Detailed Description
An embodiment of the invention, an example of which is shown in fig. 1, is described in detail below. The embodiment described below with reference to fig. 1 is exemplary only for explaining the present invention, and should not be construed as limiting the present invention.
As shown in fig. 1, the utility model relates to a heat pump water heater with internet conveying, diagnosis and management function, including evaporimeter 1, compressor 2, choke valve 3, condenser 4, storage water tank 5, circulating water pump 6, room heat exchanger 7, room air temperature sensor 8, storage water tank temperature sensor 9, system controller 10, power-electric energy meter 11, wiFi module 12 and outdoor environment temperature sensor 13.
The air exhaust port of the compressor 2 is connected with the inlet of the condenser 4, the outlet of the condenser 4 is connected with the inlet of the throttle valve 3, the outlet of the throttle valve 3 is connected with the inlet of the evaporator 1, and the outlet of the evaporator 1 is connected with the inlet of the compressor 2. When the heat pump refrigerating system is operated, refrigerant gas discharged by the compressor 2 enters the condenser 4, water in the water storage tank 5 is heated through the condenser 4, meanwhile, the refrigerant in the condenser 4 is condensed into liquid, throttled through the throttle valve 3, enters the evaporator 1 for evaporation, and then enters the compressor 2.
The water outlet of the water storage tank 5 is connected with the inlet of a circulating water pump 6, the outlet of the circulating water pump 6 is connected with the inlet of a room heat exchanger 7, and the outlet of the room heat exchanger 7 is connected with the water return port of the water storage tank 5. When the water supply system is running, hot water is pumped from the water storage tank 5 into the room heat exchanger 7 through the circulating water pump 6, exchanges heat with the room air through the room heat exchanger 7, cools down, and then returns to the water storage tank 5.
The room air temperature sensor 8, the water storage tank temperature sensor 9, the system controller 10, the power-electric energy meter 11, the WiFi module 12 and the outdoor environment temperature sensor 13 are electrically connected with the system controller 10 respectively.
The power-electric energy meter 11 is installed at the input end of the main power supply of the heat pump hot water system and is used for measuring the actual operating power Ps and the accumulated consumed electric energy Ws of the variable-temperature water supply of the heat pump.
The temperature sensed by the outdoor ambient temperature sensor 13 is the outdoor ambient temperature Tw, the temperature sensed by the water tank temperature sensor 9 is the actual water supply temperature Tgs, and the temperature sensed by the room air temperature sensor 8 is the actual room temperature Tns.
Setting a room set temperature T ' ns in the system controller 10, determining a required theoretical water supply temperature T's by the system controller 10 according to the room set temperature T ' ns and the detected outdoor environment temperature Tw, and controlling the compressor 2 to start and stop by the system controller 10 according to a comparison between the actual water supply temperature Tgs and the theoretical water supply temperature Tgs; when the actual water supply temperature Tgs > Tgs, the compressor 2 stops operating; when the actual water supply temperature Tgs is equal to or less than Tgs, the compressor 2 is turned on.
In the present embodiment, the method of determining the theoretical feed water temperature T' gs is: setting outdoor environment temperature T ' w to-15 ℃, room setting temperature T ' ns to 20 ℃ and setting water supply temperature T's to 45 ℃ in a constant-temperature water supply manner as design criteria, wherein the theoretical water supply temperature T's is changed with the outdoor environment temperature Tw and the room setting temperature T's to T ' gs =0.5 (T's-Tw) + 27.5.
The system controller 10 also controls the on/off of the circulating water pump 6 by comparing the detected actual room temperature Tns with the room set temperature T' ns; when the actual room temperature Tns > the room set temperature T 'ns, the circulating water pump 6 stops operating, and when the actual room temperature Tns is equal to or less than the room set temperature T' ns, the circulating water pump 6 starts operating.
The system controller 10 further obtains the actual operating power Ps, the accumulated consumed electric energy Ws and the actual water supply temperature Tgs of the heat pump through the power-electric energy meter 11, and the system controller 10 synchronously calculates the constant-temperature operating power Ph and the constant-temperature accumulated consumed electric energy Wh of the heat pump in the constant-temperature water supply mode according to the same heat generated in the variable-temperature operation of the heat pump, and obtains the accumulated electricity saving amount Δ W of the variable-temperature water supply relative to the constant-temperature water supply. In this example, the constant temperature supply water temperature Tgs was 45 ℃. The specific calculation method of the constant-temperature operating power Ph, the constant-temperature accumulated consumed electric energy Wh and the accumulated electricity-saving quantity delta W is as follows:
（1） Ph= Ps·[( 45-Tw) / 318]/ [( Tgs-Tw) / (273+ Tgs)]；
(2) wh = Σ Ph · Δ t, Δ t is a Ph value interval time, Ph is power data obtained by detecting for 1 time within every 1 interval time Δ t, in this embodiment, Δ t is 10s, and Ph is power data obtained by detecting for 1 time every 10 s;
（3） ΔW= Wh-Ws。
