However, for the direct heating water system, when the heat supply of the heat pump equipment is insufficient, the water volume cannot meet the requirements; for the circulating water system, when the heat supply of the heat pump equipment is insufficient, the water temperature fluctuates greatly, and the water temperature cannot meet the requirements
Like this, bring inconvenience to the user, cause the use performance of this hot water system to be poor

The invention provides a water temperature control method of a hot water system and the hot water system. The water temperature control method of the hot water system comprises the steps that the water level and water temperature T of a water tank are detected; when the water level is not higher than a first preset water level, a heat pump set of the hot water system is stopped, and water is prevented from being added into the water tank; when the water level is between the first preset water level and a second preset water level, the heat pump set is started and water is prevented from being added into the water tank if T<=T1, and the heat pump set is started and the amount of water in the water tank is maintained if T1=T2; when the water level is not lower than the second preset water level, water is prevented from being added into the water tank, the heat pump set is started if T<=T1, the state of the heat pump set is maintained if T1=T2. By the adoption of the water temperature control method of the hot water system, it can be guaranteed that the amount and temperature of water in the water tank meet use requirements, and thus the user performance of the hot water system can be improved.
Description
Technical field [0001] The invention relates to the technical field of water temperature control in a hot water system, and more specifically, to a water temperature control method of a hot water system and a hot water system. Background technique [0002] In a hot water system that uses a heat pump unit for heating, because the heat pump equipment uses a small amount of high-level energy to transfer heat from a low-level working fluid to a high-level working fluid, it has an energy-saving effect. Therefore, hot water systems using heat pump units for heating are gradually being widely used. [0003] At present, the hot water system that uses heat pump equipment for heating usually uses a direct heating water system or a circulating water system. However, for the direct heating water system, when the heat pump equipment does not supply enough heat, the water volume cannot meet the requirements; for the circulating water system, when the heat pump equipment does not supply enough h...
