Method for controlling split instantaneous heat-pump water heater and water heater thereof

Abstract

The invention discloses a method for controlling a split instantaneous heat-pump water heater. The method comprises a starting operation method and a stopping operation method. The split instantaneous heat-pump water heater applying the method comprises a heat-pump water heater host machine, a hot water tank and a central control device which are connected and communicated with one another, wherein a condenser is arranged in the hot water tank; the hot water tank is a horizontal hot water tank with the volume of between 35 and 70 L for a single person; a high-power host machine is adopted andis provided with an ambient temperature sensor; the hot water tank is provided with a water temperature sensor; and a shell of the hot water tank is provided with a display screen for displaying a water temperature and a water level. The start and stop of the water heater are controlled intelligently and the split instantaneous heat-pump water heater is designed accordingly. A design scheme of a large heat-pump water heater host machine and a small hot water tank is adopted, so that the heat-pump water heater is installed like an ordinary electric water heater and the problems of difficult installation, waste of water source or energy source, low water producing speed, inconvenient use and the like are solved.

Description

Technical field [0001] The invention relates to a control method of a split heat pump water heater and the water heater, in particular to a control method of a split quick heating heat pump water heater and the water heater. Background technique: [0002] Generally, the energy-saving control of heat pump water heaters adopts a time switch control method. This control maintains the high hot water temperature in the hot water tank during the time period of the time switch, and does not guarantee the water temperature in the hot water tank outside the time period of the time switch. There may be cold water in the hot water tank. This control can greatly reduce the heat loss of the hot water tank, and can achieve a better energy-saving effect. However, with the improvement of people's living standards, hot water is needed at all times, and the energy-saving effect of the timing switch control is lost. [0003] At present, domestic heat pump water heaters generally have two types: spl...
