Said valve 1 is commercial universal valve, selects brass ball valve.
Wherein, valve 1 (containing threeway), main water box 11, secondary water tank 3, mixed water controller 5 and spray equipment 6 constitute a water route, are called main water route; Valve 1 (containing threeway), regenerator 7, mixed water controller 5 constitute a water route parallelly connected with main water route, are called Zhi Shuilu; Spray equipment 6, regenerator 7 (outer surface) and evaporimeter 8 (outer surface) constitute an open water route, are called outer water channel; Condenser 2, throttling arrangement 10, evaporimeter 8 constitutes a cold-producing medium closed-loop path with compressor 9, is called heat pump circuit; Outer water channel passes to Zhi Shuilu through regenerator 7 with the part of shower waste heat; Outer water channel passes to heat pump circuit, the direct discharging of waste water after the heat exchange through evaporimeter 8 with the part of shower waste heat; Heat pump circuit heats compressor 9 through condenser 2 and passes to main water route.
Wherein, Zhi Shuilu is parallelly connected with main water route, and the more main water route of Zhi Shuilu water temperature water temperature is low, and the two mixes through mixing water controller 5, mixes water controller 5 and regulates mixed water temperature, i.e. water outlet water temperature through main water route and Zhi Shuilu flow proportional.
Wherein, Preheater 4 in the secondary water tank 3 is equipped with built-in temperature control equipment; Preheater 4 power are suitable with compressor 9 power; The two is not worked simultaneously, can realize the switching of the two duty through manually operated switch and automaton, and the mean temperature of secondary water tank 3 spray equipment more than 45.0 ℃ the time could be opened; Compressor 9 only starts preheater 4 work under other situation of normal operating conditions under spray equipment 6 water outlets and secondary water tank 3 water temperatures are lower than the situation of the leaving water temperature that the user sets.
Mix water controller 5 and can regulate the spray shower temperature of mixing behind the water through the flow of regulating running water in the regenerator 8.
The circulation route of cold-producing medium is: evaporimeter 8 → compressor 9 → condenser 2 → throttling arrangement 10 → evaporimeter 8.The pipeline of running water has two; Article one, be: condenser 2 → water tank 3 → mixed water controller 5 → spray equipment 6; Another is: regenerator 7 → mixed water controller 5 → spray equipment 6; Article two, the running water of pipeline mixes in mixed water controller 5 at last, is used for the shower spray, and shower waste passes through regenerator 7 and evaporimeter 8 again with heat recovery then.Article two, the water route connects in parallel; Compare with the connected mode of series connection; Improved the inflow temperature of condenser 2, reduced heat transfer temperature difference, the heat exchange efficiency of condenser 2 has been had certain favourable influence; Can reduce simultaneously the size of condenser 2 to a certain extent, help the miniaturization of heat pump water heater system.
When using this water heater, at first want preheating, when the fully preheating of water heater during greatly about 60 ℃ of left and right sides of the temperature of whole secondary water tank 3, can begin shower, the process of preheating is greater than needs about 15 minutes; Temperature controller built-in in the preheater 4 can stop preheater 4 preheatings when secondary water tank temperature is higher than 75 ℃, wait for user's shower.With the preheating power of 3500W, the 2.5L water tank, 15 ℃ of water temperatures are example, be about 2.25 minutes preheating time.
Preceding 10 seconds after shower begins; Heat pump is not worked, and the hot water of shower supposes that from secondary water tank the temperature of water in the secondary water tank of shower room is 60 ℃; When shower begins back 10 seconds; During the instant heating pump startup, the mean temperature of secondary water tank 3 is 50.5 ℃, and the hot water during this section in the secondary water tank 3 can satisfy the requirement of shower fully.After heat pump was opened, the mean temperature of secondary water tank 3 can present downward trend gradually, to the last reaches a poised state.The power of heat pump compressor 9 is 3500W, and efficient is 0.8, and when condensed water discharge was 4.8L/min, the leaving water temperature of secondary water tank 3 was 48.3 ℃ after the balance.The variation tendency of flow of spray also descends gradually, and also can arrive a poised state at last, if set 40 ℃ shower temperature, the shower water flow that reaches after the poised state is 9.1L/min.This state continues always then, in the shower process, cuts off the water.
After cutting off the water, heat pump stops immediately, and preheater 4 is opened simultaneously, and the water in the secondary water tank 3 is heated, and the initial heat source when starting once more as heat pump still has the delay in 10 seconds when heat pump starts once more.When water stopping time more in short-term, the heats of preheater 4 will be not remarkable, may occur starting the situation that enough initial heat source are provided to heat pump.Situation with worst is an example; Start spray equipment 6 after promptly cutting off the water immediately, preheater 4 was only worked 10 seconds at every turn, when heat pump starts once more; Leaving water temperature in the secondary water tank 3 is 42.0 ℃, still can well-off shower hot water and the requirement of satisfying heat pump startup initial heat source.If but spray equipment 6 is at once opened again in the back that cuts off the water once more immediately, the leaving water temperature of secondary water tank 3 was 37.5 ℃ when heat pump started once more, can not satisfy bathing and the requirement of initial heat source is provided for the heat pump startup.That is to say and restart spray equipment 6 immediately after doublely cutting off the water.
This situation also is few the appearance, but should consider, best solution is exactly the mean temperature in the secondary water tank 3 of monitoring.If the leaving water temperature that guarantees secondary water tank 3 after the spray in 10s is more than 40 ℃, the mean temperature of secondary water tank 3 will remain on more than 45.0 ℃ at least when then starting spray.Therefore also to monitor the mean temperature of secondary water tank 3,, only make and to open at the mean temperature of secondary water tank 3 spray equipment 6 more than 45.0 ℃ the time through the control action of control system.When this situation of seldom seeing occurs, open spray equipment 6 back spray equipments 6 will be certain hour after could water outlet, but owing to preheater power is bigger, this time is very of short duration, no longer than 15s, can not influence user's normal use.Fig. 2 is the control system schematic of Teat pump boiler.
