The invention provides a hot water unit with the constant temperature hot water function and a control method thereof. The hot water unit comprises a refrigerant heat exchange cycle with heat exchangeand a water heat exchange cycle with heat exchange and further comprises a water tank, two heat exchange pipelines are arranged in the water tank, two ends of one heat exchange pipeline communicate with the water heat exchange cycle, and two ends of the other heat exchange pipeline communicate with the refrigerant heat exchange cycle. According to the hot water unit with the constant temperaturehot water function and the control method thereof, the two heat exchange pipelines are arranged in the water tank, according to user needs, work states of a first tee valve and a second tee valve areswitched, a refrigerant and water can respectively or simultaneously heat water in the water tank, the indoor heating comfort during hot water making is improved, the domestic hot water tank can be subjected to certain heat preservation, the frequent switching of heating and hot water making functions can be removed, the unit comprehensive reliability is improved, the unit start and shutdown can be reduced, and the service life of the whole unit can be prolonged.
Description
technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to a hot water unit with constant temperature hot water function and a control method thereof. Background technique [0002] At present, multifunctional water heaters generally have the functions of heating, hot water, and cooling. User-side equipment includes domestic hot water tanks, fan coils, and floor heating coils. The switching between heating, cooling and hot water is switched through the electric three-way valve. In the heating season, the function is switched from heating to hot water. To get hot water, at this time, the heating terminal equipment (fan coil, floor heating coil) on the user side stops the heat exchange cycle, and the electric three-way valve will switch to Heating cycle, so during the period of hot water heating, the indoor temperature will be affected and lowered, the fluctuation of indoor temperature will bring bad body feeling to the us...
