Water boiler for heating by utilizing solar energy and heat pump and heating method of water boiler

Abstract

The invention discloses a water boiler for heating by utilizing solar energy and a heat pump and the heating method of the water boiler. The water boiler comprises a machine cabinet, an energy collecting system and a control system, wherein the energy collecting system comprises a solar energy heat collecting unit, a low-temperature heating unit, a high-temperature heating unit and a heat exchange box; the solar energy heat collecting unit is connected with the heat exchange box through a heat supply pipe and a backflow pipe; and a condenser of a low-temperature heat pump unit, an evaporator of a high-temperature heat pump unit and liquid-state heat carriers are packaged in the heat exchange box. By adopting the water boiler, when in sunshine, the solar energy heat collecting device absorbs the heat of the sunshine, and provides the heat for the heat exchange box; when in no sunshine, the low-temperature heating unit absorbs the heat of air around and provides the heat for the heat exchange box; the low-level heat obtained by the heat exchange box is improved to high-level heat through the high-temperature heating unit, so that water in a water boiling tank is heated. The water boiler can reduce energy source consumption greatly, can reduce pollution emission, also can easily keep a boiler body to be clean, and is beneficial to maintaining environment hygiene indoors and outdoors.

Description

technical field [0001] The invention relates to a boiling water stove and a heating method thereof, in particular to a boiling water stove using solar energy and a heat pump for heating and a heating method thereof. Background technique [0002] Boiling water stoves are a necessity for human life, but currently existing types of boiling water stoves generally have the following disadvantages: 1) consume a lot of energy, including firewood, coal, fuel oil, gas, electric energy, etc.; 1. Boiling water stoves using gas as the energy source produce open flames, which may lead to a higher probability of fire hazards. [0003] The application of solar heat collectors is becoming more and more extensive, and the technology is becoming more and more mature. Generally, solar water heaters can raise the water temperature to about 60-80°C. However, solar energy itself has the disadvantage of unstable utilization time. Contents of the invention [0004] The purpose of the present in...

Problems solved by technology

[0002] Boiling water stoves are a necessity for human life, but currently existing various types of boiling water stoves generally have the following disadvantages: 1) consume a lot of energy, including firewood, coal, fuel oil, gas, electric energy, etc.; 2) use firewood, coal, fuel oil 1. Boiling water stoves with gas as energy source produce open flames, which lead to a higher probability of fire hazards. At the same time, they will also pollute the environment when used, while boiling water stoves using electric energy have low thermal efficiency and high power consumption.

However, solar energy itself has the disadvantage of unstable utilization time.
