Heat pump type water heater and heating control method thereof

Abstract

The invention discloses a heat pump type water heater and a heating control method thereof. The method comprises the steps of acquiring environmental temperature T, initial water temperature T0 in a water tank, the current water level h of water in the water tank, the target water temperature T in the water tank, and the target time t of the hot water consumption as set by a user; calculating the startup time t of a compressor according to the environmental temperature T, the initial water temperature T0, the current water level h, the target water temperature T and the target time t; controlling the compressor to start to heat when reaching the startup time t. The heat pump type water heater is convenient to use, and energy saving.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a heat pump water heater and a heating control method thereof. Background technique [0002] A heat pump water heater is a water heater that uses the heating principle of an air conditioner to achieve high efficiency and energy saving. The heat pump water heater currently on the market is mainly controlled by a remote control: when the user wants hot water, the remote control is used to control the start-up and heating. After T, the user starts to use hot water. After using the hot water, the user needs to control the shutdown through the remote control. Every time the hot water is used, the remote control needs to be manually operated to control the switch. , because the user cannot accurately know when the heat pump water heater can heat the hot water to the specified temperature T. For this reason, usually users will use the hot water after a period of time after the ho...

[0002] A heat pump water heater is a water heater that uses the heating principle of an air conditioner to achieve high efficiency and energy saving. The heat pump water heater currently on the market is mainly controlled by a remote control: when the user wants hot water, the remote control is used to control the start-up and heating. After T, the user starts to use hot water. After using the hot water, the user needs to control the shutdown through the remote control. Every time the hot water is used, the remote control needs to be manually operated to control the switch. , because the user cannot accurately know: when the heat pump water heater can heat the hot water to the specified temperature T

For this reason, usually users will use the hot water after a period of time after the hot water in the heat pump water heater is heated to the specified temperature T, and during this time, the heat of the hot water in the heat pump water heater is dissipated outwards, That is, the heat is wasted and the heat pump water heater is not energy-saving.
