Solar centralized heat collection household water tank exchange heat supply system

Abstract

The invention discloses a solar centralized heat collection household water tank exchange heat supply system, which comprises a solar heat collection device, wherein the solar heat collection device is communicated with a household heat exchange device through a heat supply pipeline. The solar heat collection device comprises a plurality of solar heat collectors, solar heat collection heat insulation water tanks, an anti-freezing closure electromagnetic valve and a solar circulating pump which are orderly connected in series through a pipeline. A pipeline of the solar heat collection device is provided with a branch pipeline, and the branch pipeline is provided with a normally closed heat temperature control electromagnetic valve. The system has the advantages of no (water, electricity and coal) metering problem, simple and reasonable structure, and steady heat exchange.

Description

technical field [0001] The invention relates to a solar heating system, in particular to a solar centralized heat collection-household water tank heating system. Background technique [0002] With the rapid development of my country's economy, the supply of energy resources is becoming increasingly tense. Solar heating is becoming more and more popular. However, the structure of the current solar heating system is complicated. Because only one heat exchange is performed through the solar collector and the solar thermal insulation water tank, the hot water is unstable. In case of cloudy and rainy days or when the temperature is not high, it is heated by auxiliary energy, which maintains the entire large system. Hot water circulation, low sample utilization rate. And usually common water heater also needs to involve the metering problem of water, electricity, coal, and operation and use are all more complicated.

However, the structure of the current solar heating system is complicated. Because only one heat exchange is performed through the solar collector and the solar thermal insulation water tank, the hot water is unstable. In case of cloudy and rainy days or when the temperature is not high, it is heated by auxiliary energy, which maintains the entire large system. Hot water circulation, low sample utilization

Moreover, ordinary water heaters also need to involve the metering of water, electricity, and coal, and the operation and use are more complicated.
