Air source heat pump water dispenser and heating method thereof

Abstract

The invention provides an air source heat pump water dispenser and a heating method of the water dispenser. The water dispenser comprises a water inlet unit, an air source heat pump unit, a condensation water tank, a water storage tank, a solenoid valve assembly and an instant heating unit, the air source heat pump unit is connected with the condensation water tank, the water inlet unit, the condensation water tank and the water storage tank are connected through the solenoid valve assembly, and the instant heating unit is arranged between the water storage tank and a drinking water outlet. The air source heat pump technology is introduced into the water dispenser, air energy among low-grade energy is fully utilized, the utilization way of the low-grade energy is expanded, dissipation of heat energy is reduced, and the utilization efficiency of electric energy is improved.

Description

technical field

[0001] The invention relates to heat pump technology, in particular to an air source heat pump drinking water device and a heating method thereof. Background technique

[0002] At present, the traditional way of centrally providing drinking water by boilers is gradually being replaced by decentralized drinking water dispensers, especially in schools, hospitals, office buildings and other public buildings, decentralized electric water boilers are often used to provide drinking water. But the water boiler is usually directly heated by electricity, and adopts a normally open type, which consumes a lot of electric energy.

[0003] Under the background of tightening energy sources, heat pump technologies including air source heat pumps and ground source heat pumps have broad prospects for development because of their advantages of significantly improving energy utilization efficiency. Applying air source heat pump technology to drinking water installations can ma...
