Problems solved by technology

However, due to the limitation of the insulation material of the water tank, and the temperature of the hot water stored in the water tank is higher than the ambient temperature, the heat of the hot water in the water tank is continuously lost to the environment, resulting in a waste of energy.
[0005] How to avoid energy waste in the hot water storage process and realize the effective utilization of waste heat generated in the bathing process has become a technical problem to be solved urgently

Abstract

The present invention proposes a heat pump water heater with waste heat recovery function. The heat pump water heater includes a heat pump circulation system, a hot water heat exchanger, and a waste heat recovery heat pipe; The inside of the tank; the evaporation section of the waste heat recovery heat pipe is set at the waste heat gathering place in the bathroom; the condenser of the heat pump cycle system is set inside the hot water heat exchanger. The invention uses a heat pump circulation system for heating, so that the temperature of the working medium in the cold water tank is moderately lower than or equal to the ambient temperature, avoiding the energy waste in the hot water storage process, and using the waste heat recovery heat pipe to recover the waste heat generated in the bathing process to realize bathing Efficient use of waste heat from the process.

Description

technical field [0001] The invention relates to the technical field of heat pump water heaters, in particular to a heat pump water heater with waste heat recovery function. Background technique [0002] In people's daily life, domestic hot water accounts for a large proportion of daily water use, and hot water heating devices are gradually becoming popular. There are four types of water heaters commonly used at present, namely electric water heaters, solar water heaters, gas water heaters and heat pump water heaters. Among them, electric water heaters are divided into two types, heat storage electric water heaters (including hot water tanks) and instant electric water heaters. Through the heating device, heat is generated under the condition of electricity to heat water, and at the same time, the temperature sensor is used to control the start and stop of heating. Thereby realizing the regulation to water temperature. Electric water heaters are low in cost, simple to insta...
