Description

Technical Field

[0001] The present invention relates to the technical field of hot water tank control, and in particular to an adaptive hot water tank water storage heating control method, device and system. Background Art

[0002] With the acceleration of urbanization, community water consumption continues to increase, especially hot water consumption, so hot water resource management has become an important issue. A hot water tank is a device used to store and heat water. As the name suggests, it heats the input water to a preset temperature for use.

[0003] The existing hot water tank water storage and heating method does not take into account the changing characteristics of water consumption, that is, the hot water tank is full of hot water at any time, even during the low water consumption period, when the water consumption is low, the hot water tank is still full of hot water.

[0004] The above-mentioned hot water tank water storage and heating method, that is, heating the water in the hot water tank and filling it up around the clock. Since the hot water in the hot water tank continuously exchanges energy with the outside world, the water temperature will continue to decrease. When the water temperature in the hot water tank drops to a preset temperature, the heat pump will start to heat the hot water in the hot water tank. When the hot water in the hot water tank is heated to a preset temperature, the heat pump stops working. The more hot water stored in the hot water tank, the higher the water level in the hot water tank, the larger the heat exchange area with the outside world, the faster the heat loss, and the higher the rate of water temperature reduction, which will cause the heat pump to run to supplement the heat loss more times and increase the system energy consumption; the water in the hot water tank is always stored in the water tank, that is, the hot water is not replenished in the hot water tank for a long time, which will cause the water quality in the hot water tank to deteriorate, affecting the use of hot water.

[0179] S210, respectively obtaining the temperature of water in the hot water tank before the peak water usage and the trough water usage.

[0180] Specifically, a temperature sensor is used to obtain the temperature of the water in the hot water tank before the peak water usage and the trough water usage. It should be noted that as the hot water in the hot water tank will lose heat over time, the temperature of the hot water in the hot water tank will decrease. If the calculation and heating are performed according to a fixed cold water temperature (such as 7°C), errors will inevitably occur. For example, the temperature of the hot water in the hot water tank after heating does not reach the preset temperature (such as 60°C).

[0181] Therefore, this embodiment calculates the start and end times when the heat pump heats the water in the hot water tank to the preset temperature before the water usage peak arrives, and compares them with the heat pump working period before the water usage peak arrives, and compares the start and end times when the heat pump heats the water in the hot water tank to the preset temperature before the water usage trough arrives with the heat pump working period before the water usage trough arrives, and optimizes the heat pump working instructions according to the comparison results to eliminate errors.

[0187] Where t represents the time required to heat the water in the hot water tank to the preset temperature, Q represents the amount of heat required to heat the water in the hot water tank to the preset temperature, and Q g Indicates the heat supply of the heat pump per hour, Q s Indicates the heat loss of the hot water tank per hour.

[0188] S213, determining the end time of the heat pump heating the water in the hot water tank to a preset temperature before the peak of water consumption arrives:

[0191] S214, determining the end time when the heat pump heats the water in the hot water tank to a preset temperature before the water consumption trough arrives:

[0192] T2′=T2+t2

[0193] Among them, T2′ represents the end time when the heat pump heats the water in the hot water tank to the preset temperature before the water usage trough comes, T2 represents the start time when the heat pump heats the water in the hot water tank to the preset temperature before the water usage trough comes, and t2 represents the time required for the water in the hot water tank to be heated to the preset temperature before the water usage trough comes.

[0194] S215. Compare the start time and end time when the heat pump heats the water in the hot water tank to the preset temperature before the peak water usage arrives with the heat pump working period before the peak water usage arrives, and compare the start time and end time when the heat pump heats the water in the hot water tank to the preset temperature before the trough water usage arrives with the heat pump working period before the trough water usage arrives, and optimize the heat pump working instructions according to the comparison results.

[0195] For example: by using the above formula, it is calculated that the start time when the heat pump heats the water in the hot water tank to the preset temperature before the peak water usage arrives is 14:00 and the end time is 16:25, and the working period of the heat pump before the peak water usage arrives is from 14:00 to 16:00. The start time and end time when the heat pump heats the water in the hot water tank to the preset temperature before the peak water usage arrives are compared with the working period of the heat pump before the peak water usage arrives, and the heat pump working instruction is optimized to 14:00 to 16:25 to ensure that the temperature of the hot water after heating can reach the preset temperature (such as 60°C) to eliminate the error caused by heat loss.

[0196] It should be noted here that the detailed description of each step of this embodiment can refer to other embodiments and will not be repeated here.

[0197] The embodiment of the present invention provides an adaptive hot water tank water storage heating control method, including: obtaining the hot water consumption in each time period and the functional relationship between the hot water consumption and each time period; calculating the hot water heat consumption in each time period; determining the amount of hot water that needs to be stored in the hot water tank before the peak of water consumption; calculating the working period of the heat pump before the peak of water consumption; determining the amount of hot water that needs to be stored in the hot water tank before the trough of water consumption; calculating the working period of the heat pump before the trough of water consumption; calculating the amount of water replenished in the hot water tank before the peak of water consumption and the amount of water replenished in the hot water tank before the trough of water consumption; generating corresponding water pump water inlet instructions according to the amount of water replenished in the hot water tank before the peak of water consumption and the amount of water replenished in the hot water tank before the trough of water consumption , and generate corresponding heat pump working instructions according to the heat pump working period before the water consumption peak and the water consumption trough.

[0198] At the same time, the embodiment of the present invention compares the start and end times when the heat pump heats the water in the hot water tank to a preset temperature before the water usage peak arrives with the heat pump working period before the water usage peak arrives, and compares the start and end times when the heat pump heats the water in the hot water tank to a preset temperature before the water usage trough arrives with the heat pump working period before the water usage trough arrives. The heat pump working instructions are optimized based on the comparison results to ensure that the temperature of the hot water after heating can reach the preset temperature and eliminate the error caused by heat loss.
