Heat collection and storage type unpowered solar water heater and hot water system

Abstract

A heat collection and storage type unpowered solar water heater and hot water system comprises an all-glass solar heat collection vacuum tube and an outer box body, wherein a heating medium is filled in the outer box body, an outer layer of the outer box body is provided with a heat preservation casing, and an air discharging pipe is communicated between the outer box body and the heat preservation casing. The all-glass solar heat collection vacuum tube is inserted into the lower side wall of the outer box body. A support is arranged on the rear side of the all-glass solar heat collection vacuum tube, an inner box body is arranged inside the outer box body, and the left and right side of the inner box body are respectively connected with a cold water inlet pipe and a hot water outlet pipe, an auxiliary heating device is communicated to a pipe enabling the hot water outlet pipe to be led to the heat supply end of each family, and a constant-temperature water mixing valve is connected between the cold water inlet pipe and the hot water outlet pipe at the heat supply end. A series of problems of large occupied building space, low solar heat utilizing efficiency, complicated management, high cost, unbalanced cold-hot water pressure, poor water quality and the like of a traditional solar heat collection circulating pump power consumption and heat storage system can be solved.

Description

technical field [0001] The invention relates to a solar hot water supply system, in particular to a non-powered solar hot water supply system. Background technique [0002] With the development of society, energy shortage and environmental pollution have become the bottleneck restricting sustainable development, and the application of renewable energy has been paid more and more attention. As a relatively economical and relatively mature technology, solar water heating has been applied on a large scale. In particular, the popularization and application of household water heaters account for about 90% of solar thermal utilization; solar centralized hot water systems account for about 10%. According to the investigation and research on the current solar water heating technology, the following disadvantages generally exist: [0003] 1. In low-rise residences, compact water heaters with top water and sun drying are generally used, which have problems of low thermal efficiency,...
