Solar heating system

Abstract

The invention discloses a solar heating system, which comprises solar vacuum tubes and a floor heating radiating pipe which are communicated with each other through a hot water pipe and a water return pipe, wherein the hot water pipe and / or the water return pipe is provided with a blocking valve; a communication valve is arranged between the hot water pipe and the water return pipe between the blocking valve and the floor heating radiating pipe; a small circulating pump and a heat conduction oil heater are arranged on a pipeline between the communication valve and the floor heating radiating pipe; and the communication valve, the small circulating pump, the floor heating radiating pipe and the heat conduction oil heater form a heating circulating system together. In the solar heating system, a heat storage water tank of the conventional heating system is canceled, and the heat loss during work is reduced; furthermore, the running of the system is controlled by a microcomputer, so the system works stably and reliably and has low running cost; moreover, due to a small circulating system for auxiliary heating, the heat energy utilization rate is high and the energy is saved when the auxiliary heating is started.

Description

technical field [0001] The invention relates to a solar heating technology. The specific expression is a low-energy, high-efficiency new solar heating system with microcomputer control cabinet master control, solar vacuum tube heat collection, silent circulation pump as power, and electric heating heat conduction oil tank as auxiliary. Background technique [0002] Heating in winter accounts for a large proportion of my country's energy consumption. Especially in the northern region, heating has become a major problem for the government and households, and a large amount of raw coal, wood, and power are consumed every year. At the same time, a large amount of waste gas and waste residue are emitted. Cause serious environmental pollution, according to the statistical analysis of all kinds of energy consumption of the National Bureau of Statistics, only the annual energy consumption of urban heating accounts for more than 12% of the national total energy consumption.

Problems solved by technology

This battery energy storage heating method greatly increases the cost due to the use of high-power batteries

The third deficiency is that the above-mentioned auxiliary heating system circulates water directly through the electric heating system, and there is also a hot water storage tank in the whole system, and this system with added hot water storage tank has a large amount of water storage, and the solar energy process is used during the day The temperature rises very slowly in the middle, and the temperature drops quickly, so the use effect is not ideal. For example, the water temperature of the water tank can rise to a maximum of 80°C, but after 20 minutes of starting the cycle, the temperature of the water tank drops to 20°C. During the second cycle, the water temperature cannot immediately At this time, electric heating is required to assist heating, and the electric heating process consumes a lot of energy, and the temperature rises slowly. Due to the high power of the electric heating part, it is also prone to failure
