Multifunctional quick heating type heat pump water heater

Abstract

The invention discloses a multifunctional quick heating type heat pump water heater and belongs to the technical field of application of heat pumps. The water heater is characterized in that: a liner is arranged in a quick heating type water heater; a double-layer sleeve refrigerant-water heat exchanger is arranged between an inner side face of a shell of the water heater and an outer side face of the liner; an inner sleeve is communicated with the liner through an inlet of the liner to form an inner water chamber; a refrigerant channel is formed between the inner sleeve and an outer sleeve; and an outer water chamber is formed between the outer sleeve and an inner side face of the shell of the quick heating type water heater. The invention has the advantages that: the refrigerant flow is adjusted for heating according to the needed hot water quantity, the heat loss of a water storage tank is greatly reduced, the energy is saved, and the operating cost is saved; a domestic hot water circulation loop and a heating water circulation loop are formed, one machine has multiple purposes, and the water heater has a compact structure and low initial cost; the hot water quantity is not limited by the volume of the water storage tank, and the water heater can be continuously used for a long time; and the water heater has light weight and small volume and is convenient to mount and use.

Description

technical field [0001] The invention belongs to the technical field of heat pump applications, and relates to a multi-functional fast-heating heat pump water heater. In addition to providing domestic hot water, it can also provide hot water required by radiators and floor heating. The two systems are combined into one, compact integrate. Background technique [0002] With the improvement of people's living standards, water heaters have gradually become popular in households. The vast majority of water heaters on the market are traditional electric water heaters and natural gas water heaters. Hot water is produced by direct combustion or direct heating of electric heating wires. The heating efficiency is low, the energy consumption is large, and the use cost is high. Commonly used electric water heaters cannot provide hot water quickly and effectively when water is needed, and the water needs to be heated in advance and stored in a water storage bucket before use. The fast-...
