Description

Technical Field

[0001] This application relates to the field of home appliances, and more specifically, to a method and apparatus for detecting leaks in a domestic water heater, a storage medium, and an electronic device. Background Technology

[0002] With social development and technological advancements, the production and application of ground source heat pumps have become increasingly mature. By installing a domestic hot water jacket between the compressor and the four-way valve, hot water is provided to users, improving energy utilization. However, prolonged exposure to high-temperature hot water can easily corrode the jacket and pipes, causing leaks in the domestic hot water jacket, pipes, and water tank.

[0030] Commonly used detection methods cannot detect leaks in a timely manner. According to one aspect of this application, an embodiment of a leak detection method for domestic water heaters is provided. This application provides a leak detection method for domestic water heaters, based on the heat exchange rate Q on the refrigerant side of the jacket. mHeat exchange Q between the water side and the casing h The difference between the theoretical and actual temperature rise values ​​ΔT and ΔT in the water tank is used to determine whether and to what extent the casing and pipes are leaking. If the casing and pipes are not leaking, the difference is used to determine whether the water tank is leaking and to assess the extent of leakage. v The difference in the values ​​determines whether the water tank is leaking and the extent of the leak. Based on the leak situation, the system sends the corresponding information about the leak's extent and location to the user.

[0031] Figure 1 This is a flowchart of a water leakage detection method for a domestic water heater according to an embodiment of this application, such as... Figure 1 As shown, the method may include the following steps:

[0032] Step S1: Obtain the heat exchange rate Q of the refrigerant side of the domestic water heater. m Heat exchange Q between the water side and the casing h .

[0033] Step S2, based on the heat exchange rate Q on the refrigerant side of the casing... m Heat exchange Q between the water side and the casing h This process involves determining the leakage status of the pipes and tubing in the domestic water heater. The location and severity of the leak in the pipes or tubing or water tank can then be sent to the user.

[0034] The embodiments of step 2 include the following cases:

[0035] 1) In bQ m ≤Q h <aQ m In the case of a leak, the leakage level of the sleeve pipe in the domestic water heater is determined to be the first level, where a is greater than b and less than 1.

[0036] 2) In cQ m ≤Q h <bQ m In the case of [condition], the leakage level of the sleeve pipe in the domestic water heater is determined to be the second level, where c is greater than 0 and less than b, and the leakage rate corresponding to the second level is greater than the leakage rate corresponding to the first level.

[0037] 3) In Q h <cQ m In this case, the leakage level of the sleeve pipe in the domestic water heater is determined to be the third level, where the leakage rate corresponding to the third level is greater than the leakage rate corresponding to the second level.

[0038] 4) In Q m ≥Q h ≥aQ m In this case, confirm that the casing pipes in the domestic water heater are not leaking.

[0039] Based on the heat exchange rate Q of the refrigerant side of the casing mand the heat exchange amount Q at the water side of the sleeve h , after determining the water leakage condition of the sleeve pipeline in the domestic water heater, when it is determined that the sleeve pipeline in the domestic water heater has no water leakage, the theoretical temperature rise ΔT and the actual temperature rise ΔT of the water tank in the domestic water heater can be obtained v ; according to the theoretical temperature rise ΔT and the actual temperature rise ΔT of the water tank in the domestic water heater v , the water leakage condition of the water tank in the domestic water heater is determined, and similarly, it also includes the following cases:

[0040] 1) When dΔT ≤ ΔT v < eΔT, it is determined that the water leakage grade of the water tank in the domestic water heater is the fourth grade, wherein d is greater than 1 and less than e;

[0041] 2) When eΔT ≤ ΔT v < fΔT, it is determined that the water leakage grade of the water tank in the domestic water heater is the fifth grade, wherein f is greater than e, and the water leakage speed corresponding to the fifth grade is greater than the water leakage speed corresponding to the fourth grade;

[0042] 3) When fΔT ≤ ΔT v < gΔT, it is determined that the water leakage grade of the water tank in the domestic water heater is the sixth grade, wherein g is greater than f, and the water leakage speed corresponding to the sixth grade is greater than the water leakage speed corresponding to the fifth grade;

[0043] 4) When ΔT ≤ ΔT v < dΔT, it is determined that the water tank in the domestic water heater has no water leakage.

[0044] Through the above steps, the heat exchange amount Q at the refrigerant side of the sleeve of the domestic water heater is obtained m and the heat exchange amount Q at the water side of the sleeve h ; according to the heat exchange amount Q at the refrigerant side of the sleeve m and the heat exchange amount Q at the water side of the sleeve h , the water leakage condition of the sleeve pipeline in the domestic water heater is determined, which can solve the technical problem that the domestic water heater cannot be subjected to water leakage detection in related technologies.

[0045] As an optional embodiment, the technical solution of the present application is further described in detail below with reference to specific implementations:

[0046] In the water heater leakage detection solution provided in this application, a flow sensor is installed at the compressor exhaust port to read the refrigerant flow rate, temperature and pressure sensors are installed at the refrigerant inlet and outlet of the casing, the heat exchange of the refrigerant in the casing is calculated using the multi-enthalpy difference method, a flow sensor is installed at the outlet of the casing to read the water flow rate, temperature sensors are installed at the inlet and outlet of the casing to read the inlet and outlet water temperatures, the water-side heat exchange in the casing is calculated based on the water flow rate and temperature difference, a temperature sensor is installed in the water tank to read the water tank temperature, the theoretical temperature rise of the water tank is calculated based on the water-side heat exchange, the presence and extent of water leakage are determined by comparing the refrigerant-side heat exchange and the water-side heat exchange, and the presence and extent of water tank leakage are determined by comparing the theoretical temperature rise and the actual temperature rise.

[0047] Figure 2 This is a system schematic diagram of the present invention. 1-Compressor, 2-Evaporator, 3-Four-way valve, 4-Electronic expansion valve A, 5-Water source sleeve, 6-Electronic expansion valve B, 7-Domestic hot water sleeve, 8-Pressure sensor A, 9-Temperature sensor B, 10-Refrigerant flow sensor, 11-Pressure sensor B, 12-Temperature sensor B, 13-Inlet water temperature sensor C, 14-Outlet water temperature sensor D, 15-Water flow sensor, 16-Temperature sensor E, 17-Water pump, 18-Water tank, 19-Inlet valve, 20-Outlet valve, 21-Flow switch.

[0048] When the system is cooling, the high-temperature and high-pressure gas from the compressor enters the domestic hot water jacket for heat exchange. The gas from the domestic hot water jacket passes through the four-way valve and enters the ground water jacket for heat exchange. The high-pressure, room-temperature liquid from the ground water source passes through the electronic expansion valve for throttling and enters the finned heat exchanger for heat exchange. After heat exchange with the air, the refrigerant gas enters the compressor.

[0049] The entire process of the plan is as follows Figure 3 As shown:

[0050] Leak detection begins. The inlet and outlet valves of the water tank are closed. The reading intervals Δt and D of the flow sensor, temperature sensor, and pressure sensor are set. Starting from time t0, system data is read once every Δt time interval. At time t1, the system reads the refrigerant flow rate and the temperature and pressure of the refrigerant at the inlet and outlet of the casing.

[0051] The inlet and outlet enthalpy values ​​h of the corresponding refrigerant (superheated steam or saturated steam) at temperature and pressure are obtained from the enthalpy-entropy diagram. in1 and h out1 The heat transfer Q on the refrigerant side of the jacket is calculated using the enthalpy difference method. m1 =q m1 *(h in1 -h out1 )*Δt.

[0052] The heat exchange capacity Q at the sleeve water side is obtained by reading the temperatures at the water inlet and outlet of the sleeve and the flow rate at the water outlet h1 = c*q h1 *(T out1 -T in1 )*Δt, the theoretical temperature rise of the water tank ΔT1=Q h1 / (c*m), the actual temperature rise ΔT v1 =T v1 -T v0。 Calculate the heat exchange capacity Q on the refrigerant side from time t0 to t n m =Q m1 +Q m2 +…+Q mn , the heat exchange capacity Q at the sleeve water side h =Q h1 +Q h2 +…+Q hn .

[0053] The theoretical temperature rise of the water tank ΔT=ΔT1+ΔT2+…+ΔT n , the actual temperature rise ΔT v =T vn -T v0 Considering the influence of system errors and heat loss, the heat exchange capacity is corrected to a certain extent (0<c<b<a<1), for example, a=0.98. When Q m ≥Q h ≥aQ m , there is no water leakage in the sleeve pipeline. When bQ m ≤Q h <aQ m , the sleeve has mild water leakage (i.e., the leakage grade is grade 1). When cQ m ≤Q h <bQ m , the sleeve pipeline has moderate water leakage (i.e., the leakage grade is grade 2). When Q h <cQ m , the sleeve pipeline has severe water leakage (i.e., the leakage grade is grade 3).

[0054] When there is no water leakage in the sleeve heat exchanger pipeline, set 1<d<e<f<g. When ΔT≤ΔT v <dΔT, there is no water leakage in the water tank. When dΔT≤ΔT v <eΔT, the water tank has mild water leakage (i.e., the leakage grade is grade 4). When eΔT≤ΔT v <fΔT, the water tank has moderate water leakage (i.e., the leakage grade is grade 5), ΔT v ​When the leakage rate is ≥fΔT, the water tank is considered to be severely leaking (i.e., leakage level VI). For minor leaks, a notification message is sent to the user at the corresponding location; for moderate leaks, an alarm message is sent to the user at the corresponding location; and for severe leaks, an alarm message is sent to the user at the corresponding location, and the water pump is shut down.

[0055] Using the detection method of this application, water leakage of the unit can be detected in real time without the unit being in stable operation. The heat exchange and temperature rise values ​​are calculated based on the set time interval and calculation cycle of the system data reading. The difference in heat exchange and temperature rise values ​​are used to comprehensively determine whether there is water leakage in the domestic hot water pipes and water tank, the location of the leakage and the degree of leakage, and timely send alarms to users.
