Description
Technical field
The present invention relates to the attemperater that a kind of storage type water heater (water heater) uses, especially a kind of Multicarity is the heat preservation storage water tank of mixed water not.Main range of application is: various storage type water heaters, water heater, particularly various heat pump water-heating machines (water heater) comprise air-source, water source, ground source heat pump hot water equipment.
Background technology
The hot water of hot water machine, water heater use generally have peak, low-valley interval minute, for power configuration and the cost that reduces main process equipment, scarcely adopt Instant heating typely, and adopt the storage-type working method, therefore all to use heat preservation storage water tank.
Heat pump water-heating machine is the most energy-conservation in present all kinds of hot water machine, compares electric heater, and average energy is saved 75% electric weight, is also therefore at present with the fastest developing speed, the most promising product.
All kinds of storage-type electric water heaters, hot water storage tank that hot water machine is used, the structure of its water tank, function and application mode directly have influence on performance and the energy consumption of whole equipment, especially the operation principle between existing cisten mechanism, water tank and the hot main frame of pump is not enough to some extent, has affected its performance, power consumption and cost.
The working method that present storage-type heat pump water-heating machine coordinates with water tank roughly is divided into two kinds:
The first water-mixing type list water tank mode: heat pump water-heating machine is joined single water tank: water tank is inner is single cavity, the in-built full water of cavity, water body is the little integral body of free-pouring, variant position temperature difference, water tank has a cold water water supplement port and a hot water feed water inlet, how much hot water the feed water inlet emits, and how much cold water water supplement port enters.A: if circulating heat pump, water tank also has the circulation that is connected with the heat pump main frame through water pipe to heat a circulation water inlet and a circulating outlet of use; There is a water circulating pump that water body continuous circulation between the heat exchanger of heat pump main frame and water tank is flowed, the heat that the heat pump main frame is produced passes to the water body in water tank and water body is progressively heated up, when in water tank, water temperature reached design temperature (being generally 50～60 ℃), main frame quit work; Water temperature in water tank is reduced to design temperature-return difference value (being generally 5 ℃, adjustable), and main frame restarts and heats; Be 55 ℃ as design temperature, 5 ℃ of return difference values, in water tank, water temperature reaches 55 ℃, main shut-down system, during lower than 50 ℃, main frame is again started shooting and is heated.B: if the non-circulating type heat pump water-heating machine of water tank built-in heat exchanger, water tank has a cold water water supplement port and a hot water feed water inlet, in water tank, built-in heat exchanger (condenser) is arranged simultaneously, general heat exchanger is arranged on the bottom of water tank, and it heats temperature control mode and is analogous to circulating heat pump: during the main frame operation, the high-temperature gas refrigerant of compressor enters heat exchanger (condenser), during the refrigerant condensation, heat is passed to water in water tank, and water temperature is raise, and when reaching design temperature, main shut-down system; When water temperature drops to design temperature-return difference value, the main frame operation of again starting shooting heats.
The two water tank modes of the second: heat pump water-heating machine is joined a partial circulating water tank and a large storage tank (must be the non-bearing type water tank): little water tank is generally 1:5～10 with the ratio of large water tank volume, little water tank is furnished with the moisturizing magnetic valve, the magnetic valve that draws water, water pump draws water, level sensor, large water tank are furnished with level sensor and booster water pump; During little water tank moisturizing, the water compensating valve on little water tank is opened, and water pumping valve is closed, the water pump that draws water is stopped transport, and moisturizing has been expired, and water compensating valve is closed, main frame carries out circulating-heating to the water of little water tank, and water temperature has reached temperature, and the heat pump main frame is out of service, water pumping valve is opened, and the suction pump operation is delivered to large water tank to the hot water of little water tank, hot water in little water tank exhausts, and suction pump is stopped transport, and water pumping valve is closed, water compensating valve is opened moisturizing again, enters next work period; So circulation continuous operation, until large storage tank water is when full, the heat pump main frame is out of service; Large water storage tank water level drops to certain position, and system roll-back heats.
The first water-mixing type list water tank fairly simple also is widely used the most, but hot water can little for amount (when especially moisturizing temperature be low), water temperature stability and Energy Efficiency Ratio very poor.Its major defect 1: use at short notice the hot water of the water tank capacity more than 1/3, water temperature can descend rapidly.Because the water in water tank is full all the time, so release how much hot water, namely replenish how much cold water, hot and cold water can mix, and releases more hot water in the short time, and the water temperature in water tank namely is significantly less than design temperature, can not satisfy the water temperature requirement of use.As to set the hot water temperature be 55 ℃, and the water inlet cold water temperature is 10 ℃, releases half hot water in the short time, and in water tank, water temperature below 40 ℃, can't continue normal use; Namely one case full hot water that reaches temperature, only used part amount, and water temperature just can not have been used well below design temperature; When inflow temperature is low, guarantee the hot water supply of a certain quantity in the short time, water tank capacity must be more than 3 times of this quantity.Major defect 2: Energy Efficiency Ratio is low, and heating capacity is little, and the equipment allocating power is large, and equipment is under the defective mode of high condensation temperature, high condensing pressure, large running current for a long time works.Because its working method is that water temperature is reduced to design temperature-return difference value (being generally 5 ℃), main frame restarts and heats; Be 55 ℃ as design temperature, 5 ℃ of return difference values, in water tank, water temperature reaches 55 ℃, main shut-down system, during lower than 50 ℃, main frame is again started shooting and is heated; Therefore, very the most of the time is that the water of water temperature higher than 50 ℃ is heated to equipment; And a topmost characteristic of heat pump water-heating machine is: water temperature is lower, and the refrigerant condensing pressure of heat pump, evaporating pressure also lower, refrigerant height pressure reduction are less, and Energy Efficiency Ratio is higher, and heating capacity is larger simultaneously; Otherwise water temperature is higher, and the condensing pressure of heat pump, evaporating pressure are also higher, and refrigerant height pressure reduction is larger, and Energy Efficiency Ratio is lower, and heating capacity is less simultaneously; Therefore the working method of the first water-mixing type list water tank, have a greatly reduced quality the due energy-saving effect of Teat pump boiler, works under high condensing pressure and large running current situation for a long time because of the main frame compressor simultaneously, can shorten equipment life.Under winter maximum conditions, be the moisturizing temperature that the cool water heating of 100 liters of 5 ℃ is to 55 ℃ of design temperatures equally, the effect that compares two kinds of water tank modes: two water tank modes: little water tank volume is 100 liters, equipment is warmed to 55 ℃ to 100 premium on currency gradually from 5 ℃, and the water temperature mean value that heats in process is 30 ℃; Water-mixing type list water tank mode: be 1000 liters as the water tank volume, release 100 liters of 55 ℃ of hot water, fill into 100 liters of 5 ℃ of cold water, after mixed water, water temperature is about 50 ℃, the heat pump main frame is warmed to 55 ℃ to 1000 premium on currency gradually from 50 ℃, heats that in process, water temperature mean value is 52.5 ℃.Two kinds of different modes, water temperature mean value differs 22.5 ℃, two water tank modes should be more than 2:1 with the ratio of the final Energy Efficiency Ratio of water-mixing type list water tank mode, namely equally 100 premium on currency are warmed to 55 ℃ gradually from 5 ℃, the energy consumption of two water tank modes is less than half of the energy consumption of water-mixing type list water tank mode.Inflow temperature be the situation of 5～10 ℃ in the winter time the time right and wrong usually see, and be equipment running load maximum winter, when operating mode is worst, the result of use that the main frame of the first water-mixing type list water tank and the collocation mode of water tank and operation principle can have a strong impact on heat-pump apparatus: increase power consumption, reduce heating capacity, reduce the hot water supply, water temperature fast-descending in use procedure, this phenomenon are particularly serious with air source heat pump again.The heat-pump apparatus of water-mixing type list water tank mode is as providing enough heating capacities in the winter time, only have by following means: the one, add and join the large power, electrically heater, so just further reduced Energy Efficiency Ratio, the 2nd, allocating power or the number of units of increase heat pump main frame have so just increased equipment investment cost.Heat pump main frame running time in winter and energy consumption account for the whole year more than 50% simultaneously, and its low-energy-efficiency is than annual general effect and the operating cost that will greatly have influence on equipment.Major defect 3: no matter how much hot water actual the use needs, all must all heat the water of FCL and reach Wen Caike and use, cause heating the stand-by period long, and exhaustless hot water be wasted energy by cooling gradually.
Though the two cisten mechanisms of the second can be avoided 3 major defects of the mixed water list water tank mode of the first, have Energy Efficiency Ratio and heating capacity is high, heat fireballing advantage, its weak point is also arranged.Its major defect comprises: 1, increased water tank number, suction pump, a plurality of magnetic valve, level sensor, connecting line have also increased the complexity of system, the probability of fault and cost and the construction volume of system.2, the water tank of this structure can not adopt bearing type water tank, therefore for assure feed water hydraulic pressure must add booster pump, and to low power household heat pump water heater, configures two water tanks, and it is improper and uneconomic adding booster water pump.

Beneficial effect of the present invention:
Water tank of the present invention is applied to circulating heat pump, and its major advantage is:
1, compare water-mixing type list water tank, greatly the degree of the mixed water of the minimizing hot and cold water of degree is (depending on what of dividing plate number, can reduce the mixed water degree of 70%-95%): A: when water body is static, dividing plate is isolated in water body in each cavity, makes it to flow freely mixing, and the thermal conductivity factor of water is less, it is the non-conductor of heat, add the isolation of upper spacer, the conduction heat of the water body between different cavitys is seldom compared the heat exchange of convection current mixing generation and can be ignored.B: when reaching temperature except the water circulating pump leaving water temperature, the first return pipe can be switched on, the 1st cavity is transported to the N cavity to the water body between the M cavity by water pump, has simultaneously water body to flow into according to this outside M cavity to the 1 cavity from the M+1 cavity, and other times the first return pipe all is turned off; When the first return pipe is turned off, the 1st cavity forms a semi-enclosed space to M cavity and outer water pump and circulating water pipe, and unique passage of outside is the water hole between M cavity and M+1 cavity, when this semi-enclosed space was full of water body, water body can not be by the turnover of the water hole between M cavity and M+1 cavity; Therefore the hot water in water tank is from feed water inlet outward supplying heat water, and when cold water flowed into from the water supplement port of M+1 cavity, cold water can enter M+1 cavity and follow-up cavity flow according to this to the feed water inlet direction of N cavity, and can not enter M cavity to the 1 cavity; Equally when the 1st cavity is recycled heating to the water body of M cavity, also can be by the outflow of the water hole between M cavity and M+1 cavity.C: from the M+1 cavity to the N cavity except the hot and cold water transition region have 1-2 cavity hot and cold water mixability large, the hot and cold water of the cavity before and after transition region is isolated, keeps respectively the moisturizing cold water temperature and reaches the state of warm water's temperature.Guaranteed like this that under all operating modes, hot and cold water does not all mix, hot water effluent's temperature does not descend and water heating be fully utilized; Therefore compare water-mixing type list water tank, increase considerably the supply of hot water or dwindle the volume of water tank.
2, compare water-mixing type list water tank, the Energy Efficiency Ratio of raising system and heating capacity, save operating cost and equipment investment volume: the present invention only has the 1st cavity to heat to the participation of the water body between M cavity circulation when heating, and progressively heat up from the low temperature near moisturizing and arrive temperature, the cold water that fills into from the M+1 cavity can not mix with the hot water and the water that heats that circulating that reach temperature, avoided the low-temperature cold water of water-mixing type water tank to sneak into reaching the warm water heating again the high situation of average water temperature that is heated; In process, on average water temperature is low because circulation heats, and makes the poor mean value decrease of condensing pressure, evaporating pressure, high-low pressure of refrigerant in heating process; The reduction that high-low pressure is poor brings the raising of Energy Efficiency Ratio and the increase of system's refrigerant circulation, the increase of refrigerant circulation and the reduction of evaporating pressure, the increase that brings heating capacity; Thereby significantly improve equipment Energy Efficiency Ratio and heating capacity, reduced allocating power or the number of units of heat pump main frame.Especially in the winter time the hot and cold water temperature difference is maximum, and load is maximum, and the adverse effect of water-mixing type water tank is maximum, and advantage of the present invention is also brought into play the most fully, can significantly improve the undesirable present situation of air source heat pump heating effect in winter.The configuration of heat pump main engine power is by maximum load configuration in winter, and by above analysis and experiment test, the present invention can reduce approximately main engine power configuration or the corresponding number of units of 30% left and right than water-mixing type list water tank mode.
3, compare water-mixing type list water tank and two water tank application mode: the present invention has following function: reach same hot water design temperature, only need the highest relatively low refrigerant condensation temperature; The highest identical refrigerant condensation temperature can reach higher hot water design temperature.Heat in process in circulation, the leaving water temperature of heat pump main frame and backwater (water inlet) temperature has a difference, according to pump capacity, environment temperature and water temperature and different, scope between 3-12 ℃, 6 ℃ of average out to; Water temperature in conventional water box of heat pump water heater is the return water temperature (inflow temperature) of heat pump main frame, so the water temperature in water tank is when reaching design temperature, and the leaving water temperature of heat pump main frame will be higher than 6 ℃ of design temperatures; And use the heat pump main frame maximum water temperature of water tank of the present invention to be design temperature.Therefore can improve Energy Efficiency Ratio, reduce the highest condensing pressure or improve the design temperature upper limit, and under the highest identical condensing pressure condition, can make the design temperature upper limit of hot water improve 6 ℃, be a great improvement to the performance of heat pump main frame.
4: can only produce part but not FCL hot water according to the water consumption needs, reach Quick for reaching the warm water, shortening stand-by period and energy-conservation purpose: if only need to a small amount of hot water and do not need whole water tank hot water, only need to produce a small amount of hot water of part, making has the hot water of the enough uses that reach temperature to get final product in several cavitys of feed water inlet side, shortened heating and the stand-by period, saved the energy.
5: avoided two water tank modes phenomenon of main frame frequent start-stop machine in the course of the work.
6: reduce by 1 water tank than two water tank modes.
7: can be used for bearing type water tank, save booster water pump.
Water tank of the present invention is applied to the heat pump water-heating machine of water tank built-in heat exchanger, its advantage basic with above-mentioned circulating heat pump roughly the same; Avoided simultaneously the water body phase heat exchanger of heat pump water-heating machine of existing water tank built-in heat exchanger without flowing, the phenomenon that heat transfer effect is poor, Energy Efficiency Ratio is low.
Water tank of the present invention is applied on electric heater, and major advantage is to guarantee not mix water, guaranteed the stable of leaving water temperature, can part but not whole box water heat, reach the fast energy-saving effect.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, further set forth technical scheme of the present invention.
Embodiment 1: concrete structure and the course of work of the present invention on the circulation hot pump hot water machine:
The not mixed water attemperater of Multicarity as shown in Figure 1, comprise thermal-insulating body 1, cold water water supplement port 4, hot water feed water inlet 10 and be arranged on temp probe in thermal-insulating body 1, the inside of thermal-insulating body 1 is isolated into N cavity from the 1st to N by a plurality of dividing plates 2, and N is that natural number is not less than 8; The water hole 3 of the 1st cavity only is connected with the 2nd cavity, and the 1st cavity is equipped with a delivery port 5, and delivery port 5 picks out water pipe 8, and outlet pipe 8 is connected with outer water pump 12 water inlets; The water hole 3 of N cavity only is connected with the N-1 cavity, and the N cavity is equipped with hot water feed water inlet 10 and the first water return outlet 6; Be provided with the second water return outlet 7 at the M cavity, M＜N, and the M span is N/5～N/3; The first water return outlet 6 is connected with the outlet pipe of heat pump main frame through a three-way magnetic valve 11 by each self-corresponding return pipe 9 with the second water return outlet 7 again; Cold water water supplement port 4 is located at the M+1 cavity; Except the 1st and two cavitys of N respectively only with an adjacent cavities is connected, other each cavity is by water hole, is connected with adjacent last cavity and a rear cavity respectively; Water tank inside consists of from the 1st cavity to the N cavity,, water-flowing path that be communicated with each cavity that connect successively each cavity.
As preferably, a plurality of dividing plates in water tank or barrier film are not less than 6 for be arrangeding in parallel; One side of each dividing plate is having aquaporin near inner water tank wall place, from the vertical direction of dividing plate, crosses two sides that aquaporin lays respectively at the right opposite of cavity on two adjacent dividing plates.Delivery port was gone up opposite one side of aquaporin at the dividing plate (the 1st dividing plate) of this cavity; Water return outlet was gone up right opposite one side of aquaporin at the dividing plate (N dividing plate) of this cavity.
As shown in Fig. 2 and 3, preferred as another kind of cisten mechanism, the dividing plate in water tank wherein has at least two to be cross one another.Perhaps all dividing plates are arranged in a crossed manner, can farthest optimize the space in water tank, go out as much as possible independent cavity with minimum baffle for separating.
water tank of the present invention is as follows in the course of work on the circulation hot pump hot water machine: A: be all under the state of cold water when whole water tank, three-way magnetic valve is closed the first return pipe, conducting the second return pipe, the water circulating pump operation, the heat pump main frame is opened and is heated, the 1st water in the M cavity progressively heats up, and the water body in other cavitys does not participate in heating, water temperature can not raise, when main frame water outlet (water container backwater) when reaching design temperature, three-way magnetic valve switches, conducting the first return pipe, close the second return pipe, the 1st hot water in the M cavity is pumped to the N cavity, and flow into step by step N-1, the N-2 cavity N, N-1, cold water in the N-2 cavity is extruded, the cold water of M+1 cavity and follow-up cavity flows into M to the 1 cavity successively, after a period of time, descending appears in the main frame leaving water temperature, when dropping to design temperature-(10 ℃ of return difference values, adjustable) time, three-way magnetic valve switches again, close the first return pipe, conducting the second return pipe, begin the process that heats of next circulation.Go round and begin again, when main frame water outlet (water container backwater) when reaching design temperature, and the water temperature of M+1 cavity and follow-up cavity reaches certain and imposes a condition (as M+4 cavity water temperature＞moisturizing temperature+10 ℃, adjustable) time, main frame is out of service, water major part in state table open fire case is all to reach the warm water at this moment, and the cold water deficiency of M+1 cavity and follow-up cavity is full of the 1st to the M cavity; The continuous export-oriented supplying hot water in feed water inlet on the N cavity, cold water constantly fills into and flows to follow-up cavity from the M+1 cavity, and during M+4 cavity water temperature≤moisturizing temperature+10 ℃, host-initiated heats.
B: whole water tank is all under the state of hot water, when water tank outward supplying heat water, cold water fills into from the M+1 cavity, and progressively flow into the follow-up cavitys such as M+2, when reaching certain, the water temperature of M+1 and follow-up cavity imposes a condition (as M+4 cavity water temperature≤moisturizing temperature+10 ℃, adjustable) time, three-way magnetic valve is closed the second return pipe, conducting the first return pipe, host-initiated heats, water pump operation, the hot water the 1st in the M cavity pumps into the N cavity, and the cold water in this moment M+1 and follow-up cavity flows into 1 cavity M to the according to this; When the main frame leaving water temperature dropped to design temperature-return difference value (10 ℃, adjustable), three-way magnetic valve switched, and conducting the second return pipe is closed the first return pipe, and the water to the 1st in the M cavity circulates and heats; When main frame water outlet (water container backwater) reaches design temperature, and M+4 cavity water temperature＞moisturizing temperature+10 ℃, main frame is out of service; When main frame water outlet (water container backwater) reaches design temperature, and M+4 cavity water temperature≤moisturizing temperature+10 ℃, three-way magnetic valve switches, and conducting the first return pipe is closed the second return pipe, and the hot water the 1st in the M cavity pumps into the N cavity, and main frame continues to move.
C: other state can be by above 2 kinds of State reasonings.
When be full of water in water tank, when the first return pipe is closed, no matter whether main frame moves, the 1st water body in the M cavity all can not exchange with the water body of other cavity; Because water tank is the Multicarity structure, simultaneously the turnover water hole on cavity is installed in the diagonally opposing corner of relative two walls of cavity, the cold water that therefore fills into promote hot water to the feed water inlet one side Cavity Flow; The hot water that pumps into equally the N cavity promotes cold water to the 1st cavity one side flow, all the time be to reach the warm water in several cavitys of feed water inlet one end in the assurance water tank, cold water is at opposite end, only have a few cavity of hot and cold water transition region to have hot and cold water to mix the water phenomenon, the hot and cold water of other cavity can not mix; The heat temperature raising of water body is realized between the 1st to the 4th cavity all the time simultaneously, and rises to gradually design temperature from low water temperature, and in heating process, average water temperature is lower, and heating capacity is large, and Energy Efficiency Ratio is high.
Embodiment 2: the present invention is in the concrete structure on the heat pump water-heating machine of water tank built-in heat exchanger and the course of work: cisten mechanism and the course of work are substantially substantially the same manner as Example 1: heat exchanger (condenser) is arranged on the 1st between the M cavity, water supplement port is at the M+1 cavity, the 1st cavity upper water-out mouth is connected with a small-power pump intake, N and M cavity arrange respectively two water return outlets and corresponding return pipe, and 2 return pipes are connected with pump outlet through a three-way magnetic valve.When heating, three-way magnetic valve makes the second return pipe conducting, and the first return pipe is closed, water pump operation, water body circulates intensification the 1st between the M cavity, when the main frame leaving water temperature reaches design temperature, and M+4 cavity water temperature＞moisturizing temperature+10 ℃ (adjustable), main frame is out of service; When the main frame water outlet reaches design temperature, and M+4 cavity water temperature≤moisturizing temperature+10 ℃, main frame continues operation, and three-way magnetic valve switches, conducting the first return pipe, close the second return pipe, the hot water the 1st in the M cavity pumps into the N cavity, and the low temperature water body of M+1 and follow-up cavity flow into 1 cavity of M to the, when the water pump water outlet temperature drops to design temperature-(10 ℃ of return difference values, adjustable), three-way magnetic valve switches, and enters next and heats circulation.
