Problems solved by technology

The water level mode and water temperature of the traditional hotel heat pump water heater are pre-set. If the occupancy rate of the hotel is relatively low, the hot water will be rich and wasteful; if the occupancy rate is high, the hot water will not be enough.
The adjustment of the water level mode and water temperature of the water tank of the traditional hot water machine is manually adjusted by the wire controller to set the water level mode and water temperature. The operation is complicated and it is easy to cause waste of resources.

Abstract

The invention relates to a heat pump water heater and a control method and a system thereof. The control method of the heat pump water heater comprises the steps of: obtaining an occupancy rate; inquiring an occupancy rate zone matched with the occupancy rate; obtaining a target water level corresponding to the inquired occupancy rate section; and adjusting a water level of a water tank of the heat pump water heater according to the target water level. The control method of the heat pump water heater automatically adjusts the water level of the water tank of the heat pump water heater according to the obtained occupancy rate to realize the energy saving purpose. The invention further provides the heat pump water heater and the system.

Description

technical field [0001] The invention relates to a water heater, in particular to a heat pump water heater and its control method and system. Background technique [0002] Due to the energy-saving advantages of heat pump water heaters, many hotels have generally used heat pump water heaters for hot water production. The water level mode and water temperature of the traditional hotel heat pump water heater are pre-set. If the occupancy rate of the hotel is relatively low, the hot water will be rich and wasteful; if the occupancy rate is high, the hot water will not be enough. The adjustment of the water level mode and water temperature of the water tank of the traditional hot water machine is done by manually adjusting the wire controller to set the water level mode and water temperature. The operation is complicated and it is easy to cause waste of resources. Contents of the invention [0003] Based on this, it is necessary to provide a heat pump water heater and its contr...
