Hybrid heat source heat supply device and method in building

Abstract

The invention provides a hybrid heat source heat supply device in a building. The hybrid heat source heat supply device comprises a solar heat collector, a heat accumulator, a heating radiator, a heat exchanger, a biogas fermentation tank and a combustor, wherein a first heat accumulation chamber and a second heat accumulation chamber are arranged in the heat accumulator, and a heater is arranged outside the heat accumulator; heat exchange pipes are annularly arranged outside the first heat accumulation chamber and the second heat accumulation chamber and communicate with the heater; the solar heat collector communicates with the second heat accumulation chamber and the first heat accumulation chamber; the combustor communicates with the biogas fermentation tank; the water supply end of the combustor communicates with a tap water pipeline and the second heat accumulation chamber, and the water outlet end of the combustor communicates with the second heat accumulation chamber and the first heat accumulation chamber; the heat accumulator communicates with a heat supply water outlet pipeline through the first heat accumulation chamber, and the second heat accumulation chamber communicates with a heat supply water return pipeline; and the heating radiator and the heat exchanger are connected between the heat supply water outlet pipeline and the heat supply water return pipeline in parallel. By means of the hybrid heat source heat supply device, the problem that the heat supply requirement of a centralized heating area cannot be met can be solved, the defect of supply interruption during single-energy heat supply is overcome, multiple kinds of energy are mixed for heat supply, and the heat supply effect is good.

Description

technical field [0001] The invention relates to the technical field of heating, in particular to a mixed heat source heating device and a heating method in a building. Background technique [0002] Residential heating systems are mainly divided into two types, centralized heating system and household heating system. Centralized heating is to transfer the centralized heat source to users through pipelines. Household heating includes wall-hung boilers or electric heating. Central heating is economical, energy-saving, environmentally friendly and safe, and the heating effect is better. However, the one-time investment of central heating is large, and the laying of pipelines is greatly affected by terrain. For example, central heating cannot be realized in rural or mountainous areas. Household heating generally adopts a single heat source, which has the problems of large energy consumption and poor indoor heating effect. [0003] In practical applications, solar energy and biom...

AI Technical Summary

Problems solved by technology

This setting uses solar energy and biogas energy to heat tap water, and stores the heated water in the accumulator, and uses electric energy to heat and keep warm, so that the accumulator can be used as a mixed heat source for heating, which can effectively solve the problem that cannot be realized. The heating demand of the central heating area can improve the defect of supply interruption when a single energy source is used for heating
