of the ice water system, the ice water temperature does not interfere with each other, and the energy use efficiency can be improved and reduced.
