Air source heat pump heating type water heater device

Abstract

An air source heat pump heating type water heater device comprises a compressor and a heat exchange device which are connected with each other. The air source heat pump heating type water heater device is characterized in that the heat exchange device is formed by a water heater heat exchanger, a high temperature heat exchanger, a medium temperature heat exchanger and a medium and low temperature heat exchanger which are connected in series in turn through a refrigerant pipe and a water pipe; the refrigerant pipe is communicated with heat exchange pipes in turn, wherein the heat exchange pipes are arranged in the water heater heat exchanger, the high temperature heat exchanger, the medium temperature heat exchanger and the medium and low temperature heat exchanger respectively; the high temperature refrigerant generated by the compressor passes through the heat exchangers under the conduction of the refrigerant pipe in turn; the drinking water enters the heat exchangers under the conduction of the water pipe in turn so as to implement the grading heat exchange; the mutual reverse conduction is performed on the high temperature refrigerant and the drinking water. According to the air source heat pump heating type water heater device, the heat exchangers are connected in series through the refrigerant pipe and the water pipe, the grading heat exchange is performed on the drinking water due to the inverse flow directions of the high temperature refrigerant and the drinking water, and accordingly the heat exchange efficiency is improved and the efficient and energy-saving effect is achieved and every heat exchanger is provided with a water outlet for different temperature requirements of spaces and heating.

Description

technical field [0001] The invention relates to a water boiling device, in particular to a water boiling device for heating by an air source heat pump. Background technique [0002] The working principle of the traditional electric water boiler is that after the tap water is filtered by the filter device, the tap water is heated to 100°C by the electric heating device for the user to drink. Although the traditional electric water boiler meets the needs of users for drinking boiled water, it still has the following problems: it needs to directly heat tap water at a low temperature of 15°C to boiled water at a high temperature of 100°C through an electric heating device, which takes a long time for heating and consumes a lot of energy. Chinese Patent Document No. CN202452865U disclosed on September 26, 2012 a split-controlled phase-change heat system based on staged heat transfer. The system includes a cold source heat exchanger, a heat source heat exchanger, a vapor-liquid h...
