Embodiment
As shown in Figure 1, the utility model family expenses transfiguration step-less adjustment instant heating type heat pump water heater comprises refrigerant-cycle systems, water system, control system;
Described refrigerant-cycle systems comprises compressor 1, evaporimeter 2, condenser 10, expansion valve 6, blower fan 3, two-way electromagnetic valve 11; The outlet of described evaporimeter 2 is connected by the import of pipeline with compressor 1; The outlet of described compressor 1 is connected with the refrigerant inlet of condenser 10 and the entrance of two-way electromagnetic valve 11 respectively by pipeline, and the outlet of described two-way electromagnetic valve 11 is connected with the import of evaporimeter 2 by pipeline 5; The refrigerant outlet of described condenser 10 is connected with the entrance of evaporimeter 2 through expansion valve 6; Described compressor 1 adopts digital scroll compressor, and evaporimeter 2 is equipped with blower fan 3.
Described water system comprises cold water pipe 15, flow control valve 14, mixed water valve 8, described cold water pipe 15 is divided into two-way, the flow control valve 14 of wherein leading up to is connected with the entrance water pipe of condenser 10, and the outlet water pipe of condenser 10 connects mixed water valve 8, and another road directly is connected with mixed water valve 8;
Described control system comprises defrosting detecting sensor 12, current detecting sensor 13, cooling-water temperature sensor 9, the compressor transfiguration step-less adjustment controller 16 that is connected with fuzzy controller 17; Described defrosting detecting sensor 12 is arranged on the evaporimeter 2; Described current detecting sensor 13 is arranged on the outlet water pipe of flow control valve 14; Described cooling-water temperature sensor 9 has two, and one of them is arranged on the import water pipe of flow control valve 14; Another is arranged on the outlet water pipe of condenser 10; Described compressor transfiguration step-less adjustment controller 16 is connected with compressor 1; Described fuzzy controller 17 also is connected with two-way electromagnetic valve 11.
Shower 7(or tap are installed in the outlet of described mixed water valve 8).
Operation principle of the present utility model: when shower 7 is opened, current detecting sensor 13 is experienced signal, compressor 1 low carrying starts, refrigerant-cycle systems work, 10 pairs of cold water from cold water pipe 15 of condenser (being running water) heating, fuzzy controller 17 is regulated the output capacity of compressor 1 and the water flow of shower 7 by the signal of current detecting sensor 13, cooling-water temperature sensor 9, makes leaving water temperature and flow satisfy customer requirements.Yet; use in the hot water process the user; can often need of short duration situation (when being coated with shampoo such as wash my hair) of closing shower 7; generally reopen shower 7 after about 20～180 seconds; after these family expenses transfiguration step-less adjustment instant heating type heat pump water heater (hereinafter to be referred as water heater) was shut down, two-way electromagnetic valve 11 was opened immediately, and evaporimeter 2 directly communicates with condenser 10; pressure tends to balance very soon, guarantees the immediately startup after water heater is shut down.When environment temperature was lower than 10 ℃, frost can appear in evaporimeter 2, and during intermitten service, twice operation is lower than the defrost under stopped status of when setting value and once guarantees the efficient operation of refrigerant-cycle systems blanking time.
For further understanding this patent, the below illustrates.
Before using this water heater, set 40 ℃ of supply water temperatures at fuzzy controller 17 panels first, water-water jet 8 is arranged on whole hot water position, when shower 7 is opened, flow control valve 14 is under flow action, output signal, fuzzy controller 17 is successively to blower fan 3, compressor 1 sends startup command, this moment, water heater belonged to the low startup of carrying, the temperature value of the inflow temperature value that fuzzy controller 17 is sensed according to cooling-water temperature sensor 9 and evaporimeter 1 side defrosting detecting sensor 12 is made intellectual analysis and is judged, compressor 1 output capacity is adjusted under this operating mode sets value, water heater can obtain required supply water temperature when moving basically under this output capacity, deviation can finely tune to meet the demands by further output capacity a little.During stable operation, airborne heat energy is passed to the cold-producing medium in the evaporimeter 2, and under the supercharging transmitting effect of compressor 1, cold-producing medium enters into condenser 10, cold water (running water) in the heat transferred condenser 10 of cold-producing medium rises to the desired value of user with water temperature.
Why this water heater will hang down to carry starts (i.e. the low low pressure soft start that carries), when reason is that compressor 1 starts, starting current be running current 5～8 times, the rated power of 3HP compressor about 2.5KW, rated current 10～13A, starting current is more than the 50A, considerably beyond the predetermined value of general family electrical line setting, all the more so concerning the building construction that certain time limit is arranged, other household electrical appliance are caused use surge, therefore, startup in low year is very important.
In user's bathing process; when wash my hair is coated with shampoo; of short duration shower 7 phenomenons of closing often can appear; this moment, compressor 1 output capacity dropped to adjustable minimum; two-way electromagnetic valve 11 is opened simultaneously, directly enters into evaporimeter 2 from compressor 1 refrigerant vapour out, is unlikely because the water temperature over-high in the condenser 10 causes water heater to shut down; water heater is in the non-operating condition that heats all the time, as shown in Figure 2.When shower 7 was opened again, two-port valve electromagnetism 11 was closed, and water heater returns to rapidly normal operating condition.
Fig. 2 is the partial schematic diagram of Fig. 1, and purpose is for circulating path clearer, cold-producing medium when understanding the of short duration shutdown of water heater efficiently.
As seen from Figure 2; except above-described for the bathing process of short duration close shower 7 time running status; also be used for defrost process: in the winter time during outside air temperature lower (below 10 ℃); usually meeting frosting on the evaporimeter 2; if during continuous operating time very long (above 1 hour); frosting thickness heat exchanging causes adverse effect on the evaporimeter 2; need defrosting; for avoiding the defrost phenomenon in the shower process, occurring suddenly; move by force defrost in blanking time at compressor 1; two-way electromagnetic valve 11 is opened, and refrigerant vapour directly directly enters into evaporimeter 2 from compressor 1 outlet, and the frost on its surface is melted.Certainly, except adopt by on address the bypass defrost method that pipeline 5 consists of, can also adopt the method defrosting of laying heating wire at evaporimeter 1.
As mentioned above, just can realize preferably the utility model.
Above-described embodiment only is the better embodiment of the utility model; but embodiment of the present utility model is not restricted to the described embodiments; other are any not to deviate from change, the modification done under Spirit Essence of the present utility model and the principle, substitute, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
