Abstract

The invention discloses a heat pump hot water system. A controller is configured to determine the lowest water level control height L of a water tank; determining a water replenishing gear of a water inlet switch according to the L; each gear, higher than the water replenishing gear, of the water level switch is used as a water stopping gear, and each water replenishing strategy is determined; in each water replenishing strategy, water is replenished to the water tank when the water level of the water tank is lower than the water replenishing gear, and water replenishing is stopped when the water level is higher than the water stopping gear; the water tank heat dissipating capacity of each water supplementing strategy is calculated; and the water supplementing strategy with the minimum heat dissipating capacity of the water tank is selected as the optimal water supplementing strategy, so that the purposes of saving energy and reducing consumption are achieved.

Description

technical field [0001] The invention relates to the technical field of electric appliances, in particular to a heat pump hot water system. Background technique [0002] Under the background of "double carbon", the air source heat pump water heater has gradually been recognized by the market as an energy-saving product. Furthermore, the energy-saving control during product use will be gradually tested by the market and users. [0003] Commercial heat pump water heater products are mostly used in hotels, bathing centers and other places to provide users with domestic hot water; during project installation, it is necessary to configure an open water tank (mostly made of stainless steel) and install a water level switch. In many projects, when selecting water tanks, in order to prevent insufficient hot water, the capacity of the water tank is too large. Therefore, more high-temperature hot water will continue to be retained in the stainless steel water tank, and the thermal in...
