A kind of operation method of the quick heating type heat pump water heater reclaiming shower used heat, details are as follows：

System warm-up：

User's control switch connection power supply, constant-temperature water mixing valve 8O end is closed, relay T₁Make contact p₁, continue Electrical equipment T₂Make contact p₂, relay T₃Make contact p₃, relay T₄Disconnect, electric heater R₁、R₂Parallel operation, secondary water tank 3 Interior water temperature begins to ramp up.Secondary water tank 3 built-in temperature sensor, sets output water temperature for example when water temperature reaches user, when (45 DEG C), Alarm user is entered holding state, compressor 1 starts simultaneously.

When completing start preheating, after the water temperature in secondary water tank 3 reaches user's setting output water temperature, compressor 1 will start to open Dynamic.During startup, relay T₁、T₂、T₃All disconnect, electric heater R1, R2 power-off, relay T₄Make contact p₄, compressor 1 is energized Start working.If after compressor 1 starts, constant-temperature water mixing valve 8O does not open at end, and Teat pump boiler will be automatically into holding state.

System standby：

Constant-temperature water mixing valve 8O end is closed, relay T₁Make contact p₁, relay T₂Make contact p₂, electricity plus Hot device R₁、R₂Parallel operation；Relay T₃Make contact p₄, relay T₄Disconnect, compressor 1 is connected with electric heater R1, R2 work Make, compressor 1 voltage reduces, electric current reduces, output reduces；The b of three-way valve 10₁And c₁Two ends are connected；The b of three-way valve 11₂ And c₂Two ends are connected；Pump 9 starts.

In the presence of pump 9, the water in secondary water tank 3 enters evaporating heat exchanger 6 shell side through pump 9, then passes through three-way valve 10 Enter main water box 2 shell side, eventually pass back to secondary water tank 3 and complete to close water circulation.In closure water cycle process, water is in evaporation and heat-exchange There is heat exchange with the cold-producing medium in tube side in the shell side of device 6, release heat, temperature reduces；With tube side in main water box 2 shell side There is heat exchange in interior refrigerant vapour, absorb heat, and temperature raises, and the heat absorbed in it is included in evaporating heat exchanger 6 The heat of middle release and the heat of 1 power consumption work(conversion of compressor；In secondary water tank 3, water absorbs electric heater R₁、R₂Release Heat, temperature raises further.Closure water cycle process is the process that the water to secondary water tank 3 is heated, and heating power is little In gross electric capacity, electric heater R₁、R₂Electrical power 100% be converted into thermal power, and the electrical power of motor M there are about 70% conversion For thermal power, so, on the premise of ensureing that compressor 1 remains standby, voltage is more distributed to electric heater R₁、R₂, with Reduce loss.

A kind of operation method of the quick heating type heat pump water heater reclaiming shower used heat, details are as follows：

System warm-up：

User's control switch connection power supply, constant-temperature water mixing valve 8O end is closed, relay T₁Make contact p₁, continue Electrical equipment T₂Make contact p₂, relay T₃Make contact p₃, relay T₄Disconnect, electric heater R₁、R₂Parallel operation, secondary water tank 3 Interior water temperature begins to ramp up.Secondary water tank 3 built-in temperature sensor, when water temperature reaches user and sets such as 45 DEG C of output water temperature, will Alarm user enters holding state, and compressor 1 starts simultaneously.Electric heater R₁、R₂Resistance be 40 ohm.

Compressor model 2V32S225A-2.5P selected by the present invention, but it is not limited to the compressor of this model, city On field, the compressor of other models is all usable in subject application.

When completing start preheating, after the water temperature in secondary water tank 3 reaches user's setting output water temperature, compressor 1 will start to open Dynamic.During startup, relay T₁、T₂、T₃All disconnect, electric heater R1, R2 power-off, relay T₄Make contact p₄, compressor 1 is energized Start working.If after compressor 1 starts, constant-temperature water mixing valve 8O does not open at end, and Teat pump boiler will be automatically into holding state.

System standby：

Constant-temperature water mixing valve 8O end is closed, relay T₁Make contact p₁, relay T₂Make contact p₂, electricity plus Hot device R₁、R₂Parallel operation；Relay T₃Make contact p₄, relay T₄Disconnect, compressor 1 is connected with electric heater R1, R2 work Make, compressor 1 voltage reduces, electric current reduces, output reduces；The b of three-way valve 10₁And c₁Two ends are connected；The b of three-way valve 11₂ And c₂Two ends are connected；Pump 9 starts.

In the presence of pump 9, the water in secondary water tank 3 enters evaporating heat exchanger 6 shell side through pump 9, then passes through three-way valve 10 Enter main water box 2 shell side, eventually pass back to secondary water tank 3 and complete to close water circulation.In closure water cycle process, water is in evaporation and heat-exchange There is heat exchange with the cold-producing medium in tube side in the shell side of device 6, release heat, temperature reduces；With tube side in main water box 2 shell side There is heat exchange in interior refrigerant vapour, absorb heat, and temperature raises, and the heat absorbed in it is included in evaporating heat exchanger 6 The heat of middle release and the heat of 1 power consumption work(conversion of compressor；In secondary water tank 3, water absorbs electric heater R₁、R₂Release Heat, temperature raises further.Closure water cycle process is the process that the water to secondary water tank 3 is heated, and heating power is little In gross electric capacity, electric heater R₁、R₂Electrical power 100% be converted into thermal power, and the electrical power of motor M there are about 70% conversion For thermal power, so, on the premise of ensureing that compressor 1 remains standby, voltage is more distributed to electric heater R₁、R₂, with Reduce loss.

Under gravity, due to refrigeration working medium evaporation endothermic in evaporating heat exchanger 6 tube side, lead in heat exchange pipeline 22 Hull-skin temperature reduces, under water sink larger compared with low-density of temperature in evaporating heat exchanger 6 shell side, enters main water box 2 through secondary water tank 3 Shell side, due to refrigeration working medium condensation heating in main water box 2 tube side, leads to heat exchange pipeline 21 surfaces externally and internally temperature to raise, main water box 2 Shell side is heated and density is less waterborne floating, is back to evaporating heat exchanger 6 shell side through secondary water tank 3 and completes free convection water and follows Ring.In free convection water cycle process, there is heat exchange with the cold-producing medium in tube side in water in the shell side of evaporating heat exchanger 6, Release heat, temperature reduces；There is heat exchange with the refrigerant vapour in tube side in main water box 2 shell side, absorb heat, temperature Raise, the heat absorbed in it includes the heat of the heat of release and 1 power consumption work(conversion of compressor in evaporating heat exchanger 6 Amount；When flowing through secondary water tank 3, water absorbs electric heater R₁、R₂The heat of release, a part of heated, float, a part is not Heated, sink.Closure water cycle process is the process that the water in integrated water tank is heated, and heating power is less than Gross electric capacity, electric heater R₁、R₂Electrical power 100% be converted into thermal power, and the electrical power of motor M there are about 70% and is converted into Thermal power, so, on the premise of ensureing that compressor 1 remains standby, voltage is more distributed to electric heater R₁、R₂, to subtract Few loss.

Described compressor (1), main water box (2), choke valve (7) and evaporating heat exchanger (6) and three-way valve (11) composition are treated Machine heat pump circulating system.Wherein, evaporating heat exchanger (6) is equivalent to vaporizer, and main water box 2 is equivalent to condenser, evaporating heat exchanger (6) for maintaining standby operation of heat pump to provide thermal source；Main water box 2 provides low-temperature receiver for maintaining standby operation of heat pump.Because Compressor 1 is in low pressure low-speed run state, then refrigerant flow is more much lower than running well, and now, compressor 1 adopts resistance 1/3～1/2 state of its voltage-regulation to rated voltage is kept on the go by the mode of partial pressure, brownout then easily stall.

Teat pump boiler should not be in holding state for a long time, the longest was limited with 3～5 minutes.When secondary water tank 3 water temperature reaches User sets higher limit for example, and when (65 DEG C), starting protection Automatic Program is cut off the electricity supply by Teat pump boiler.This situation occurs Can only illustrate that the use habit of user is bad, standby not only not energy-conservation over time limit, also force start/stop of compressor.

System is normally run：

Reach user in water tank water temperature and set output water temperature for example, under conditions of (45 DEG C), open water mixing valve O end, current Inductive switch 14 sends the signal that Teat pump boiler enters working condition, and control board sends control signal and leads to change such as Under：

Relay T₁Disconnect, relay T₂Make contact p₁, electric heater R₁、R₂Tandem working；Relay T₃Make contact p₃, relay T₄Make contact p₄, compressor 1 and electric heater R₁、R₂Parallel operation；Relay T₃Break-make now also be subject to temperature The control of sensor 13, if water temperature is higher than persistently user sets output water temperature, relay T₃Just automatic disconnection, makes electric heater R₁、 R₂Quit work, on the contrary T₃Turn on automatically contact p₃.The result of circuit switching is that compressor 1 enters rated voltage working condition, rises Main heat effect, electric heater R₁、R₂Power is minimum, plays auxiliary heat effect.

The a of three-way valve 11₂And b₂Two ends are connected；Now, water route is open, by feed water valve 12, through water tank and flower Spill 4, for user's shower, using rear, heat exchange is carried out by waste-heat recoverer 5, eventually enter into lower water and drain.

Wherein, waste-heat recoverer 5 is equivalent to vaporizer, and now, compressor is close to rated power operation, so cold-producing medium stream Amount is larger, absorbs amount of heat from waste-heat recoverer 5, and these heats come from shower waste, and finally, this partial heat is in main water Case heat exchange pipeline 21 is released, and water supply heats.

System halt：

If the user while Temporarily Closed water mixing valve O end during bathing, water heater will go into holding state, and above Described system standby state consistency, that is,：Relay T₁Make contact p₁, relay T₂Make contact p₂, relay T₃Make contact p₃, relay T₄Disconnect；The b of three-way valve 11₂And c₂Two ends are connected.Suspend and generally do not last for a long time, user would generally exceed Recovered before the standby time limit to use, so it is very low very low, that is, just to enter automatic protection shape probability of state under normal usage In the case of often, compressor is in running order all the time, will not cause damage because of frequent start-stop, and the probability breaking down is also big Big reduction.

Under gravity, under water sink larger compared with low-density of temperature in evaporating heat exchanger 6 shell side, enters through secondary water tank 3 Enter main water box 2 shell side, in main water box 2 shell side temperature is higher and density is less waterborne floating, is back to evaporation and heat-exchange through secondary water tank 3 Device 6 shell side completes free convection water circulation.

Electric heater R₁、R₂Resistance value selection, be considered as its under rated voltage output during parallel operation with Compressor rated power is roughly the same, so that general power is steady when keeping Teat pump boiler to run.Meanwhile, electric heater R₁、R₂And The resistance of connection is slightly above the resistance of inducting of compressor, at least effectively can be dropped with partial pressure more than 1/2 when resistance is connected with motor Low compression machine power consumption.

Integrated water tank in Fig. 2 and Fig. 4 about can accommodate 8 liters of tap water, does not start compressor, only uses heater, and shape is not Become free convection, about 3 liters of the region that heater can affect, i.e. secondary about 3 liters of water tank volume.With two 40 ohm of electric heaters simultaneously Connection, heating power during voltage 220V is 2.4kW, and 20 DEG C of tap water temperature sets 45 DEG C of output water temperature, preheating time is about 132 seconds, 2 minutes more youngsters, close to instant-heating.

Compressor normally runs power 1.8kW, when proceeding to holding state, electric current 6.5A, and 20 ohm of electric resistance partial pressure is 130V, compressor maintenance voltage is 90V, and power is 0.6kW, and about the 1/3 of rated power effectively heats about 0.4kW；Electrical heating Device heating power 0.85kW；System input power 1.43kW, total thermal power 1.25kW；(first operation has 5 to system by 8 liters 45 DEG C Rise 20 DEG C of water temperature) water extraction rise to 65 DEG C of user's limiting temperature, time-consuming 9 minutes it is meant that the standby time limit can reach 9 minutes, Period is because maintain compressor operation about to waste 0.03 degree of electricity, less than 5 points of.In actual use, during holding state Between can be compressed into 3～5 minutes even shorter, so how many energy consumptions will not be produced, or even also want energy-conservation than variable frequency adjustment.
