Problems solved by technology
However, in this way, the water in the cold water pipe and the hot water pipe will be hot water, which cannot be reasonably distributed, causing the user to mix the cold water and hot water through the water mixing valve, and the user experience is poor. The preheating process requires an additional increase in the amount of heated hot water, which consumes a lot of energy

The invention discloses a control method of a hot water system based on water quantity, and a control method of the hot water system based on frequency and time. The control method of the hot water system based on water quantity comprises the steps of starting a water pump until a temperature of a detection point reaches a target temperature, and recording the quantity of hot water heated by a water heater in the period of starting the water pump until the temperature of the detection point reaches the target temperature, wherein the quantity of the hot water heated by the water heater is called an initial quantity of hot water; and when passive heating of the water heater is finished, carrying out active heating by the water heater until the temperature of the detection point reaches thetarget temperature, and recording the water flow, frequency and duration in the period when the water heater carries out active heating until the temperature of the detection point reaches the targettemperature. The control method of the hot water system based on the frequency and time primarily detects the water quantity, frequency and duration of heating by the water heater. The above methods are mainly used in a hot water system lacking a return pipe.
Description
technical field [0001] The invention relates to the technical field of water heaters, in particular to a method for controlling a hot water system based on water volume, frequency and time. Background technique [0002] Existing hot water systems with zero cold water function generally include cold water pipes, hot water pipes, water pumps and water heaters. When users need zero cold water function, the water is generally preheated by the water pump, and the heated water is stored in the water pipes. However, in this way, the water in the cold water pipe and the hot water pipe will be hot water, which cannot be distributed reasonably, causing users to be unable to mix cold water and hot water through the water mixing valve, and the user experience is poor. The preheating process requires an additional increase in the amount of heated hot water, which consumes a lot of energy. Contents of the invention [0003] The purpose of the present invention is to provide a control m...
