Energy-saving solar heat supply system

Abstract

The invention relates to an energy-saving solar heat supply system which comprises a solar heat collector, a water outlet pipe, a heat accumulator, a water conveying pipe, a heat dissipator, a water return pipe, a preheater, a circulating water pipe, a water inlet pipe, a water supply water tank and a tap water supply pipe. The solar heat collector is connected to the heat accumulator, the heat accumulator is connected to the heat dissipator, the heat dissipator is connected to the tube pass inlet of the preheater, the tube pass outlet of the preheater is connected to the upper water inlet ofthe circulating water tank, the lower water outlet of the circulating water tank is connected to the water inlet of the solar heat collector, the water outlet of the water supply water tank is connected to the tube pass inlet of the preheater, and the tube pass outlet of the heat dissipator is connected to the upper water inlet of the circulating water tank. The energy-saving solar heat supply system has the advantages of being scientific in design, improving the work power of the solar heat collector, increasing the circulating heat efficiency of the system, improving the utilization ratio ofwaste heat energy and increasing the energy-saving efficiency.

Description

technical field [0001] The invention relates to the technical field of energy saving, in particular to an energy-saving solar heating system. Background technique [0002] In the cold season of winter, rural residents in northern my country often install coal-fired boilers and radiators at home, and burn a large amount of coal to burn hot water to solve the heating problem of the family. This kind of coal-fired boiler is small in size, resulting in insufficient coal combustion. , heavy pollution, serious heat loss, serious waste of coal resources, extremely low energy saving, and serious environmental pollution; the thermal cycle in the existing solar heating system is single-closed, and the temperature of the high-temperature hot water after passing through the radiator is still high, and it is directly refluxed If it is mixed with cold water in the circulating water tank, it will easily cause the local temperature of the circulating water tank to be high, the dissipation of ...
