Teat pump boiler should not be in holding state for a long time, is the longlyest limited with 3 ~ 5 minutes.When secondary water tank 3 water temperature reaches user's capping value such as, time (65 DEG C), Teat pump boiler is by starting protection program automatic cut-off power.Occur that this situation can only illustrate that the use habit of user is bad, over time limit standby not only not energy-conservation, also enforce compression machine start and stop.
System is normally run:
Reach user in water tank water temperature and set output water temperature such as, under the condition of (45 DEG C), open mixed water valve O and hold, current inductive switch 14 sends the signal that Teat pump boiler enters duty, and control circuit board sends control signal and causes change as follows:

3break-make now also by the control of temperature sensor 13, if water temperature continues to set output water temperature higher than user, relay T
3just automatically disconnect, make electric heater R

2quit work, on the contrary T
3automatic make contact p
3.The result that circuit switches is that compressor 1 enters rated voltage duty, plays main heat effect, electric heater R
1, R
2power is minimum, plays auxiliary heating effect.
The a of triple valve 11
2and b
2two ends are connected; Now, water route is open, by feed water valve 12, through water tank and gondola water faucet 4, for user's shower, carries out heat exchange, finally enter Xia Shui and drain after using by waste-heat recoverer 5.
Wherein, waste-heat recoverer 5 is equivalent to evaporimeter, and now, compressor is close to rated power operation, so refrigerant flow is comparatively large, absorb amount of heat from waste-heat recoverer 5, these heats come from shower waste, finally, this part heat is released at main water box heat exchange pipeline 21, and water supply heats.
System halt:
If user mixed water valve O of Temporarily Closed in bathing process holds, water heater will enter into holding state, with system standby state consistency noted earlier, that is: relay T
1make contact p
1, relay T
2make contact p
2, relay T
3make contact p
3, relay T
4disconnect; The b of triple valve 11
2and c
2two ends are connected.Suspend and usually do not last for a long time; user can recover to use usually before exceeding the standby time limit; so the probability entering automatic guard mode is under normal usage very low very low; namely under normal circumstances; compressor is in running order all the time; can not cause damage because of frequent start-stop, the probability broken down also reduces greatly.
Under gravity, under water sink larger compared with low-density of temperature in evaporating heat exchanger 6 shell side, enter main water box 2 shell side through secondary water tank 3, in main water box 2 shell side, less waterborne floating of the higher and density of temperature, is back to evaporating heat exchanger 6 shell side through secondary water tank 3 and completes free convection water circulation.
Electric heater R
1, R
2the selection of resistance value, should consider its power output under rated voltage during parallel operation and compressor rated power roughly the same so that general power is steady when keeping Teat pump boiler to run.Meanwhile, electric heater R
1, R
2resistance in parallel a little more than the resistance of inducting of compressor so that at least can dividing potential drop more than 1/2 when resistance connect with motor, effective reduction compressor power consumption.
Integrated water tank in Fig. 2 and Fig. 4 about can hold 8 liters, running water, does not start compressor, only with heater, can not form free convection, about 3 liters, the region that heater can affect, i.e. about 3 liters of secondary water tank volume.With two 40 ohm of electric heater parallel connections, heating power during voltage 220V is 2.4kW, tap water temperature 20 DEG C, and setting output water temperature 45 DEG C, be about 132 seconds preheating time, 2 minutes more youngsters, close to instant-heating.
The normal operate power 1.8kW of compressor, when proceeding to holding state, electric current 6.5A, the electric resistance partial pressure of 20 ohm is 130V, and compressor ME for maintenance is 90V, and power is 0.6kW, is about 1/3 of rated power, effectively heats about 0.4kW; Electric heater heating power 0.85kW; System input power 1.43kW, total thermal power 1.25kW; The water extraction of 8 liters 45 DEG C (first operation has 5 premium on currency temperature 20 DEG C) is risen to user's limiting temperature 65 DEG C by system, 9 minutes consuming time, mean that the standby time limit can reach 9 minutes, period approximately wastes electricity 0.03 degree, less than 5 points of because maintain compressor operation.In actual use, the holding state time can be compressed into 3 ~ 5 minutes even shorter, so can not how many energy consumptions be produced, even also energy-conservation than variable frequency adjustment.
When heat pump normally works, heating COP according to heat pump is 5.0 estimations, only need not heating power 9.0kW in electrically heated situation with compressor, inflow temperature 20 DEG C, under the condition that leaving water temperature is 45 DEG C, water flow can reach 5.2L/min, substantially the demand of most of user can be met, increased flow capacity, or electric heater auxiliary heating, otherwise leaving water temperature is established more lower slightly.Leaving water temperature 45 DEG C, under the condition of water yield 5.2L/min, as long as the water flow energy arriving waste-heat recoverer heat exchange surface reaches 85%, temperature is more than 40 DEG C, through heat exchange, temperature at discharging condensate can reach 15 DEG C, just can reclaim the heat of more than 7.5kW, match with the refrigerating capacity of heat pump, the demand of evaporimeter heat-obtaining can be met completely.
Compressor normally runs, and auxiliary heater is in parallel with it, and two resistant series are 80 ohm, and power is 0.6kW, and system running at full capacity power is about 2.4kW, the water yield that now can reach, and is equivalent to the instant-heating formula electric heater of 9.5kW.By comparison, power reduction 7.1kW, fractional energy savings is close to 75%.
Compared with overall energy-saving rate, the energy of standby period loss is very little.
