Abstract

The invention relates to a direct-heating circulation heating pressure-bearing system, a control method thereof and a heat-pump water heater. The system comprises heat source equipment, a heating water tank and at least one heat storage water tank, wherein the heat source equipment is connected with the heat storage water tank through a direct heat pipeline and is connected with the heating watertank through a circulation pipeline, the heating water tank is used for buffering water temperature fluctuation in the heat source equipment, the heat storage water tank is connected with the heatingwater tank through a first pipeline and is connected with a tail end water system through a second pipeline and is connected with a water supply system through a third pipeline, and the second pipeline communicates with the third pipeline. According to the technical scheme, high-temperature hot water is supplied to a maximum amount through the direct-heating circulation heating pressure-bearing system, the comfort of use is guaranteed through the pressure-bearing system, meanwhile, low condensation operation is realized by adopting direct heating, so that the operation energy consumption is reduced, the heat dissipation amount of the closed type heat storage water tank is small, and the operation energy consumption is further reduced.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a direct heating cycle heating pressurized system, a control method thereof, and a heat pump water heater. Background technique [0002] As an air-energy heat pump water heater unit, how to supply high-temperature hot water the fastest and maintain the comfort of the user experience has always been the focus of research on the hot water system. [0003] At present, there are two mainstream engineering systems on the market: one is the circulation heating type (open system, closed system), and the other is the direct heating circulation heating type (open system). [0004] Explanation of the principle of the circulating heating heat pump hot water unit: the water in the water tank is pumped to the hot water unit for heating through the circulating water pump, and the heated hot water is returned to the water tank. The water temperature is gradually increased to high water t...
