At a first water temperature T 1 Greater than or equal to the set starting temperature T D And a first water temperature T 1 Is equal to the second water temperature T 2 When the temperature of the water in the two inner containers is higher, the first heater and the second heater are controlled to be not operated without heating.
Example two
Fig. 2 is a schematic structural diagram of a water heater according to a second embodiment of the present invention, as shown in fig. 2, the water heater includes a controller (not shown), a first liner 202, a second liner 203, a first heat exchanger 204, a second heat exchanger 205, a first electronic expansion valve 206, a second electronic expansion valve 207, a first temperature sensor 208, a second temperature sensor 209, an evaporator 210, a four-way valve 211, and a compressor 212.
The bottom of the second liner 203 is provided with a cold water inlet for connecting a cold water source, for example, a cold water pipe for domestic water. The top of the second liner 203 is provided with a water outlet, the water outlet at the top of the second liner 203 is connected with a connecting pipe 221, and the connecting pipe 221 extends to the bottom in the first liner 202. The top of the first liner 202 is provided with a hot water outlet, and hot water flows out from the hot water outlet at the top of the first liner 202 for users to use.
The first heat exchanger 204 is disposed in the first inner container 202, and the second heat exchanger 205 is disposed in the second inner container 203.
The outlet of the compressor 212 is connected with the liquid inlet D of the four-way valve 211, the liquid outlet E of the four-way valve 211 is connected with the inlet of the evaporator 210, the outlet of the evaporator 210 is respectively connected with the inlets of the first heat exchanger 204 and the second heat exchanger 205, the outlets of the first heat exchanger 204 and the second heat exchanger 205 are both connected with the air inlet C of the four-way valve, and the air outlet S of the four-way valve is connected with the inlet of the compressor 212.
The first electronic expansion valve 206 is disposed on a pipe between the first heat exchanger 204 and the evaporator 210, and the second electronic expansion valve 207 is disposed on a pipe between the second heat exchanger 205 and the evaporator 210.
The first temperature sensor 208 is disposed in the first inner container 202 and is used for collecting a first water temperature of the first inner container 202, and the second temperature sensor 209 is disposed in the second inner container 203 and is used for collecting a second water temperature of the second inner container 203.
The first electronic expansion valve 206, the second electronic expansion valve 207, the first temperature sensor 208 and the second temperature sensor 209 are all connected to a controller for executing the water heater control method provided by any of the foregoing embodiments of the present invention.
Specifically, a first water temperature T in a first liner 1 Less than the lower limit temperature T of domestic water L At this time, the controller controls the first electronic expansion valve 206 to open and the second electronic expansion valve 207 to operate at the lowest opening (the opening of the electronic expansion valve is being addedIn the heating switching process, the control is performed by the minimum opening degree instead of complete closing, so as to prevent the refrigerant from migrating into the closed heat exchanger and not participating in the whole system circulation, and causing the system operation fault), the high-pressure liquid working medium generated by the compression of the compressor 212 is evaporated into a gas state through the evaporator 210, and absorbs a large amount of heat energy from the air, and then almost all the heat energy enters the first heat exchanger 204, so that the heat source is concentrated on the first heat exchanger 204, the water storage in the first liner 202 is quickly heated, the heating efficiency is improved, and the waiting time of a user is reduced.
At a first water temperature T 1 Is greater than or equal to the lower limit temperature T of domestic water L At the time, determine the first water temperature T 1 And a second water temperature T 2 Whether or not they are all smaller than the set starting temperature T D . If the first water temperature T 1 And a second water temperature T 2 Are all smaller than the set starting temperature T D The controller controls the first and second electronic expansion valves 206 and 207 to be opened while heating water in the first and second liners 202 and 203. If the first water temperature T 1 Greater than or equal to the set starting temperature T D And a second water temperature T 2 Less than the set starting temperature T D The controller controls the second electronic expansion valve 207 to be opened, the first electronic expansion valve 206 operates at the lowest opening degree, the heat source is concentrated on the second heat exchanger 205, the water stored in the second liner 203 is rapidly heated, and the heating efficiency is improved. Meanwhile, after the hot water in the first liner 202 is used, the hot water in the second liner 203 is timely supplemented into the first liner 202, so that the heating efficiency is improved, and the waiting time of a user is reduced. If the first water temperature T 1 Greater than or equal to the set starting temperature T D And a first water temperature T 1 Is equal to the second water temperature T 2 It is explained that the temperature of water in both the inner containers is high, and heating is not required, and the controller controls both the first electronic expansion valve 206 and the second electronic expansion valve 207 to operate at the lowest opening.
In some embodiments of the present invention, as shown in fig. 2, the water heater further includes a pressure relief switch 213, and the pressure relief switch 213 is disposed on a pipe between an outlet of the compressor 212 and a liquid inlet D of the four-way valve 211. When the pressure in the pipeline is greater than a preset pressure threshold, the pressure release switch 213 is opened to release pressure.
In some embodiments of the invention, the first heat exchanger 204 and the second heat exchanger 205 are both coil heat exchangers. The coil heat exchanger and water have larger heat exchange area, which is beneficial to improving the heating efficiency.
In the embodiment of the present invention, the water outlet at the top of the second liner 203 is connected to a connecting pipe 221, the connecting pipe 221 extends to the bottom of the first liner 202, and the top of the first liner 202 is provided with a hot water outlet. In the process of using the hot water, the hot water is gradually pushed out from the top of the first inner container 202, meanwhile, the hot water of the second inner container 203 is supplemented to the bottom of the first inner container 202, and the cold water is supplemented to the bottom of the second inner container 203.
For example, the first liner 202 and the second liner 203 each have a capacity of 100L, and a single liner 200L is taken as an example. The current water temperature is assumed to be 35 ℃ and not available for bathing, and the bathing water temperature is 40 ℃. According to the calculation of the single liner 200L, supposing that the bathing water consumption of a person is 60L and the heating capacity of a unit is 10KW, 200L of water needs to be heated to the temperature T to meet the water consumption requirement. Then the following formula is present:
C×(40℃-35℃)×200L+C×(40℃-15℃)×60L＝C×(Ta-15℃)×200L
wherein, c× (40 ℃ to 15 ℃) x 60L represents the energy required to heat the additional 60L of cold water at 15 ℃ to 40 ℃ after 60L of hot water is used up. Ta was calculated to be equal to 47.5 ℃.
Namely, the time t1 required to heat 200L of water to 47.5 ℃ is:
t1＝C×(47.5℃-35℃)×200L/10KW
t1 is obtained equal to 17.5min.
If the scheme of the invention is adopted, because the water storage in the first inner container is larger than 60L, only the water in the first inner container is needed to be heated, the capacity is 100L, the water supplementing temperature is not the direct water supplementing of tap water, and the second inner container supplements water for the first inner container, so that the heating temperature difference is greatly reduced. Assuming that the water temperatures in the first liner and the second liner are 35 ℃, the following formula is provided:
c× (40 ℃ to 35 ℃) x 100l+c× (40 ℃ to 35 ℃) x 60 l=c× (Tb-35 ℃) x 100 gives Tb equal to 43 ℃.
Namely, the time t2 required to heat 100L of water to 43 ℃ is as follows:
t2＝C×(43℃-35℃)×100L/10KW
t1 is obtained equal to 5.6min.
From the above, the time required for heating is shortened, and the heating efficiency is improved.
